Lancet: Why does sitting for a long time easily lead to depression?

In modern society, factors such as fast-paced life, high work pressure, and less entertainment time cause anxiety and negative emotions to spread like weeds

Depression, a mental illness, is becoming more and more common in the general population

There are two main reasons for weight gain during the holidays

Less exercise will not only lead to obesity, but also affect mental health

A study published in the internationally authoritative medical journal "The Lancet Psychiatry" shows that sitting for a long time increases the risk of depression in young people

Identifying variable risk factors is the key to reducing the prevalence of depression in adolescents

Questionnaire survey data indicate that physical activity and sedentary behavior may be related to the occurrence of depressive symptoms in adolescents

Researchers collected data on 4257 adolescents

Therefore, data integrity, contrast, and reliability are high

Accelerometers show that these teenagers are either active or sedentary

At the same time, the researchers also recorded whether 4257 adolescents had depressive symptoms (such as low mood, lack of fun, lack of concentration, etc.

Between the ages of 12 and 16 years, overall physical activity decreased, mainly due to decreased light activity (from an average of 5 hours and 26 minutes to 4 hours and 5 minutes) and increased sedentary behavior (from an average of 7 hours)

Researchers found that at the age of 12, 14, and 16, if you sit for 60 minutes a day, the risk of depression by the age of 18 will increase by 11.

In addition, in these three age groups, sedentary adolescents have a 28.

The lead author of the study, Aaron Candola, said: "Over the years, the sedentary time of young people has been steadily increasing.

Mental health also has an impact

Professor Joseph Hayes, the corresponding author of the study, said: “Slight exercise may be particularly useful because it does not require much effort and is easily integrated into the daily lives of most young people

Schools can integrate light activities into students’ daily lives

All in all, this study by University College London in the United Kingdom shows that the amount of activity during adolescence (12-16 years) is negatively correlated with the risk of depression at the age of 18

Sitting for a long time will increase the risk of depression in adolescents to a certain extent
