5 Common Summer Rashes and How to Prevent Them

All forms of heat rash usually develop on parts of the body where skin folds over itself, like the underarms, groin, neck, abdomen and under the breasts. Infants typically get heat rash on the neck, shoulders and chest. Tight clothing can also make it more likely for one to develop heat rash.

Newborns, who have less-developed sweat ducts that can easily become blocked and more rolls of skin, are more susceptible to heat rash than older kids and adults, Dr. Katta said, “especially if you’re bundling them up tightly when it’s hot out.”

Heart disease prevention includes controlling risk factors like diet, exercise, and stress. Heart disease symptoms in women may differ from men. Use a heart disease risk calculator to determine your heart attack risk.

Electrolytes are substances that become ions in solution and acquire the capacity to conduct electricity. The balance of the electrolytes in our bodies is essential for normal function of our cells and our organs. Common electrolytes include sodium, potassium, chloride, and bicarbonate. The functions and normal range values for these electrolytes are important, and if an electrolyte is at an extreme low or high, it can be fatal.

Dehydration is the excessive loss of body water. There are a number of causes of dehydration including heat exposure, prolonged vigorous exercise, and some diseases of the gastrointestinal tract.

There are no tests for heat rash. Your doctor can diagnose it just by looking at it. But most cases don’t need to be seen by a doctor. They go away by themselves. If your rash doesn’t go away after 3 or 4 days, or if it seems to be getting worse, call your doctor. In some cases, the rash may be caused by an infection.

The body can adapt very well to hot weather, but it takes time to acclimate. The actual temperature is just one factor when a person decides to work, play, or exercise in the heat. The heat index adds humidity to the equation since sweat cannot evaporate if the water content in the air (humidity) is high. If the air holds as much water as it can there is no place for sweat to go, and evaporation cannot cool the body.

Dizziness is a symptom that often applies to a variety of sensations including lightheadedness and vertigo. Causes of dizziness include low blood pressure, heart problems, anemia, dehydration, and other medical conditions. Treatment of dizziness depends on the cause.

The skin’s job is to protect the inside of the body from the outside world. It acts as a preventive barrier against intruders that cause infection, chemicals, or ultraviolet light from invading or damaging the body. It also plays an important role in the body’s temperature control. One way the body cools itself is by sweating and allowing that sweat or perspiration to evaporate. Sweat is manufactured in sweat glands that line the entire body (except for a few small spots like fingernails, toenails, and the ear canal).

Another condition often mistaken for heat rash is polymorphous light eruption, which is an itching or burning rash of tiny, inflamed bumps or slightly raised patches of skin. “It’s a very unique condition that people notice when they take a sunny vacation,” for the first time in a while.

This can cause them to “break out in a rash, usually pretty exclusively on the sun exposed areas.”
