Heat rash in babies: Symptoms, Preventions and Treatment

Babies and small children in particular develop an itchy skin rash at high temperatures. Here you can find out which symptoms you should look out for with heat rash and what you can do about the rash!

Especially in summer , as soon as the heat rises or the humidity is extremely high, nasty heat pimples, also known as heat blisters, can mainly occur in babies and toddlers. Heat sores are not dangerous and are not contagious. The blisters are just a sign that your child is dressed too warm and needs to cool down. Failure to cool your baby or toddler could result in heat stroke.

Heat rash symptoms

Heat rashes are recognizable by a red, pimply rash on the skin. If this is caused by increased sweating in intense heat and is also extremely itchy, it is medically referred to as miliaria . The rash is also known as heat rash and sweat rash. Babies and small children in particular suffer from the rash, the reason for this is often too warm and airtight clothing.

The rash occurs when the sweat glands produce more sweat than usual, clogging the pores. The pores of babies and toddlers are still very small, which means that clogging of the pores can occur more easily and, above all, faster. This happens mainly on covered parts of the body, such as on the stomach, on the back, in skin folds and in the diaper area. Small, red spots appear, which can develop into itchy or burning blisters with clear or milky contents. In order to rule out an allergy in any case and to be able to diagnose the nasty skin rash, it makes sense to consult a doctor for help.

Prevent heat rash

  • Feel the temperature on your child’s neck more often, it is important to keep an eye on it.
  • Your baby – like you – has to drink even more liquid when it is warm. Make sure you drink more fluids!
  • The complementary food should be lighter and cooler than usual in summer.
  • Depending on the heat, be sure to dress carefully. In strong heat, light-colored clothing made of cotton is always better than synthetic materials.
  • Babies often have little hair to protect them from the sun. Therefore, put some headgear, such as a hat or cap, on your child to block out the heat rays that can cause sunstroke.
  • Avoid direct sunlight so that your child does not sweat unnecessarily. However, always remember to use sunscreen with a high sun protection factor . Sun protection for the pram or the car is also useful.
  • When it is extremely hot, you should avoid the middle half of the day to go outside with your toddler. Better to go in the morning or evening when it’s still reasonably cool.
  • Baby powder and other care products should only be used in moderation on very hot days, as these products can also clog pores.
  • Your home should be at a comfortable temperature, ventilate it at the right time to avoid a heat wave.
  • Never leave your child waiting in the parked car. After just a few minutes, the car can heat up considerably – a life-threatening situation for the little ones.

treatment of heat sores

If your child is already suffering from heat rash, cooling is the first aid measure. After that, you can continue the treatment with the following tips:

  • A pleasantly lukewarm bath is an effective aid against hot spots and skin rashes. Do not dry your toddler after bathing, a light dabbing is enough.
  • Run a washcloth under cool water and dab your child with it. Caution: The water should be pleasantly cool and not too cold.
  • Scratching should be avoided in any case to avoid inflammation.
  • The little patient now needs pleasant coolness, so get out of the heat and into a room with a pleasant temperature. Make sure there is no train.
  • Zinc ointment or silica gel can be applied thinly to affected areas to promote rapid healing.
  • If you are breastfeeding your child, you can put a little breast milk on the affected areas. Breast milk is rich in vitamins, minerals, trace elements and important fats that help your baby to heal wounds.
  • Avoid creams with a particularly high moisture content and wound ointments as these clog the pores.
  • Dress your child in loose, loose clothing.
  • Medication is usually not necessary.

If the rash does not go away within three days, if you have a fever or if the pustules are very painful, contact your pediatrician. There may be another skin disease such as rubella, chickenpox or scarlet fever that needs to be investigated.
