Sitting for 2 hours is too greasy! 20 minutes of exercise

Everyone knows that sitting for a long time is a big taboo for health. If you maintain the same posture for a long time, blood will stagnate in the lower limbs, which may cause venous thrombosis. In addition, sitting for long periods of time may cause cardiovascular disease and endanger life. But how much sitting does it take to harm your health? American scholars have found that sitting for two hours straight is equivalent to reducing the positive effects of 20 minutes of exercise to zero.

American research shows that sitting for two hours in a row will offset the cardiopulmonary endurance that can be developed by 20 minutes of exercise.

CBS News quoted a research report published in the Mayo Clinic Bulletin, pointing out that sitting for two hours in a row will offset the cardiopulmonary endurance that can be developed by 20 minutes of exercise. In addition, whether or not you develop an exercise habit, sitting for long periods of time will affect your physical fitness level.

"Sedentary lifestyles can lead to lower physical fitness levels, which can have negative consequences that increase the risk of disease," said study author Dr. Jarett Berry, assistant professor of internal medicine and clinical sciences at UT Southwestern Medical Center, in a statement.

The researchers examined 2,233 individuals aged 12 to 49, observing their cardiorespiratory endurance levels, average daily exercise, and sedentary habits, and excluding the influence of a history of diseases such as heart disease, asthma or stroke. Scholars have found that sitting for two hours in a row is equivalent to wasting the cardiopulmonary endurance that can be developed by exercising for 20 minutes.

Dr. Jarrett Berry believes that in addition to maintaining proper exercise habits, avoiding long periods of sitting in daily life is also an important strategy to improve physical fitness and health.

American scholars suggest that you try to find time to move your body. Even just standing up and stretching is better than sitting for a long time.

Dr. Jacquelyn Kulinski, who participated in the study, said that when sitting for a long time cannot be avoided, we should find ways to keep our body moving. So when you are trapped in the office for a long time, it is good to change your sitting posture from time to time, stand up and stretch, or take a walk while waiting for a call.

The researchers also proposed other tips to help reduce the health threats of prolonged sitting, such as taking a short walk during lunch breaks, using a pedometer to count daily distance walked, taking the stairs instead of the elevator, or being more extreme and replacing office chairs with fitness balls or entire desks with treadmill desks.
