how much water can a person safely drink in a day
Eight glasses a day? We've been told we need to drink at least eight glasses of water a day, but Taylor says there's no scientific evidence to support this. Health professionals agree men's bodies need around 2.6 litres and women's around 2.1 litres of water a day (pretty much eight glasses a day). But it turns out you get some of this from other drinks and food, Taylor says. Approximately four glasses of water, or a litre a day, is obtained from the food that we eat.
