Your immune system is your body’s natural defense against illness, infections, and harmful bacteria. A strong immune system doesn’t mean you’ll never get sick, but it does help your body respond more effectively and recover faster. The good news is that you don’t need expensive supplements or complicated routines to support it—simple, consistent lifestyle habits make the biggest difference.
This guide explains practical and natural ways to strengthen your immune system and improve overall health.
