The upcoming Fourth of July holiday is usually grounds for lounging in the sun, hanging out with friends and family and enjoying a good barbecue. However, when the heat rises it’s important to protect yourself from heat and sun related illnesses such as heat stroke.
William Roberts, M.D., professor in the Medical School’s Department of Family Medicine and Community Health says heat stroke is a rise in the core body temperature to a level, usually greater than 104º-106º. This causes organs to lose function and fail and can also affect the brain.
“Another term for heat stroke is heat encephalopathy. Once the outside temperature rises above 94 degrees, especially if there is high humidity, it is difficult for the body to get rid of the heat made by the body processes. The risk goes up with exercise,” said Roberts.
Heat stroke is dangerous and can lead to hospitalization and even death. Symptoms of heat stroke can sneak up on you so it is important to listen to what your body is telling you on extremely hot days.
“Stop your activities if you feel ill, do not take on heavy exercise if you are not used to the heat, make sure to take rest breaks, and drink fluids when thirsty,” said Roberts.
Some common symptoms of heat stroke are:
-
Clumsiness
-
Stumbling
-
Headache
-
Nausea
-
Dizziness
-
Apathy
-
Confusion
-
Impairment of consciousness
Although it is imperative to listen to what your own body is telling you, it is important to be aware of how others are feeling as well, paying particular attention to kids and the elderly.
“Very young children need close watching and should be moved to air conditioned or shady spaces if they get flushed red skin or they do not act normal. Most kids will modify activity appropriately as long as no adults are pushing them to do more,” said Roberts. “The biggest risk to kids is likely sunburn and precautions should be taken to reduce the burning ray exposure. In addition to kids, elderly citizens have an increased risk.”
Some tips Roberts recommends when going into the holiday weekend festivities are:
-
Use sunscreen and wear a broad brimmed hat.
-
Stay hydrated and drink when thirsty.
-
Limit alcohol consumptions to two drinks per day, and do not “bank” them
