Air pollution not only affects our lungs, but it also poses a serious threat to skin health. Recent studies have linked poor air quality, indicated by a high air quality index (AQI), to doubling the risk of psoriasis, a chronic autoimmune condition.

How does pollution worsen psoriasis?

Psoriasis, characterized by red, scaly patches on the skin, is influenced by genetic and environmental factors. Of these, pollutants in the air are being identified as a major trigger.

“Poor air quality has far-reaching effects on overall health, especially skin health,” Dr Rashmi Aderao, dermatology consultant at Ruby Hall Clinic, Pune, told IndiaToday.in.

“Pollutants such as particulate matter (PM2.5 and PM10), nitrogen dioxide and sulfur dioxide contribute to worsening psoriasis by triggering inflammation and weakening the skin’s natural barrier,” she said.

Pollution causes oxidative stress in the body, increasing free radicals that damage skin cells. This cellular stress leads to inflammation, which is a major factor in psoriasis.

Additionally, prolonged exposure to pollutants disrupts the skin’s protective barrier, making it more susceptible to irritation and flare-ups.

“Pollutants can also activate immune system cells, like T-cells, which mistake healthy skin cells for harmful invaders. This immune response leads to rapid turnover of skin cells, which worsens the condition,” Dr. Aderao said. She goes.”

People genetically prone to psoriasis are especially sensitive to pollution. Poor AQI may act as a trigger for the onset of psoriasis or worsen existing symptoms, emphasizing the important role of environmental factors.

Managing skin health amid pollution

To reduce the risks, Dr. Aderao recommends staying indoors during periods of high pollution and using air purifiers to reduce indoor pollutant levels.

For people with psoriasis, maintaining a strong skin care routine, including moisturizers and anti-inflammatory products, can help repair the skin barrier and calm flare-ups.

“Understanding how pollution affects psoriasis allows individuals to take proactive steps to protect their skin and effectively manage the condition,” advised Dr. Aderao.

With pollution levels increasing, awareness of its impact on skin health is important for managing chronic conditions like psoriasis.
