Dirty Air Fuels Multiple Sclerosis Threat
4 Apr
Summary
- Air pollution tied to 21% higher MS risk with PM2.5 exposure.
- Short-term pollution exposure worsens MS symptoms and relapse.
- MS impacts 2.8 million worldwide, costing US billions annually.
New research indicates a concerning connection between air pollution and multiple sclerosis (MS), a disease affecting millions globally. A comprehensive review of 22 studies involving over 16 million individuals found that long-term exposure to fine particulate matter (PM2.5) is associated with a 21% increased risk of developing MS.
Exposure to slightly larger particles (under 10 micrometers) showed a 20% increase in MS risk. While carbon monoxide and sulfur dioxide exposure did not correlate with developing MS, short-term exposure to particulate matter and other pollutants was linked to negative impacts like increased lesions, disease worsening, and heightened relapse risk.
MS affects 2.8 million people worldwide and incurs substantial economic costs. Air pollution, affecting 99% of the global population, is responsible for millions of premature deaths annually. This study reinforces public health initiatives advocating for cleaner air.
Efforts to combat air pollution include promoting electric vehicles, enforcing regulations like the Clean Air Act, and transitioning to renewable energy sources such as wind and solar power. These actions are crucial for mitigating health risks associated with polluted air.
