Another advantage of exercise is improved eye comfort.
A recent study reveals that, in addition to many other health benefits, strenuous exercise may assist with dry, itchy eyes by increasing tear production and quality.
The study comprised 52 adults who were classified as “athletes” or “non-athletes” by the researchers. Athletes exercised at least five times every week, but non-athletes only exercised once per week.
A treadmill-based exercise session was completed by all of the participants. The researchers measured tear production and how long the tear film on the eye remained steady before drying before doing eye tests five minutes before and after the sessions. After exercise, all participants saw an increase in tear quantity and quality, but those in the athletic group showed a higher increase in tear quantity and quality.
