(PhysOrg.com) -- Jet lag, as every long-distance airline passenger knows, disrupts the body's normal circadian rhythms, or body clocks, and causes some very unpleasant effects such as disturbed sleep and fatigue. Now scientists ...
Fresh insight into how biological clocks adjust to having less sunlight in the winter could help us better understand the impact of jet lag and shift work.
