Why sitting for a long time is bad for your health

To sit on something that most people do well every day, for the office, indoor transport or for the home.

But for the sake of vascular dysfunction, sitting in one place for a long time increases the risk of serious health diseases such as cardiovascular disease and type 2 diabetes.

In 1953, epidemiologist Jeremy Morris discovered that London bus drivers are more likely than bus conductors to develop coronary heart disease.

Demographically (age, gender and income range) two groups of workers are the same, so why say we have a significant difference?

Morris answers: Bus conductors’ jobs require them to stand and not regularly climb the steps of London’s iconic double-decker buses as they sell tickets to passengers while drivers sit for long periods of time.

My ogbonge study has formed the basis for a research on the links between physical activity and coronary health.

Although London bus drivers now work will not reign as bifor again, Morris’s results are more important and important.

Since the Covid-19 pandemic, we don’t see a huge shift towards working from home, but it is likely to increase our collective sitting time.

Without our usual need to collect water from the cooler and move from meeting room to meeting room, it’s easy for five to spend hours sitting at their desk without getting up.

(However, office culture has not already changed our work lives today in the 1980s, when some researchers joked that our species did not become Homo sedens – meaning “sedentary man” – but rather Homo sapiens.)

Prolonged sitting is a form of sedentary behavior characterized by a greatly reduced energy expenditure in a sitting or lying position.

Typical sedentary behaviors including watching TV, playing games, driving and working at a desk.

Sedentary behaviors are associated with a higher risk of cardiovascular disease, type 2 diabetes, and premature mortality, and time spent sitting in particular has been identified as an independent risk factor for a variety of health conditions.

In 2020, the World Health Organization suggested measures to reduce sedentary behavior.

To not allow for a long time a form of sedentary behavior, as they say, signals a greatly reduced expenditure of energy for the sitting or lying position.

There are typical sedentary behaviors, including watching TV, playing games, driving, and working at a desk.

Sedentary behaviors are associated with a higher risk of cardiovascular disease, type 2 diabetes and premature mortality, and time spent sitting, in particular sabi pipo, is identified as an independent risk factor for a number of health conditions.

For 2020, the World Health Organization suggests measures to reduce sedentary behavior.

Since 2010, researchers want to point out sedentary behavior and lack of physical activity. You adapt well to exercise every day, and you still don’t sit for long.

However, the dangers of sedentary behavior are greater for those who do not exercise enough.

For example, sitting for a long time will increase the dysfunction of the blood vessels, especially for the second legs.

According to sabi pipo, the two vascular system is responsible for keeping blood and lymph fluids – and they are part of the immune system – moving through the blood vessels.

David Dunstan, a physiologist for the Deakin University Institute for Physical Activity and Nutrition, Melbourne, Australia, has researched extensively the effects of prolonged sitting and possible interventions.

“Some key to reducing muscle activity is to reduce sitting,” Dunstan said. “If I’m going to sit in a chair, di chair will take all the responsibilities dia.”

The combined effect of reduced muscle activity, lower metabolic demands and gravitational forces can reduce blood flow to the leg muscles, and lead to pooling of blood for both calves.

I know the biomechanics of sitting, the smartness of the legs that usually go to flexion, the fit also reduces blood flow.

Researchers suggest that someone sitting for 120-180 minutes in one place is not healthy.

Reduced biceps muscle activity reduces metabolic demand dia. Metabolic demand is a major determinant of blood flow, so blood flow to both legs is also reduced. The biomechanics of sitting, flexing the legs to accommodate causes blood to pool in both calves – a study of 21 healthy young volunteers found that diac calves grew in girth by nearly 1 cm (0.4 in) per two hours. Dis fit also reduces blood flow.

Normal blood flow provides friction, known as arterial shear stress, against the endothelial cells lining the blood vessel walls. The endothelium does respond to force, and it secretes vasodilators, such as adenosine, prostacyclin, and nitric oxide, but keeps the vessels sufficiently dilated and maintains the vascular system’s ability to self-regulate—what many know as homeostasis.

Reduced blood flow, however, reduces shear stress, and the endothelium produces vasoconstrictors such as endothelin-1 that cause vasoconstriction. In a vicious cycle, vasoconstriction further reduces blood flow and blood pressure rises to keep the blood moving. High blood pressure, or hypertension, is one of the predominant risk factors for cardiovascular disease.

“Date [vascular dysfunction] “In one of the possible mechanisms,” adds Dunstan. “But, the truth, to say that we do not fit precisely the exact mechanisms, and there is the possibility to say that it is also multiple.

Although some underlying mechanisms are hypothetical, recent studies support the theory. A study of 16 young, healthy men found that sitting for three hours will increase blood flow to the legs, peripheral vascular resistance, diastolic blood pressure and leg circumference. Another study found that blood pressure may increase with time spent sitting without interruption. Researchers generally agree that 120-180 minutes of uninterrupted sitting and maybe a threshold, we can say that you probably don’t spend a lot of time in a sedentary position, but vascular dysfunction generally increases the amount of time you spend sitting.

Sitting for a long period of time can expect you to eat high-fat foods that are harmful.

Also, the musculoskeletal system is likely to be unaffected. Prolonged sitting contributes to reduced muscle strength, lower bone density, and increased total and visceral fat for adipose tissue.

Furthermore, prolonged sitting is associated with physical discomfort, work stress and higher depression, and even pressure ulcers.

Dunstan, who also specializes in type 2 diabetes research, also says that being sedentary increases postprandial eating to increase blood glucose and insulin. Impaired insulin sensitivity and impaired blood vessel function both contribute to a higher risk of cardiovascular disease and type 2 diabetes.

Pipo will become more sedentary, to be encouraged by society. Since cans are more efficient, we don’t need to move as much – Benjamin Gardner

With all the known potential consequences, why can we say we still don’t sit for long—and how do we adapt to breaking the habit?

“I think Pipo wants to become more sedentary because society encourages it,” he said.

Benjamin Gardner, a social psychologist specializing in all common behaviors for the University of Surrey, doing research why do I sit for so long say; “You can’t say someone pushed on purpose. Just say the cans are now more efficient, we don’t need to move as much.”

For 2018, Gardner and colleagues found that encouraging Pipo to stand up for meetings presents unique social barriers.

“We encourage Pipo to try this [standing up] for three different meetings, and we interview each one of them to find out how they do it, and the findings shock us,” Gardner said. “For a formal meeting, they think to say how they do it.”

Just getting up often to take a light walk or climb a few stairs is also helpful.

The fit of wearable technology also reminds us of movement. Wearable devices such as call pacemakers provide 24-hour data on individual behavior patterns, including sitting, standing, sleeping and exercise, according to a promising new study.

As Dunstan bin pointed out earlier, if you can’t allow optimal times adjusted for sitting and standing, these devices go to send automatic reminder alerts whenever you sit for a long time.

However, the use of technology is not without flaws, as some pipe fits are frustrated by the jam or do not send messages from them.

Above all, Gardner and colleagues encourage moving more frequently between sitting and standing positions.

The premise of breaking up sitting time just by standing up is simple, but you get significant health benefits, especially for low-activity individuals.

For wheelchair users or mobility limitations, specific, tailored exercises can help.

For many people, sedentary behavior is difficult to avoid for the sake of modern life and work. But even small changes to your routine – if you stretch more, move around or stand up to make a cup of tea – help break your sedentary habit.
