Our modern lifestyles make us spend more and more time sitting: at work, on transport, in front of screens. This sedentary lifestyle, long confused with a simple lack of exercise, is now recognized as a risk factor in its own right for health. Understanding this “silent evil” is the first step to taking action.
1. What is a sedentary lifestyle?
Sedentary lifestyle refers to time spent sitting or lying down during periods of wakefulness, with low energy expenditure. It is distinguished from physical inactivity, which is the lack of activity. You can thus be active (play sports) and sedentary (stay seated the rest of the time).
2. A risk independent of physical activity
This is the key point: sitting for a long time is detrimental to health even in people who play sports. A daily session does not completely compensate for hours of immobility. A sedentary lifestyle acts through its own mechanisms, independently of exercise.
| Notion | Definition |
|---|---|
| Sedentary | Sitting time, low spending |
| Physical inactivity | Lack of activity |
| Physical activity | Any body movement |
3. Health effects
A significant sedentary lifestyle is associated with an increased risk of cardiovascular disease, type 2 diabetes, excess weight and certain cancers. It also influences metabolism, circulation and even mood. Its effects accumulate with time spent immobile.
4. Good news: it is easily reduced
Unlike other risk factors, a sedentary lifestyle can be combatted with simple actions: getting up regularly, walking, breaking up long periods of sitting. Every interruption counts, no matter how short. The challenge is not to move more intensely, but to stay less still.
- Get up and move around every 30 minutes
- Split up long periods of sitting
- Prioritize active movement when possible
Reducing your sedentary lifestyle is a health lever accessible to all, complementary to physical activity.
