Blue light beats pills

Weekend Gold Coast Bulletin - - NEWS -

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 sun­light low­ers blood pres­sure, with peo­ple less likely to have high blood pres­sure in sum­mer.

But ex­ces­sive amounts of ul­tra­vi­o­let light, from the sun or a tan­ning bed, can cause skin can­cer. Univer­sity of Sur­rey re­searchers found a so­lu­tion us­ing blue light, which is close to ul­tra­vi­o­let in the light spec­trum.
