You need to drink plenty of fluids to stop you getting dehydrated. The government recommends drinking 6 to 8 glasses every day. This is in addition to the fluid you get from the food you eat. 

All non-alcoholic drinks count, but water, lower fat milk and lower sugar drinks, including tea and coffee, are healthier choices. 

Try to avoid sugary soft and fizzy drinks, as they’re high in calories. They’re also bad for your teeth. 

Even unsweetened fruit juice and smoothies are high in free sugar.

Your combined total of drinks from fruit juice, vegetable juice and smoothies should not be more than 150ml a day, which is a small glass.

Remember to drink more fluids during hot weather or while exercising.
