We know that physical activity is beneficial for the body. We know less that it has a powerful effect on mood. Numerous studies show that regular exercise reduces depressive symptoms, to the point of being recommended as a stand-alone treatment for mild to moderate forms. How can we explain this effect, and how can we benefit from it?
1. A demonstrated effect on mood
Several meta-analyses have shown that regular physical activity significantly reduces depressive symptoms. For mild to moderate depression, its effectiveness is comparable to other treatments. It also acts as prevention and reduces the risk of relapse.
2. How movement affects the brain
Exercise stimulates the release of endorphins and other feel-good molecules, improves cerebral circulation and promotes brain plasticity. It also reduces stress, improves sleep and boosts self-esteem.
| Mechanism | Effect on mood |
|---|---|
| Endorphins, dopamine | Feeling of wellness |
| Stress reduction | Less tension and rumination |
| Better sleep | More stable mood |
| Feeling of accomplishment | Self-esteem reinforced |
3. What activity, at what dose?
No need for performance: regularity is key. We often recommend at least 150 minutes of moderate activity per week, but even a daily walk makes a difference. The main thing is to choose an activity that you enjoy, to stick with it over time.
- Walking, swimming, cycling, dancing: all movement counts
- Aim for regularity rather than intensity
- Move outside and with others when possible
4. A complement, not a substitute
Physical activity is a valuable ally, but it does not replace medical care in cases of moderate to severe depression. It is part of a global approach, alongside other treatments.
Starting small, without feeling guilty about the days you don't have, is the best way to establish a habit that protects your mood in the long term.
In the event of persistent discomfort, this lever complements monitoring by a health professional.
