How Many Glasses Of Water You REALLY Need Per Day

They say the secret to keeping skin hydrated, healthy and radiant is drinking eight glasses of water a day.

It's a common piece of advice we have all heard from medical experts... but how many glasses of water should we really be drinking?  

According to one New York-based lifestyle editor, working out your ideal daily water intake is as easy as can be - and will leave you feeling in great health, and with a glowing complexion to boot. 

Kelsey Clark, lifestyle news editor at My Domaine, revealed that her doctor told her to use a rule which 'allows you to personally tailor your daily water consumption based on your weight'. 

'Here's her trick: Take your weight and divide it by two to identify the number of ounces of water you should drink per day, then you can convert it into grams if that's easier,' she explained.   

From there, she was able to work out her daily intake, which was roughly four glasses of water each day.

However, Sydney dietitian Lee Holmes revealed to Daily Mail Australia there are actually several other factors to look at before determining exactly how much water you should be drinking - while sharing the one H2O myth you need to stop believing.

'I understand the reason [behind the water to weight ratio], but I think it makes it too complicated,' Ms Holmes told Daily Mail Australia.

'Similar to diet, I believe that water intake should be individualised, and this should be considered when giving guidelines.

'I do think tailoring it to your weight makes sense however, other factors such as how much you exercise or move will impact the amount of water you need per day. 

'Plus if you suffer from gut issues such as constipation drinking more water can help.

'Once you're able to listen to your body, you'll be able to better understand your thirst cues and act accordingly. 

'Giving a strict approach can take away our natural intuition and may make people feel that they have to guzzle down a litre at a time rather than spreading their intake throughout the day. 

'However, some people work best with rules and guidelines and that's okay too.' 

She said the common myth people assume when it comes to drinking water is: 'You can't overhydrate.'

'The truth is, having too much of a good thing is never a good thing,' she said. 

'While it's unlikely that the average person will drink too much water, it is possible and can cause an imbalance of electrolytes.

'Rather than knocking back litre after litre, keep a water bottle next to you and sip mindfully throughout the day.'

The holistic nutritionist still believes the standard recommendation is: eight glasses a day, not including alcohol. 

'The Australian Dietary Guidelines recommends 30ml of water per kg of body weight per day,' she said.

'I like to drink a warm water in the morning and one at night and then just cold water through the day.'

For glowing, radiant skin, Ms Holmes said as well as drinking water, there are foods you can eat for a healthy complexion.

'Drinking water is key to keeping the skin hydrated and radiant as it keeps the skin moist, even helping to reduce fine lines and wrinkles,' she said.
