What are the causes of deep痱?

The main causes of deep痱 (prickly heat) include: 1. High temperature environment: Hot and humid weather is the primary trigger for deep痱. During summer, high temperatures cause the body's core temperature to rise. Sweat secreted by the deeper sweat glands cannot evaporate quickly under such conditions, leading to sweat retention. 2. Lifestyle habits: Poor lifestyle habits, such as prolonged wearing of thick, non-breathable clothing, failure to bathe regularly, and neglecting skin hygiene, can increase the risk of deep痱. Additionally, maintaining the same posture for extended periods or prolonged sitting can lead to sweat accumulation, thereby triggering deep痱. 3. Physical factors: Some individuals, due to physical constitution, have more active sweat gland secretions that do not discharge efficiently, making them more susceptible to deep痱. Particularly those with weak thermoregulatory functions, such as the elderly and young children, are more prone to develop deep痱. 4. Environmental factors: Long-term exposure to humid and stuffy environments, such as hot and humid summers, tropical climates, or areas with poor air circulation, also increases the likelihood of developing deep痱.
