Maharashtra Woman Links Severe Psoriasis Flare-Ups to Air Pollution at Work

A 76-year-old woman from Maharashtra, India, has linked her severe psoriasis flare-ups to air pollution at her Airbnb workplace. Babytai Suryavanshi, who works at a sugarcane nursery in Jambhali village, developed worsening symptoms after prolonged exposure to smoke from burning sugarcane residue and plastic trays. Her husband, Mahadev, was also diagnosed with the same condition, raising concerns about the health risks of polluted air in their community.

Psoriasis, a chronic autoimmune disease, causes red, scaly patches on the skin due to an overactive immune system. Globally, around 125 million people are estimated to live with the condition, though many cases—especially on darker skin—go undiagnosed or misidentified. In 2021 alone, 42.98 million diagnoses were recorded, but experts believe the true number is far higher.

Air pollution, which affects 99% of the world's population, may play a key role in triggering and worsening the disease. Fine particulate matter, nitrogen dioxide, and nitrogen oxides in polluted air can alter proteins and fats in the skin. These changes weaken the skin's protective barrier and reduce its antioxidant defences, making it more vulnerable to inflammation.

Research suggests that pollutants activate immune cells, leading to the release of inflammatory molecules that drive psoriasis flare-ups. A specific gene, ZMIZ1, may also be involved in how air pollution increases the risk of autoimmune reactions. For Babytai and Mahadev Suryavanshi, the constant exposure to smoke at the nursery likely contributed to their condition.

To reduce risks, health experts recommend staying indoors on high-pollution days, using air purifiers, and covering exposed skin with protective clothing. These measures may help lower the chances of pollution-related skin damage and autoimmune responses.

The Suryavanshis' case highlights the growing concern over air pollution's impact on skin health. With nearly the entire global population breathing unsafe air, conditions like psoriasis could become more widespread. Simple protective steps may help, but broader efforts to improve air quality remain critical for long-term prevention.
