A growing number of studies show the harmful effects of air pollution on diabetes. According to the Global Burden of Disease Study by Lancet, around 20% of the global burden of type 2 diabetes is linked to exposure to PM2.5. With 99% of the world’s population living in areas where air pollution exceeds WHO guidelines, the connection between air pollution and diabetes is becoming a significant concern.
The Science Behind the Link
Today, over 536 million adults globally are living with diabetes, and this number is expected to rise to 783 million by 2045. Exposure to fine particulate matter (PM2.5) has been shown to increase blood glucose levels and glycated hemoglobin (HbA1c) in both healthy individuals and those with prediabetes or diabetes. In India, where air pollution is linked to over 2 million deaths annually, the rise in diabetes only adds to the growing public health challenge.
Who is Most at Risk?
While air pollution affects everyone, certain groups are more vulnerable:
- People with existing health conditions, such as obesity or heart disease, are at higher risk.
- Prenatal exposure to air pollution may increase the likelihood of developing gestational diabetes in pregnant women.
- Children exposed to air pollution may face a greater risk of developing type 1 diabetes later in life.
- People living in urban areas with high pollution and older adults are also particularly at risk.
Studies show that the presence of diabetes increases the risk of cardiovascular death by 1.5-2.5% in both men and women over 10 years.
How to Protect Yourself from the Diabetes-Air Pollution Link
While it may not be possible to avoid air pollution completely, you can take steps to reduce your risk of diabetes:
- Check the Air Quality Index (AQI): Use air quality apps or websites to track pollution levels in your area. Stay indoors when air quality is poor.
- Invest in an air purifier: A high-quality air purifier can help reduce indoor air pollution.
- Wear a mask: Consider using an N95 or KN95 mask, especially when air pollution is high.
- Clean your home: Regularly clean your living space to reduce allergens, especially during seasonal changes.
- Air-purifying plants: Aloe Vera, Spider Plants, and Ivy can help improve indoor air quality.
Dr. Devendra Kumar Singh, Professor and Head of the Department of Respiratory Medicine at Sharda Hospital, recommends these steps to protect yourself from both air pollution and its impact on diabetes.
