More than 50 million people will experience dangerous temperatures this week as a late August heat wave hits the Midwest, Mid-Atlantic and Southeast regions of the country.
Temperatures will go as high as 100 degrees, breaking records in some areas. The combination of high temperatures and humidity and little relief in the overnight hours will add up to a higher risk of heat-related illness.
During hot weather, people might become ill and it’s critical to act fast. Heat illness can be prevented. Learn the warning signs and how to help so you can react quickly.
Heat can make anyone ill, but older adults, the very young, pregnant women and those with chronic medical conditions are more at risk. People who work outdoors, have limited personal resources and live in places that lack green spaces are also at higher risk.
Heat cramps are an early sign of trouble and include heavy sweating with muscle pains or spasms. To help, move the person to a cooler place and encourage them to drink water. Get medical help if symptoms last longer than an hour or if the person has heart problems.
Heat exhaustion is a more severe condition signaled by cool, pale and clammy skin; a fast or weak pulse; nausea or vomiting; tiredness or weakness; or a headache, dizziness or passing out. To help, move the person to a cooler place, loosen tight clothing, encourage them to sip water slowly. Use wet cloths, misting or fanning to help cool them off. Get medical help right away if symptoms get worse or last longer than an hour, or if the person begins vomiting or acting confused.
Heat stroke is a deadly condition that requires immediate medical help. Symptoms include a high body temperature; hot, red, dry or damp skin; a fast or strong pulse; a headache or dizziness; or nausea, confusion and passing out. Call 911 right away if you think someone may have heat stroke. Then move the person to a cool place, and use wet cloths, misting or fanning to help cool them off. Do not give the person anything to drink.
CLIMATE CRISIS A FACTOR The number of people exposed to extreme heat is growing exponentially due to climate change in all world regions, according to the World Health Organization (WHO). Heat stress is a leading cause of weather-related deaths and can exacerbate underlying illnesses including cardiovascular disease, diabetes, mental health and asthma. Heatstroke is a medical emergency with a high-case fatality rate. Heat-related mortality for people over 65 years of age increased by approximately 85% between 2000–2004 and 2017–2021.
WHAT YOU SHOULD DO The American Red Cross recommends taking three steps to stay safe in extreme heat: slow down, stay hydrated and spend time indoors.
Slow down by postponing or limiting outdoor activities. If you must work outdoors, take frequent breaks and avoid the hottest part of the day. Never leave children or pets in your vehicle alone.
Stay hydrated by drinking plenty of water and avoiding sugary, caffeinated and alcoholic drinks. Check that animals also have access to fresh water and shade.
Spend time indoors in an air-conditioned place. If you don’t have air conditioning, go to a public library, shopping mall or public cooling center. Check on loved ones and neighbors who may be at risk and don’t have air conditioning.
