Immune defences: good everyday habits
Young children are often ill during their first years in a group setting, and that is normal: their immune system is learning. Here is what really matters day to day, and what is mostly received wisdom.
An immune system in training
A child in a group setting falls ill more often than an adult. It is not a sign of fragility: each mild infection teaches the body to recognise a pathogen and to react faster the next time.
This learning period lasts several years and intensifies when starting nursery or school. The aim is therefore not to avoid every infection, but to give the child the conditions to recover well between episodes.
Sleep, the most underestimated factor
It is during deep sleep that the body devotes the most energy to its defence and repair functions. A child who regularly sleeps less than they need recovers less well.
The commonly used guidelines are around ten to thirteen hours a night between three and five years old, and nine to twelve hours between six and twelve years old, naps included for the youngest. A regular bedtime, even at weekends, counts for more than the length of a single night.
A varied plate rather than a miracle food
No single food makes the difference on its own. Regularity and variety are what count.
Colourful fruit and vegetables provide vitamin C. Vitamin C contributes to the normal function of the immune system. Dairy products, eggs, fish and pulses provide protein, zinc and iron. Zinc contributes to the normal function of the immune system. Varying the colours on the plate remains the simplest way to cover this range without counting.
Moving and going outside, even in winter
Daily physical activity and time spent outdoors are among the habits associated with better general health in children. Cold does not make you ill: it is close contact indoors that helps viruses spread.
One hour of active play a day, split up if needed, remains a realistic and sufficient goal.
And food supplements?
They replace neither a varied diet nor a healthy lifestyle. They can be a top-up when a child's diet is very selective.
Before giving one to a child, ask your doctor or pharmacist. Only they know the context, any ongoing treatment and the real needs.
- Falling ill regularly is normal in young children.
- Regular sleep is the most effective and most overlooked lever.
- No single food makes the difference: variety is what counts.
- A supplement is a top-up, never a solution.
