Does sitting stupid?

Hours of sitting, according to a recent study, shrink parts of the brain that play an important role in memory. Scientists at the University of California surveyed 35 subjects between the ages of 45 and 75 years to what they had been doing the previous week – how many hours a day they had been active, and how many hours they had spent sitting on average. The researchers then took MRI images (magnetic resonance tomography) of the brains of all subjects and looked more closely at the so-called temporal lobes (temporal lobes) of the subjects. They were interested in the thickness of a certain region of the temporal lobe, the so-called medial part – because there sits the hippocampus, which among other things is responsible for the transmission of information from short-term to long-term memory. Per less hour spent in sitting less brain The evaluation of the results showed that the more hours the subjects had spent sitting on average (according to the study participants that was three to seven hours), the thinner was their medial temporal lobe. This association persisted, regardless of the amount of physical activity – with after-work sports can not compensate for the disadvantage for the brain accordingly. The study has some limitations – these include the small number of subjects and the relatively short period of one week, which served as a “sample” in the survey of subjects. In addition, the researchers acknowledge that they can not prove that there is a causal connection between time spent sitting and the shrinking of the brain area. They are therefore planning further studies with larger groups of volunteers. Until the results of these studies are available, US researchers advise people with office jobs to shorten their daily sitting time wherever possible and to incorporate regular physical activity breaks into the office routine. Fitness in the office for prevention Earlier studies have shown the disadvantages of sitting for a long time. So one resulted 2014 published research that prolonged sitting increases the likelihood of developing cancer. A 2015 conducted study showed that frequent travelers have an increased risk of so-called non-alcoholic fatty liver disease. In both cases, the researchers suggested incorporating pauses with physical activity into the sitting times and alternating as often as possible between working while sitting and standing (or while running).
