CFL migraine concern starts crazy wildfire

By Hank Green Posted Thu Jan 3, 2008 11:14am PST


There's a Daily Mail story making the rounds on the blogosphere with the headline "Energy Saving Bulbs 'Can Cause Migraines' Warn Experts." Oh come on ... are you serious?

Spend a little time reading the article and you discover that one 'expert,' who is in charge of a migraine awareness charity, said that there is "concern." He worries that it's possible ... that's all.

Is this really a story? Let's at least have someone do a study first, before the headline "CFLs Cause Migraines!!!" spreads like wildfire over the Internet. I mean, I love blogs, but I've seen this story retold in five different places now ... not one mentioning that it's just one guy who's concerned.

Not to say that I'm not happy for the level of concern. Concern is a good thing, and I think it should be investigated. But the truth is, the concern about migraine-inducing flickering is a non-issue with current CFLs, which are no longer stroboscopic (they give off constant, non-flickering, light.)
