It is important to drink little and often to keep hydration topped up every hour! It isn't adviseable to drink it all in one go! It is best to sip water through the day and never drink more than 2 pints in one hour. Do not excede 6 pints in any day. If you are a runner or professional athlete then you may need to trust your judgement and drink more than that but never excede 6 pints, but on average, 4 pints (or 2 litres) of water per day is recommended for the average person.
You also get water through food. Some fruits and vegetables contain a lot of water, such as watermelon and lettuce. How much water do you need to drink every day? A common recommendation is to drink six or eight 8-ounce glasses of water or other fluid every day. But some adults may need more or less, depending on how healthy they are, how much they exercise, and how hot and dry the climate is. You may sometimes need to drink more water than usual if you: Exercise intensely, especially in a hot climate.
