A circadian rhythm that is misaligned often feels like constant friction. Common signs include feeling alert late at night but tired during the day, energy crashes, difficulty falling asleep despite fatigue, and needing weekends to recover from the week. Circadian disruption can be subtle, but timing mismatches between light, food, movement, and sleep can significantly affect how you feel and function.

You fix your circadian rhythm by consistently placing key signals like light, food, and activity at the right times of day. Morning light, stable wake times, earlier meals, and a protected evening are the highest-leverage changes. It is not about doing more, but about timing what you already do.
