According to one new research made with the aid of an Apple Watch, those who take more steps during the day also tend to have a lower blood pressure than those who are more sedentary.
University of California researchers provided several Apple Watches to 638 people for at least five hours a day, for an entire month, to monitor blood pressure weekly.
Over the course of about five months, the recordings showed that the participants recorded an average of around 7,500 steps per day. The average systolic blood pressure in the group was 122 mmHg and the average diastolic blood pressure was 76 mmHg, levels considered normal or slightly elevated, according to the ACC / AHA guidelines of arterial hypertension in adults in 2017.
The researchers also found that participants who had accumulated more steps each day exhibited significantly less systolic and diastolic blood pressure than those who walked less. For example, for every 1,000 steps taken each day, participants' systolic blood pressure was approximately 0.45 points lower, meaning that a person taking 10,000 steps per day would reduce their systolic blood pressure by 2.25 points, compared to a person who walks only 5,000 steps per day, on average.
The team wishes to emphasize that the relationship between steps and blood pressure is not necessarily cause and effect, but surely those who walk more during the day benefit from it. Nothing particularly new, just further confirmation that just a few steps a day are enough to improve your health.
This study is one of the first use cases of a Apple Watch, a fact that once again shows how smartwatches will probably have an increasingly important role in our daily lives both in tracking physical activity and for other measurements and statistics on the health of our body.
The latest Apple Watch models are also equipped with ECG able to generate a single-lead electrocardiogram, useful for keeping our health under observation.
