Nowadays, checking your vital body parameter is easier than never. Just buy a smartwatch and install the necessary applications from their app stores. The tasks that these wristwatches can perform are checking blood pressure, blood sugar level, pulse rates, etc. When there's something wrong with your body parameter (high blood pressure for example), the watch will send alarm, reminding you to chill and keep your blood pressure from going even higher.
Edgar Raymond, a hypertension specialist at the Johns Hopkins University School of Medicine, said, “On the surface, this is a good idea. People really want to have it. But the biggest problem is accuracy.” Assistant at the University of Vermont's Larner Medical School. Professor Timothy Plante agrees. Although using smart phones to measure blood pressure will change the "rules of the game," it is still too early to say that if the device will work. He hopes to see the researchers conduct tests on more patients. Otherwise, it is impossible to know if the device is accurate enough for use at home.
At present, the device has been tested on 30 individuals, 90% of whom can use the device properly after practicing once or twice. Most people involved in the test have normal blood pressure. Before a device is put on the market, it must be tested on at least 85 people with different blood pressure levels.
Researchers believe that once verified, the device can help people easily measure their blood pressure and determine if they need medication. Research shows that only about 45% of people in developing countries who have high blood pressure know their condition. "If they know, then they can do something in life to reduce their risk of stroke and heart attack." By now, I guess the most convenient way to monitor our body health level is to wear a smart wristband which has many sensors to detect the heart rate, blood pressure, blood sugar and so on.
