The termination of a small fresh trial may offer a salve to multitude occupy about the health effects of sitting all solar day at work . The study found that taking walking breaks as short as five minutes every half - hour can stabilize blood sugar and descent pressure level levels compare to prolonged sitting . People also describe feel in a better humor and less fatigued when they take these unconstipated walks than they did while always off their feet .
Sedentary behavior is an authoritative endangerment factor for various health conditions , from cardiovascular disease to type 2 diabetes . For many of us , it ’s the long periods of sitting we do at oeuvre or at household that make up the bulk of our inactiveness . study havelinkedprolonged sit to a great risk of high blood pressure , back and muscle problems , andeven certain Cancer , among others .
steady exercise does seem to mitigate much butnot necessarilyall of the negative effects of sedentary conduct elsewhere in our lives . So medico and health organisation regularly remind people to proactively conk out up the fourth dimension they spend sitting throughout the daytime . But exercise scientists at Columbia University say that there ’s been comparatively little enquiry into how to make these breaks as in force as possible .

“ guideline recommend that adults should ‘ sit less , move more . ’ But they do n’t give the public any specific advice about what to do , ” study author Keith Diaz , an associate professor of behavioral medicine at Columbia ’s Vagelos College of Physicians and Surgeons , separate Gizmodo in an email . “ Just like we have recommendations on how many fruit and vegetables we should eat on each day and how much we should exercise , we set out to find an answer for how to combat the hurt of sitting . Ultimately , we wanted to know : what is the least amount of move you have to do to prevent the wellness hurt of sit . ”
To do so , they levy 11 healthy adults to take part in a trial at the university . The volunteers all carry out five different sitting scenario . In the baseline circumstance , they sat for eight hours in an ergonomic chair , while being permit to read , work on a laptop computer or use their telephone . In the other four , they die on short walks for varying lengths of time at varying points of the day . These include : one minute of walk for every half hour of posing , one minute of walking for every hour , five moment of walk for every half hr and five minutes of walking for every hour . They also select lavatory respite as needed and ate regular repast . During each shape , Diaz ’s team celebrate track of Tennessean ’ blood air pressure and blood sugar — two coarse indicators of a person ’s overall health — and occupy out questionnaire .
Out of all the conditions , only one come out as the clear winner .
“ We found that a five - arcminute light walk every half hour was the only strategy that reduced blood sugar levels substantially compare to sitting all mean solar day . In particular , the blood sugar spike after eat was reduce by almost 60 % , ” Diaz tell . “ We also found that a five - min igniter walk every half hr deoxidise blood pressure by 4 to 5 points compared to model all day . ”
These benefits even extended to people ’s mental health , with voluntary reporting that they experienced less fatigue and an improved climate when taking five - hour base on balls every half hour . The team ’s findings werepublishedThursday in the journal Medicine & Science in Sports & Exercise .
The results are based on a very small sampling size , so they should be viewed with some caution . Diaz additionally notes that the elaborated solidifying - up they created in their lab wo n’t necessarily mull over the real world . But these conditions also think that the writer could moderate for other variables that would make it backbreaking to ascertain the optimal walking fracture . And at the remnant of the mean solar day , no one disagrees that walking in ecumenical is good for your wellness , no matter how much of it you could do . Indeed , while the five arcminute of walk every half minute was the best option in the trial , even myopic and less frequent breaks still led to meliorate pedigree insistence spirit level on average for volunteers .
Diaz hopes their research can further highlight the perils of prolonged sitting and why employer should do something about it . dedicate the prompt benefit on hoi polloi ’s genial health , these breaks might even make for a more productive workplace , though that ’s of course secondary to people ’s health .
“ at last , there will need to be more studies that reduplicate our determination . But I do n’t think we should go along to hold off . There is enough grounds now about the wellness harms of model that employers should be promoting and encouraging regular suspension from sit , ” Diaz say . “ How often and for how long may still need to be sorted out , but our determination are a dear start point . ”
The investigator are already knead on their next study , which will bet to test out 25 strategies for offsetting the harms of seance — including function for wreak people who ca n’t take regular walking rupture , like truck and cab driver .
