Whether you care to listen or not, we’ve all heard we need eight glasses of water a day for good health, and surely you know that the body can’t function without enough water, but did you know that in as little as two hours, you can feel the effects of dehydration - loss of strength, stamina and endurance - in fact, by the time you’re thirsty it’s too late, you’re already heading for cramps, fatigue and dizziness. So make sure you carry enough water and drink some, a little and often - the best way to do this is to have instant access without having to stop and dig out your water bottle.
