DO you feel fine? Are you sure? Wouldn’t it be useful to know if you were coming down with an illness?
Scientists in California, USA have developed a smartwatch that can detect changes in your body that signal when an infection or virus has attacked.
More than 40 volunteers wore special watches that continuously monitored their pulse and skin temperature for two years.
The readings showed that unusually high heart rates and skin temperatures were spotted up to three days before a volunteer felt any symptoms of a cold or similar infection. In other words, the smartwatch knew a person was ill before they did.
Professor Michael Snyder of Stanford University says that monitoring a person’s “vital signs” is far more useful for diagnosing an illness than a doctor comparing a patient’s readings with the national average.
The team at Stanford now plan to develop a way for the smartwatch to alert a person before they become sick, so they can rest or change their plans to try and avoid becoming seriously ill.
