Will Valkee's LED earbuds alleviate jet lag?

Finnair business travelers flying between Helsinki and Shanghai will soon have the chance to be test subjects on the effect that "brain stimulation" headphones have on jet lag.

The $240 earbuds, made and tested by Finnish company Valkee, already blast LED lights instead of music into desperate and willing ear canals with the intention of alleviating seasonal affective disorder. (The company has claimed, too, that the light helps improve reaction time--at least in Finnish hockey players.)

Now Valkee is working with the airline Finnair to determine whether the lights may instill a sense of well-being in long-distance … Read more

Mood-lifting bright light improves...reaction time?

It's often the case that a device or substance with a known benefit also comes with known risks--typically referred to as side effects and listed quickly at the ends of commercials. So it seems worth noting when a product's side effect may in fact be useful.

The Valkee, a portable headset launched in August of 2010, directs 8- to 12-minute doses of bright light through the ear canal and into the brain to improve seasonal affective disorder. It turns out that this concentration of bright light into the brain may also improve motoric reaction time, according to a study conducted by Verve Research in Finland.

The placebo-controlled study (meaning some were given the treatment and others a placebo in its place) tested the effects of the Valkee headset on Finnish national league ice hockey players and found that those exposed to 12 minutes of light via the headset sped up their already fast reaction times by 20 percent.

"The placebo-controlled study showed a significant improvement in motoric reaction times of top athletes using bright light via the ear canal," says lead researcher Mikko Tulppo in a news release.… Read more
