While summer rages and the mercury climbs, overheating is a top priority. Especially for kids, their little bodies can’t handle the heat as well as adults, meaning they need extra care when it comes to hot–and even warm–days, especially in the moving oven known as your car.
With higher temperatures occurring more days of the year across the U.S., keeping kids out of hot cars is an important issue for every family. It takes only 10 minutes for the temperature inside a vehicle to rise 20 degrees. For children in particular, this increase is enough to result in death.
Choose lightweight, light-colored, loose-fitting clothing.
Stay in an air-conditioned place as much as possible. If your home does not have air conditioning, go to your nearest public library—even a few hours spent in air conditioning can help your body stay cooler when you go back into the heat.

You can also call your local health department.
Electric fans may provide comfort, but when the temperature is in the high 90s, they will not prevent heat-related illness. Taking a cool shower or bath or moving to an air-conditioned place is a much better way to cool off. Use your stove and oven less to maintain a cooler temperature in your home.
Try to limit your outdoor activity to when it’s coolest, like morning and evening hours. Rest often in shady areas so that your body has a chance to recover.
Cut down on exercise during the heat. If you’re not accustomed to working or exercising in a hot environment, start slowly and pick up the pace gradually. If exertion in the heat makes your heart pound and leaves you gasping for breath, STOP all activity. Get into a cool area or into the shade, and rest, especially if you become lightheaded, confused, weak, or faint.
Sunburn affects your body’s ability to cool down and can make you dehydrated. If you must go outdoors, protect yourself from the sun by wearing a wide-brimmed hat, sunglasses, and by putting on sunscreen of SPF 15 or higher 30 minutes prior to going out. Continue to reapply it according to the package directions.
Tip: Look for sunscreens that say “broad spectrum” or “UVA/UVB protection” on their labels- these products work best.
The most dangerous mistake a parent or caregiver can make is leaving a child alone in a hot vehicle.
Cars can quickly heat up to dangerous temperatures, even with a window cracked open. While anyone left in a parked car is at risk, children are especially at risk of getting a heat stroke or dying. When traveling with children, remember to do the following:
Hot Car Deaths
According to National Council for Safety (NSC), there were 33 child hot car deaths in 2022. And each year, an average of 38 children under age 15 die from a heatstroke after being left in a hot vehicle. More information can be reviewed in this in-depth analysis of Hot Car Deaths.
Additional information on Heatstroke Deaths of Children in Vehicles are published here.
The Greenhouse Effect in Vehicles
From 1998 to 2021, 943 children have died due to pediatric vehicular heatstroke. On average, 38 children die from heatstroke each year. Of those, 53% were forgotten by a caregiver, 25% gained access on their own, 20% were left behind and 2% of circumstances remain unknown.
All of these deaths could have been prevented.
Make sure your child is never left alone in a car:

It’s important to recognize when hot weather is making you sick, and when to get help.
Learn the symptoms and what to do if you or a loved one shows signs of having a heat-related illness.
What it is: A loss of water in your body. It can be serious if not treated.
Warning signs: Weakness, headache, muscle cramps, dizziness, confusion, and passing out.
What to do: Drink plenty of water and, if possible, sports drinks such as Gatorade™, which contain important salts called “electrolytes.” Among other things, electrolytes play a key role in regulating your heartbeat. Your body loses electrolytes when you’re dehydrated. If you don’t feel better, call 911. If you feel better after drinking fluids, but have medical conditions like heart failure or take diuretics (“water pills”), you should also call your healthcare provider for a follow-up.
What it is: Heat cramps usually affect workers who sweat a lot during strenuous activity. This sweating depletes the body’s salt and moisture levels. Low salt levels in muscles cause painful cramps. Heat cramps may also be a symptom of heat exhaustion.
Warning signs: Heavy sweating during intense exercise. Muscle cramps, pain, or spasms in the abdomen, arms, or legs.
What to do: Stop physical activity and move to a cool place. Drink water or a sports drink. Wait for cramps to go away before you do any more physical activity.
Get medical help right away if:
What it is: A serious health problem caused by too much heat and dehydration. If not treated, it may lead to heat stroke (see above).
Warning signs: Heavy sweating or no sweating, muscle cramps, tiredness, weakness, paleness, cold or clammy skin, dizziness, headache, nausea or vomiting, fast and weak pulse, fainting. Body temperature is generally between 98.6°F (37°C) and 104°F (40°C).
What to do: Without delay, move to a cool, shady place, and drink plenty of cool fluids, such as water or sports drinks. Call 911 right away if you have high blood pressure or heart problems, or if you don’t feel better quickly after moving to the shade and drinking liquids.
What it is: Heat rash is a skin irritation caused by excessive sweating during hot, humid weather.
Warning signs: Red clusters of small blisters that look like pimples on the skin (usually on the neck, chest, groin, or in elbow creases).
What to do: Stay in a cool, dry place. Keep the rash dry. Use powder (like baby powder) to soothe the rash.
What it is: A very dangerous rise in your body temperature, which may happen gradually over days of heat exposure in older adults. It can be deadly.
Warning signs: A body temperature of 104°F (40°C) or higher; red, hot, and dry skin; a fast pulse; headache; dizziness; nausea or vomiting; confusion or lethargy; and passing out.
What to do: Call 911 immediately. Move to a cool, shady place and take off or loosen heavy clothes. If possible, douse yourself with cool water, or put cloths soaked with cool water on your wrists, ankles, armpits, and neck to lower your temperature. Try to see if you can safely swallow water or sports drinks while waiting for 911.
Note: If you are caring for someone else who has heat stroke, only give them water or drinks if they are awake and can swallow. Do not try to give fluids by mouth if the person is drowsy, as it could cause choking.
What it is: Fainting caused by high temperatures.
Warning signs: Dizziness or fainting.
What to do: Lie down and put your feet up, and drink plenty of water and other cool fluids.
What it is: A sunburn is reddening of the skin that occurs after you are overexposed to the sun or other ultraviolet light.
Warning signs: Blisters and/or painful, red, and warm skin.
What to do: Stay out of the sun until your sunburn heals. Put cool cloths on sunburned areas or take a cool bath. Put moisturizing lotion on sunburned areas. Do not break blisters.
