Winter brings cozy sweaters, steaming cups of tea, and the joy of festive gatherings — but it also comes with sniffles, colds, and seasonal infections. As temperatures drop, your body works overtime to stay warm and fight off viruses. The good news? You can naturally strengthen your immune system just by eating the right foods.
Here’s a complete guide to winter immunity-boosting foods that help your body stay strong, energetic, and healthy all season long.
