<a href="http://www.arablocator.com/espana/who-buys-viagra-now.html" title="Viagra"> prescribe Viagra</a> reduces hamster 'jet lag'
The "little blue pill" given to treat impotence might also help people overcome jet lag faster, a new study in rodents suggests.
Hamsters that received small doses of sildenafil, sold under the name Viagra, adjusted more quickly to laboratory simulations of a six-hour time-zone change than animals in the control group.
The researchers found that a single dose of sildenafil helped the animals adapt up to 50% faster than usual. They believe that because a one-off dose had this large an effect in hamsters, the drug might offer a simple way to combat jet lag in people.
For humans, a general rule of thumb is that each hour in time difference between the origin and destination of a flight causes an extra day of jet lag.
Researchers believe that Viagra helps protect against jet lag because the drug raises levels of a small molecule called cyclic guanosine monophosphate (cGMP) in the body. They explain that a spike in cGMP levels temporarily "speeds up" the internal body clock in the brain.
