Drink plenty of water

Water is a healthy and cheap choice for quenching your thirst at any time. It has no calories and contains no sugars that can damage teeth. 

Plain tea, fruit tea and coffee (without added sugar) can also be healthy.

If you do not like the taste of plain water, try sparkling water or add a slice of lemon or lime. 

Or heat the water and infuse a tea bag, some coffee or a slice of lemon. 

You could also add some no-added-sugar squash or fruit juice for flavour.

Sports drinks

Sports drinks can be useful when you’re doing high-level endurance sports and need an energy boost.

But they’re no different from any other sugary soft drinks, which means they’re high in calories and contribute to tooth decay. 

Unless you’re taking part in high-level endurance sports, water is the healthier choice and the best way to replace fluids lost through exercise.
