Allergies to Sweat in Children: Symptoms and Treatment

Last update: 21 December, 2018

Sweating is the body’s response to an increase in temperature. The sweat that evaporates from the skin cools the body. However, sometimes kids can develop allergies to sweat.

The common causes of sweating, which can worsen these symptoms, include sports, high temperatures and emotional stress.

Consequently, sweat can cause a skin reaction, creating blemishes and red spots. If this happens to your child, it’s important that you go to the pediatrician. He or she will analyze the cause and tell you what medication you need.

Babies and children have sensitive skin, and the increase in body temperature is what causes this allergy. While it’s true they can get rashes anywhere, they’re most common on their stomach and extremities. 

The appearance of spots usually causes itching and discomfort in children. They may also experience headaches or heart palpitations.

Types of allergies to sweat in children

Problems such as dermatitis, urticaria or dyshidrosis are associated with allergies to sweat in children. These are the three most common ones:

1. Atopic dermatitis

Atopic dermatitis is characterized by redness on the face. It appears on the forehead and cheeks. Additionally, it shows up on the head, wrists, elbows, knees, ankles and neck.

In general, atopic dermatitis can occur from contact with irritants such as soap and detergent. It can also occur because of heat and sweat.

We recommend you gently rinse and dry the child’s skin. This will prevent sweat or other irritating products for coming in contact with the skin.

2. Urticaria

The second type of sweat allergy appears on the skin with red spots and, sometimes, itching.  Inflammation mainly affects arms, legs and chest. However, it can appear anywhere on children’s bodies.

Urticaria can go away on its own in a few hours or days. However, this condition is very annoying. Therefore, consult your child’s doctor so he can prescribe a medication to reduce swelling and itching.

3. Dyshidrosis

Sweating and humidity are factors that cause this disorder. It can sometimes be painful for babies. This type of allergy is known as a skin disorder close to eczema. It usually affects their hands and feet.

This acute or chronic skin condition forms bullous lesions. The treatment is  usually local. Apply an antiseptic and anti-inflammatory ointment to relieve pain.
