Dr. Matthew Walker, All Things Sleep — How to Improve Sleep, How Sleep Ties Into Alzheimer’s Disease and Weight Gain, and How Medications (Ambien, Trazodone, etc.), Caffeine, THC/CBD, Psychedelics, Exercise, Smart Drugs, Fasting, and More Affect Sleep (#650) – The Blog of Author Tim Ferriss | Free Podcast Summary

A recent study demonstrated that rocking beds and hammocks at a frequency that matches slow brain waves can help increase deep and non-REM sleep, and potentially improve learning and memory.

• Make good sleep a priority by avoiding caffeine and light exposure in the evening, avoiding screens, and having consistent timing. Consult a healthcare professional for medication help.
• Understanding and controlling the factors affecting deep sleep can result in a better night’s rest.
• Exercise and caffeine can both help you get better-quality sleep, but it’s important to be aware of the timing and dosage of your caffeine intake.

• Caffeine can increase anxiety, reduce deep non-REM sleep, and have a long half-life, making it important to be mindful of our caffeine intake.
• 2-3 cups of coffee per day, with lighter roasts and finer grinds, can help maximize the beneficial antioxidants and polyphenols.
• Be mindful of what substances you consume and their quantity to ensure their effects on sleep are beneficial.

• THC can benefit sleep, but it is important to be mindful of dosage, as too much can lead to negative withdrawal effects and disrupt REM sleep.
• CBD may increase deep non-REM sleep, while THC can reduce REM sleep and cause more vivid dreams when stopped. It is important to be mindful of the dosage when using these substances for sleep.
• Clinical studies are exploring potential benefits of CBD, such as reducing anxiety and helping with sleep, while mitigating risks and improving outcomes.

• Recent studies suggest that classical psychedelics may interfere with sleep quality, reduce the need for sleep, and improve sleep quality when taken alongside physical exercise and THC.
• Psychedelics and dream sleep both provide mental health benefits, but they do so in different ways, potentially inhibiting the ability to sleep.
• Poor sleep can lead to an increase in hunger and food intake, which could lead to weight gain. Get the rest you need to stay healthy.

• Getting enough restful sleep and eating a balanced diet can help us maintain good health and avoid an increased risk of obesity.
• Sleep deprivation can lead to excessive eating and an increase of up to 600 extra calories, which is the body’s response to a perceived state of starvation. Taking control of our sleep is essential for our health.
• Supplementing electrolytes and fructose-rich fruits can help maintain blood pressure, melatonin levels, and sleep quality during fasting.

• Cognitive behavioral therapy is the recommended first-line treatment for insomnia and is safer and more effective than drugs in the long term.
• Trazodone can help reduce the time it takes to fall asleep and increase deep non-REM sleep without affecting REM sleep, providing a more naturalistic way to help with sleep and improving learning and memory.
• Trazodone can be an effective tool to improve sleep quality, but it is important to cycle the medication and be aware of potential risks.

• Sleep is an essential part of life and has been for as long as life has existed on Earth.
• Evidence suggests that sleep plays a vital role in maintaining the health of all major physiological systems in the body and plays a key role in the functioning of the brain.
• It appears to be a common theme across all species, from mammals to birds, reptiles, fish, and even bacteria.
• There is still much to learn about the purpose of sleep and its evolutionary history.

• Learning from this section is that self-tracking can often be useful in formulating hypotheses to be tested in scientific studies.
• Gathering data from a large group of individuals, such as an N of a thousand people, can be helpful in understanding trends and drawing conclusions, even if the data is not scientific.
• Additionally, it was mentioned that rocking, or having a rocking motion, can improve sleep quality and duration.
• This can be seen in the way parents rock babies to help them fall asleep.

• Sleep deprivation can have a serious impact on our health, including our metabolism.
• Excessive eating is a common symptom of sleep deprivation.
• This may be a compensatory mechanism to try to fix the lack of sleep, as our body may interpret this as a form of starvation.
• In fact, research has shown that when we are deprived of sleep, we may consume up to three to six hundred extra calories, even if we are not expending more energy.
• So it is not necessarily because we are trying to make up for the energy that we are burning due to a lack of sleep.
• Rather, this is our body’s response to a perceived state of starvation.

Medications can help bring you back into a natural balance, not take you away from it.
