LIGHT AND SOUND STIM­U­LA­TION CAN BE USED TO DULL CHRONIC PAIN, NEW STUDY SUG­GESTS.

Stud­ies car­ried out in the UK sug­gest that the brain can be ‘tuned’ to cer­tain fre­quen­cies to al­le­vi­ate chronic pain. Sci­en­tists dis­cov­ered that al­pha waves from the fore­brain, as­so­ci­ated with placebo anal­ge­sia, in­flu­ence how the rest of the brain pro­cesses pain. Re­searchers used au­dio-vis­ual stim­uli — from gog­gles with flash­ing light or cer­tain sounds — in the al­pha range and found they ef­fec­tively re­duced pain, pro­vid­ing a po­ten­tially safe, sim­ple and low-cost tool to treat chronic pain.
