Drink plenty of water every day!
Hydration is so important! How much water should we drink?
To stay healthy, it's important to replace the fluid we lose when we breathe, sweat or go to the toilet. We get some fluid from our food but most comes from drinks.
The European Food Safety Authority recommends that women should drink about 1.6 litres of fluid and men should drink about 2.0 liters of fluid per day. That's about eight glasses of 200ml each for a woman, and 10 glasses of 200ml each for a man. This also depends on the size of the person, the temperature and how active anyone is.
All drinks count, including hot drinks such as tea and coffee, but water, milk and fruit juices are the healthiest. It is best to avoid alcoholic drinks.
Try to avoid sugary, soft and fizzy drinks that can be high in added sugars as these can also be high in calories and bad for teeth.
Signs of dehydration
When our bodies don't have enough water, we are said to be dehydrated.
One of the first signs of dehydration is feeling thirsty.
If you think you may not be getting enough fluids, check whether you have any of these other common signs of dehydration:
• dark urine and not passing much urine when you go to the toilet
• headaches
• lack of energy  
• feeling lightheaded
