Causes of Heat Rash
As said above, heat rash is caused when sweat glands are blocked, which leads to the forming of small red bumps. Heat Rash is more prevalent in humid or warm conditions, such as when the body of children get overheated during physical exercises, or when the skin is covered in ointments, lotions, or creams. Some major risk factors include:
– Physical exercise during the heat.
– Humid or warm weather during the summer.
– Moisture: Heat rash often occurs in areas of the body that moisture is trapped, such as around the diaper area, under the neck, or the armpit.
– Sweat glands in newborns are susceptible to this condition as they are less mature than those of older children.
– Use of lotions, creams, or ointments, which might block the sweat glands. [5]
