Two Hours of Exercise Cannot Undo Five Days of Sitting
Many people sit for a long time at work, and they wonder if exercising for two hours a week can fix that.
A heart doctor says exercise is very good for you, but it cannot completely erase the harm of sitting too much.
Sitting for many hours can make it harder for your body to control sugar and cholesterol.
It can also slow blood flow and make your heart less healthy.
Exercise helps your heart, your mood, and your muscles, but it is not a magic cure.
The doctor says exercise lowers risk, but it does not remove all risk.
Moving more during the day is also very important.
Taking a short walk or standing up for five minutes every half hour or hour can help.
It is better to replace sitting with activity than to just add exercise.
The best plan is to exercise regularly and move often throughout the day.
Two hours of weekly exercise improves cardiovascular fitness and metabolic health but does not completely undo the effects of prolonged sitting.
Prolonged sitting is an independent risk factor linked to poor blood sugar control, higher cholesterol, reduced circulation, and increased cardiovascular disease risk.
Dr Venkatesh T K says exercise should be seen as risk reduction rather than risk elimination.
Replacing sitting with activity is often more beneficial than adding exercise while keeping total sitting time unchanged.
Experts recommend movement breaks of about five minutes every 30 to 60 minutes and splitting two hours into four 30-minute sessions.
