Jet lag can affect anyone and it can cause serious sleeping problems. A new study showed how you can get rid of jet lag. The study was made on mice and it was successful. The researchers wanted to study what affects the sleep and what people can do to cure jet lag.
Researchers found that if there are variations in the levels of oxygen, the circadian clocks can be reset. This was the case for the mice that were tested in this study.
Until this study, the things that could have helped with jet lag were temperature food and levels of light. These were the most important factors that could totally change the circadian rhythms.
The team of researchers published their study in Cell Metabolism and if other tests confirm their theory this could be a great step. The airlines could modify the air pressure in order for people to avoid jet lag.
In order to conduct this study, doctors changed the levels of oxygen that the mice were exposed to. They changed them by 3% twice a day. They observed that the circadian rhythm synchronized. The researchers also believe that the HIF1α is the gene that is linked to the oxygen and circadian rhythm. For instance, even if they changed the levels of oxygen when the mouse had low levels of HIF1α, the circadian clocks could not be synchronized.
“It was extremely exciting to see that even small changes in oxygen levels were sufficient to efficiently reset the circadian clock,” said Gad Asher, the leader of the study.
The researchers made different tests on mice to understand just how they are affected by a jet lag and how they can be cured. They are just like us and they can suffer from jet leg once daylight hours change suddenly.
The mice were left to eat, run, and sleep in an air-controlled environment. They did not suffer any change in their schedule until the researchers subjected them to a jump in daylight hours that totally changed their usual life.
After that, they changed the level of oxygen in order to regulate their sleeping and eating hours. They noticed that if the levels of oxygen were dropped 12 hours before a shift in daylight, it helped the mice stabilize their internal clock without suffering from a jet lag.
Let’s hope that researchers prove this is available for humans too.
