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.
As temperatures hit dangerously hot conditions in Florida, here are some tips to stay safe:
Extreme heat can be dangerous for anyone, but hot weather can be especially dangerous for those with chronic medical conditions. If you or someone you know has a chronic medical condition, follow the information below to help keep you, or the person in your care, safe.
Stay in Touch
Visit adults at risk at least twice a day and closely watch them for signs of heat exhaustion or heat stroke. Infants and young children, of course, need much more frequent watching.
- They may be less likely to sense and respond to changes in temperature.
- They may be taking medications that can make the effect of extreme heat worse.
- Conditions like heart disease, mental illness, poor blood circulation, and obesity* are risk factors for heat-related illness.
Stay Cool
Wear Appropriate Clothing: Choose lightweight, light-colored, loose-fitting clothing.
Stay Cool Indoors: Stay in an air-conditioned place as much as possible. If your home does not have air conditioning, go to the shopping mall or public library—even a few hours spent in air conditioning can help your body stay cooler when you go back into the heat. Call your local health department to see if there are any heat-relief shelters in your area.
- Keep in mind: 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.
Schedule Outdoor Activities Carefully: 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.
Roughly 40% of unwanted heat buildup in our homes is through windows. Use awnings or curtains to keep the heat out! #BeatTheHeat
Pace Yourself: 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.
Wear Sunscreen: 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.
Do Not Leave Children in Cars: 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:
- Never leave infants, children or pets in a parked car, even if the windows are cracked open.
- To remind yourself that a child is in the car, keep a stuffed animal in the car seat. When the child is buckled in, place the stuffed animal in the front with the driver.
- When leaving your car, check to be sure everyone is out of the car. Do not overlook any children who have fallen asleep in the car.
Avoid Hot and Heavy Meals: They add heat to your body!
Stay Hydrated
Drink Plenty of Fluids: Drink more fluids, regardless of how active you are. Don’t wait until you’re thirsty to drink.
- Warning: If your doctor limits the amount you drink or has you on water pills, ask how much you should drink while the weather is hot.
- Stay away from very sugary or alcoholic drinks—these actually cause you to lose more body fluid. Also avoid very cold drinks, because they can cause stomach cramps.
Replace Salt and Minerals: Heavy sweating removes salt and minerals from the body that need to be replaced. A sports drink can replace the salt and minerals you lose in sweat.
- If you are on a low-salt diet, have diabetes, high blood pressure, or other chronic conditions, talk with your doctor before drinking a sports beverage or taking salt tablets.
Keep Your Pets Hydrated: Provide plenty of fresh water for your pets, and leave the water in a shady area.
Stay Informed
Check for Updates: Check your local news for extreme heat alerts and safety tips and to learn about any cooling shelters in your area.
Know the Signs: Learn the signs and symptoms of heat-related illnesses and how to treat them.
Use a Buddy System: When working in the heat, monitor the condition of your co-workers and have someone do the same for you. Heat-induced illness can cause a person to become confused or lose consciousness. If you are 65 years of age or older, have a friend or relative call to check on you twice a day during a heat wave. If you know someone in this age group, check on them at least twice a day.
Tracking the Heat: The CDC Heat & Health Tracker provides local heat and health information so communities can better prepare for and respond to extreme heat events.
