Question: i weigh 80kg how much water should i drink?
Answer: The more your weigh, the more water you need to drink. For instance, a healthy person, weighing in at 70 kg and measuring 5 feet 10 inches would be required to drink around 2 litres of water each day. Adult men need to drink more water than adult women, but not by much. The difference is roughly around 0.5 litres.
