The European Food Safety Authority (EFSA) recommends an intake of 2.5 litres of water for men and 2.0 litres of water for women per day, via food and drink consumption. Of this, they suggest that 70-80% of the daily water intake should come from drinks, and the remaining 20-30% should come from food.” (http://www.naturalhydrationcouncil.org.uk/hydration-facts/)
Based on the above and that a glass is approx. 250ml, you should aim to drink at least:
- 1750ml (7 cups) to 2000ml (8 cups) men per day
- 1400ml (5.6 cups) to 1600ml (6.4 cups) women per day
- Or a glass of water every 2 to 3 hours (based on a 14 hour day)
- Or 2.5 to 4 glasses during your day at college. (total 625ml to 1000ml)
