"Sedentary" pay attention!
New study: sitting for 8 hours a day, the risk of stroke is 7 times higher
In recent years, despite many warnings that sitting for long periods of time is harmful to health, most people are still the same.
According to foreign media reports, a new study published by the American Heart Association pointed out that among people under the age of 60, those who sit for 8 hours a day without exercising have a higher risk of stroke than those who exercise for at least 10 minutes a day and sit soon after 7 Times.
According to reports, researchers tracked and analyzed the health information of 143,000 adults aged 40 and over who had no previous stroke history. The average follow-up study lasted 9.4 years.
It was found that 2,965 strokes occurred among these people, 90% of which were ischemic strokes.
Ischemic stroke is the most common type of stroke. It occurs when the blood vessels supplying the brain are blocked.
If the stroke cannot be treated in time, the brain cells in the corresponding area may die due to lack of oxygen.
The study found that those who exercise for at least 10 minutes a day and sit for less than 4 hours have a stroke risk 7 times lower than those who sit for 8 hours without exercising.
What is the relationship between sedentary and the cause of stroke?
The lead author of the study, Dr. Reid Jondy, a clinical scholar at McMaster University in Canada, explained: “Sitting for a long time is believed to affect glucose, lipid metabolism and blood flow, and increase inflammation in the body. These changes will affect the body over time. Human blood vessels produce side effects, which increase the risk of heart attack and stroke."
According to foreign media reports, sitting for a long time is considered as harmful to health as smoking, and it also increases the risk of obesity, herniated discs, tension headaches and other physical problems.
In fact, maintaining a similar relatively static posture for a long period of time while awake is harmful to health.
How can we reduce the risk of stroke?
Kerry Stewart, a professor of pharmacy at Johns Hopkins University School of Medicine in the United States, pointed out that while reducing sitting time, it is necessary to increase physical activity.
You can start by standing more and sitting less, and at the same time make some small changes in your daily life, such as climbing stairs instead of taking the elevator.
According to the relevant recommendations of the American Heart Association, adults should perform at least 150 minutes of moderate-intensity physical activity each week, and each time should last more than 10 minutes.
Moderate exercise refers to exercises that can increase your heart rate and make people sweat, such as brisk walking or cycling.
In addition, Qiongdi also added that it is not just to reduce the time of sedentary and inactivity, because "increasing physical activity is only one of the important factors in reducing the risk of stroke. It should also be combined with nutritious diet, smoking cessation, and diagnosis and treatment of high blood pressure and diabetes. means."
