Generally, submerging your head in hot water is a bad idea—especially somewhere communal.

Water between 102 and 104 degrees Fahrenheit breeds bacteria, a reason why hot tubs require sanitation. Thankfully, bathing your legs or torso in the water does not fully expose you to these potential bacteria.

However, your nose, eyes, ears and mouth give easy ingress to your body, meaning you are more likely to catch an illness or infection with your head underwater.

Hot tubs relax the body and ease everyday aches and pains. For this reason, many athletes own spas or frequent them on rest days. Although your hot tub might tempt you into a brief soak after a workout, doing so may do more harm than good.
