A recently published study of 43 older men and women shows that swimming a few times a week lowered their systolic blood pressure. On average, systolic readings—the “top” number in a blood pressure reading—were 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.”
Swimming is often promoted as a good way for older adults to exercise. It also offers them the ability to work their body without harsh impact to their skeletal system.
When the body is submerged in water it automatically becomes lighter. Depending on how much of the body is submerged, the amount of weight the body bears can be reduced by as much as 90 percent.
