The common symptoms of heat rash are red bumps on the skin, and an itchy or prickly feeling to the skin. These are due to inflammation of the superficial layers of the skin (the epidermis) and the prickly sensation is similar to the feeling of mild sunburn.
A bouffant cap is a hat whose function is to keep stray hair in and water or other contaminants out. It resembles a bag with a gathered elastic opening that covers the hair and fits snugly around the hairline. A bouffant cap is traditionally used to protect a complicated hairstyle while sleeping or showering.
A surgical mask is used inside the operating room or during other sterile procedure areas to protect the patient environment from contamination. Surgical masks have ties so that they can be adjusted for fit, and are tied over the top of a surgical or bouffant cap.
