Jet lag happens not only in the brain but also separately in the liver, lungs and muscles as a whole watchmaker's shop worth of internal body clocks start to run out of sync, researchers say.

As light cycles change, different organs reset themselves at different rates, scientists studying rats at the University of Virginia found. This explains why many people feel so rotten after crossing several time zones.

''Each organism is a conglomeration of oscillators,'' said Michael Menaker, a professor of biology and leader of the team that published its findings in the journal ...
