Dark green leafy vegetables, like kale, greens and spinach, Vitamin C and E all help your body fight infections and boost your immune system.
2. Don't be a sinner.
Smoking and drinking may be enjoyable for many of us, but they won't help you fight off an infection.
Smoking means you're more likely to get a sore throat, while wine and beer will attack your liver and it will take longer for any germs to leave the body.
3. Chill out.
Stress is a huge factor in staying healthy, so if you can cut out the things that get you all knotted up, then you're less likely to catch a cold.
