This detailed guide explains the side effects of long sitting, why it is dangerous, and most importantly, how to prevent it.
What Is Long Sitting or Sedentary Lifestyle?
Long sitting refers to staying seated for extended periods with little or no movement. A sedentary lifestyle means low physical activity throughout the day.

If you sit for more than 6 to 8 hours daily, you are considered to have a sedentary lifestyle.
