Blisters on the hands during the rainy season may be caused by herpes sweat or fungal infections, which can be treated through the use of medication.
1. Sweat herpes: Sweat herpes is a special type of eczema, which can be manifested as blisters on the hands with obvious itching. It can be treated by applying glucocorticoid ointment such as hydrocortisone ointment, and when itching is obvious, it can be treated with antihistamine drugs such as oral loratadine.

Blisters on the hands in the rainy season should go to the hospital for diagnosis and treatment under the guidance of a doctor.
