A study suggests that people who drink more water seem to live longer and develop fewer chronic diseases. It found that adults with higher levels of serum sodium – which go up when fluid intake goes down – were more likely to die younger.
The NHS recommends that you drink six to eight mugs a day. Good hydration can also help prevent urinary tract infections, headaches, constipation and other conditions.
However, the study found that the amount of water that people need varies widely. Daily averages ranged from as little as one litre per day to six litres, which included water from other drinks like tea and coffee, and also water in food.
Your water requirement depends on temperature, sex and levels of physical activity. For example, A 20-year-old man, weighing 11 stone living in a climate at 10C would need around 3.2 litres per day whereas a nine stone woman would need 2.7 litres.
Normally, your body will trigger thirst when it needs more fluid and you will urinate any surplus, although if you drink excessive amounts of water, it can be dangerous.
