If a baby sweats a lot, they are likely to develop prickly heat rash. If the condition is not severe, simply clean the baby's skin with water and then apply prickly heat powder or prickly heat solution. If the condition is severe, it is necessary to take the baby to the hospital and follow the guidance and treatment of a professional doctor. Additionally, it’s crucial to maintain good ventilation in the room, ensure a healthy living environment, and adjust the baby's clothing timely according to weather changes. Avoid over-wrapping the baby. Bathe and wash the baby’s hair frequently to keep their skin clean. Regularly change the baby’s clothes, as well as the bed sheets and quilt covers, and expose them to sunlight often, as sunlight helps to disinfect.

Is prickly heat powder effective for children's prickly heat?

When children develop heat rash, using prickly heat powder is useful. Heat rash in children is caused by the blockage of sweat ducts in the skin, leading to a type of skin disease. Conditions such as poor development of sweat ducts in newborns, overly hot external environments, and prolonged bed rest can make children more prone to heat rash. Once a child develops heat rash, measures to cool and dry the skin are usually effective in improving the condition. Topical medications can also be applied locally, including ingredients like calamine, prickly heat powder, etc. The principles of using topical medications are cooling, itching relief, and astringency. The components of prickly heat powder include talcum, borneol, zinc oxide, and menthol, which can help remove dampness, disperse wind, cool the skin, and relieve itching. Therefore, using prickly heat powder is useful when children develop heat rash. (The use of medications should be carried out under the guidance of a physician)

Can prickly heat heal by itself?

Prickly heat, the disease, can heal on its own since it primarily results from excessive heat or blocked sweat, leading to the condition. Therefore, prickly heat can gradually heal itself if the temperature decreases, cooler weather prevails, or if one sweats less commonly. However, it is crucial to prevent infection, as if infection occurs, it is necessary to use some topical anti-inflammatory medications. Thus, prickly heat can heal on its own, but it is essential to prevent infection during this time.

How to remove baby's prickly heat

Baby prickly heat is mainly caused by the hot and humid living environment, which damages the skin. Therefore, it is important to enhance skin care, especially by improving the environmental temperature. Keeping the room ventilated by exchanging air is the best treatment method. If the skin symptoms are severe, Calamine lotion can be used, which can effectively alleviate the symptoms of prickly heat. The main treatment for prickly heat is prevention. Therefore, especially in summer, the clothes worn by infants should be loose and made of pure cotton. Avoid tight clothes or synthetic fabrics, as these can aggravate the symptoms of prickly heat by causing friction between the skin and the clothing. Also, pay attention to the diet and try to eat less spicy and stimulating food, choosing instead light and liquid-based foods. (The use of medication should be carried out under the guidance of a physician.)

The difference between prickly heat and heat rash

Prickly heat and heat rash are different. Prickly heat is a dermatological condition, commonly known as prickly heat, caused by high temperatures and hot weather when the body's sweating mechanism fails, resulting in the development of prickly heat on the skin. On the other hand, heat rash is a symptom that can appear in many diseases. Of course, prickly heat can also manifest symptoms of heat rash. Therefore, the difference between prickly heat and heat rash is quite significant.
