A new study suggests that a synthetic form of cordycepin, a compound found in a fungus, may help ease the pain of jet lag, Inverse reports.

The results were positive: In mice, scientists found that synthetic cordycepin drastically helped the animals adjust to time change. Normally when mice are exposed to an 8 hour time change — imagine flying from New York to Abu Dhabi — it would take them 10 days to adjust. The mice on cordycepin took only four days.

“We want to let people know that drastic and quick changes for our body clock are possible,” Zhang says.

The study was published Wednesday in Science Translational Medicine.
