Is 8 your magic number?  What do I mean by that?  I am not sure when the advise for how much water you need to drink each day come into being.  What I can tell you is the AVERAGE rule of thumb for adults has been to promote 8 ounces (250 ml) X 8 glasses = 64 ounces OR 2 Liters.  How come?  During the course of an average day, adult humans lose 2 to 2.5 liters of water.  For maintaining health, its been recommended we replace what’s been lost.  But is that number right for all?  Hard to say as it depends on your age, your diet – its been show that if you are on a high protein diet you need more water, activity level, or if you are ill .  The best way to know is to check in with yourself.  Here is what I mean:

Signs you might not be getting enough water:   


Suggest you consume at least 8 X 8 glasses = 64 ounces OR 2 Liters


  • thirst
  • headaches
  • lethargy
  • mood changes and slow responses
  • dry nasal passages
  • dry or cracked lips
  • dark-colored urine
  • weakness
  • tiredness

So is 8 your magic number or is it 6 or 10?
