What’s circadian rhythm and what’s it have to do with cortisol?Updated a year ago

Your circadian rhythm is a part of your body’s internal clock, running behind the scenes as a 24-hour cycle. This cycle is fundamental in carrying out the essential processes and functions that keep us alive. One of the most vital circadian rhythms is the sleep-wake cycle – and cortisol makes is its master. The rise and fall of cortisol is critical in helping you fall asleep by your target bedtime, stay asleep through the night, wake up in the morning, and feel good overall by keeping hormone levels balanced. When your cortisol levels are imbalanced, it can create sleep issues and hormonal imbalances – or in other words, keep you up at night and feeling drained during the day.
