London: Getting over jet lag after a long haul flight may be as simple as changing the temperature, a new study has claimed. Scientists at Queen Mary College at the University of London found that human biological clocks are driven by alterations in body heat as well as changes in light. This means putting on extra clothes, drinking hot drinks and standing by a heater could improve the feeling of sleepiness caused by jetlag, the `Daily Mail` reported. Alternatively, if you`ve visited a cold country and return to a hot one, having a cold bath or stripping off could make you feel better. A study of jet lagged fruit flies showed a group of cells at the back of the brain was more important for clock-synchronisation at warmer temperatures. The researchers made fruit flies jet lagged by exposing them to daily temperature changes reflecting warmer or colder climates, to understand how temperature affects the circadian clock.
