Sedentary lifestyle and children: limit screens, encourage movement

IRIS Prévention
11 November 2026
Children are made to move, run, play. Preserving this movement in front of screens is a health issue for their entire life.

A sedentary lifestyle does not only concern adults. Children and adolescents also spend more and more time sitting, often in front of screens. However, movement habits acquired in childhood influence future health. Promoting activity and limiting a sedentary lifestyle from an early age is a valuable investment.

1. A more sedentary generation

Video games, tablets, television, but also motorized transport and less free play outside: several factors contribute to increasing children's sitting time. This development worries health authorities because it affects a key period of development.

2. Why movement is essential for growing

Physical activity contributes to the child's motor, bone and cognitive development. It contributes to a balanced weight, good sleep and well-being. Conversely, a significant sedentary lifestyle and too much screen time can harm these different plans.

3. Frame screens

Limiting screen time, avoiding screens very early in the morning and before bedtime, and favoring suitable content are some of the guidelines. Screens should not replace active play, interaction, and sleep.

4. Promote daily movement

    • Encourage free and active play, inside and out
    • Prioritize active travel (walking, cycling)
    • Make movement a family and fun moment
    • Set an example by moving yourself

The example of adults is decisive: in an active family, children become active more easily. Moving together is beneficial for everyone.
