Dr. Wang Xiaoyan
Small blisters accompanied by itching on the hands during summer may be caused by the following conditions:
1. Tinea manuum (hand fungus): This may result from a fungal infection of the skin. The damp and sweaty conditions of summer skin create an environment conducive to fungal growth, leading to the appearance of small blisters on the hands.
2. Dyshidrotic eczema (pompholyx): When the body's immunity is low, this condition primarily manifests as blisters on the skin, accompanied by intense itching.
3. Eczema: High humidity in summer can lead to impaired sweat excretion, making the hands prone to eczema. Eczema presents with small blisters, redness, and itching, and the skin may become dry or start peeling.
4. Contact dermatitis: This results from an allergic reaction of the skin to certain substances, such as metals, chemicals, or specific plants.
