Car air-conditioning does more than keep you cool on those long road trips. It also has an intriguing health boost…

Car air-conditioning is better for your heart than driving with the windows open. Heart-rate variability—a measure of cardiovascular health—was 32% better in people who ran air-conditioning during a two-hour commute than in people who drove with open windows. Possible reason: Air-conditioning filters exhaust particles and pollutants that cause internal inflammation and disrupt the heart’s electrical signals.

So roll up the windows and turn on the air on those long rides!

This tip was based on a study by researchers at Taipei Medical University, School of Medicine, Taiwan, published in Science of Total Environment.
