health π¨ HEPA air purifiers boost brain function in adults
A new study found that using a HEPA air purifier for one month improved brain function in adults aged 40 and older. This research was conducted on 119 people in Somerville, Massachusetts, which has high traffic pollution. Forty-two percent of the participants showed a 12% faster completion time on tests measuring mental flexibility. This small gain is comparable to benefits seen from increasing daily exercise. Further research will explore if longer use can sustain or increase these cognitive improvements. π§
