We all heard about the dangers of a sedentary lifestyle. It can hardly be called useful for our entire body. However, if earlier the dangers of a sedentary lifestyle were only spoken of as a factor provoking the development of a number of diseases, then a fresh report by Norwegian scientists, theses from which were recently announced at the ESC 2019 World Cardiology Congress, makes us look at the problem differently. After all, a sedentary lifestyle can quickly lead to premature death.
How does a sedentary lifestyle affect health?
Prior to this, the European Society of Cardiology atFor more than 20 years, it has been found out how physical activity affects the likelihood of death from various causes, and the author of the new work, Dr. Trine Moholdt, stated that most of the researchers who participated in these studies made a rather gross mistake - they interviewed their subjects about how intense they were exercise, only once for the entire period, after which they simply continued to monitor the state of health.
The goal of the new work was toevaluate how changes in physical activity over 22 years were associated with subsequent death from any causes and diseases, because physical activity is part of our habits that change in many people over time. Therefore, it is crucial to understand how such changes are associated with the risk of future death. The authors invited all interested residents of Norway aged 20 years and older to take part in the new work. As a result, 23,146 men and women were selected, the survey was conducted 3 times: in 1984-1986, 1995-1997 and 2006-2008, respectively. Each time people were asked about their frequency and duration of physical activity in their free time. Physical activity was classified as inactive, moderate (less than two hours per week) and high (two or more hours per week). Participants were divided into groups according to their level of activity in each survey.
Further, the obtained data were compared with information onmortality rate at the end of 2013. The risk of death in each group of physical activity was compared with the reference group (those who reported a high level of physical activity during both examinations). Scientists did not disregard factors such as body mass index, age, gender, smoking, level of education and blood pressure.

As a result, compared with the control group,people who were inactive in 1984-1986 and 2006-2008 had a 2.7 times higher probability of dying from cardiovascular disease and a 2 times higher risk of dying from other causes associated with a sedentary lifestyle. In persons with moderate activity at both time points, the risk of death from other causes and from cardiovascular diseases was increased by 60% and 90%, respectively, in comparison with the control group.
Dr. Mocholdt noted that there are clearrecommendations on the number of exercises that adults should do to “optimize their health”. According to the conclusion of the scientist, these figures are only 150 minutes of moderate physical activity or 75 minutes of anaerobic exercise (running, swimming) per week.

The important point here is that the levelsphysical activity even lower than recommended will not give health benefits. Physical activity is a more important indicator than the number of exercises. That is, no matter how fast you run. The important thing is how long you do it.
As for those who “changed categories” betweentests, that is, people who switched from an inactive to an active lifestyle had a mortality risk significantly lower than those who remained at the same level of physical activity.
