Hot Yoga is also known as Bikram Yoga in Sanskrit. Ideally, the room was heated to 40°C  with a humidity of 40%.  A vigorous yoga session at this temperature promotes profuse sweating which believe will help you to lose weight, get rids the body of toxins and also makes the body very warm and therefore more flexible.   But sad to say, my facial skin can’t afford to loose all it’s moisture as they get hydrated very fast.  No amount of serum moisturizer can help unless I go for treatment like oxyen mask or microdermabrasion.  I would say, Hot Yoga is not for everyone especially if you have problematic skin like me.
