Adopting healthy habits can significantly strengthen your immune system, helping you ward off illnesses and maintain overall wellbeing. First, prioritize quality sleep, aiming for 7-9 hours nightly, as it allows your body to repair and regenerate. Second, incorporate regular exercise into your routine, which promotes better circulation of immune cells and reduces inflammation. Third, maintain a balanced diet rich in fruits, vegetables, lean proteins, and whole grains to provide your body with essential nutrients and antioxidants. Fourth, manage stress through techniques like meditation, deep breathing, or yoga, as chronic stress can weaken your immune response.
