As parts of the country are expected to swelter under triple digit temperatures, health officials warn the public, saying it’s important to heed the heat. Although hot days are normal for the summer, this week’s record-breaking heat can be traced to a dome of high pressure located in the upper atmosphere, blanketing the Northeast, Ohio Valley, and the Great Lakes, according to The Weather Channel.

Under that bubble of high pressure, temperatures usually rise 10 degrees above the average. To help with this, doctors and public health officials have cautioned everyone to take the heat into consideration to avoid heat exhaustion and dehydration. Here are a few doctor’s tips to help survive a heat wave and help keep your cool.

“Alcohol and caffeine are dangerous in this type of weather. They create a chemical inside your body that makes you pee more than you should–it’s a diuretic,” says Dr. Salvatore Pardo. Dr. Pardo is the vice chairperson of the emergency department at Long Island Jewish Medical Center in New Hyde Park, New York.
