Drinking sufficient water is arguably one of the most important activities for health that we do each day. However, sometimes we aren’t drinking enough which may lead to impaired performance.
The human body is mainly made up of water (about 70% in an adult and 80% in children). Similar to calories, the right amount of water to be drunk is dictated by the balance between the intake and the losses.
So how much water should I be drinking?
The daily recommendations are 8 glasses of water a day (2-2.5Litres).
- This amount may increase for reasons such hot weather, illness or exercise.
- Water, milk and sugar free drinks can be counted as a glass of ‘water’. However, it is best to try to have 8 glasses of water and other drinks on top of this.
- Tea and coffee do not count as they are mild diuretics, meaning they encourage you to urinate more frequently. Although a few cups a day is unlikely to cause dehydration it may increase your bathroom breaks!
Dehydration can lead to
- Headaches, dizziness and diffiulty concentrating
- Feeling tired
- Dry eyes and mouth
- Reduced mental performance
- Reduced endurance, power and strength performance during exercise
- Dark coloured urine (a good indicator you should drink more water)
If you feel thirsty your body is warning you to drink something to prevent becoming dehydrated. It is best to try and avoid getting thirsty!
