Continuous positive airway pressure (CPAP) therapy for obstructive sleep apnea (OSA) significantly reduces both nocturnal and daytime systolic blood pressure in patients with refractory hypertension.

If you have high blood pressure that won't come down despite taking multiple medications, ask your doctor about sleep apnea. If you have sleep apnea, using CPAP therapy nightly can significantly lower your blood pressure, both during the day and at night, potentially improving your long-term heart health.

Why this rating

The study is an interventional trial with a small sample size (n=11) and lacks a placebo control for the chronic phase, though the acute effects are robust.
