Measuring your blood pressure will be selfie, using a smartphone to shoot video of someone's face for two minutes, allowing your blood pressure to be read at an accuracy of up to 96 percent, according to a new study.

Researchers at the University of Toronto in Canada tested the program on an iPhone for 1328 people with normal blood pressure.

The technique works by capturing light reflected from the blood vessels behind the skin of the face to measure blood flow, relying on the facial skin that is too thin for light to travel through, and then bounces off the red protein, hemoglobin, according to the Daily Mail. ", Which carries oxygen in the blood.

The cameras of the phone are sensitive enough to capture the exact color of this reflected light so that the program can be used to track the movement of blood around the face, and by searching for the density and movement of blood in the cheeks, nose and forehead, can measure blood pressure accurately up to 96 percent.

The study, led by Dr. Kang Lei, asked people to take two-minute videos of their faces, but hopes to cut that time to 30 seconds without affecting the program's effectiveness.

Dr. Lee stressed that the program was not tested on people with very dark or light skin, although it was tested on people belonging to a variety of skin colors and types.

Dr. Lee explained that early tests showed that this technology is accurate enough to comply with international standards for blood pressure measurement, which confirms its importance and effectiveness, especially as high blood pressure is one of the main causes of cardiovascular disease and later death and disability, and this technology we prevent the occurrence Such things.
