For the past 6 weeks, I had everyday adventure with my dearest friend in India in which the weather is so hot and very humid. We were always walking to visit friends and some of her client. It was so easy to get dehydrated. I always had a big bottle of water every day. As it is said to keep fatigue at bay, drink four to six 8-ounce glasses of filtered water a day. Drink even more if you’re exercising strenuously or sweating.
