A prolonged heat wave has continued throughout the Coachella Valley during the summer months. What is a heat wave? A heat wave is a period of abnormally hot weather generally lasting more than two days. Heat waves can occur with or without high humidity. They have potential to cover a large area, exposing a high number of people to hazardous heat. Heat can be very taxing on the body; check out the heat related illnesses that can occur.
Stay Informed: Monitor local radio and television (including NOAA Weather Radio), internet and social media for information and updates.
How to Stay Safe During Excessive Heat Events
Outdoor Activities
- Slow down. Reduce, eliminate or reschedule strenuous activities until the coolest time of the day. Those particularly vulnerable to heat such as children, infants, older adults (especially those who have preexisting diseases, take certain medications, living alone or with limited mobility), those with chronic medical conditions, and pregnant women should stay in the coolest available place, not necessarily indoors.
- Dress for summer. Wear lightweight, loose fitting, light-colored clothing to reflect heat and sunlight.
- Minimize direct exposure to the sun. Sunburn reduces your body’s ability to dissipate heat.
Eating and Drinking
- Eat light, cool, easy-to-digest foods such as fruit or salads. If you pack food, put it in a cooler or carry an ice pack. Don’t leave it sitting in the sun. Meats and dairy products can spoil quickly in hot weather.
- Drink plenty of water (not very cold), non-alcoholic and decaffeinated fluids, even if you don’t feel thirsty. If you are on a fluid-restrictive diet or have a problem with fluid retention, consult a physician before increasing consumption of fluids.
- Do not take salt tablets unless specified by a physician.
Cooling Down
- Use air conditioners or spend time in air-conditioned locations such as malls and libraries.
- Use portable electric fans to exhaust hot air from rooms or draw in cooler air.
- Do not direct the flow of portable electric fans toward yourself when room temperature is hotter than 90°F. The dry blowing air will dehydrate you faster, endangering your health.
- Take a cool bath or shower.
Check on Others
- Check on older, sick, or frail people who may need help responding to the heat. Each year, dozens of children and untold numbers of pets left in parked vehicles die from hyperthermia. Keep your children, disabled adults, and pets safe during tumultuous heat waves.
- Don’t leave valuable electronic equipment, such as cell phones and gps units, sitting in hot cars.
- Make sure rooms are well vented if you are using volatile chemicals.

Safety Tips for Parents and Caregivers
Children and Heat Vulnerability (Source: The Impacts Of Climate Change On Human Health In The United States: A Scientific Assessment)
- Newborns, infants, and young children are particularly vulnerable to heat-related illness and death. Their bodies are less able to adapt to heat than are adults.
- Children under four years of age experience higher hospital admissions for respiratory illnesses during heat waves.
- The effects are more severe on children because their bodies warm at a faster rate than adults.
Protect and prepare: Keep children cool by having them drink plenty of water, take lots of breaks, wear light-colored and lightweight clothing, and limit playing outdoors to cooler times of the day. Make sure fluids are not very cold or high in sugar/sweetener content.
Heat Safety in Vehicles
Even on mild days in the 70s, studies have shown that the temperature inside a parked vehicle can rapidly rise to a dangerous level for children, pets and even adults. Leaving the windows slightly open does not significantly decrease the heating rate. A dark dashboard or car seat can quickly reach temperatures in the range of 180°F to over 200°F. These objects heat the adjacent air by conduction and convection and also give off long wave radiation, which then heats the air trapped inside a vehicle.

- Touch a child’s safety seat and safety belt before using it to ensure it’s not too hot before securing a child
- Never leave a child unattended in a vehicle, even with the windows down, even for just a minute
- Teach children not to play in, on, or around cars. They could accidentally trap themselves in a hot vehicle.
- Always lock car doors and trunks–even at home–and keep keys out of children’s reach.
- Always make sure children have left the car when you reach your destination. Don’t leave sleeping infants in the car.
Heat Safety for Outdoor Workers
Outdoor workers can be at a higher risk to the effects of excessive heat. The Wet Bulb Globe Temperature (WBGT) is a good measure of heat stress during outdoor activities; learn more here. See Occupational Safety and Health Administration (OSHA) resources and recommended practices when working under hot conditions.
- Drink water often
- Rest and cool down in the shade during breaks
- Gradually increase workload and allow more frequent breaks for new workers or workers who have been away for a week or more
- Know symptoms, prevention, and emergency response to prevent heat-related illness and death
- Check weather forecasts ahead of time to be better prepared.
