Red bumps on chest in hot weather

Because the weather is too hot, many people will get red bumps on their chest. Due to the special location of the disease, many people choose to just bear with it and not seek medical treatment in time, which may also cause other complications. The following is an introduction to the cause of this phenomenon and how to treat it. The treatment process includes local medication and systemic medication. This needs to be determined based on the condition and its cause to choose the method that suits you.

When the temperature changes, the rash and itching may disappear on their own without leaving any traces. This kind of rash that appears one after another should be urticaria.

Oral desensitization drugs such as loratadine or cetirizine can be used for treatment. If this situation lasts for more than 6 weeks, it indicates chronic urticaria and requires oral pidotimod liquid to regulate immunity.

Prickly heat is a common superficial, inflammatory skin disease in summer or hot environments. Because in a hot and humid environment, a large amount of sweat is not easy to evaporate, causing the stratum corneum to be soaked and swollen, and the sweat gland ducts to become narrow or blocked, resulting in sweat retention and sweat infiltration into the surrounding tissues, forming papules, blisters or pustules, which are more common in the folds.

Due to the high temperature and humidity in the environment, sweating is excessive and not easy to evaporate. Sweat soaks the stratum corneum of the epidermis, causing the opening of the sweat gland duct to narrow or become blocked. After sweat is retained in the sweat gland duct, it ruptures due to increased internal pressure. The overflowing sweat penetrates and stimulates the surrounding tissues, causing papules, papulovesicles and small blisters to appear at the sweat pores. Bacterial multiplication and toxin production can aggravate the inflammatory response. Some people believe that the blockage of sweat pores is due to primary staphylococcal infection, while others believe that the occurrence of prickly heat has nothing to do with excessive sweating, but is related to the massive proliferation of micrococci on the skin surface.
