How bright light exposure affects cortisol levels | Satchin Panda
Cortisol, a steroid hormone that participates in the body’s stress response, is produced in humans by the adrenal gland. Several factors influence its release, including stress. Exposure to bright light also promotes the release of cortisol, and, in turn, the hormone drives wakefulness during the daytime hours. Chronic stress and mis-timed exposure to light can dysregulate cortisol release and promote aging, however. In this clip, Dr. Rhonda Patrick describes how bright light exposure drives cortisol release.
