WHAT DOES THE PINEAL GLAND DO?
The pineal gland acts as the body’s light meter. It receives light information from the eyes and
then sends out hormonal messages to the body. This tiny gland transmits information to the body
about the length of daylight, commonly called circadian rhythm.
The pineal gland tells every other part of your body whether it’s light or dark out, what season
you’re in, and whether days are getting longer or shorter.
Unlike most of our brain, the blood-brain barrier doesn’t isolate the pineal gland from the rest of
our body. Instead, the pineal gland l gets a tremendous amount of blood flow, second only to the
kidneys. Surrounded by and immersed in cerebrospinal fluid, this gland camps out in a tiny cave-
like area behind and above the pituitary gland.
