A little shifting in the oxygen levels in the air travel could act as a " reset " button for the biological clock , according to a new study in mice .
mouse in the field that were scupper to a brief dip in the grade of atomic number 8 in the air that they were breathe adjusted more quickly to a new circadian rhythm than shiner that received steady levels of atomic number 8 , the investigator come up .
In other words , the angle of dip in oxygen levels seemed to help the animalsadjust to the mouse equivalent weight of jet lag , according to the bailiwick , which was published today ( Oct. 20 ) in the journalCell Metabolism .
The thought of alter oxygen levels may vocalise scary ; however , the oxygen levels to which the black eye were expose in the report were not so low that they were harmful . The levels used in the experiment were standardised to the oxygen levels vernacular on plane , the investigator , led by Gad Asher , a aged scientist at the Weizmann Institute of Science in Rehovot , Israel , wrote in their study .

The research was aimed at develop a better intellect of a torso ’s circadian speech rhythm , orbiological clock . The clock is plant in the mental capacity of all mammal , and it somehow communicate with almost every jail cell throughout the body , but scientists have not known how this communicating happens .
In mice , atomic number 8 level in the cells fluctuate throughout the twenty-four hours , according to the study . The research worker declare oneself that O might be the wanting signal .
In several experiments , they found that oxygen stage in the cells of mouse appear to increase at Nox , when they are alive , and decrement during they day , when they are at rest .
Next , the researcher set out to watch if changing the levels of oxygen in the air the mouse were breathe could also vary the circadian calendar method .
In a laboratory experimentation , the researchers changed oxygen degree in the air by 3 percent , and determine that they were able to"reset " the circadian clocksof electric cell growing in lab saucer .
Then , in an experiment in mice , the researcher expose the creature to either oxygen floor that remain unchanging at 21 percentage ( this is the percentage of O in the air we breathe at ocean level ) , or levels that started at 21 percent , dipped down to 16 per centum for 12 hours , then rose back to 21 percent , consort to the study .
At first , exposing the mice to fluctuate oxygen stratum or else of stiff stratum had no effect on their circadian cycle , they retrieve .
But when the scientist also added in jet retardation — by exposing the mouse to " daylight"six hour ahead of agenda — the difference of opinion in oxygen levels take on a role . When the jet - jug mouse were reveal to the magnetic dip in O , they were able to adjust to a new eating , sleeping and activity docket more quickly than the computer mouse that did n’t experience any change in oxygen levels , the researchers found .
Because the study was done in cells and animals , it ’s not clear if the results also lend oneself to humans .
However , the researchers remark thatoxygen levelson plane are lower than oxygen levels on the ground . Because some hoi polloi report airsickness due to these lower stratum , the aviation industriousness is apparently investigating an increment in oxygen levels on planes to 21 percent . pass the findings of the study , however , doing so could have a minus impact on honey oil lag , the research worker wrote .
In succeeding experiment , the investigator would like to see if high levels of oxygen could also shift an animal ’s circadian rhythm .
" I trust passenger [ on plane ] might be more enthusiastic to inhale oxygen - enriched airwave to alleviate jet lag in dividing line to down oxygen " atmosphere , Asher said in a statement .
