The Superpower of Sleep: How a Good Night's Sleep Extends Your Life
Foreword: A Personal Journey to Better Sleep
The Background to the Interest in Sleep
Before we delve into the deeper layers of the science and art of sleep, it may be helpful to understand why I am the right person to guide you through this complex topic. My journey into the world of sleep began not as an academic exercise, but as a personal necessity. From a relatively young age, I have navigated a minefield of sleep difficulties, from difficulty falling asleep, to frustrating nights where I would wake up after just a few hours, unable to fall back asleep. I have even experienced days, stretched out to seemingly endless periods of 3-4 days, where sleep seemed an impossibility.
This personal struggle forced me to delve deep into the mysteries of sleep. I have dedicated countless hours to exploring, learning, and experimenting, drawing on knowledge from some of the world’s leading experts in sleep research, neuroscience, and psychology. But most importantly, I have integrated these lessons with my own experiences to discover what actually works for me. Through this process, I have developed effective routines that have not only improved my own sleep quality, but have the potential to help you as well.
Why Sleep Is Your Superpower?
Understanding the causes of sleep problems is just the first step. The critical next step is to build and maintain healthy sleep habits that support both physical and mental regeneration.
Good sleep is the foundation for cell renewal, the ability to face daily challenges, and, not least, a sense of joy in life that is difficult to achieve without high-quality rest. During sleep, the body regenerates cells and cleanses the brain, which is essential for physical and mental function. The body repairs tissues and produces new cells, which support the immune system and skin health. The brain also uses this time to "reset" itself. This reset process includes the removal of toxins that accumulate during the day and the consolidation of memories, as well as the strengthening of neural connections, which is essential for learning, memory and creativity.
Regular, deep sleep prepares the brain for new challenges and supports emotional stability. So mastering the art of sleep is your superpower that contributes to a better life for yourself and those around you.
In this guide, we will explore aspects of sleep and how you can optimize sleep for your unique needs. While we are all different, with individual needs and predispositions, I am convinced that there are universal strategies and insights that can be integrated into any sleep routine. Let’s explore these strategies together, and take the first steps towards a night of deeper, more rewarding sleep, as well as the incredible benefits of better sleep.
Top 10 Tricks for Achieving Deeper and More Rejuvenating Sleep
1. Restructuring Thought Patterns for Better Sleep
Adopting a Third Person Perspective
Sleep challenges can often be the result of thoughts and stress that build up throughout the day, which become especially prominent when we put our heads on the pillow. To combat this, it is crucial to develop effective routines to calm down and distance ourselves from the day's stress in the hours before bed.
An effective way to deal with these thoughts is to change the way we relate to them. When negative thoughts or worries related to work or other areas of life become overwhelming, it can be helpful to adopt a third-person perspective. It is important to recognize that our thoughts do not define our essence; rather, we are observers of our own mental thought processes. By consciously stepping back and observing our thoughts from a third-person perspective, without judging them, but rather accepting them as they are, we can create a distance that allows for a deeper calm.
Visualization techniques
Personally, I find it helpful to visualize observing my own thoughts, this I do by physically visualizing myself stepping back and looking at myself from a distance and observing my own body language and thoughts, this to get a true third-person view of these thoughts on this process. This contributes to a significantly greater sense of relaxation and can be an effective method of reducing mental stress.
Mastering this technique may take some practice, but the benefits to sleep quality are well worth the effort.
Furthermore, engaging in activities that help us see the big picture can be helpful in putting our daily concerns into perspective. Watching documentaries or podcasts about the universe, for example, can help us pull ourselves out of our personal bubble and see our problems in a new light. This can not only be calming in itself, but also help to relativize and in some cases trivialize the problems or concerns that initially seemed intense.
Changing our thought patterns and actively seeking larger perspectives can be powerful strategies for improving our sleep quality and overall well-being.
Another effective yet simple technique for calming your mind before bed involves visualizing a clear, blue sky with clouds floating by. Imagine yourself observing these clouds one by one, without grasping or dwelling on any particular thoughts that may pass through your mind, just like the clouds drifting by in the sky. This exercise can help you distance yourself from the worries and stresses of the day, and make it easier to slip into a meditative state. By focusing on this calming image, you may find it easier to let go of tension and worries, thus preparing your body and mind for a peaceful night’s sleep.

