Answer From Sheldon G. Sheps, M.
But measuring it with a video selfie? Or with sensors built into your running shoes or sports watch? The only kinds of automated devices that have been validated for measuring blood pressure outside a health-care setting involve the use of cuffs on the upper arm or, in a few cases, the wrist.
And even some of those have not met international validation standards.

Briefly, the method is based on the principle that some ambient light is absorbed through the skin by hemoglobin, a protein in blood. An estimate of blood flow can be made based on the residual light that is reflected back to the smartphone camera.
As for the running-shoe sensor, it is still in development, according to a patent application from Under Armour Inc.
Still, some sports watches advertised as measuring blood pressure already are on the market. Cohen, who also specializes in kidney disease, is part of national and international efforts to compile lists of validated blood-pressure monitors for use in the home.
If their blood pressure returns to normal ranges outside the office, such patients might assume that there is little reason for concern. In July, Medicare coverage of home-based blood-pressure monitors was expanded for both types of patients.
The home-based devices measure blood pressure all day and night, with readings typically taken at or minute intervals.
By Conor Allison conorallison95 It's estimated that a third of American adults have high blood pressure, which puts them at a higher risk of heart attack or stroke.
The latest research suggests this round-the-clock collection of data can save lives. Elevated measurements over 24 hours and at nighttime both are associated with a higher risk of mortality, according to a study this month in the Journal of the American Medical Association. Yet even when people are aware they have high blood pressure, they often do not take steps to keep it under control, according to a recent study led by Temple University researchers.
The authors analyzed prescription refills for more than , patients under 65 who were prescribed medicines to lower blood pressure, such as ACE inhibitors.

In some cases, you feel worse. Failure to address the problem can lead to grave consequences such as heart failure, a stroke, or an aneurysm.
Broadly speaking, high blood pressure is a sign that the heart is being overworked, straining to pump blood through vessels that are narrowed or stiff.
