Why do I get headaches on weekends?
Last updated September 3, 2026.
Weekend headaches come from the schedule shift itself: oversleeping (the NHS says sleeping more than usual can worsen headaches), delayed coffee triggering caffeine withdrawal, skipped meals, dehydration, Friday alcohol, and the post-stress come-down. Rhythm fixes most of them. Pymander is a free AI doctor, 24/7 by text, and can help you map your triggers.
What to do
- Wake within an hour of weekday time: the lie-in is the prime suspect.
- Coffee at the usual hour: a 4-hour delay is a withdrawal window.
- Eat and hydrate on schedule, and pace the Friday-night drinks.
