that's a very interesting question and i'm glad you asked! being a perioperative nurse i've informed many patients on how to care for themselves when they get home. one piece of advice i usually give is this: don't jump into a hot shower right away. why? because it can cause a quick shift of your body fluids into your legs. if that happens it can cause your blood pressure to drop which can result in lightheadedness or even fainting. even if you haven't had surgery this fluid shift can occur from taking hot showers. you can test this theory yourself by seeing if you feel faint after taking a cooler shower. if not problem solved! meanwhile remember: safety first! if you've been feeling lightheaded after showering you need to make sure to use a shower stool or grab bars to keep yourself from falling. whenever you feel lightheaded (whether in the shower or not) your best bet is to sit down as quickly as possible. sitting down is better than falling down! if your symptoms persist you should consult a health care professional for a physical exam. wishing you well!
why do i faint or nearly faint after taking a shower?