2. Natural Daylight and Its Effect on Your Circadian Rhythm
One of the most fundamental, yet often overlooked, factors in promoting good sleep and overall well-being is exposure to natural daylight, especially in the first few hours after waking up. This window of time, typically between 8 a.m. and 10 a.m., plays a critical role in synchronizing our circadian rhythm – the body’s internal clock that regulates the cycle of sleep and wakefulness.
The Importance of Natural Daylight
Our circadian rhythm is profoundly influenced by light, with exposure to natural daylight in the morning signaling to the body that it is time to be awake and active. This helps suppress the production of melatonin, the sleep hormone, and promotes the production of hormones linked to wakefulness, such as cortisol. By starting the day with a dose of natural light, we help our internal clock adjust to the day-night cycle, which both improves alertness during the day and prepares the body for sleep at night.
The Effect On Hormone Balance Melatonin and Cortisol
Exposure to natural daylight has a direct impact on our hormonal balance, which in turn affects the quality of our sleep. By setting our circadian rhythm correctly, we ensure that our bodies produce the right hormones at the right times. In the evening, as the sun sets and exposure to natural light decreases, our bodies begin to produce more melatonin, which prepares us for sleep. This natural shift in hormone production is essential for maintaining a healthy sleep-wake cycle.

Practical Tips for Maximizing the Benefits
To take advantage of the positive effects that natural daylight has on sleep, try integrating the following habits into your daily routine:
- Start your day with a morning walk: A short walk in daylight can help adjust your circadian rhythm and improve your alertness throughout the day.
- Take breaks outdoors: If possible, try to take short breaks outdoors throughout the workday to get additional exposure to natural light.
-
Work near windows: Placing your workstation near a window can also help increase exposure to daylight, which is especially helpful during the winter months.
Use of Artificial Light in the Dark Ages
In countries located far north, such as Scandinavia, where winters are long and dark, it is not always possible to get sufficient exposure to natural morning light. In such cases, artificial light sources, specially designed wake-up lights and light therapy lights can be an effective solution. These lights mimic the sunrise and provide a gradually increasing light that helps to adjust and maintain the circadian rhythm, also known as the body's internal clock. The use of these lights can be a useful aid during months with limited daylight, helping the body to adapt to natural rhythms, despite the lack of sunlight.
Conclusion
Exposure to natural daylight is a simple yet powerful way to improve both your alertness during the day and your sleep quality at night. By synchronizing our circadian rhythm with natural light patterns, we can support our body’s natural hormone production and promote a healthier sleep-wake cycle. So next time you start your day, give yourself the benefit of stepping out into the daylight – your body and mind will thank you.
3. Physical Activity and Sleep
In addition to the previously mentioned preparation tips, I have found that physical exhaustion plays a key role in achieving good sleep. For me personally, this means engaging in intense exercise almost every day. It is important to note, however, that the timing of exercise is crucial; exercising too late at night can actually be counterproductive. By utilizing the energy stored throughout the day with the right exercise, I find that my body becomes properly fatigued, making it easier to fall asleep come evening.
The Effect of Physical Activity on Sleep Quality
Regular exercise enhances the restorative phases of sleep, especially the deep sleep phase that is critical for the body's repair processes. People who exercise regularly often find that they fall asleep faster, known as reduced sleep latency, and they can also enjoy longer and more continuous sleep.
How Exercise Affects Dreams
Interestingly, increased physical activity can lead to more vivid and memorable dreams. This is likely due to an increase in REM sleep, which is the stage of sleep where most dreams occur. Exercise can also help with emotional processing, which can reduce negative dream experiences such as nightmares.
Recommendations for Optimal Workout Time
- Avoid late-night exercise: If you find that exercise increases your energy levels, try to avoid strenuous exercise right before bedtime.
- Ideal time for exercise: Morning or afternoon sessions may be most beneficial. Morning sessions in particular can help set your circadian rhythm and support energy levels throughout the day.
-
Quiet evening activities: If evening exercise is necessary, choose gentler activities like yoga or a light walk to promote relaxation.
By finding and sticking to an exercise routine that fits with your daily rhythm, you can not only improve your physical health, but also your sleep quality and mental well-being.

