Are you looking for ways to improve your immune system and stay healthy? With the ongoing pandemic and the flu season coming up, it’s essential to keep our immunity in check. A robust immune system can help protect us against viruses, infections, and diseases. In this article, we will discuss various ways to boost your immunity, including healthy habits, foods, and supplements.
Before diving into tips and tricks, let’s understand what immunity is and how it works. Immunity refers to the ability of our body to fight off infections and diseases. Our immune system consists of various organs, cells, and tissues that work together to defend our body against harmful invaders such as viruses, bacteria, and fungi. The immune system recognizes and eliminates these invaders, thus protecting us from infections and diseases.
