SICK­NESS ALERT

First News - - Science News -

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.
