Understanding Coffee and Cortisol

The video explains how our internal biological clock, the circadian rhythm, regulates cortisol, a hormone linked to alertness. Cortisol peaks between 8-9 a.m., noon-1 p.m., and 5:30-6:30 p.m. Consuming caffeine during these times reduces its effectiveness and increases tolerance. It's best to drink coffee after these peaks, ideally an hour after waking, regardless of the time. The video also invites viewers to ask questions and subscribe for more science content.
