Dr Mark Porter debunks some myths about how much water we need to drink.
Q: I constantly read that we should all try to drink two to three litres of water a day. What is your view?
A: This widely quoted figure is largely based on marketing hype (often from bottled water suppliers) rather than real science. The average adult typically needs only around 1.5 litres of water a day (more in hot weather and if you exercise regularly) and it doesn’t have to be direct from the tap or bottled. Tea, most types of coffee, juices, soft drinks and the water in your food all count towards this total.
