Doctors generally and municipal, state and federal health officials usually issue a list of ” don’ts” to guide you through the h ot summer months. They tell you what to eat and what not to eat, how much water to drink and when to drink it, what to wear and what not to wear. Following these “don’ts” no doubt makes it easier for you to withstand the heat. The doctors who issue these “don’ts” do so only after a long study of the effects of the heat on you. They know what they are talking about.
