Occasional or mild vaginal sweating is not uncommon. The condition usually goes away within a few weeks, but if the sweat becomes more noticeable, you should see your doctor to rule out other serious health conditions.
How can I prevent it from happening again?
If you have had this problem in the past and it has been brought on by puberty or pregnancy, there are no known prevention measures that will stop it occurring again. However, if you have any problems with excessive sweating when going to bed at night then avoid sleeping directly after exercising during hot weather as this could cause perspiration in the vagina.
Is there anything else I need to know about vaginal sweating?
If a woman sweats profusely from her vagina regularly she may develop an infection called bacterial vaginosis (BV). If BV is diagnosed early enough it can be treated with antibiotics such as metronidazole which reduces discomfort and helps eliminate bacteria responsible for causing the condition. If left untreated BV increases risk of developing sexually transmitted infections including human papillomavirus (HPV) which causes cervical cancer among others .
