NYU Langone study links home air purifiers to lower blood sugar spikes in prediabetes

Using air purifiers at home for a month cut levels of harmful air pollution tied to blood sugar spikes and diabetes by 36 percent, according to an NYU Langone Health study of 75 New Yorkers with prediabetes presented at an American Heart Association conference. Participants who slept in rooms with the machines saw an 8 percent drop in daily blood sugar spikes, with a similar drop among those who ate breakfast. The researchers say HEPA filters offer an easy, low-cost tool alongside healthy eating, exercise and medication.
