Shed­ding light on health con­cerns

Re. “City moves for­ward with switch to LED street lamps,” Feb. 13

The city mov­ing for­ward with the switch to LED street lamps should con­cern us all.

Blue light in­creases the risk of mac­u­lar de­gen­er­a­tion ( blind­ness) and can­cer of the eye. Fur­ther­more, ex­po­sure to LED light­ing in the evening can make it harder to fall asleep.

The Amer­i­can Med­i­cal As­so­ci­a­tion warns that LED street light­ing can have harm­ful ef­fects on hu­mans and the en­vi­ron­ment, and Ger­man physi­cian and pho­to­bi­ol­o­gist Alexander Wun­sch states that the wrong use of ar­ti­fi­cial light can have se­ri­ous health con­se­quences, from mac­u­lar de­gen­er­a­tion to breast and prostate can­cer.

The City of Ed­mon­ton is sav­ing money by re­plac­ing sodium street lights with LEDs, but what is the cost to Al­berta Health as we suc­cumb to in­creased rates of dis­ease?
