We often hear about the importance of staying hydrated, but how much do we really understand about its impact on our health and wellbeing? Hydration is one of the most vital components of a healthy lifestyle, yet it’s something many of us overlook. With around 70% of the human body made up of water, it’s no surprise that every single cell depends on it to function properly. But what does hydration really do for us, and why is it particularly crucial for those of us engaged in regular exercise?
Why Water is Essential for the Body
Water plays a crucial role in almost every process within the body. It helps transport glucose, oxygen, and nutrients to our cells while also flushing out waste products. It keeps our joints and eyes lubricated, helps maintain healthy skin, and ensures that our digestive system runs smoothly. Quite simply, without adequate hydration, none of these processes work as efficiently.
Spotting the Signs of Dehydration
Dehydration can sneak up on you, especially if you're not paying attention to the signs. Darker urine, headaches, dry mouth, and skin are some of the more common indicators. But did you know that dehydration can also make you feel hungry? When we’re low on fluids, the brain sometimes mistakes thirst for hunger, leading to cravings for water-rich foods. If dehydration becomes severe, it can cause confusion, fainting, a fast heart rate, and even breathing problems.
The Long-Term Effects of Chronic Dehydration
It’s not just the immediate symptoms of dehydration that are a cause for concern. Long-term, chronic dehydration has been linked to an increased risk of serious conditions such as heart failure, diabetes, chronic lung disease, and even dementia. Recent research by the National Institute of Health shows that staying properly hydrated can improve longevity and lead to better long-term health outcomes.
How We Lose Water – and Why It’s More Than Just Sweat
We often associate fluid loss with sweating, but we lose water in many other ways, including through breathing and the elimination of waste. Certain conditions, such as chronic kidney disease or diabetes, can accelerate this process, as can medications like diuretics. Drinks like alcohol, sugary sodas, and even coffee can also dehydrate us, making it harder to stay on top of our hydration needs.
The Role of Electrolytes in Hydration
At Fuller Fitness, we believe that hydration and electrolyte balance are crucial, especially for those of us engaged in intense exercise. While general guidelines suggest drinking 2 to 2.5 litres of water (about 9 to 13 glasses) a day, this often needs to be increased for our more active clients. Strenuous exercise causes greater fluid loss, meaning athletes need to up their intake to meet these demands.
But it’s not just about drinking water. Fluids like herbal teas, milk, sugar-free cordials, and electrolyte drinks can also help keep you hydrated. A handy tip is to monitor your urine colour – if it’s a pale straw colour, you’re likely hydrated, but if it’s darker, you may need to drink more.
As Fuller Fitness’s clinical pharmacist Eleanor often reminds our clients, electrolytes are vital minerals like potassium, sodium, and magnesium, which help regulate fluid balance in the body. They also support muscle contractions (including those in the heart), energy production, and nerve function. When we sweat during exercise, we lose these essential electrolytes, making it important to replace them to maintain peak performance.
Eleanor recommends WHO-approved electrolyte solutions that balance these key minerals without added glucose. ORS tablets, for example, are an affordable and effective option that was developed by two clinical pharmacists. They’re widely available, but there are plenty of other good choices on the market too.
Electrolytes: More Than Just a Fitness Trend
Electrolytes have become a buzzword in the fitness industry, and for good reason. As more and more people recognise the importance of hydration in achieving fitness goals and maintaining overall health, electrolytes are being increasingly recommended as part of a comprehensive hydration strategy.
At Fuller Fitness, we take hydration seriously, not just as a way to enhance performance but as a fundamental part of living a healthier, more balanced life. So, the next time you’re reaching for your water bottle, remember – staying hydrated is about much more than just quenching your thirst. It’s about supporting your body, your health, and your future.
