7. Get plenty of sleep.



Not getting enough sleep for even one night can do plenty of damage to your immunity. If you're feeling sniffly and get 8 to 9 hours of rest, you might just wake up fine in the morning, but if you don't get enough sleep, you'll definitely wake up with a cold!

8. Load up on vitamins and proteins.




Vitamins boost your immunity, so eat plenty of fruits and veggies. Citrus fruits are a good idea, since they are loaded with Vitamin C, the main vitamin behind immunity. Lack of protein also hurts your immunity, so try to eat a little more protein for a few days to shore up your defences.

9. Drink lemon tea with honey and cinnamon.




Lemon is loaded with Vitamin C, while honey and cinnamon are a powerful antibacterial and antiviral combination.

10. Avoid smoking and drinking.



Studies show that smokers get colds much more frequently than non-smokers, since the chemicals in the smoke affect immunity. Alcohol also hurts your immunity, so avoid drinking if you're coming down with a cold. Drinking also prevents you from getting restful sleep, and sleep is important for immunity.
