Drink up for better health

Are you dehydrated? How much fluid you need each day depends very much on your body size and level of activity. Bear in mind, too, that hot weather and a tendency to avoid “wet” foods, such as soups, sauces, yoghurt, ice cream and jelly, can increase the need to drink.

The symptoms of dehydration can be hard to spot, but the most common signs include:

  • Thirst – fatigue/lethargy
  • Very dark yellow urine
  • Poor concentration
  • Dizziness
  • Headaches
  • Dry skin
  • Constipation.
  • Irritability

People who have adequate intake of water say they feel fresher and have fewer headaches. So how much is enough? About six to eight glasses of water a day and more in hot weather or after exercise. Less than that and you can become dehydrated, a condition that can lead to dizziness, fatigue, headaches and constipation. Dehydration can also affect a your ability to concentrate: remember the brain is about 78% water, so it needs all the water it can get.
