Re­searchers see the light

Warwick Daily News - - WORLD -

BLUE light could work as well as drugs to lower high blood pres­sure, doc­tors have found.

Just half an hour of blue light in a day re­duces blood pres­sure to the same level seen in those tak­ing tablets.

It is well known that sunlight low­ers blood pres­sure, with peo­ple less likely to have high blood pres­sure in the sum­mer than win­ter.

The prob­lem is that ex­ces­sive amounts of ul­tra­vi­o­let light, from the sun or a tan­ning bed, can also cause skin can­cer.

Re­searchers at the Univer­sity of Sur­rey found a so­lu­tion us­ing blue light, which is close to ul­tra­vi­o­let in the light spec­trum.
