During the hot Summer months it is especially important to keep our self hydrated. Humidity and heat can cause our bodies to rapidly loose water. Also its worth to mention when a person is sick (vomiting, fever, etc.) they are loosing fluids rapidly therefore an increase of fluids is needed (a little more than water in this case will work wonders things like Gatorade or Powerade will help replenish the electrolytes lost).
Two simple tips to know you are well hydrated:
1. Drink enough so you don't feel thirsty
2. Drink enough so your urine is always clear
Why is water so good? Well that will next weeks posts! ;)
