A new Apple Watch study links a low number of steps taken to high blood pressure
What you need to know
- A new study used Apple Watches to measure steps.
- Wearers had their blood pressure checked weekly.
- Those who took more steps had lower blood pressure.
New research has identified that those who take more steps during their days tend to also have a lower blood pressure than those who are more sedentary. As a result, those who ran the study believe they know how many steps someone should take to achieve a "normal" blood pressure.
Researchers at the University of California, San Francisco strapped Apple Watches to 638 people for at least five hours per day over a period of a month. Those same people also had their blood pressure measured weekly to see whether there was any link between the two. As The Inquirer reports, there most definitely was.
The researchers noted that taking 10,000 steps per day could be the difference between someone achieving a "normal" blood pressure reading, or one that was considered to be high.
While the team is keen to point out that the relationship between steps and blood pressure is observational rather than necessarily one of cause and effect, that isn't the only point of note here. This study is one of the first instances of an Apple Watch being used in such a study, with smartwatches as a whole likely to have an increasingly important role in the tracking of physical activity and its relationship to other body measurements and statistics.
Apple has long marketed Apple Watch as a fitness device, adding new features like support for taking an ECG and more.
