Glugging back glasses of H2O can do more than just quench your thirst. Staying well hydrated is vital for health, but most of us aren’t drinking the recommended six to eight glasses (around 1.2 L) a day.
While drinking water can help stave off everything from headaches to energy slumps, can we ever drink too much? Here’s what you need to know.

You may lose weight
Drinking more water can boost weight loss by slightly increasing metabolism, says Dietician Lola Biggs. Heading out for a meal? Have a glass half an hour before you eat – it can help you feel fuller so you consume fewer kilojoules. What’s more, drinking water regularly can reduce bloating, as it prevents constipation and water retention – caused by dehydration.

It could disturb sleep
‘One of the leading causes of interrupted sleep is too many nightly trips to the bathroom,’ says Lola. ‘If you up your water intake massively, it’s expected that your kidneys will respond by increased urgency and frequency of toilet visits.’ Want a more restful slumber? Limit drinking at least an hour before bed.
Your energy levels will increase
Cells are responsible for taking nutrients from food and converting them into energy. But to function efficiently, they require optimum hydration’, says Lola. Even being mildly dehydrated can affect mood, energy levels and ability to think clearly, according to studies carried out at the University of Connecticut’s Human Performance Laboratory. Next time that afternoon slump hits, swap a biscuit for some water.
You might feel thirstier
Yes, really! ‘Our body likes to act and adapt to new set points,’ says Lola. If you start drinking lots more water, kidney function and hormones start recalibrating and become more efficient at handling the higher water volume. Therefore, you might find the more you drink, the more your body craves. ‘Increasing water intake slowly, consistently and steadily is key,’ adds Lola.

It may improve skin health
Dehydration can take its toll on your skin, but regularly drinking water can help keep it looking clear, supple and healthy, says Lola. Water helps flush out toxins, leaving our skin more able to perform its normal functions, such as maintaining
a protective barrier against infection, microorganisms and allergens, preventing loss of moisture and reducing the harmful effects of UV radiation.
Hydrate the right way
Water, milk, juices, tea, coffee and even food (such as peppers, celery, oranges and strawberries) all count towards your total fluid intake. Sip gradually through the day and don’t overdo it. The US Centers for Disease Control and Prevention advises against drinking more than 1.4 L of water in an hour, as it can reduce salt concentration in your blood to critical levels.
