Runny noses, phlegmy coughs and sweating cause us to lose body fluids, leaving us dehydrated and thirsty.  The obvious response is to reach for a hot drink, but as caffeine is also dehydrating, regular tea or coffee will only exacerbate the problem.

Most herbal teas are caffeine-free, however, allowing you to enjoy your warm drink without the dehydrating side-effects.

Boost your immune system by:

• Drinking more often

Replace moisture lost in coughs and sneezes by drinking regularly throughout the day. It is particularly important to keep hydrated if you have a fever.

• Boosting your vitamin intake

Fruit juices and soups will quench your thirst while supplying essential vitamins.

•  Getting plenty of rest

Studies have shown that deep sleep increases immune functions. Skipping sleep will simply prolong your cold.
