When summer temperatures climb, so does the risk of serious heat-related illnesses like heat cramps, exhaustion, and heat stroke — especially in kids. Knowing the signs and taking a few key precautions can make a big difference in staying safe during hot weather.

Seattle Children’s Hospital offers expert guidance on how to prevent heat stroke and recognize symptoms early. Below, we’ve outlined their best safety tips, plus quick ways to cool down if your child gets overheated. Once you’ve covered your health bases, check out our list of fun, family-friendly ways to beat the heat around Puget Sound — from splash pads to shady wading pools and indoor escapes.

How to void heat cramps, exhaustion, and stroke

Seattle Children’s Hospital offers this list of expert tips on how to prevent heat exhaustion and heat stroke, helping keep kids safe during hot summer weather:

  • Drink more water. When working or exercising in hot weather, have your child drink large amounts of cool water. This helps to prevent dehydration. For teens, this means at least 8 ounces (240 mL) every 15 to 30 minutes. Water is the ideal liquid for replacing lost sweat. Very little salt is lost.
  • Sports drinks. If kids are working out for longer than an hour, replace 1 water drink per hour with a sports drink.
  • Take water breaks. Do this every 15 minutes in the shade. Drink some water even if you’re not thirsty.
  • Avoid salt tablets. They slow down stomach emptying and delay the absorption of fluids.
  • Dress cool. Wear a single layer of lightweight clothing. Change it if it becomes wet with sweat. Protect babies with fevers from heatstroke by not bundling them in blankets. Also, do not dress them in too many clothes. Children usually need the same number of clothing layers as adults.
  • Exercise smart. Physical activity in hot weather should be increased slowly. Sports coaches suggest that exercise sessions be shortened and made easier when it’s hot. This is usually when the temperature is over 82°F (28°C). Also, this is very important if the humidity is high.
  • Spend as much time as possible inside with air-conditioning. Electric fans also help.
  • Limit hot tub time. When using a hot tub, limit use to 15 minutes. Use a “buddy” system in case a heat reaction suddenly occurs. Do not use a hot tub if your child has a fever. Also, do not use them right after hard work or sports. The body needs to get rid of heat. NOTE: children less than 3 years old should not use hot tubs.
  • Never leave a child or a pet in a parked car. The temperature inside a car can increase 20 degrees in just 10 minutes and 40 degrees in an hour. It doesn’t have to feel hot outside to be dangerous inside a car.

Ways to cool down quickly if you get too hot

Sometimes, no matter how well you follow the advice on how to prevent heat exhaustion and heat stroke, a child can still get overheated. The following tips apply whether your child just needs a cool off.

  • Give your child a lukewarm bath or sponge them down with lukewarm water.
  • Apply cold water or ice to strategic points on the body where the veins are close to the surface — such as the wrists, neck, chest, and temples. It can quickly lower the temperature
  • Have your child rest in a cool, dark room with a fan. You can place bowl ice in front of the fan to cool the room further.

If anyone in your family is experiencing these symptoms call 911 or get them to a hospital immediately. Use icepacks as outlined above while you transport to the hospital or wait for emergency workers to arrive. Heat stroke is a severe medical emergency.
