Video selfies could be used to test blood pressure

Video selfies could be used to take blood pressure readings in the future.

A study led by neuroscience professor Kong Lee of the University of Toronto saw the successful readings of 1,328 people of different skin types tested by the tracking of changes in the lighting reflecting off of them.

The testing took place in a controlled environment and it's not known if the same accurate readings could be achieved at home and all of the participants had a normal blood pressure.

On how this could improve traditional methods of carrying out blood pressure test, Lee said: "If future studies confirm our results and show this method can be used to measure blood pressures that are clinically high or low, we will have the option of a contactless and non-invasive method to monitor blood pressures conveniently - perhaps anytime and anywhere - for health management purposes."
