HIT THE DRINK

You’re unlikely to forget to drink water when it’s warm, but during the winter months most people are less inclined to reach for the bottle. Staying hydrated is essential not only for keeping the trillions of cells in your body functioning effectively, but also to encourage the production of saliva – the first line of defence against illness and infection. Saliva contains the antibody immunoglobulin A (IgA), which helps to provide a barrier against pathogens.

If you struggle with water intake, try including more herbal teas and diluted fruit juices, to encourage more hydration.
