Skin Care and Diseases in Summer

Take home message from Dr Mithra Vasanth Vignesh: Sun is a double-wedged sword. Damage due to different type of  UV radiations from sunlight is way more than one can imagine.

Living in a tropical country like India, our body and lifestyle must be adaptable to endure the scorching sun. Sweat related skin conditions, infections and rashes due to sun sensitivity are common in this season.

Bathing twice and switching over to loose cotton wear is one of the important changes that must be done to avoid sweat related complications. Retention of sweat is common in areas that are covered by clothes like inframammary, groin, and underarms. Sweat serves as a medium for some organisms to grow which may lead to secondary bacterial infection and superficial fungal infections. One must be aware that superficial fungal infections known as Padarthamarai (colloquial tamil) can spread from one person to another due to close contact. It is also advised to not share personal items, toiletries and clothing to avoid spread of infections. These practices must be followed even otherwise. In current scenario, patients resort to over-the-counter (OTC) medications which may be a cocktail of steroid, antibiotics and anti-fungal for faster remedy. These OTC medications may give temporary relief but the infection gets exacerbated after a point of time and patients may have to extend the treatment with proper medications later. It is advised to meet a dermatologist immediately to get a proper treatment to avoid spread of infection in one self and others.

Some people may develop rashes on sun exposed areas like face, upper back, hands and neck due to sun sensitivity. These rashes may cause trouble in the form of itching and redness. These rashes can spread and sensitise all over the body if left untreated. Regular application of sunscreen and physical protection in the form of umbrellas, wide-brimmed hat, fully covered clothing and sunglasses must be followed religiously to avoid sun sensitivity rashes. Choosing a right sunscreen depending upon your skin type, lifestyle and other conditions is essential. OTC sunscreens may not be adequate or not suitable or even may contain ingredients that cause hormonal disruption. It is advised to meet a dermatologist once to sort out a proper skin care routine.

Healthy diet and adequate hydration play a vital role in the overall health. Skin is the reflection of internal health. Heat boil can occur in areas of repeated friction and wrong method of shaving. Co-morbidities like diabetes mellitus, thyroid issues and vitamin-D deficiency must be addressed to avoid skin related conditions. Hair must be washed frequently to avoid built-up of sebum which may lead to inflammation, dandruff and seborrheic dermatitis. Oil application must be done only for hair for a short period like 5-10 minutes before hair bath. Avoid applying oil on scalp and stepping out with oily hair can attract more dirt and pollution.
