6 fun facts about Hydration- It’s more than just water!

  1. Our body is mostly made up of water, it accounts for approximately 50-80% of our body mass; The average person has somewhere between 30-60 litres of water in their system at any one time;
  2. Our body can only last a few days without water, you can last a lot longer without food – but we don’t recommend going without either. Famously, Mahatma Gandhi lasted 21 days without food relying only on sips of water;
  3. Water is an important factor to maintaining good health, wellness and preventing illness. Here are some of the great things water does for us
    • Regulates our Body Temperature;
    • Cushions and Lubricates Joints;
    • Shields our Spinal Cord and Sensitive Tissues;
    • Assists in a healthy Bowel Movement, Urination and Perspiration;
    • Improves Cognitive Health & Mental Health;
    • Assists with Weight Maintenance & Loss
  4. Water is also great for weight loss and weight management; not only does it help keep us feeling full, but contrary to what many believe, water is the only negative calorie substance we regularly consume.  Drinking 1 litre of cold water can burn up to 28 calories, which adds up to approximately 1,700 calories a month if you drink 8 glasses of water a day.
  5. There is the same amount of water on Earth as there was when the Earth was formed. It is possible that the water from your tap could contain molecules that dinosaurs drank – this has nothing to do with nutrition we just think that is super cool.
