Understanding Circadian Rhythm

Circadian rhythm refers to the natural internal clock that regulates sleep-wake cycles and other bodily functions over a 24-hour cycle. It tends to run a bit longer than 24 hours, closer to 25, and without daily resets, it will gradually drift. Light plays a crucial role in this resetting process as it travels through the optic nerve to the suprachiasmatic nucleus in the brain, controlling hormone release such as melatonin for sleep and cortisol for wakefulness. Understanding and optimizing this rhythm is vital for maintaining energy levels, performance, and overall well-being.
