With the return of colds, flu, and other seasonal infections, strengthening one's natural defenses becomes a key issue during the winter months. While not promising absolute protection, certain dietary choices and lifestyle habits can help the body better resist viral attacks, provided they are addressed proactively.
Experts emphasize the importance of a rich and varied diet to support the immune system. Citrus fruits, green vegetables, oily fish, and seafood provide essential vitamins and trace elements, such as vitamin C, vitamin D, vitamin A, and zinc, which are involved in the production and activation of immune cells.
Plants, light and lifestyle: complementary levers
Beyond diet, certain natural substances like propolis or echinacea are frequently cited for their immune-boosting properties, but should be used with discernment and medical advice. Daily exposure to natural light also plays an often-overlooked role, as do sleep and moderate physical activity.
However, health authorities warn against miracle supplements, particularly vitamin C tablets, whose effectiveness against colds has not been proven. It's better to focus on a balanced diet, simple hygiene practices, and a suitable routine to get through winter with a stronger immune system.
