Jet Lag Cure: Could eye drops help reset body clock?
Scientists have found a link between the eye and the body clock which could lead to treating jet lag with drops.
They discovered a new group of cells in the retina which sends signals about light changes to the part of the brain that regulates the body's physiological activities.
Jet lag occurs when the body struggles to adapt to different times for light and dark after flying to a new time zone.
Researchers believe they may be able to use eye drops to manipulate the retina's signals and thus alter the body's responses to light changes.
Mike Ludwig, Professor of Neurophysiology at the University of Edinburgh and lead investigator of the study, said: "Our exciting results show a potentially new pharmacological route to manipulate our internal biological clocks.