4. Thermal Therapies for Better Sleep
The Benefits of Sauna and Ice Bathing
Another important factor in my sleep hygiene has been incorporating ice bath and sauna routines. These thermal therapies have incredible benefits, not only for sleep quality, but also for easing the process of falling asleep. Personally, I like to do these routines 2-4 times a week. The contrast between heat and cold not only offers a unique physical experience, but also contributes to mental clarity and amazing health benefits. For those interested in diving deeper into how sauna and ice baths can maximize energy, mental clarity, read our article here about: Read more here about Heat Meets Cold: Explore the Secrets Behind Sauna and Ice Baths for Maximum Energy, Mental Clarity and Amazing Health Benefits.
These personal insights and tricks are fundamental to my own sleep practice and lay the foundation for a deeper understanding and exploration of sleep that we will explore in the following text. By acknowledging and adapting these strategies to our individual lives, we can all take steps toward a night filled with deeper and more rewarding sleep.
While most of us seek comfort and moderate temperatures for optimal relaxation, research shows that extreme thermal experiences, such as ice baths and saunas, can have remarkable effects on sleep quality. This chapter explores how these thermal therapies can manipulate the body's natural systems to promote deeper, more restorative sleep.
Thermal Therapies And Sleep
Thermal therapy refers to the use of heat or cold for health benefits. These methods have been used throughout history, but modern science is now beginning to understand how they can optimize sleep and overall well-being.
Sauna:
- Description: Sauna use involves short-term exposure to very high heat. Traditionally, saunas have been used for relaxation and detoxification.
- Effects on Sleep: Sauna use can increase the production of endorphins, the body's natural pain-relieving and happiness-promoting chemicals. The heat also increases body temperature, and the subsequent cooling after a sauna visit can signal to the body that it is time for sleep. Studies show that regular sauna use can improve sleep latency, duration, and quality.
- Recommendations: For best results, try a sauna session in the early evening hours. This gives your body time to cool down and prepare for sleep.
Ice bath:
- Description: Ice baths involve immersion in ice-cold water, which may seem counterintuitive for relaxation.
- Effects on Sleep: Cold exposure can drastically reduce body temperature, which helps regulate the body's natural sleep-wake cycle. Ice baths can also reduce inflammation, relieve muscle pain, and lower stress levels, all of which contribute to better sleep quality.
- Recommendations: A short ice bath can be effective when done a couple of hours before bed. This gives the body time to normalize its temperature and calm the mind.
The Science Behind Thermal Therapy and Sleep
Both sauna and ice bath can affect sleep through several biological mechanisms:
- Autonomic Nervous System Regulation: These therapies can help balance the sympathetic and parasympathetic nervous systems, which control the body's stress response and relaxation states.
- Hormonal Balance: Thermal therapy can affect levels of cortisol, adrenaline, and other hormones that affect sleep.
-
Circadian Rhythm Adjustment: By manipulating body temperature, you can help reset your body's internal clock, especially if you struggle with jet lag or irregular sleep habits.
Implementation in Daily Routine
To incorporate thermal therapies into your sleep-enhancing routine, start gradually and increase the intensity as your body adapts. It is important to consult with a healthcare professional, especially if you have underlying health conditions that may be affected by extreme temperatures.
Conclusion
Ice baths and saunas offer more than just physical and mental relaxation; they have the potential to transform your sleep quality. By integrating these practices into a well-considered health and wellness routine, you can experience improvements in both your sleep quality and overall quality of life.

5. Relaxation techniques
Breathing Exercises for Deep Relaxation
To promote relaxation and prepare the body for sleep, targeted breathing exercises combined with meditation are among the most effective techniques. These methods not only help reduce stress levels, but also lower the body's cortisol levels, a stress hormone that can disrupt sleep. Here are two breathing exercises and an introduction to how meditation can be integrated into your evening routine for better sleep:
4x4 Breathing Exercise
Also known as "box breathing," this technique involves breathing in through your nose for four seconds, holding your breath for four seconds, exhaling through your mouth for four seconds, and then holding your breath for four seconds before repeating the cycle. This method helps reduce stress levels and calm the mind, making it easier to fall asleep.
Deep Breathing With Extra Filling
Start by taking a deep breath through your nose, filling your lungs completely. Before you exhale, "top it up" with a little more air to really saturate your blood with oxygen. Then exhale completely through your mouth. Repeat this cycle 5-10 times. This exercise improves oxygen uptake and prepares your body for a night of restful sleep.
