  • 00:05:00 Sleep and wakefulness are determined by two forces: a chemical force (adenosine) and a behavioral force (how long you've been awake). Adenosine creates a sleep drive or hunger, and caffeine is an adenosine antagonist, which means it blocks the sleepiness signal. However, each person metabolizes caffeine differently, so it is important to figure out what works for you in terms of caffeine consumption and sleep.

He advises that if you can watch the sunrise, great, that's perfect for triggering activation of these cells, however, if you wake up a few hours after the sunrise, you still wanna get outside and view sunlight.

  • 00:35:00 The Huberman Lab Podcast discusses the importance of light exposure early in the day for setting the body's internal clock. The circadian rhythm is key for proper sleep and overall health, and light is the primary zeitgeber for setting this rhythm. Other factors that can influence the circadian rhythm include timing of food intake, exercise, and drug use.
  • 00:40:00 The Huberman Lab podcast discusses how to get better sleep and be more alert when awake. The main way to set the body's internal clock is by exposure to light, especially sunlight. Additionally, exercising early in the day and viewing the sunset can help protect against the negative effects of light later in the day.
