Hormones play a central role in shaping how the body feels and functions from morning to night. From the moment a person wakes up to the time they fall asleep, hormones like cortisol and melatonin follow a predictable pattern tied to the circadian rhythm.
These natural fluctuations influence alertness, focus, and even the familiar experience of daily energy slumps. Understanding how hormones shift across the day can help explain why energy rises and falls, and what can be done to stay balanced.
