A new study from Argentina finds that viagra can reduce the amount of jetlag in hamsters

A new study has found that the drug viagra, has shown the ability to reduce jetlag in hamsters.

Scientists from Argentina, found that the drug helped the rodents to recover up to 50% faster from forward shifts in their daily time cycles, however they also noted that the drug only worked when used in conjunction with light therapy and only worked in one time direction.

For their study, to shift time in the daily lives of the hamsters, the team of researchers switched on lights 6 hours earlier than they usually would and then monitored the amount of running on their wheels that the hamsters took part in.

The drug, which did not cause penile erections in male hamsters, allowed the hamsters to adjust to the differing time cycle faster, even when the drug was administered in low doses.

"This is a study in laboratory animals, and clinical trials should be undertaken before deciding whether Viagra is a useful and safe treatment for those
situations," said Diego Golombek, the lead investigator on the study.

He also stated that because humans and mammals have similar daily cycles, that "there's no reason not to believe it should work in humans."
