Introduction
The immune system is the body’s natural defense network that helps protect against harmful substances, germs, and environmental challenges. A strong immune system depends on many factors, including nutrition, sleep, physical activity, stress management, and healthy daily habits.
While no single food, supplement, or lifestyle change can guarantee protection from illness, making consistent healthy choices can support your body’s normal immune functions.
This article explores simple, natural ways to support immune health through everyday habits and balanced lifestyle choices.
