 [ Symptoms ] i have shingles and was with my daughter who just found out she is pregnant is there a danger to the fetus [ Disease ] there is really not much point in washing your face before exercise you need to cleanse your skin after exercising and sweating in order to make sure you do not develop blocked pores or possible fungal infections of the skin interestingly it is equally important to thoroughly dry your skin after exercising fungal infections such as  jock itch  can arise if the skin stays damp so be sure to towel off thoroughly and perhaps apply powder if you can not get completely dry ps women can get jock itch  too hope this helps
