Title: Could a person sitting in a bath dehydrate?
Post by: thedoc on 10/09/2013 12:35:10

If one went without consuming water for three or four days but was submerged in fresh water for all that time, would you still dehydrate?

thanks,
Ahmed

If it is a hot water, you can sweat while in water.
No significant amount of water from the bath would enter your body through the skin.
You obligatory lose some water by breathing and by urinating (at least about half a liter of urine per day even if you do not drink), so you would lose at least about 2 liters of water in three days, which means mild to moderate dehydration.

The question was whether it is possible to become dehydrated while submerged in water, so the short answer is 'yes', Ginny.  Despite being submerged in water, your body would lose water that could not be replaced by absorption.
