A healthy immune system stands between our bodies and infection from bacteria and viruses. During flu season, it’s especially important to keep your immune system in shape. Here’s how:
• Hit the hay. Research shows that lack of sleep leaves you more vulnerable to viruses. Aim for seven to eight hours a night.
• Keep moving. Regular physical activity helps your body fight infection. Experts recommend two-and-a-half to five hours of moderate exercise weekly.
• Eat the right stuff. A variety of nutrient-rich foods will keep your immune system operating at its peak. Include whole grains, beans and fruits and vegetables. Fish and dairy products fortified with vitamin D may be especially good for boosting immunity.
• Take it easy. Stress weakens your ability to ward off disease. Try relaxation techniques like yoga, meditation, which research shows can help keep your immune system strong
