Beat the Heat Through Hydration

To beat the heat in the middle of an ongoing worldwide heat wave, the first rule is to stay hydrated. Drinking two to four glasses of water every hour is recommended when facing temps in the 90s and 100s, because the human body needs to keep sweating to stay cool. Eat small meals made up of mostly fruits and vegetables, The New York Times advises; proteins and salty foods cause increases in internal metabolic temperatures. Also avoid alcoholic beverages and coffee to feel cooler, since both can cause temporary increases in blood pressure and body temperature.
