Iam 30 years old. Please give some tips on how to keep my skin and hair safe during summer, and excesssive itching and sweating at bay. Shanti Krishnan, Madurai
When an individual is exposed to a high environment temperature, the sweat glands are stimulated to secrete sweat. The sweat cools the body surface by evaporation and helps maintain the body temperature. However, persistent sweating for long periods of time results in the development of a skin rash called prickly heat. The rash is accompanied by intense itching on the body. Avoidance of direct sun exposure, frequent cold water baths, powdering the body and body folds with talcum powder and keeping oneself in a well-ventilated cool environment will help you beat the heat. Excessive perspiration also causes the scalp to itch. The scalp should be cleansed with a good shampoo to clear it of sweat, oil secretion, dust and dandruff. Shampooing the scalp does not cause hair loss.
