The immune system is a complex network of cells, organs and tissues that work in tandem to protect the body from infection.

Don’t neglect proven health advice: Washing your hands, avoiding contact with infected and not touching your face are all important when it comes to protecting yourself from viral illnesses.

Eat a balanced diet: Include these foods which are touted for their immune-boosting properties – Citrus fruits, Red bell peppers, Broccoli, Garlic, Ginger, Spinach, Yogurts with active cultures, Almonds, Turmeric, Green tea, Papaya, Kiwi, Poultry, Sunflower seeds and Shellfish.

Stay active: Physical activity may help flush bacteria out of the lungs and airways. This may reduce your chance of getting a cold, flu, or other illness.

Lower your stress: Your body does a better job fighting off illness and healing wounds when it’s not under stress.

Improve your sleep habits: The sweet spot for sleep is six to seven hours a night.

Avoid excessive alcohol consumption: It is recommend that alcohol should be consumed only in moderation – up to one drink per day.

Recommended to quit smoking: Smokers are much more likely to contract respiratory viral illnesses due to their weak lung function.

Check your Vitamin D level: Consider having your Vitamin D level checked.
