  "account": "Clean air may be linked to better blood sugar control for people with prediabetes, according to new research presented at the American Heart Association Scientific Sessions. A team from New York University recruited 150 adults with prediabetes and split them into two groups. One group received air purifiers with HEPA filters for their bedrooms, while the other group received air purifiers without filters. All participants wore blood sugar monitors and had their room air quality measured throughout the study. After a month of exposure to either filtered or unfiltered air, the group with the HEPA filters experienced a 8 percent reduction in blood sugar swings and a 17 percent decrease in extra glucose after breakfast, as well as a 13 percent reduction in post-breakfast peak levels. Cardiologist Sharine L. Wittkopp, the study's author, suggests that cleaner air at home, particularly in the bedroom, may help people with prediabetes maintain steady blood sugar levels and reduce morning spikes. The study focused on fine particulate matter, specifically PM2.5, which is removed by HEPA filters but not ultrafine particles or chemical constituents of air pollution. Researchers believe inflammation may be the mechanism behind the link between air pollution and diabetes, as inhaled fine particles trigger immune system cells to release inflammatory signals that reduce insulin sensitivity and block glucose uptake.",
