📰 These serious and deadly consequences of sitting too long

Our lives are no more sedentary than those of our grandparents: we spend more and more time sitting. In recent years, various stakeholders have argued that this habit can have negative consequences health (Health is a state of complete physical, mental and social well-being and…).

Many the media (We call media non-personal means of disseminating information (press, radio, etc.) notably echoed these concerns ( here and here ). Some organizations go so far as to compare it to sitting cigarettes (Smoking is the act of consuming tobacco, a product made from it…): one study even found 600 press articles making this comparison between 2012 and 2016 (“is sitting the new smoking?”).

Effects of sitting on health

Over the past decade, few studies have actually investigated this question. For example, in 2012, a British team reviewed 18 studies and concluded that “sedentary” behaviors were associated with an increased risk of mental illness. Type 2 diabetes (This article is about “type 2 diabetes”, a form of diabetes…)cardiovascular disease and death from any cause.

Another study specifically from 2015to listen (In a sailboat, the sheet is the string used to adjust the angle of the sail…) TV – a activity (The term activity can refer to a profession.) usually done in a seated position—noted that “long” listening (defined as an increase of 2 hours per day) over 14 years was associated with a higher risk of death.

Finally, according to a Swedish occupational health study published in 2021, people who sit all the time at work say they feel less healthy and experience more pain in their backs. the neck (The neck is the region of the body between the head and the rest of the body…) and the horse back (In anatomy, it is the back in vertebrates, including humans…).

Of course, the effect of sitting depends on it time (Time, by man… who is there the past (The past is above all a concept of time: it consists of all…). The data (In information technology (IT), data is an elementary description, often…) suggests the negative consequences of sitting for more than 7 hours per head day (A day or day is the interval between sunrise and sunset; it…)Explain Canadian and Australian researchers who reviewed the literature in 2018 scientist (A scientist dedicated to the study of a science or sciences and…) the end.

What is a sedentary lifestyle?

However, as recently as 2006, an international team of researchers questioned the fact that different studies on sedentary lifestyles did not always use the same definitions to describe sitting, making interpretation of results difficult.

The problem starts with it definition (A definition is a conversation that tells what something is or what a name means. So…) even “sitting”. The Canadian and Australian researchers cited above thus recall that sedentary behaviors include not only the sitting position, but also all awake behaviors characterized by “low energy consumption.” This applies, for example, to the standing position of people offered at checkouts, e.g. everything (The whole, understood as the whole of what exists, is often interpreted as the world or…) many additional problems, as the 2006 study already mentioned.

Although the researchers included time spent in front of the TV in the sitting hours, a 2006 paper argued that this could have skewed the results. This opinion is also shared by Australian researchers who tried to determine whether the fact exists in 2016 to pass (The Passer breed was created by the French zoologist Mathurin Jacques…) too much sitting time increases the risk of premature death. they celebrate by looking television (Television is the transmission of cable or radio waves, images or…). associated with several confounding and less healthy factors such as snacking.

Danger: to sit or not to move?

These Australian researchers evaluated eight systematic reviews (i.e. eight summaries of studies) based on the Bradford Hill criteria (nine criteria widely used in epidemiology) to assess whether there was a causal relationship. Their conclusion is that it will nice (Named in honor of inventor Alexander Graham Bell, bel is the union of …) and indeed a “strong” association between time spent sitting and mortality, particularly because of the stability of this association over time. The authors note that this association was only observed in people who were not very active, which brings us back to the notion of a “sedentary lifestyle.”

A 2006 paper also noted that the relationship between time spent sitting and mortality appears to depend on a person’s level of activity.physical activity (Physical activity includes both daily life, at home, and physical exercise.) persons. Similarly, two studies conducted in 2014 and 2015 found that the risks associated with sitting time were higher in people who were not physically active.

According to these researchers, we therefore need to ask ourselves whether sitting actually has consequences independent of general lack of activity. physical (Physics (from Greek φυσις, nature) etymologically…). Australian researchers disagree: they note that it is possible to be very active in general by spending a lot of time sitting.

Replace idle time with active time?

A third study was recently conducted country (Country comes from the Latin pagus, which designates a territorial and tribal division…) concluded that reducing sitting time will not be enough to improve people’s health absolutely (Completion or fully automatic, or anglicism completion or…) inactive. In other words, replacing sitting time with standing time will not be enough: it would be better walk (A walk (the pleonasm walk is also often used) is a…) or by stronger activity.

a published study Lancet In 2016, in turn, he decided to go from 60 to 75 minute (The original form of the document: Law: minute one…is the original) It eliminated the risk of sitting for 8 hours or more per day with physical activity. In other words, according to the first author of the article, a hour (Time is the unit of measure 🙂 physical activity would compensate for 8 hours of inactivity.

A 2006 study already suggested this: rather than recommending that people spend less time sitting, we should encourage them to move more, regardless of the intensity of the activity.


Spending a lot of time sitting is actually associated with an increased risk of death. However, this association is likely due to the lack of physical activity rather than the task itself.
