The Power of Our Internal Body Clock
06:55 - 18:00 (11:04)
Our body has a master circadian clock which aligns 24-hour oscillations in gene expression and synchronizes all the internal clocks in our body to a general temperature rhythm to maintain a regular schedule for sleep and wake cycle. Temperature is one of the powerful ways our body communicates with different systems of the body.

The 24-hour circadian rhythm is controlled by two mechanisms - adenosine accumulation, which makes you sleepy, and a temperature oscillation that takes 24 hours, which determines how awake or sleepy you feel, and it is aligned to the 24-hour spin of the Earth on its axis.

The 24-hour circadian rhythm is controlled by two mechanisms - adenosine accumulation, which makes you sleepy, and a temperature oscillation that takes 24 hours, which determines how awake or sleepy you feel, and it is aligned to the 24-hour spin of the Earth on its axis.

Every cell in our body has a 24-hour rhythm dictated by genes, but it's the master circadian clock above the roof of the mouth that synchronizes all the clocks of the body.

Summary
Every cell in our body has a 24-hour rhythm dictated by genes, but it's the master circadian clock above the roof of the mouth that synchronizes all the clocks of the body. Being diurnal is far better for our immune and metabolic function than being nocturnal, regardless of sleeping habits.

Temperature is a powerful way of communication between different systems in the body.
13:53 - 17:19 (03:25)
Summary
Temperature is a powerful way of communication between different systems in the body. Recent research suggests that the master circadian clock may secrete a peptide to lock receptors and get the temperature just right, which could determine the optimal temperature for sleep.
