What do you needs to avoid when you have a fungal skin infection like jock itch?

Heat, moisture. Skin fungi love warm, damp areas such as the groin and feet, which is why jock itch and athletes' foot are so common. Your job is to keep the involved area as cool and dry as possible. In the case of jock itch, wear loose underwear and apply a good powder like zeasorb twice a day. And of course, apply a good antifungal cream or lotion twice a day until the rash clears.