Meditation For Sleep
Integrating meditation into your evening routine can further enhance the effects of breathing exercises. Meditation, especially techniques focused on mindfulness or guided visualization, can help clear the mind and release mental tension that builds up throughout the day. Taking a few minutes to meditate after your breathing exercises can enhance your sense of calm and make the transition to sleep more seamless. For those new to meditation, it can be helpful to start with short, guided sessions that can be found in various apps or online.
My personal favorite is this youtube clip: 15 Minute Healing Meditation Music
By combining these breathing exercises with meditation, you can create a powerful evening routine (and morning routine as well) that promotes deep relaxation and prepares both body and mind for a night of undisturbed sleep. These techniques are not only helpful for improving sleep quality, but also for improving your overall well-being by reducing stress and anxiety.
6. Beverages And Stimulants
Replace Coffee and Energy Drinks With Green Tea
Although many of us rely on coffee and energy drinks to get us through the day, these stimulants can have a detrimental effect on the quality of our sleep. Research indicates that while caffeine can help you fall asleep quickly, the quality of your sleep is not as good. My own experience swapping coffee for green tea has been a revelation. For the first time in my life, I fell asleep within five minutes and woke up feeling genuinely refreshed.
Green tea contains about a quarter of the caffeine content of coffee and is rich in L-theanine, an active ingredient that interacts positively with caffeine to provide a more stable energy throughout the day, without the typical afternoon crash associated with coffee. The transition may require a 1-2 week adjustment period, and some may experience mild headaches at first, but the results – faster falling asleep and improved sleep quality – are well worth the effort.

Effects of Alcohol and Caffeine on Sleep Quality
Alcohol may induce sleep, but it disrupts REM sleep, which is critical for mental recovery and memory consolidation. Furthermore, alcohol increases cortisol levels, a stress hormone, making it more difficult to achieve deep, restorative sleep. Over time, even moderate alcohol consumption in the evening can disrupt the natural sleep architecture and reduce sleep quality.
Caffeine, known to block adenosine – a brain chemical that promotes sleep – has a half-life of about 5 hours, meaning that if you drink just one cup of coffee with about 100 mg of caffeine, you will have 50 mg of caffeine in your body after five hours, 25 mg after 10 hours, and so on. People with higher sensitivity to stimulants like caffeine may find that even a cup of coffee in the morning negatively affects their sleep quality. Caffeine is also found in tea, energy drinks, Pepsi, Coca Cola and some medications, and can elevate cortisol levels, making it harder to relax and fall asleep.
Risks of Sleeping Pills and Addiction
Although sleeping pills may seem like a quick fix for sleep problems, they carry the risk of addiction and can worsen sleep quality over time. Long-term use of sleeping pills, such as benzodiazepines and newer non-benzodiazepine sleep medications, can lead to tolerance (where higher doses are required to achieve the same effect) and dependence. There is often a frightening epidemic of overuse and addiction associated with these medications, often because they are prescribed without sufficient focus on addressing the underlying causes of sleep problems.
Long-Term Strategies for Better Sleep Hygiene
It is important to develop healthy sleep habits and address psychological issues such as anxiety or depression, which may be the true root of your sleep problems. This includes reinforcing good sleep hygiene practices, such as establishing a consistent bedtime and wake-up time, ensuring that your bedroom is optimal for sleep (cool, dark, and quiet), and avoiding electronic devices before bed. Regular, moderate exercise can also improve sleep quality, but should not be done right before bed as it can disrupt sleep by causing a surge in the hormone cortisol.
7. Optimizing Sleep Through Diet and Supplements
The Influence of Diet on Sleep
Diet is crucial for sleep quality and duration. Research shows that certain foods can either promote good sleep or disrupt it, depending on their content of specific nutrients. Of particular importance are melatonin and serotonin, hormones that regulate sleep cycles. Foods rich in tryptophan, an amino acid precursor to these hormones, can promote better sleep. In addition, high dietary fiber intake is associated with more restorative sleep, while foods high in sugar and saturated fat can disrupt sleep.
A balanced diet that includes a variety of nutrients supports not only overall health but also optimal sleep. Of particular importance is the impact of nutrients on neurotransmitters and hormones that regulate sleep cycles, including melatonin and serotonin. These substances help regulate our circadian rhythm and our sleep windows.
- Melatonin and Serotonin:
Melatonin, often called the "sleep hormone," regulates the sleep cycle, while serotonin, a hormone associated with feelings of well-being, is necessary for the production of melatonin. A number of foods containing tryptophan, an amino acid that is a precursor to both serotonin and melatonin, can therefore help promote sleep.
