Itchy rashes, bug bites and sunburn can put a damper on summer fun. Summer rashes range from mild to severe, and last from a few days to a few weeks. Most of these are easily treated at home or in an immediate care center or clinic, but if left untreated, you could be at risk for something more serious.
The best way to handle a rash is by preventing it in the first place. That’s not always possible, so here are the top summer rashes and what to do about them.
“There are different kinds of summer rash, but they all have similar symptoms of redness, itching, blisters or bumps,” said Mary Rademaker, Mary Rademaker, M.D., medical director for Norton Immediate Care Centers. “Rashes such as these are common in the summer as temperatures climb, people get active outdoors more and humidity rises.”
Poison ivy
Poison ivy, and its siblings poison oak and poison sumac, are caused by an oily substance on the leaves that triggers allergic reactions. Poison ivy is the most common. Poison sumac is considered one of the most toxic plants in the country, but it is relatively rare. You get a poison ivy rash by brushing up against the leaves or by touching something that has brushed against the leaves, such as pet fur.
Rashes from poison ivy and the like can range from mild to severe. In lighter-skinned people, the rash will appear red. Itching, swelling and small blisters are also symptoms. It may be more difficult to see redness on darker-skinned people.
Heat rash
Also called prickly heat, this condition occurs in hot, humid weather. The rash might look like very small red bumps or one large lump that feels prickly or itchy. It is caused by folds of skin rubbing together such as in the armpits, elbow creases or under the breasts.
“When blocked pores trap sweat under the skin, a rash can happen,” Dr. Rademaker said.
Physical activity in a warm environment, tight or restrictive clothing, and bandages on the skin can contribute to heat rash.

Sunburn
Most people are familiar with this one — damage caused to the skin by exposure to the sun’s ultraviolet rays. Sunburn appears within a few hours of sun exposure. In fair-skinned people, it can be easier to see pink or red patches. In darker skin, it can be harder to see. Sunburned skin feels hot and painful to the touch. Depending on the severity of the burn, there can be swelling or blistering. In very severe cases, you may feel nauseated or dizzy, or have a headache. Sunburn can occur year-round on any exposed area of skin, but is most common on the neck, shoulders, face, head and ears.
Sun rash
Not to be confused with the above sunburn, sun rash is a sensitivity to ultraviolet (UV) light. While a sunburn tends to be more uniformly pink or red, sun rash is blotchy and bumpy, and typically very itchy.
Bug bites in summer
Besides rashes, you may encounter insect bites and tick bites. Sometimes insect bites can become very swollen, itchy or painful. Ticks like grassy and wooded areas, but they can live in yards and neighborhoods. If a bull’s-eye-like rash develops around the tick bite, you may have the beginning stages of Lyme disease.
Sun-related rashes are easily preventable.
“It’s extremely important to wear a broad-spectrum sunscreen,” Rachel said.
Quality sunscreen offers protection from both ultraviolet A and ultraviolent B rays.
“Besides sunburn and sun rash, sunscreen prevents premature aging and reduces skin cancer risk,” Rachel said.
Other ways to protect your skin from the sun include:
Since heat rash is caused by high levels of moisture trapped near the skin, it’s wise to wear loose-fitting clothing made of light fabrics such as cotton. Some other ways to prevent heat rash include limiting outdoor activities to early morning or evenings, and showering regularly, especially after strenuous outdoor activity.
Most summer rashes are annoying but treatable at home. You can alleviate most symptoms by:
“If your symptoms don’t seem to get better within a few days, it might be time to visit a health care professional,” Dr. Rademaker said.
