If trials show the pill could reset the body's natural sleep rhythms, we could be getting rid of the annoying jet lag in the next few years.
The drug called Tasimelteon works by shifting the natural ebb and flow of the body's sleep hormone melatonin.

During the studies, this drug has been helpful for troubled sleepers in nodding off quicker and staying asleep for longer.

If it proves safe, the drug will be a good alternative to addictive sedatives like benzodiazepines and welcomed by millions of people from different professions (shift-workers, airline crew, tourists, football teams, etc)

The whole point of the drug is better performance. When you shift your body clock and yet sleep well, then you should perform well the following day.

The trials on 450 people, who were kept awake for five hours longer than normal to replicate crossing into a different time zone, showed that those people who took the drug enjoyed between 30 minutes and nearly two hours more sleep than those who received placebo pills.

Currently, body clock-related sleep disorders are treated with natural melatonin - the darkness hormone which peaks at night. However, the potency, purity, and safety of melatonin pills is not regulated yet. Additionally, there are mixed results about whether they work in shift-workers and people with jet lag.

The new drug works on the same receptors in the body as melatonin but more tests are needed to see if it would actually improve daytime performance and alertness without any carryover sedative effect.