- Diet for Reduced Insulin Resistance and Better Sleep
Reducing sugar and processed carbs, increasing fiber intake from vegetables and whole grains, and including healthy fats and proteins to moderate blood sugar spikes and improve insulin response can help with more stable hormone balance and better sleep.
Foods That Promote Good Sleep
To improve sleep quality, consider including the following in your diet:
- Cherries: Naturally rich in melatonin, and can help regulate your sleep cycle.
- Complex Carbohydrates: Oatmeal has complex carbohydrates that can help promote increased serotonin production in the brain. Serotonin is known for its relaxing effects.
- Fatty Fish: Salmon, mackerel, and herring contain omega-3 fatty acids, vitamin D, and tryptophan, which has been shown to increase serotonin production.
- Nuts: Walnuts, almonds, and pistachios contain beneficial amounts of melatonin, as well as essential minerals like magnesium, which are known to promote relaxation and better sleep.
- Kiwi: Rich in antioxidants and tryptophan, studies suggest that eating kiwi before bed can improve both sleep quality and sleep duration.
- Bananas: Contain both magnesium and potassium, which act as muscle relaxants, as well as tryptophan, an amino acid that is converted into serotonin and then into melatonin in the body.
- Avocado: Rich in tryptophan, which helps produce serotonin and melatonin. Avocado is also a good source of magnesium and potassium, which help with muscle relaxation and can improve sleep quality.
- Herbal teas: Chamomile, lavender, and peppermint teas are known for their natural calming effects and can help end the day on a calm note.
Foods to Avoid Before Bedtime
Some foods and beverages can disrupt sleep, including:
- Caffeine: Avoid coffee, black/green tea, coca cola/pepsi and chocolate late in the day as caffeine can keep you awake and disrupt your sleep at night.
- Large meals and heavy foods: Eating large or heavy meals late at night can cause discomfort and disrupt sleep.
- Alcohol: Although it may seem like alcohol helps you fall asleep, it disrupts REM sleep, which is important for memory and learning.
- Sugary foods and refined carbohydrates: Can lead to restless sleep and frequent awakenings.
Recommended Supplements
Cod liver oil (Omega-3 Fatty Acids):
Omega-3 fatty acids, found in cod liver oil, are essential for brain health and have been linked to improvements in sleep quality, especially in children and young adults.
Melatonin:
As a natural sleep hormone, melatonin supplementation can help to adjust circadian rhythms, especially for those who struggle with jet lag or irregular sleep patterns. However, it is important to approach melatonin with a degree of skepticism, as excessive use can interfere with the body's natural production. And the duration of melatonin supplementation is not always sufficient. Recommend melatonin drops for faster action.
ZMA (Zinc, Magnesium Aspartate, and Vitamin B6):
ZMA (Zinc, Magnesium, Vitamin B6): ZMA is a combination of zinc, magnesium, and vitamin B6, known to improve sleep quality and promote deeper rest. Magnesium plays a particularly important role in promoting relaxation and reducing stress.
Recommended Use: Best taken on an empty stomach, approximately 30-60 minutes before bedtime. Avoid taking with calcium-rich foods or supplements, as calcium may inhibit the absorption of magnesium.
B vitamins:
B vitamins play a crucial role in the regulation of melatonin, a key hormone for sleep, and can therefore significantly improve sleep rhythms. Vitamin B6 in particular is known for its ability to promote a more regular sleep cycle by assisting in the production of melatonin. By ensuring a balanced intake of B vitamins, either through a well-adjusted diet or through supplementation, one can effectively support the body's natural sleep functions. This contributes not only to easier falling asleep, but also to a deeper and more restorative sleep.
NMN (Nicotinamide Mononucleotide) from Live Longer:
NMN (Nicotinamide Mononucleotide) from Live Longer represents an exciting breakthrough in anti-aging and wellness research, with potential benefits extending to sleep quality. By supporting cellular energy production through increased levels of NAD+ in the body, NMN may play a key role in maintaining and improving multiple aspects of health and wellness, including sleep.
Why It's Important
NAD+ (Nicotinamide Adenine Dinucleotide) is a critical cofactor in every cell in the body, playing a central role in energy metabolism and the maintenance of our overall health. As we age, natural production of NAD+ declines, which can lead to reduced cellular function and energy levels. NMN acts as a precursor to NAD+, and supplementation with NMN can therefore help increase levels of this important molecule, supporting cellular energy production, and thus counteracting certain effects of aging.
