We’ve spoken to healthcare experts to learn about how much water we should be drinking…
Dr Anousheh Alavi is a dental surgeon and scientific affairs manager for Colgate:
“Water is the healthiest thing you can drink – it keeps you hydrated and won’t harm your teeth like fizzy drinks.
Saliva keeps our teeth and gums healthy, and as we produce less when we’re asleep, it’s important to brush your teeth last thing at night. Some medications can also reduce saliva flow but you may not notice, so it’s good to drink plenty of water to keep your mouth hydrated. If you’re inclined to rinse your mouth with water after brushing, spit instead to avoid rinsing away the protective ingredients in toothpaste.”
Sarah West is a freelance nutritionist and health coach:
“While it’s important to drink water regularly and to always drink when you’re thirsty, the amount of water your body requires depends on your weight, level of activity, diet and the temperature and humidity of your environment, so different people have different needs.
A good hydration guide is the colour of your urine. A dark yellow or amber colour usually signals dehydration, while clear or pale yellow means you’re well hydrated.”
Dr Ellie Cannon is a practising GP and Woman’s regular medical columnist:
It is a myth that you have to drink eight glasses of water a day. In a healthy person, even if you drink very little, your kidneys function to correct the lack of fluid. Of course water is preferable to consuming unnecessary calories from sugary drinks or caffeinated drinks, which dehydrate you. We actually get huge amounts of fluid from food, so three or four glasses daily is enough.
