Let the (Sun) Light In

Amazing Wellness - - AMAZING NEWS -

We know that sun­light has mood-boost­ing ben­e­fits. Stud­ies also show that peo­ple with higher lev­els of vi­ta­min D, called the “sun­shine vi­ta­min,” have a lower risk of dis­ease. And now a new study pub­lished in the jour­nal Mi­cro­biome re­vealed that the sun of­fers an­other perk: it can kill dis­ease-caus­ing bac­te­ria. The study, con­ducted by re­searchers at the Univer­sity of Ore­gon, set up 11 iden­ti­cal doll­house-size rooms. Some of the rooms were ex­posed to day­light through reg­u­lar glass, some rooms were ex­posed to ul­tra­vi­o­let light only, and other rooms were kept com­pletely in the dark. The minia­ture rooms were then filled with dust to repli­cate an ac­tual liv­ing en­vi­ron­ment and placed out­side for 90 days, af­ter which the rooms’ bac­te­rial lev­els were tested. The rooms ex­posed to day­light had fewer germs than their dark­ened coun­ter­parts. In fact, the sun­lit rooms had 50 per­cent less vi­able bac­te­ria. How­ever, re­searchers did not ex­pect the UV rooms to per­form as well as they did. In fact, the rooms ex­posed only to UV light fared even bet­ter than the nat­u­rally lit rooms, as they had the low­est bac­te­ria lev­els of all. That said, re­searchers still do not know what the op­ti­mum level of light is — the per­fect amount for killing germs, that is — but they hope fur­ther stud­ies will yield this in­for­ma­tion so ar­chi­tects and builders can in­cor­po­rate this in­for­ma­tion into fu­ture de­signs.
