How to Prevent Heat StrokeMost reports of death caused by heat focus on children and the elderly, because they’re more vulnerable to overheating. But healthy adults can fall prey to heat, too, sometimes because we feel immune to damaging effects of heat, or possibly because more of us are so used to an air-conditioned environment that we don’t take the dangers of overheating seriously, suggests a study published a few years ago in the journal Environmental Health Perspectives. The next time you expect to spend a significant amount of time in outdoor heat, take some or all of these important items with you. Also bring along some common sense, and listen when it tells you to get inside or under some shade trees.

7 Essential Items for Spending Time in the Summer Heat

1. Thermometer
There’s a difference between life-threatening heatstroke and milder heat illnesses that don’t require a visit to the emergency room, says Tony Scarzo, MD, emergency medicine physician at St. Louis University School of Medicine. “To really have heatstroke, you have to have a body temperature of 106 degrees F,” he says. He adds that heatstroke is generally accompanied by some kind of neurological dysfunction, such as hallucinations, agitation, confusion, or other type of altered thinking process, and it requires immediate medical attention. In the absence of those alarming symptoms, take your temperature if you’re overwhelmed by heat. Heat exhaustion, which is the condition that precedes heatstroke, comes with heavy sweating, rapid breathing, and a fast, weak pulse. If you or a friend is suffering from heatstroke, get to a hospital or call for emergency assistance. Until help is available, do what it takes to bring the person’s body temp below 101 degrees (see below for ideas).

2. Water bottles or water packs
To avoid heatstroke and other heat illnesses, the best thing you can do is drink lots of water, says Dr. Scarzo. The standard recommendation of 64 ounces per day is good to follow, he says, but if you’re exercising or exerting yourself in the heat, you may need more. And take water breaks. “If you’re working out longer than an hour, drinking 8 ounces of water very hour is quite reasonable,” he says, adding that water-pouch backpacks are perfect for summertime workouts. You can fill them with ice, he says, which keeps you cool and gradually melts so you have plenty of water to keep you hydrated. Also avoid caffeine before going out in the heat, he says. It acts as a diuretic and dehydrates you.

3. Your cellphone
“I always recommend that people work out with a friend or someone that can recognize symptoms of heatstroke,” says Dr. Scarzo. When your friends aren’t available for company, keep your cellphone attached to your hip in case you collapse.
