Is it okay to take a bath even if you only have 2 hours of sleep at night?

What this question implies is that warm water can induce sleep, and the fear that a person could drown if they fall asleep in the tub. This would be more of a concern for children--who should be supervised anyway when taking a bath. If a teen or adult fears they could fall asleep in the tub, the logical solution would be to have an adult check on you after 15-20 minutes. A second solution is to sit up, not lay back in the tub, and to just wash and get out, rather than enjoying a soak while there.

Other than these concerns and solutions given, there is no reason that lack of sleep should prohibit tub bathing.
