How much do you know about hydration?

Do you know?...
  1. Its not really necessary to drink t least eight glasses of water per day.There's no evidence for the oft-repeated assertion that people need at least eight glasses of water per day. Most people get adequate hydration without "purposeful drinking" of fluids for hydration.
  2. 20% of the average person's daily water intake is from food. An apple is 84% water. Bananas are 74% water. Broccoli is 91% water. Even foods that you might not think of as particularly moist.
  3.  Exercise in hot humid conditions can cause significant dehydration in as quickly as 30mins.
  4. While exercising most people should break for water every 20mins.
  5. Out of alcohol, coffee and sugar-sweetened soda, alcohol is considered to be the most dehydrating drink.
  6. The average adult loses 10 cups of water every day through natural bodily functions.
  7. You may be dehydrated if your urine looks like concentrated apple juice.
  8. Drinking water can help you lose weight.
  9. You can drink much water when exercising. The International Marathon Medical Directors Association recommends that athletes drink no more than 31 ounces of water per hour during extended exercise. 
  10. 'Thirst' is an early warning sign of dehydration, but you should not rely on thirst alone. Other early signs are: fatigue, flushed skin, faster breathing and pulse rate, and decreased exercise capacity. Later signs include weakness, dizziness, and labored breathing.  
  11.  Water is usually as good for rehydration as sports drinks that contain electrolytes.
  12.  The human body is mostly water: about 55% to 75%, on average (and depending on how well hydrated you are). That's about 10 to 12 gallons of water in your body!
    Water makes up about 83% of blood, 73% of muscles, 25% of body fat, and 22% of bones.
Stay hydrated..
