Dr. Wang Xiaoyan
Main causes of miliaria (heat rash) in adults include:
1. Environmental factors: Prolonged exposure to high temperature and humid environments can prevent sweat from evaporating easily, leading to blocked sweat glands and subsequent development of heat rash. This is one of the most common triggers.
2. Personal habits: Wearing tight-fitting, non-breathable clothing or failing to clean the body promptly after engaging in heavy physical labor or vigorous exercise can also increase the risk of developing heat rash.
3. Physical constitution: Individuals with a naturally sweaty constitution are more prone to heat rash, as their skin is more susceptible to irritation and blockage from sweat.
4. Skin health: Skin conditions such as eczema and urticaria, as well as issues like clogged pores and excessive sebum production, may also contribute to the occurrence of heat rash.
