Why do I get dizzy in the shower?
Last updated September 3, 2026.
Hot water widens blood vessels near the skin, your pressure dips, and standing still lets blood pool in your legs - so less reaches your brain. Dehydration makes it worse. MedlinePlus names sudden blood pressure drops and dehydration as classic dizziness causes. Usually the fix is cooler, shorter showers and water first.

What to do
- Cool it down and shorten it: less heat means less vessel widening.
- Drink water before showering, especially in the morning or after exercise.
- Feeling faint? Sit down immediately - riding it out seated beats a fall.
- Recurring with no clear cause, or with ringing ears or spinning? See a GP.
