The Claim

Three months of regular morning aerobic exercise (jogging 30 minutes, 20+ times per month at 50–70% target heart rate) reduces 24-hour intraocular pressure by an average of 2–3 mmHg in patients with primary open-angle glaucoma on prostaglandin therapy, with the greatest reductions observed during morning hours.

Cause and effect
1 study reviewed
In plain English

In patients with primary open-angle glaucoma taking prostaglandin therapy, three months of morning aerobic exercise at 50–70% target heart rate for 30 minutes at least 20 times per month lowers average 24-hour intraocular pressure by 2–3 mmHg, with the largest drops occurring in the morning.

See the scientific wording

Three months of regular morning aerobic exercise (jogging 30 minutes, 20+ times per month at 50–70% target heart rate) reduces 24-hour intraocular pressure by an average of 2–3 mmHg in patients with primary open-angle glaucoma on prostaglandin therapy, with the greatest reductions observed during morning hours.

Why this might work

When a person jogs in the morning, their heart beats faster and they sweat, which makes the blood thicker with proteins. This thicker blood pulls fluid away from the eye, so the eye makes less of the fluid inside it. Less fluid inside the eye means lower pressure in the eye, especially in the morning after exercise.

  1. Study: Analysis of aerobic exercise influence on intraocular pressure and ocular perfusion pressure in patients with primary open-angle glaucoma: A randomized clinical trial

    People with glaucoma who jog for 30 minutes most mornings for three months saw their eye pressure drop by a small but steady amount — especially in the morning — just like the claim says.
