Night Waking

Waking up at 3am, after a few hours, or several times a night for no clear reason is one of the most common sleep complaints there is, and it usually traces back to one of a small number of causes.

Sometimes it’s stress or a racing mind. Sometimes it’s a physical trigger like blood sugar, alcohol, or a full bladder. Once you know which pattern matches your own waking, the fix gets a lot more specific than generic sleep hygiene advice.
