Viagra for jet lag?

The little blue pill known for making time in the bed more enjoyable may also help weary jet travelers roll out of it in the morning.

New research shows Viagra may be the solution for travelers who suddenly find themselves needing to rise hours earlier as they cross time zones, at least if those travelers are hamsters.

A study at the Universidad Nacional de Quilmes in Buenos Aires showed that male hamsters who received an injection of sildenafil along with a 15-minute stimulation of light were able to adjust their internal clocks by six hours in roughly half the time that hamsters who did not receive the treatment took.
