Many older adults like to take a dip a pool, and now a small study suggests it can be good for their blood pressure. Researchers found that among 43 older men and women, those who started swimming a few times a week lowered their systolic blood pressure — the “top” number in a blood pressure reading.
On average, the swimmers started the study with a systolic blood pressure of 131 millimeters of mercury (mm Hg). Three months later, it was 122 mm Hg. Normal blood pressure is defined as an average reading no higher than 120/80 mm Hg. Readings of 140/90 or higher are considered high blood pressure, and anything in between is considered “pre-hypertension.”
