  1. Heat Rash

You can stop this by putting a powder/talcum on that part of the skin which dries the skin and prevents the humidity friction. There are also some products that have a cooling effect which can also prevent sweat at that specific area.

  1. Allergy Rash

An allergic reaction can happen due to many substances and sometimes it is difficult to differentiate which one caused the rash. This can be a food or even a certain drug ingredient which can develop in a few hours, so you won’t usually connect the cause with this event. It can start with red and itchy skin. It is important to see a doctor, where he will prescribe some antihistamine cream or some other drug.

  1. Contact Dermatitis

Contact dermatitis is also a type of allergic reaction which is caused by direct contact with the substance that irritates the skin. This can be a clothing piece to detergent, lotion, poison ivy and similar chemicals. This is also presented in a burning sensation with redness and itchy feel.

A “jock itch” it is described as a rash inside the man’s groin. This is related to fungal infection with tinea cruris, where “tinea” is the name of the fungi and “cruris” means leg. It affects inner thigh of men and women. It is related to sweating and constant humidity in that area combined with heat and bad clothing for exercise. This creates an environment which is perfect for fungi development. This is often in athletes, as an athlete’s foot which is caused by tinea pedis. The doctor can prescribe local antifungal treatment that you will have to apply maybe twice a day for at least two weeks. It is mildly contagious, only through direct contact or through objects that contain the fungus such as towels.
