What is Extreme Heat?
Definition and Characteristics of Extreme Heat Conditions
Extreme heat is a weather event with very high temperatures. These temps are hotter and more humid than usual for that place and time. High humidity makes the air feel heavy, and the heat more intense. This mix of heat and humidity stops the body from cooling down effectively, leading to a rapid increase in body temperature.
More people die from extreme heat than any other weather in the U.S. This situation is getting worse because of climate change. As the planet heats up, extreme heat events are becoming more severe and common. This poses a big risk to our health and safety.
“An average person needs to drink about 3/4 of a gallon of water daily to prevent heat illness. At least one gallon of drinking water per person per day should be set aside during emergencies.”
When the National Weather Service sees temperatures and humidity getting dangerous, they issue warnings. A heat advisory comes when the heat index is expected to be between 100 and 104 degrees Fahrenheit. If the heat index is set to go over 105 degrees for two days or more, an excessive heat warning is given.
Extreme heat can cause serious health issues, including heat-related illnesses and deaths. Knowing what extreme heat is and being prepared is key to staying safe during these weather events.
Dangers of Extreme Heat
Health Effects and Risks of Heat-Related Illnesses
Extreme heat can be very dangerous to your health. It can cause problems like heat exhaustion or heat stroke. In the worst cases, it can even lead to death.
When it’s really hot, our bodies try to cool down. But sometimes, they can’t do it fast enough. This makes our body temperature rise too high. Things like high humidity, being too heavy, not drinking enough, some medicines, and health issues can make things worse. They might hurt our brain and other important parts of the body. It’s crucial to act fast if you or someone else shows signs of too much heat.
As people get older, they might have a harder time dealing with extreme heat. For example, what might be just heat cramps in a 17-year-old, could be much more serious for a 40-year-old. If you’re over 60, it could even lead to a life-threatening condition. Older people, little kids, those who are sick all the time, as well as those who take certain medications or use drugs are at more risk. This is especially true when the weather is much hotter than usual.
Heat stroke is a very serious emergency. If your body temperature goes over 106°F, you need to get help right away. In big cities, especially during a heatwave, the air can trap bad stuff like pollution. This makes the heat even more dangerous.
A lot of people died in St. Louis in 1966 because of heat. Most of these deaths happened in very crowded parts of the city with bad air and high temperatures.
Drinking alcohol in hot weather is a bad idea. It doesn’t help your body manage the heat. Cool air from an air conditioner is a very good way to stay safe from the heat. Even a short break in a cool place every day can help a lot.
Wearing the right kind of clothes can keep you cooler in hot weather. It’s best to wear clothes that are light in color and weight. This helps reflect the heat away from your body. Also, drink lots of water. Even if you don’t feel thirsty, you need to drink enough to keep cool.
If you’re likely to get sick from the heat, it’s best to avoid hard work in the sun. The summer heat can be really dangerous. It causes more deaths in the U.S. than any other weather. Too much heat can even make the power go out. This is because many people will be using their air conditioners a lot. Bad air from the heat can also be very risky, especially for those with heart or lung problems, older people, and little kids. It’s important to take care and stay cool when it gets really hot.
Who is at Increased Risk?
During extreme heat, some people face a greater threat. This includes older adults aged 65 and over, young children under 2, and those with chronic health conditions or mental illness. Older adults and those with disabilities who need help are especially at risk.
Even those who are young and healthy might suffer in hot weather. If they do strenuous outdoor activities, their risk increases. The danger is real, with an 85% higher heat-related death rate for people over 65 from 2000-2021. Plus, nearly half a million heat-related deaths happen worldwide every year, mostly in Asia and Europe.
Groups like these are hit hardest by extreme heat. In the summer of 2022, over 61,000 heat-related deaths happened in Europe alone. In 2003, a high-acuity heatwave caused 70,000 deaths in Europe. And in a Russian 44-day heatwave in 2010, there were 56,000 extra deaths.
Heat’s impact depends on various factors. Age, health, and where you live matter a lot. Poor living conditions and no cooling make things worse for the urban and rural poor. Jobs that keep you outside, like for workers, athletes, and civil protection employees, also increase the risk. They expose people to exertional heat stress.
| High-Risk Group | Factors Contributing to Increased Vulnerability |
