It may be clip to trench the desk chair : A new report tie-in sit too much each day with computer memory problem in halfway - age and older adults .
Researchers from the University of California , Los Angeles ( UCLA ) found that long stretches ofsedentary behavior — like spending all day in your desk chair — were linked to changes in a part of the adult brain that ’s vital for memory board .
Earlier enquiry has link up sedentary behaviour to an increase risk of heart disease , diabetes and premature death in middle - age and older adult . Thenew survey , published yesterday ( April 12 ) in the diary PLOS One , builds on this , focusing on inaction ’s impacts on the learning ability , allot to astatement from the researchers .
Specifically , the new subject field join sedentary behavior to cutting of themedial temporal lobe , a mentality region involved in the formation of newfangled remembering , the investigator said in the statement . Brain cutting can be a predecessor to cognitive downslope and dementia in middle - age and sure-enough adult , the researchers add together .

The report admit 35 people between the ages of 45 and 75 . research worker asked the participant about theirphysical action levelsand the modal number of hours per day they ’d spend sit over the previous week .
Then , the investigator scanned the participant ' brains . Using a eminent - resolution MRI scan , the scientists get a detailed look at the medial secular lobe of each player and identified relationships among this region ’s thickness , the participants ' strong-arm action levels and their sitting behavior , agree to the sketch .
The results showed that sitting for extended period of time was closely associated with thinning in the medial temporal lobe , disregardless of one ’s physical activity level . In other words , the study suggests that " sedentary behavior is a significant forecaster of thinning of the [ medial temporal lobe ] and that physical natural action , even at high levels , is insufficient to offset the harmful upshot of sit for prolonged periods , " the researcher said in the instruction .
The participants reported that they spend from 3 to 7 hours , on average , sitting per day . With every time of day of sitting each Clarence Shepard Day Jr. , there was an observed step-down inbrain thickness , fit in to the sketch .
And although the field of study found no significant correlations between physical activity layer and thickness of the medial secular lobe , the researchers said in the statement that " reducing sedentary doings may be a potential prey for interventions designed to ameliorate brain health in people at risk forAlzheimer ’s disease . "
The researchers noted that the study did n’t prove that sitting go to slight brain structures , but rather launch an affiliation between sitting for long period of time and thinning structures .
In addition , thefindings are preliminary , and although the studyfocused on hours spend sitting , it did not take into circumstance whether participant took breaks during prospicient stretches of sedentary behaviour . This , researchers said , could be a limit of their termination .
Going forward , the researchers said they contrive to follow people that sit down for farseeing periods of time each day , to determine if sitting cause the ascertained cutting . They would also like to explore the rolegender , weight and subspecies take on in the effect on head health to sit , harmonise to the statement .
