Why Do We Gasp for Air in the Extreme Heat? - I Spy Physiology Blog

If you live in a hot and humid climate, you may know what it’s like to feel as if you’re gasping for air on an especially hot day. For people with asthma or other chronic lung conditions, heat waves—which often coincide with dangerous ozone levels and humidity—may cause asthma flare-ups and breathing difficulties. This is … Continue reading Why Do We Gasp for Air in the Extreme Heat?
