Why you need to drink more water NOW: Doctor reveals exactly what happens to your body when you consume two litres every day

As the human body consists of nearly 60 per cent water, it is essential to maintain health and wellbeing by drinking at least two litres of water each day.

Sydney general practitioner Dr Dasha Fielder told FEMAIL most adults should aim to drink between 2.5 to three litres in order to maintain optimum hydration.

Dr Fielder said drinking water will help hydrate the kidneys, improve digestion and gut health, rejuvenate the skin and avoid feeling fatigued.

‘We lose a lot of water by drinking caffeinated drinks, such as teas and coffees, and overnight while sleeping – so we need to replenish this throughout the day,’ she said.

Maintain kidney health and flush out toxins

Dr Fielder said drinking at least two litres of water will hydrate the body and help maintain kidney health, which is the first step towards other wellbeing benefits.

‘Kidney function is essential for metabolism and toxin excretion – and because the kidneys are very sensitive, lower water defecates will effect the overall functionality,’ she said.

If the unwanted toxins are not flushed out, this can lead to feeling fatigued, an increase in headaches and a lack of concentration.

Improve or maintain healthy skin

Keeping hydrated will not only remove toxins from the body but will also replenish the skin from the inside out.

‘For women in particular it’s important to maintain fluid as this can rejuvenate the skin and lower the appearance of wrinkles,’ Dr Fielder said.

As the skin is the largest bodily organ it’s essential to keep it hydrated to maintain younger looking skin.  

It’s also particularly important to drink more water in summer as the body can lose excess water through sweat.
