A strong immune system doesn't come from a single miracle pill — it's built through consistent, healthy daily habits. Here are 5 science-backed habits you can start today to give your body the defense it deserves:

1. Eat a Rainbow of Fruits & Vegetables: Colorful produce is packed with vitamins, minerals, and antioxidants. Aim for at least 5 servings a day. Citrus fruits, berries, spinach, and bell peppers are immunity superstars.

2. Get 7–8 Hours of Quality Sleep: During sleep, your body produces cytokines — proteins that fight infection and inflammation. Chronic sleep deprivation weakens your immune response significantly.

3. Stay Hydrated: Water helps carry oxygen to your cells and flushes toxins from the body. Aim for 8 glasses a day, and consider warm water with lemon in the morning for an extra detox boost.

4. Exercise Regularly: Moderate exercise — like brisk walking, cycling, or yoga — improves circulation and helps immune cells move through the body more effectively. Just 30 minutes a day makes a big difference.

5. Manage Stress: Chronic stress releases cortisol, which suppresses your immune system. Practice deep breathing, meditation, or simply spend time in nature to keep stress levels in check.
