JACKSON, Miss. ( WJTV ) – As extreme heat advisories begin taking effect for the summer months of 2024, doctors at the University of Mississippi Medical Center (UMMC) said it’s important to take proactive measures to protect yourself and others.

Extreme heat often results in the highest number of deaths among all weather-related disasters each year.

In extremely humid areas like Mississippi, it’s especially important to pay attention to the heat index, which describes what temperatures feel like to the human body. High humidity levels increase the heat index by reducing the body’s ability to cool itself through sweating, making it feel hotter than the actual air temperature.

Heat-related illnesses, such as heat exhaustion and heat stroke, can occur when the body is unable to cool itself adequately and can cause permanent damage if not promptly treated.

“Number one: make sure you have access to clean drinking water,” said Carl Mangum, associate professor of nursing and emergency preparedness and response specialist. “Also, make sure you have access to some type of cooling, whether that’sa fan or air conditioning. If your home is not air conditioned and the temperature gets to well over 100 degrees, especially if the heat index is in the 110s, consider a plan to go to a family member or friend’s home.”

Try to stay inside if possible. Don’t plan to do things like cut grass at noon.

“If you’re doing anything outside, it needs to be either very early in the morning or late in the evening if you have to do it,” Mangum said. “If it’s not a must, it’s best just to wait until things cool back off again.”

If you are working outside during extreme heat conditions, take precautions to stay safe and avoid heat-related injuries or illnesses.

• Wear light, loose-fitted clothing: This will help keep you cool by allowing better air circulation and aiding in the evaporation of sweat.
• Seek shaded areas or wear a wide-brimmed hat to protect your face from the sun.
• Take regular breaks: Avoid over-exerting yourself by taking intermittent breaks in the shade, preferably in an air-conditioned space.
• Drink plenty of fluids: When you are dehydrated, your body retains more heat. Staying hydrated helps your body sweat.
• Avoid strenuous activity: If it’s necessary, try to complete fatiguing tasks in the early morning or evening to avoid the peak heat of the day.
• Avoid alcoholic and caffeinated beverages: Alcohol and caffeine are diuretics, which increase the loss of fluids from your body.
• Do not leave people or pets in a closed car: According to the National Safety Council, 37 children on average under the age of 15 die each year from heatstroke after being left in a vehicle each year.
