What causes itchy hands?

Itchy hands can be caused by various factors, mainly including the following: 1. Allergic reactions: Contact with allergens such as detergents, animal fur, pollen, or ingestion of allergenic foods like seafood may trigger allergic skin reactions, manifesting as redness, rashes, and itching on the hands. 2. Skin diseases: Conditions such as eczema, fungal infections (tinea manuum), and dyshidrotic eczema can cause symptoms including blisters, redness, peeling of the skin, and varying degrees of itching on the hands. 3. Environmental factors: Cold stimulation may lead to itching due to vasoconstriction. Additionally, insect bites during summer can also cause hand itching. 4. Other causes: Conditions such as urticaria and scabies infection may also result in itchy hands. Urticaria is often associated with temperature changes, infections, and psychological factors, while scabies infection may lead to the formation of small blisters on the hands accompanied by itching. Given the wide variety of causes for itchy hands, it is recommended to seek timely medical consultation based on specific circumstances to determine the exact cause and receive appropriate treatment.
