Waking at night
5 questions
Is it normal to wake up during the night?
Why do I wake up around 3 AM?
The second half of the night holds lighter sleep and longer REM periods, so it’s easier to surface.[4] Caffeine, alcohol, evening light, schedule changes, stress, menopause and health conditions can all play a part.[1][18] Read the full explainer.
When should I talk to a clinician about waking at night?
Does alcohol help you sleep?
It can speed falling asleep, but it tends to add disruption to the second half of the night.[15]
How late is too late for caffeine?
It differs between people. In one small trial, a large dose still disrupted sleep when taken six hours before bed.[13] Recording the time of your last cup is a simple way to see your own pattern.
Cortisol
3 questions
Does waking at 3 AM mean my cortisol is high?
Is adrenal fatigue real?
Can poor sleep affect cortisol?
In a lab study of healthy young men, a night of partial or total sleep loss was followed by higher cortisol the next evening.[12] It was a small study, so it shows a direction rather than a rule. More on cortisol and sleep.

What is the 7-Day Rhythm Field Guide?
A free, printable 14-page PDF with one tracking page per day, a weekly summary and questions to bring to a clinician. See inside.
Do I have to give my email to get it?
Yes. The guides open with a free email signup, which also adds you to the UNWIRE™ letter. The two sleep calculators need no email.
Will the guide improve my sleep?
We can’t promise that, and the guide doesn’t try to. It gives you a clearer record of your own routines and observations, which is useful to look at yourself or bring to a clinician.
