A new study suggests that, in addition to many other health benefits, vigorous exercise may help with dry, itchy eyes by increasing tear production and quality.
The study included 52 adults who were classified as "athletes" or "non-athletes" by the researchers. Athletes exercised at least five times per week, while non-athletes exercised no more than once per week.
Everyone took part in a treadmill-based exercise session. The researchers measured tear production and how long the tear film on the eye remained stable before beginning to dry before and after the sessions. While all participants experienced increases in tear quantity and quality following exercise, those in the athlete group benefited the most.
A healthy tear film not only keeps the eyes moist, but also protects them from irritants like dust or dirt, as well as dry spots, which can cause itching, stinging, or burning. The findings, published in the January 2022 issue of Experimental Eye Research, suggest that improving physical fitness and exercising for longer periods of time may be important ways to improve eye moisture.
