Boost your immunity naturally: prevent colds and flu-like symptoms

Every winter, our immunity is put to the test.

Colds, nasopharyngitis, flu-like symptoms, sore throats, and stuffy noses are among the most common seasonal disorders, and boosting immunity naturally plays an essential role in fighting them off. Although these infections are usually mild, they can disrupt daily life for several days and, in some vulnerable individuals, leading to complications.

In France, the fall and winter months are marked by increased circulation of respiratory viruses, particularly influenza viruses, rhinoviruses, and seasonal coronaviruses. Adopting preventive measures and supporting your natural defenses is therefore essential for getting through the winter in good health.

Colds and flu in France: some key figures

According to Santé publique France, seasonal flu affects between 2 and 6 million people each year in France, depending on the intensity of the epidemic season.

During winter periods, health authorities observe:

a significant increase in consultations in private practice,
an increase in hospitalizations among people aged 65 and over,
concurrent circulation of other respiratory viruses responsible for colds and nasopharyngitis.

Even outside of flu season, winter respiratory infections remain one of the leading reasons for medical consultations, particularly among children and young adults.

Why is immunity more important during the winter months?

Our immune system is the first line of defense against infectious agents. In winter, several factors can weaken it:

decreased sun exposure (affecting vitamin D status),
accumulated fatigue, linked to lifestyle, lack of rest,
more promiscuity in enclosed spaces,
colder, drier air irritating the respiratory mucous membranes.

When the mucous membranes in the nose and throat are weakened, viruses can enter the body more easily.

👉 Objective : take action before symptoms appear, and at the first signs (runny nose, scratchy throat, fatigue).

Preventing winter infections: healthy habits

We have all become familiar with them since the COVID pandemic began. Protective measures are systematically recommended by the authorities and involve simple steps that help reduce the risk of infection:

Wash your hands regularly for at least 30 seconds. In the context of winter infections, this should be done at least before preparing meals or eating, after blowing your nose, and after sneezing or coughing into your hand.
Daily ventilation of rooms to reduce the concentration of microbes,
Adequate hydration,
Balanced diet rich in vitamins and minerals,
Regular nasal hygiene, especially during epidemic periods.
Wearing a mask in case of infection, to avoid becoming infected but also to avoid transmitting the disease, particularly to vulnerable people.

Unusual fact: A microbe can be propelled up to 6 meters when someone sneezes!