Benefits
- Improved Energy Levels: By supporting the cells' ability to produce energy, NMN can contribute to increased vitality and stamina, which is essential for tackling the challenges of the day and promoting good sleep at night.
- Delayed Aging Process: NMN may help delay the aging process by supporting DNA repair and maintaining healthy cell function, which may have a positive effect on sleep quality.
- Strengthened Immune System: Good sleep is essential for a strong immune system. By contributing to overall vitality and health, NMN can indirectly support the immune system and thus contribute to better sleep. Optimal dosage may vary based on individual needs and goals. What is NMN? Benefits, uses and everything you need to know!
Specialized Herbs for Sleep
Using herbs such as ashwagandha, passion flower, chamomile, lavender, and valerian root may promote sleep by increasing GABA levels in the brain or contributing to relaxation.
Additional Strategies for Better Sleep
- Mouth tape: For those who struggle to breathe through their nose at night, mouth tape can promote nasal breathing and improve sleep quality.
- Oil-based Nasal Spray: An oil-based nasal spray can help keep the nasal passages moist, support nasal breathing and thus contribute to a more undisturbed sleep.
By integrating these supplements and complementary strategies into your daily routine, you may experience a noticeable improvement in both sleep quality and overall well-being. Remember, it's always best to consult with a healthcare professional before starting any new supplements, especially if you're already taking medications or have existing health challenges.
With these essential tips, combined with carefully selected supplements, you are well on your way to deeper and more rewarding sleep.
8. How Fasting Can Improve Sleep
Intermittent Fasting
Fasting, or intermittent fasting, has become increasingly popular as a method for improving health and well-being. While most people focus on fasting’s effects on weight loss and metabolic health, there is also fascinating evidence to suggest that fasting can have significant benefits for sleep quality, particularly through mechanisms such as cell renewal and enhancing the body’s natural regenerative processes. This article explores how fasting, especially more intensive forms of intermittent fasting, can contribute to better sleep.
Fasting And Cell Renewal
One of the most notable effects of fasting is its ability to promote autophagy, a process by which cells break down and remove defective proteins and components. This is essential for cell renewal and maintenance of healthy cells. During sleep, the body undergoes natural repair and regeneration processes, and by enhancing autophagy through fasting, one can potentially enhance these processes, leading to more efficient recovery and improved sleep quality.
Intermittent Fasting and Hormonal Balance
Intermittent fasting may also affect sleep by regulating hormones critical to the sleep-wake cycle. Fasting has been shown to affect levels of leptin and ghrelin, hormones that signal satiety and hunger, respectively. By modifying the secretion of these hormones, fasting may help stabilize energy levels and improve circadian rhythms, making it easier to maintain a healthy sleep schedule.
Fasting and Reducing Inflammation
Chronic inflammation has been linked to a number of health problems, including sleep disorders. Fasting can reduce inflammation in the body, which not only contributes to overall health, but can also improve sleep quality. By reducing inflammation, fasting can help reduce the incidence of sleep disorders related to pain and discomfort, thus promoting more undisturbed rest.
Practical Tips For Fasting And Sleep Improvement
- Start Gradually: If you're new to fasting, start with milder forms before exploring longer periods of fasting. This can help your body adapt without too much stress.
- Choose Your Fasting Period Wisely: To maximize the benefits of fasting before sleep, consider ending your fast a few hours before bedtime. This can help ensure that hunger doesn't interfere with your ability to fall asleep.
- Focus on Nutritious Foods: When you are not fasting, be sure to consume a balanced diet rich in nutrients that support both overall health and sleep quality.
- Listen to Your Body: Monitor how fasting affects your sleep and adjust your approach as necessary. If you experience negative effects, you may want to consult with a healthcare professional.
Conclusion
Fasting, especially intermittent fasting, offers a unique approach to improving sleep quality through mechanisms such as cell renewal, hormonal balance, and reduction of inflammation. By integrating fasting in a thoughtful and balanced way into your lifestyle, you can experience improvements not only in your sleep, but also in your overall health and well-being.

