Doctors warn of spike in skin diseases due to heat

Bengaluru,

With heatwave-like conditions prevailing in a city which experiences mild weather the rest of the year, doctors have warned that it could be a perfect storm for a variety of skin issues to flare up. With the city also being quite polluted, along with sweat and bacteria, skin could very easily be affected with acne, rashes and blemishes, doctors warned.

“Emerging clinical observations and 2026 reports show that heatwaves create more than discomfort because they initiate and amplify skin flare-ups. India now endures its most severe heatwaves which last longer than before and health warnings indicate their harmful effects on various bodily systems that include skin health,” said Dr. Priyanka Kuri Dermatology Consultant at Aster Whitefield Hospitals.

“Acne is a prevalent skin condition during heatwaves. Sweat can clog pores, especially when combined with sunscreen and makeup, and cause irritation. Moreover, warmer temperatures can promote the growth of acne-causing bacteria. That's why we tend to experience breakouts on the forehead, back and chest during hot weather, as these areas are more likely to accumulate sweat. People who already suffer from acne may experience a flare up, and may need more intensive treatment,” said Dr Tanushree Biswas, consultant dermatologist and head medical advisor at Kaya Skin Clinic.

She added that dermatological treatments such as chemical peels and acne treatments can help regulate oil poduction and reduce breakouts while avoiding further irritation. Another major issue that arises is summers is skin rashes caused by heat exposure, blocked sweat glands and friction with clothes. “Medical treatments such as barrier-repairing and soothing treatments, moisturising facials and calming dermatological therapies can help with skin repair and inflammation if at-home topical treatments are insufficient,” Dr Biswas said about treating heat rashes.

While tanning and pigmentation also occur due to sun exposure, it is now common knowledge to use sunscreen to prevent this from occurring and also protecting the skin from UV light. “During heatwaves, the sun's UV light is stronger and the skin's melanin production speeds up to protect itself. This can lead to tanning, pigment irregularities and even persistent pigmentation disorders like melasma,” said Dr Veena Praveen, dermatologist at Kaya Skin Clinic.

She outlines several treatments one could do afterwards like skin lightening and laser therapy that can reverse this to an extent. She also warned that dehydration can worsen skin conditions and can sometimes make the skin look oily. But this can cause people to over-cleanse or neglect moisturising, which can cause sensitivity. Professional hydrating services, and using non-comedogenic and light skincare products, can re-balance the system.
