One of the downsides of international travel is the jet lag that comes with long flights that cross many time zones. Aside from staying hydrated and sleeping during flight, there’s not a whole lot the world traveler can do to combat jet lag. But, researchers at a Scottish university believe they may have found a cure — eye drops.
Scientists found a class of cells in the eye that are sensitive to light and help to regulate the body’s circadian rhythm, also known as the body’s biological clock. The cellular group, known as retinal ganglion cells, send information to the brain about light’s changing intensity, which controls sleep-related impulses. Researchers at the University of Edinburgh believe they can use this discovery to manipulate the body’s internal clock.
While still quite a way off, researchers believe eye drops could be used to alter signaling to the brain which could help reduce the effects of jet lag after traveling across the world. This may not help you on your next long-haul flight, but it’s encouraging to see scientists working towards a solution that could finally alleviate symptoms of jet lag that so many travelers currently can’t evade.
