How to Treat Prickly Heat

Every summer, babies are highly prone to heat rash. During infancy, they don’t yet know how to scratch, but as they enter the toddler stage, they often develop heat rash and frequently scratch it with their hands. Because heat rash is intensely itchy, constant scratching can lead to skin abrasions and even bleeding—making it uncomfortable for adults just to observe.

How to Treat Heat Rash

Treating heat rash includes eating more watermelon during summer and ensuring good indoor air circulation. Heat rash can be classified as either inflammatory or superficial; in some cases, antihistamines may be used as adjunctive therapy. Loratadine tablets are particularly effective for relieving prickly heat–induced discomfort. Since high temperature and humidity in summer commonly trigger prickly heat, simple home remedies can often provide relief. For instance, applying a fresh cucumber slice directly onto affected skin two to three times typically resolves the rash completely—especially effective in children. Another simple remedy involves using mugwort (Artemisia vulgaris) leaves: wash the leaves thoroughly, add ample water, boil for 30 minutes, then use the warm decoction for the baby’s bath.

The primary cause of prickly heat is elevated temperature leading to excessive sweating, with sweat unable to exit smoothly through the epidermis—resulting in blocked pores and characteristic prickling sensations. Therefore, the most critical aspect of managing prickly heat is maintaining a cool, dry environment. If prickly heat develops and ambient temperature and humidity in one’s work and living spaces are appropriately adjusted, symptoms usually resolve rapidly. Additionally, topical emollients or talcum powder may be applied to keep the affected skin dry and comfortable, thereby alleviating symptoms and accelerating resolution.

We recommend keeping the affected skin clean, dry, and comfortable to relieve associated symptoms. We hope this information proves helpful.
