US heat wave: Extreme heat poses serious risks to our bodies – here’s how to protect

US heat wave: Summer’s dog days have arrived, bringing with them sometimes-unbearably hot temperatures. Once again, this year is expected to be the hottest on record. Already, a great deal of the country, from coast to coast, is experiencing “extremely dangerous heat.”

The National Weather Service reports that dangerously hot regions in the central and eastern US are expected to expand, while the West has been experiencing record-breaking temperatures that are predicted to remain high. Over two dozen people have died in the US this past week due to this recent bout of intense heat.

The US government defines extreme heat as “a period of high heat and humidity with temperatures above 90 degrees for at least two to three days.” Extreme heat is the leading cause of weather-related deaths each year.

Older adults, children, individuals with illnesses, and those who are overweight are the groups most vulnerable to extreme heat.

What physical effects does heat have on us?

Our bodies ideally run at 98.6 degrees Fahrenheit. Our bodies must expend more energy to maintain a given temperature when the outside temperature rises. Several medical problems are related to sudden heat waves.

Heat stroke is the most typical. A temperature measurement higher than 98.6 can be used to determine this. Dizziness and a lack of sweating despite red skin are among the symptoms. It is advised that you take the patient to the hospital. Heat exhaustion and cramping are two more related conditions that can be lethal.

How to maintain your composure

Keep cool this summer with these recommendations from ready.gov:

• On a hot day, never leave people or pets in a closed car.
• Go to a cooling center if you don’t have air conditioning.
• Take a cool shower or bath.
• Make sure your clothes are loose, lightweight, and light-colored.
• Reduce your home’s temperature by using your oven less.
• Find some shade if you’re outside. Make sure your hat is wide enough to protect your face.
• Stay hydrated by drinking plenty of water.
• Try to avoid high-energy activities or working outdoors during midday heat.
• Make sure your family, neighbors, and seniors are okay.
• Keep an eye out for heat cramps, heat exhaustion, and heat stroke.
• Make sure your pet is safe. Make sure they have plenty of cool water and comfortable shade if they’re outside. Your pet’s feet can get very hot on asphalt and dark pavement.

As it’s the airflow that makes you feel cooler, not the temperature reduction, fans aren’t recommended for cooling.