9. How to Reduce Cortisol Levels in the Body for Better Sleep Quality
For a period of my life, I struggled to maintain a good night's sleep. I would often wake up at 3am, tense and unable to fall back asleep. I eventually realized that this was likely due to a build-up of stress over time, which was causing me to have an abnormal cortisol cycle. It became necessary for me to make significant lifestyle changes to manage the situation.
Abnormal Cortisol Cycle

In a healthy curve, cortisol is high in the morning and then gradually declines throughout the day. But when we are chronically stressed, our bodies release cortisol at all times, and the curve becomes a roller coaster.
Quick Techniques To Promote Falling Asleep
- Breathing techniques: Deep, calm breathing can calm the mind and prepare the body for sleep. Specific breathing techniques, described in Chapter 6, can be particularly effective.
- Meditation: Regular meditation practice can reduce evening cortisol levels and promote deeper, more restorative sleep.
- Mindset changes: Changing how you respond to stress can significantly reduce cortisol levels. This is explored in more detail in Chapter 1.
- The benefits of morning light: Exposure to bright morning light, whether from natural sunlight or wake-up lights, has been shown to increase cortisol levels in the morning by as much as 50%. This supports alertness and helps lower cortisol levels later in the evening, which is optimal for good sleep.
- Cortisol and sleep: Studies show that healthy individuals and those with insomnia exhibit similar cortisol levels throughout the day, but they differ markedly around bedtime. People with insomnia experience an increase in cortisol levels when they should be at their lowest, which can interfere with sleep. Proper management of cortisol through exposure to light and darkness can help regulate these levels.
- Strategies to reduce evening light: Using dimmer, red or orange lights in the evening is recommended to minimize light-induced disruption of circadian rhythms. It is also beneficial to minimize the time spent looking directly at bright light sources, such as cell phones, at night, and instead use them indirectly or at low brightness.
- Implementing lighting strategies: It is important to be aware of the power of light both in the morning and evening. Bright light in the morning and limited light exposure before bed are key strategies to strengthen the body's natural rhythms and improve sleep quality.
Long-term changes for lower cortisol levels.
- Adjust daily routines: When sleep problems arise, it may be beneficial to make some changes to your daily routine. This may include:
- Take a relaxing vacation or a cabin trip: Spending time in natural, calm surroundings can help the body reset stress levels.
- Visits to spas and wellness facilities: Regular visits to spas, saunas or even ice baths, as discussed in Chapter 5, can reduce physical and mental stress.
- Regular walks in nature: Establishing the habit of taking walks in the woods can be an effective way to lower daily stress and cortisol.
- Dietary changes: Temporarily cutting out stimulants like caffeine and alcohol may be beneficial, especially during periods of high stress. A dietary change to include foods rich in magnesium and omega-3 fatty acids may also help reduce cortisol levels.
- As mentioned in the section above, morning routines to bring in light, as well as evening routines to reduce light: Establishing these routines, morning light for 10-15 minutes within the first 2 hours of waking at the latest, as well as dimming the lights at least an hour before bedtime can help the body prepare for sleep and establish and maintain the correct cycle of cortisol and malathion hormones in the body.
These changes have helped me manage and ultimately significantly improve my sleep quality. By implementing both quick and long-term techniques, one can effectively reduce cortisol levels and promote better health and well-being.
10. Evening Routines For Better Sleep
Evening is a critical time to prepare both your body and mind for a restorative night’s sleep. Effective evening routines can be the key to unlocking deeper, more rejuvenating sleep. This chapter explores how you can establish a relaxing and effective evening routine that sets the stage for optimal sleep.
The Importance of a Consistent Evening Routine
A consistent evening routine helps regulate your body's internal clock, or circadian rhythm, which tells your body when it's time for sleep. By repeating the same actions every night, you can signal to your body that the time to relax and prepare for sleep is approaching.
Steps to Create Your Optimal Evening Routine

That’s why it’s important to adapt and experiment with different techniques to find what works best for you. Remember, every small improvement in your sleep quality is a step in the right direction. Remember that restoration and growth occur during the deepest stages of sleep.
By prioritizing and improving sleep, we also improve our overall health and well-being. Sleep is the foundation for a healthy body and a clear mind, and by prioritizing good sleep, we take an important step towards a richer, longer and more energetic life. Mastering sleep is a superpower that gives us all a better life.
If there is interest in exploring this topic more deeply, I look forward to possibly diving into a Part 2 based on your feedback and interest. This will drive the series forward and hopefully enrich our understanding even more.
