Jet lag that happens due to traveling to various locations in different time zones often leads to loss of appetite, insomnia, decreased alertness and depressed mood. Jet lag is not liked but becomes unavoidable sometimes but now new insight into the molecular mechanisms responsible for resetting the internal clock in the mouse has been provided by Gregor Eichele and colleagues at the Max Planck Institute for Biophysical Chemistry in Germany.

A major key observation made by Eichele is that if the speed with which adrenal gland shifts its rhythmic production of hormones is modulated then resetting of the entire internal body clock can be regulated.

According to the observers new therapies can be made to overcome jet lag by their observations.

Mary Harrington at Smith College, Northampton, said, “It will be important to determine whether treatments for jet lag that allow the body clock to shift rapidly are actually better for one's health than the slower adjustments that occur naturally”

But Eichele and team believes that jet lag can soon see therapies meant for treating it.
