The team at Twinings Foodservice recently spoke to Colette Heneghan, about the importance of drinking water.

Feeling tired? Drink water. Losing concentration? Drink water. We’re told over and over again to drink more water, but does it really make a difference? Colette Heneghan, Peak Performance & Nutrition Coach and Author MSc, BSc and an expert in hydration says it absolutely does.

“Even just a couple of hours in an air-conditioned room is going to have a negative effect on hydration. Normal daily turnover of water is 4% of body weight, just from everyday activities such as breathing and normal organ function. Negative effects can be observed from just 1%, so in a matter of a few hours of normal working, if you haven’t had water then there could already be implications for your performance.”

The Natural Hydration Council cite that 89% of us are not drinking enough water every day[1], yet being just 1% dehydrated[2] already starts to affect our cognitive performance and short-term memory. Bouts of tiredness, headaches and lack of concentration may also be experienced, yet simply maintaining our water intake can rehydrate us and help to reverse these symptoms of dehydration. The team at Twinings Foodservice also asked Colette specifically about the importance of water for students:

A Fundamental…

“Drinking water should be a fundamental for students,” explains Colette, “it’s something that has to be spoken about. We need to get more focus on hydration as we’re missing a really easy fix here for many of our day to day symptoms such as tiredness, headaches and brain fog.”

“For students sitting in a lecture for a couple of hours, without water, concentration and cognitive function can be impaired. If you have been in a lecture for just 2 hours without a drink, it’s likely you’re dehydrated and by the end of it, you’ve already been less brilliant than you wanted to be. Interestingly, the results of a study[4] on adult students drinking water during their exams – those students who took water into an exam performed better than those who didn’t. Students received significantly better grades than those who didn’t drink water throughout the exam.”

“Worryingly, air-conditioned buildings have an even greater effect on dehydration levels. In theory, we should be sipping water every hour to maintain hydration for optimum performance. At the end of the day we want to be at our best, so why comprise that state!?”

But the benefits of hydration are not just confined to tiredness and memory as Colette explains, “Another factor with dehydration is that it can affect our immunity, potentially making students more susceptible to colds and infections.”

But not all drinks are the same…

“There is a difference in the type of hydration that we receive from different drinks”, explains Colette, “All drinks have some hydration, but the gold standard is water. The ideal drink is something that doesn’t have sugar and doesn’t have anything artificial. The problem however, is that one of the biggest barriers to drinking water is that we don’t like the taste.”

The way forward…

So, how can we increase our water intake?  “If we simply drank water immediately after we woke in the morning, after hours of dehydration, it would be a massive upgrade to our day.” Explains Colette, “Water bottles are also an easy win, they are portable and are on hand for sips of water to be taken throughout lectures.”

Jacqui Chapman, Shopper Marketing Manager at Twinings Foodservice recaps,

“We all know that we should drink more water, yet still almost 9 in 10 of us simply don’t drink enough to keep our hydration levels at the optimum level for brain and body performance. We should be drinking around 6 to 8 glasses a day but one of the biggest barriers to drinking water is the taste[3]. This is exactly the reason that Twinings developed Cold In’fuse. Cold In’fuse is the first infuser that is able to work with cold water and is sugar free and all natural. For those who find plain water boring and hard to drink, adding a Cold In’fuse bag to cold water will release a delicious fruity flavour which makes it easier to hit the recommended 6/8 glasses or 2 litres per day.”

Colette highlights the brilliance of Cold In’fuse to help us to drink more water,

“Because of the way the bags work it’s really just like having water, as they have minimal intervention to the water in terms of hydration. University caterers can sell the bags within the staff restaurant just as they would a cup of tea, coffee or bottle of cold drink. Because the bag turns the water into an appealing colour and provides a fruity taste, it will encourage students to take extra gulps of water more regularly.”

As Colette summarises, it’s all about ‘being brilliant’ and in developing Cold In’fuse, Twinings hopes to make every one’s day that bit more brilliant!”
