Optimizing sleep involves getting bright light exposure in the morning and dimming lights in the evening to regulate sleep hormones and promote a natural sleep-wake cycle.
Certain supplements like magnesium, apigenin, and theanine can improve sleep quality by promoting relaxation through the activation of GABA neurotransmitters.
Short naps and non-sleep deep rest sessions can enhance neuroplasticity, learning, and alleviate symptoms of depression when timed strategically.
Going to bed earlier can improve sleep quality and overall well-being, as each hour of sleep before midnight has a deeper restorative effect than those after midnight.

The Impact of Light Exposure on Sleep
Light exposure, particularly bright light from sunlight, plays a crucial role in regulating sleep and wakefulness. The neurons in the back of the eye are activated by bright light, sending signals to the brain's hypothalamus, which controls sleep, hormones, immune function, appetite, and mood. To optimize sleep, it is recommended to get bright light exposure, ideally from sunlight, in the morning for about 5-20 minutes. If sunlight is not available, bright artificial lights can be used. In the evening, it is advised to dim lights to promote the natural decrease in body temperature and melatonin release, which helps induce sleep.
Supplements and Behaviors for Better Sleep
Certain supplements like magnesium (magnesium 3 and 8 or magnesium bisglycinate), apigenin (a derivative of chamomile), and theanine can help improve the depth and quality of sleep. These supplements promote the activation of GABA, a neurotransmitter that enhances relaxation. It is important to consult with a doctor before taking any supplements. In addition to supplements, adopting behavior modifications can enhance sleep quality. Behaviors like limiting caffeine intake, avoiding screens before bed, practicing relaxation techniques such as non-sleep deep rest (NSDR) or reverie, and maintaining a cool bedroom temperature can improve sleep.
Nap Benefits and Managing Depression
Short naps (less than 90 minutes) and non-sleep deep rest (NSDR) sessions, also known as progressive relaxation techniques, can enhance neuroplasticity and learning. Naps are most effective when taken within four to six hours after intense learning activities. Depression can be influenced by factors such as physical activity, temperature regulation, and sleep. Engaging in appropriate physical exercise, especially zone 2 cardio and resistance exercise, promotes better sleep and overall mental health. In some cases, adjusting sleep schedules, going to bed earlier, and managing environmental factors like light exposure and temperature can help alleviate symptoms of depression.
The power of going to bed earlier
Going to bed a little earlier can have a powerful effect on sleep quality and overall well-being. Every hour of sleep before midnight is believed to have a deeper restorative effect than those after midnight. By going to bed earlier, one can wake up feeling refreshed and energized, allowing for greater focus and productivity in the early morning hours.
The impact of alcohol on sleep
Consuming alcohol too close to bedtime can negatively impact sleep quality. Alcohol dehydrates the body and disrupts the normal functioning of neurons, which is essential for a good night's sleep. Hydrating with electrolytes and avoiding strong sedatives in combination with alcohol can help improve sleep quality and reduce hangovers.
The relationship between caffeine and sleep
Caffeine, as a stimulant, affects our sleep-wake cycle. While it can increase alertness and wakefulness, it can also disrupt sleep if consumed too late in the day. Tapering off caffeine in the afternoon and considering intermittent caffeine usage can help prevent sleep disturbances while still enjoying the benefits of increased motivation and focus.
Building impulse control and resilience
Developing impulse control and resilience are vital aspects of mental performance. By engaging in practices such as cyclic hyperventilation or cold water exposure, individuals can increase their stress threshold and better manage triggers. Cultivating mental toughness through self-directed practices can lead to greater self-improvement and a more resilient mindset.
Leading neuroscientist and Stanford University School of Medicine professor Dr. Andrew Huberman goes in-depth on how small behaviors can make a huge impact on your health. Dr. Huberman offers essential insights into how light affects your sleep and your energy levels, which supplements actually work, tips to control bad impulses, exercises to slow the aging process, and so much more.
Dr. Huberman has made numerous significant contributions to the fields of brain development, brain function and neural plasticity, which is the ability of our nervous system to rewire and learn new behaviors, skills and cognitive functioning. Huberman is a McKnight Foundation and Pew Foundation Fellow and was awarded the Cogan Award in 2017, given to the scientist making the most significant discoveries in the study of vision. His lab’s most recent work focuses on the influence of vision and respiration on human performance and brain states, such as fear and courage.
