Jet lag, jumping a few time zones causes problems with sleep and even digestion. But new research means we could be a step closer to preventing this voyager’s vexation.

The study centers on the hormone vasopressin, thought to have a role in maintaining our internal clock.

Researchers genetically engineered mice that do not respond to vasopressin. Both engineered and normal rodents lived in a set cycle of light and dark for 2 weeks. Then the researchers changed the light cycle by eight hours. And the vasopressin-insensitive mice recovered from their induced jet lag much more quickly than did their hormone-sensitive peers.
