Cleaner bedroom air may help control blood sugar in people with prediabetes: Study

Using high-efficiency particulate air (HEPA) filters in bedrooms may help people with prediabetes manage blood sugar levels, a new study has found. Researchers found that cleaner air reduced daily blood sugar fluctuations by nearly 8% and morning blood sugar spikes after breakfast. The study involved over 150 people who used air filters for about a month.
