Come summer, the scorching heat and stifling humidity are going to rule the days without offering any respite and with them come the skin rashes to make life more miserable. However, heat and humidity are not the only causes for skin rashes, there are other reasons too. But irrespective of the causes, skin rashes generally have one symptom in common - that is frequent itching sensation.
Skin rash commonly happens when blocked skin pores resist perspiration under the skin. It can happen to anybody - be it a baby or an adult; however it is not always clear why the skin pores get blocked.
Heat or skin rashes commonly occur in the areas such as face, neck, under the breasts and genital(for women), and under the scrotum (for men). It also likely to appear on the places that relatively sweat more and also are frequently rubbed against clothing in those parts, such as back, chest, stomach, and lower leg.
Causes for skin rash:
Undeveloped sweat glands - Newborns are prone to skin rash because their sweat glands aren’t fully developed and can rupture easily. This results in trapping of perspiration beneath the skin and leads to skin rashes. Skin rash can develop in a baby as early as the 1st week after birth, especially if the newborn is kept in the incubator, or is wrapped with warm cloths, or has fever.
Tropical climates - Heat and humid weather can cause heat rash in people of all ages.
Prolonged bed rest - Skin rash can also occur if a person is under bed rest for long time, especially in case of fever.
Poison plants - Poison ivy, poison sumac, poison oak are some of the plants that trigger allergic reactions when one comes in contact with them, resulting in an itchy rash.
Allergic reactions to some items - Many people develop rashes from the contacts with some alloys, chemicals,etc. found in regular household items and cosmetic products.
Infections - Parasitic, fungus, viral, and bacterial infections cause skin rashes such as scabies, shingles, and impetigo.
Stress - Stress may cause rashes or hives for some people.
Skin rash treatments:
Some rashes can go with self-treatment, such as cleansing the affected areas thoroughly with water and soap, avoiding scratching as much as possible, keeping the affected area cool and dry, etc.
But other type of rashes which are more rigid types (lasts longer than seven days) do not get cured by self treatments and can even get worse if not treated by a doctor in time. A doctor can guess the root cause of the skin rash problem and may prescribe antibiotics and topical medicines.
