Developed a lot of pompholyx overnight

Sudden onset of numerous dyshidrotic eczema (pompholyx) lesions overnight may be caused by physiological, psychological, or pathological factors. Patients should choose appropriate treatments based on the specific underlying cause. Detailed analysis is as follows:
　　1. Physiological factors
During summer nights, excessive sweating due to hot weather and inadequate skin cleansing may irritate local skin and lead to the development of dyshidrotic eczema. It's important to maintain a comfortable indoor temperature while sleeping, which can be achieved using air conditioning. However, avoid setting the temperature too low to prevent catching a chill.
　　2. Psychological factors
Having nightmares during sleep, leading to prolonged anxiety or tension, may cause excessive sweating and subsequently trigger dyshidrotic eczema. In such cases, it's essential to restore mental calmness; listening to soft music before bedtime may help promote relaxation and improve sleep quality.
　　3. Pathological factors
If a large number of fungi proliferate on the local skin area, they may provoke a rash-like reaction and induce dyshidrotic eczema. Under medical guidance, patients may use antifungal medications such as ketoconazole, miconazole, or clotrimazole for treatment.
In addition to the above causes, other possible conditions include sweat retention syndrome (miliaria), atopic dermatitis, or allergic diseases. Patients should consult with physicians and follow professional advice for symptomatic treatment to effectively alleviate discomfort.
