This podcast episode interviews neuroscientist Dr. Andrew Huberman about optimizing sleep and wakefulness. The conversation covers the impact of light exposure on sleep cycles (morning sunlight or bright artificial light is crucial, dim light in the evening is beneficial), supplement recommendations for sleep (magnesium threonate/bisglycinate, apigenin, theanine), and the importance of regulating body temperature for better sleep. Dr. Huberman also discusses strategies for improving impulse control through daily "no-go" exercises and techniques for managing stress, such as controlled breathing exercises. Listeners gain practical advice on improving sleep quality and overall well-being through behavioral changes and supplemental strategies.
