Dealing with heat rash in children: Heat rashes, also known as prickly heat or miliaria problems, are very common in the hot summer months. But, they can be a source of discomfort and distress in children, with parents often feeling helpless while dealing with the situation. It has often been seen that a rise in temperature can cause these rashes to appear on the skin, leading to pain and general discomfort in kids. Read on to know all about the preventive measures that you, as parents, can follow.

Why Does Heat Rash Happen?

According to Dr Amit Gupta, a senior neonatologist and paediatrician at Motherhood Hospitals, Noida, heat rash tends to appear in the hot and humid weather, when the sweat glands become 'blocked' and 'inflamed'. It can trap the sweat under the skin, resulting in heat rashes that appear to be painful-looking small red spots or even blisters, with a prickling sensation that can cause pain, burning sensations, and discomfort in children.

"Infants and toddlers are more prone to heat," the doctor says, adding that the most common places for the rashes to appear are the face, the neck, back, and the torso. It can be a source of worry for parents, and while it looks uncomfortable and painful -- making the child fussy -- heat rash is usually harmless. It resolves on its own with basic care.

  1. Cool water application: Consider placing a cool, damp cloth on the affected areas of the skin to soothe them. This practice can reduce inflammation and provides relief from itching or prickling sensations.
  2. Keep the skin dry, cool: Make sure that your little one wears light and loose cotton clothes that allow the skin to breathe; these clothes can make the sweat evaporate easily. Avoid tight or synthetic clothes. The child must avoid playing outside in the sun during peak heat hours. At home, fans or air conditioners can keep the environment cool and comfortable.
  3. The use of gentle powders: Give your child mild and non-medicated powders -- like calamine or plain talcum (unscented) -- to keep their skin dry and irritation-free. Avoid powders that have strong fragrances, menthol, or camphor.
  4. Stay away from creams, ointments: Unless prescribed by a doctor, stay away from thick creams or ointments, as they can block the sweat glands further, aggravating the rash. Only use medicated topical treatments if there is redness, swelling, or pus. Check with a doctor.
  5. Stay hydrated: It is important to drink a lot of water in the summer months. Staying hydrated can help regulate the child's body temperature, and prevent overheating and skin problems.
