Heat rash, also known as prickly heat or miliaria, is developed when sweat pores are blocked and the sweat is trapped inside. This leads to swelling and skin irritation marked by tiny red bumps or rashes. Heat rash is very common in babies but it also affects adults who live in areas with hot and humid climates. Aside from the hot temperature, clothing which don’t give room for sweat to evaporate, certain creams, and bacteria such as Staphylococcus epidermis are also factors for the development of heat rash. But how long does heat rash last?
How to Treat Heat Rash?
Most cases of heat rash do not require any kind of medication. The rash begins to go away once the skin starts to cool down. Since heat rash is often a temporary condition, within 3 to 4 days, the skin is expected to be completely rash-free already. Most of the heat rashes just heal on their own. To relieve one of the symptoms of heat rash, start by wearing loose clothing and by staying at a cool and shady area. Simply allow the skin to air-dry and avoid scratching the rashes for it will only irritate them further. One may also use, if with an approval of a health professional, calamine lotion or any hydrocortisone cream to help relieve the irritation. Other lotions or ointments should be avoided since they can pose further irritation on the skin. Staying in cool places while wearing breezy clothes and limiting strenuous activities, will eventually ease heat rash and prevent any recurrences.
After 4 Days of Heat Rash!
However, if the rash does not seem to go away or if it gets worse after 4 days, then watch out for other symptoms of infection such as dizziness, nausea, rapid pulse, and fever or chills. When these symptoms are observed, apart from the usual itchiness and redness, then seeing a doctor is the best option. However, when these symptoms aren’t even present, then one should not worry too much about getting heat rash since it does not usually require any medication and can also be easily prevented. One should just basically know if he or she is at any risk of having heat rash.
Causes of Hear Rash
Adults who are most commonly affected by heat rash are people often exposed to the outdoors and great heat. Also, people who wear tight or heavy clothing with no room for air are also at risk of having heat rash. Definitely, people who live in hot places with humid conditions and those who are severely sunburned are also at risk. People who also drink alcohol are more probably going to develop heat rash compared with those who don’t. Individuals who suffer from obesity may also develop heat rash because of the folds of skin that trap heat. Individuals with other diseases and conditions such as psoriasis, eczema and cystic fibrosis may also develop rash. And individuals under certain medications that include antipsychotic drugs, and/or medications having anticholinergic effects, are also prone to developing heat rash.
