The Claim

A single 30-minute session of moderate-intensity aerobic exercise, such as treadmill running, is associated with a significant reduction in intraocular pressure by approximately 2.1 mmHg in individuals with primary open-angle glaucoma and by 1.0 mmHg in healthy individuals.

Source: Aerobic exercise reduces intraocular pressure and expands Schlemm’s canal dimensions in healthy and primary open-angle glaucoma eyes

In plain English

One 30-minute session of moderate aerobic exercise, like treadmill running, reduces intraocular pressure by about 2.1 mmHg in people with primary open-angle glaucoma and by 1.0 mmHg in healthy people.

See the scientific wording

A single 30-minute session of moderate-intensity aerobic exercise, such as treadmill running, is associated with a significant reduction in intraocular pressure by approximately 2.1 mmHg in individuals with primary open-angle glaucoma and by 1.0 mmHg in healthy individuals, suggesting a transient but clinically relevant effect on ocular pressure regulation.

Why this might work

When a person exercises, blood flow increases throughout the body, including around the eye. This changes the pressure in the veins that drain fluid from the eye, which pushes more fluid through a drainage channel called Schlemm's canal. The canal stretches open, allowing more fluid to leave the eye, which lowers the pressure inside the eye.

  1. Study: Aerobic exercise reduces intraocular pressure and expands Schlemm’s canal dimensions in healthy and primary open-angle glaucoma eyes

    A 30-minute jog lowered eye pressure in both people with glaucoma and those without, with a bigger drop in people with glaucoma—exactly what the claim says.
