Why Lying Down Makes You Sleepy, According to Huberman

The Surprising Reason Why Lying Down Makes You Sleepy

Walker explains that lying down horizontally makes us sleepy due to the body’s ability to distribute blood and decrease core body temperature more effectively in this position. When warm blood is pushed from the core to the surface areas of the body, heat is released, causing the core body temperature to drop. This drop in core body temperature increases the likelihood of sleepiness, as it is difficult to fall asleep without this decrease. The body’s superior ability to distribute blood and dissipate heat when lying down is likely the reason humans evolved to sleep in this position.
