Love to sit on the sofa for a long time, hurry up and stand up!

Although it sounds a bit alarmist, it is an authoritative science, evidence from the American Cancer Society (ACS), which has recently been published in the American Journal of Epidemiology.


Sedentary and health have formed a common sense: sitting for too long, endangering health. This problem is increasingly plaguing people in modern society, and is closely related to you and me.

With the advancement of technology, the time people sit is greatly increased. Moreover, sedentary time increases with age and the risk of chronic diseases increases.

Scientists have counted that most of the leisure time of the American people is spent on sedentary behavior, such as watching TV. After the Australian people get off work, 90% of their spare time is sedentary, and 53% of sitting time is spent on the screen (such as watching a computer or TV).

Sedentary increases the risk of death in 14 diseases

This American Journal of Epidemiology report brings new evidence of sedentary potential health threats. The researchers collected large data from nearly 128,000 men and women in the American Cancer Society's Health Prevention Study for 21 years, revealing that sedentary prone to increase the fatal risk of the following 14 diseases:


heart disease;



Kidney disease


Chronic obstructive pulmonary disease (COPD);

Lung disease;

Liver disease

Peptic ulcer and other digestive diseases;

Parkinson's Disease;

Alzheimer's disease;

Nervous system disease;

Musculoskeletal disorders.

The risk of death from sedentary increases, depending on the disease, ranging from a 10% increase in cancer death risk to a 60% increased risk of musculoskeletal death.

Sedentary increases the death behind...

Why sitting for a long time will endanger health, it is not very clear. However, the researchers gave some possible explanations.

People who sit on the couch for a long time may have other unhealthy behaviors, such as overeating snacks.

In addition, sitting for a long time, the body's triglycerides, blood sugar, blood pressure and insulin levels will rise, it will also cause obesity-related inflammation.

These abnormal physiological changes may explain the risk of sedentary death from heart disease, liver disease and kidney disease, as well as cancer, diabetes and COPD.

However, sedentary deaths from suicide, Parkinson's disease and Alzheimer's disease, as well as increased risk of neurological and musculoskeletal disorders, are not well understood. The researchers speculate that these diseases alone may exacerbate sedentary.

How to do it away from sedentary hazards?

Since sedentary is harmful, can standing, even standing for a long time, bring long-term health benefits?

In February of this year, researchers at the Mayo Clinic published another study in the European Journal of Preventive Cardiology. For the first time, by reviewing the meta-analysis of large sample studies, the health effects of sedentary and standing were compared.

The conclusion is: Standing can help with health, but it only brings light to moderate health benefits.

Standing for six hours a day for a long time consumes an additional 54 calories, which can be reduced by about 5 pounds a year.

However, for many adults, standing for a long time seems unrealistic, especially for those working in the office.

It seems that people's traditional consciousness believes that standing in other situations is better than sitting. However, it is not desirable to force long standing.

However, for those who need to sit for 12 hours a day, a sedentary time of halving will bring great health benefits.

Take a break of 2 minutes during each hour of exercise, stand up or move a little, which will help improve your body's cholesterol, blood sugar and blood pressure.

The researchers point out that the simple way to stay away from sedentary hazards is to maintain appropriate intermittent activities while we are sitting.
