    Every year, it’s the same thing: are you afraid of getting sick? To no longer suffer from these seasonal hazards, adopt the advice and tips of Dr Gérald Kierzek now.

    Covid-19, poisoning, colds, bronchiolitis… When the end of the year approaches, viruses take great pleasure in contaminating us. But how can you limit the damage and preserve your health until Christmas? Gérald Kierzek reveals some tips…

    The end of the year, a period that puts our body to the test

    Between the hectic pace of everyday life, the organization of vacations and the rainy weather, it is not uncommon to feel exhausted in the month of November.

    Preparing for the end of year celebrations often involves more stress and less rest: you have to please everyone, think about gifts, the tree and the decoration, while combining personal and professional obligations.

    On a physical level, lack of sleep generally affects productivity and the ability to concentrate. Anxiety can also skyrocket.

    Result ? This state of chronic fatigue can lead to a vicious circle: the weakened body becomes more vulnerable to seasonal viruses.

    Fortunately, getting sick is not inevitable! With a few adjustments and good reflexes, it is possible to protect yourself from the flu, Covid and other infections.

    To counter fatigue, stress and especially seasonal infections, the medical director of Doctissimo has the habit of transforming his routine as soon as the cold arrives.

    • Eat a balanced diet.Choose fresh fruits and vegetables, rich in vitamins, to strengthen your immune system. Avoid overeating which can weaken your natural defenses and fatty, sugary and ultra-processed foods;
    • Stay well hydrated. Drink enough water every day to help your body fight off winter germs”;
    • Maintain regular and sufficient sleep. “Go to bed and get up at set times to allow your body to better fight infections. Avoid screens at least an hour before bed to promote quality sleep”;
    • Manage your stress. “Stress weakens the immune system, so adopt relaxation techniques like reading or stretching before bed. Stay in control of your emotions to stay healthy. Practice self-hypnosis!” ;
    • Stay physically active. “Maintain a regular exercise routine, even during the holiday season. Physical activity strengthens the immune system and helps manage stress.”

    The bonus tip from Doctissimo’s medical director?

    When I feel germs coming (for example in contact with a patient or a sick colleague) I put in place a psycho-immune shield using a virus visualization technique that I mentally repel. It is a mix between positive psychology and NLP, which does not, however, prevent paracetamol!” concludes the medical director of Doctissimo.

    You are now ready to face winter viruses!
