Your Body Has a Clock. Is Yours Running on Schedule?
Ever feel wide awake at midnight but exhausted at 7 a.m.?
Your internal body clock — your circadian rhythm — helps regulate when you're naturally sleepy and when you're alert.
When that internal clock doesn't line up with the schedule you're expected to follow, you may be dealing with a circadian rhythm sleep-wake disorder.
It can affect:
🌙 When you fall asleep
☀️ When you wake up
💼 Your ability to function during the day
😴 How rested you feel
Shift workers, frequent travelers and people with naturally delayed sleep schedules may be particularly familiar with this struggle.
Sometimes the problem isn't that you can't sleep.
It's that your body's clock and your schedule aren't agreeing.
