Hydration 101 And Why It Matters

Hydration = life. It really is as simple as that. Your body is mostly made up of water, comprising two thirds of a man’s body and around half of a woman’s. That feeling you get of being at home when you sink into a bath or splash into the ocean? It’s because you are made of water. 

Water does too many things within your body to count. You can thank the stuff for controlling your temperature, transporting nutrients, removing waste and keeping your joints working smoothly. If you’re not adequately hydrated, your body and mind can’t perform at their highest level. 

The importance of hydration grows even further if you exercise, whether that’s a bike ride around your local park or high level competitions. There’s a lot to consider, such as the benefits of coconut water and other sports drinks, and how much fluid you should be drinking before, during and after exercise

Here, we explore the basics of hydration and why it matters, and look at why it’s so important in the context of being active. 

How Much Water Should I Drink?

As a general rule, adults need to drink 2-2.5 litres of fluid a day. If an average-sized glass is 250ml, that’s 8-10 glasses a day. The exact amount your body needs depends on factors such as your age - the older you get, the more water you tend to need, as your body is able to store less of it - the climate and how warm it is, any medical conditions you may have and how active you are. 

You have to replace all of the fluid your body loses every day, which includes 1.5 litres lost when you pee and around 500ml lost from sweat, more if it’s hot. You even lose fluid just from breathing. 

It’s a good idea to get into the habit of sipping from a glass or bottle of water every few minutes, to provide your body with frequent hydration. Carrying water with you can also be a good reminder to drink up. 

How To Stay Hydrated

It might sound easy: to stay hydrated, you drink water. But it’s not quite as simple as that. Many fluids rehydrate you, from tea and coffee, to sports drinks, soups, stews and fruit and vegetables, and what’s best to consume when you’re looking at how to rehydrate differs depending on circumstance. 

Water is, of course, the obvious choice and almost always the best choice. It’s calorie-free and free-free, if you drink tap water. If you’re not a fan of straight up water in a glass, there are plenty of ways to jazz it up. From adding fruit and herbs such as mint, lemons and berries, to drinking water with plenty of ice or carbonated water, just because it’s elemental doesn’t mean it has to be boring. And you have to drink so much of the stuff, you might as well make it interesting. 

Food provides much more water to your diet than you might think. Fruits such as strawberries and melon and vegetables such as cucumber and lettuce are almost all water, and even something like a banana is three quarters water. For around every 100ml of liquid our bodies get each day, 20ml of it comes from food. 

It's All About The Electrolytes 

Struggling to work out how to rehydrate? If you're unsure about what electrolytes are - never fear. These little minerals carry an electric charge and are great in supporting hydration, increasing our energy levels, keeping your heart beating and healthy and as a result, improving your performance.

Water naturally contains electrolytes, so consuming the recommended daily water intake will have you good to go. But if you're not a fan of water, or just want to up your intake a bit and really start feeling the benefits, try adding citrus fruits such as lemons or limes to your water for some extra flavour, or maybe consuming Spinach or Nuts - more great sources of these minerals. 

Hydration And Exercise

Hydration is even more important when it comes to exercise. If you're regularly taking part in demanding physical activities, it’s very much worth considering your hydration while you’re exercising.

The Importance of Hydration

For every pound of sweat you lose, you should be drinking around a pint of fluid to rehydrate yourself. Sports drinks, which contain electrolytes and elements crucial for bodily rehydration such as potassium, salts and sugars, are very useful if you’re working at a high intensity or it’s hot weather. 

At Innermost, we know a few things about supporting your hydration. The Fit Protein is a great option for post-workout rehydration, and comes with the benefits of coconut water thanks to it containing powdered coconut water. It contains high levels of potassium, a key electrolyte lost through sweating when exercising, to help combat tiredness and rebalance energy levels. Added magnesium helps to rebalance your electrolytes and Pink Himalayan Salt contains 85 trace minerals needed by the human body, including potassium and calcium. 

What is Dehydration?

When you’re considering how best to stay hydrated, dehydration is a key concern. Feeling thirst one clear sign, but it’s possible to be dehydrated without experiencing thirst. A better indication is to keep an eye on the colour of your urine. If you’re drinking enough fluid, your pee should be pale yellow. Any other colour, and it’s time to start sipping. 

Feeling tired and dizzy are other common signs and both indicate the importance of hydration. If you are dehydrated, drinking water is your best bet, although sports drinks can also help, especially if it’s hot and you’re sweating a lot. 

Product Inspiration 

If you're struggling to up your hydration and energy, a great way to add some pep to your step is The Energy Booster. Packed with Branched Chain Amino Acids (BCAAs) and Leucine to prioritise endurance and stamina, this product is packed with nutritional benefits. Pair this with the stylish Innermost Shaker Bottle and you've got yourself a great combo... if we do say so ourselves.

The Truth About Electrolytes
Electrolytes. You’ve seen the word plastered across sports drinks, hydration tablets, and wellness blogs. You know they have something to do with hydration and performance. But do you really need them? Or is this just another overhyped wellness trend? The Hard Truth About Hydration Most people think hydration is as simple as drinking enough water. Wrong. If you’ve ever felt exhausted despite drinking litres of water, struggled with brain fog, or suffered from muscle cramps and sluggish recovery after exercise, there’s a good chance you’re missing a key piece of the puzzle: electrolytes. Electrolytes are essential minerals like sodium, potassium, and magnesium that keep your body running smoothly. They: Regulate hydration – Helping your body absorb and retain water effectively. Boost performance – Ensuring muscles contract properly, nerves fire efficiently, and your body keeps up with demands. Reduce muscle cramps – Preventing painful spasms and fatigue caused by mineral depletion. Improve brain function – Supporting cognitive performance, reaction times, and mental clarity. Maintain pH balance – Keeping your body’s internal systems stable for overall well-being. But here’s the problem: when you don’t replenish electrolytes, your body feels it. Dehydration, fatigue, dizziness, and even impaired cognitive function can all stem from electrolyte imbalances. If you’re training hard, sweating, fasting, or simply not eating enough electrolyte-rich foods, you’re losing more minerals than you think. The Science of Electrolytes & Hydration Even mild dehydration affects brain function. Studies show that a 2% drop in hydration can impair memory, focus, and reaction time (Journal of the American College of Nutrition, 2019). Electrolytes prevent muscle cramps. Sodium, potassium, and magnesium imbalances are the biggest culprits behind muscle cramps and post-workout fatigue (Sports Medicine, 2021). Performance drops by up to 20% when you’re dehydrated. A 2020 study found that a 1-2% decrease in hydration levels can lead to a 10-20% decline in endurance and power output (European Journal of Applied Physiology, 2020). Water Alone Won’t Cut It A lot of people assume that staying hydrated is just about drinking more water. But here’s the problem—drinking too much water without electrolytes can actually make things worse. Overhydration (yes, that’s a thing) can dilute sodium levels in your blood, leading to hyponatremia. Symptoms range from headaches and dizziness to nausea, confusion, and in extreme cases, even life-threatening complications. That’s why professional athletes, marathon runners, and high performers don’t just drink plain water—they strategically replenish electrolytes to keep hydration levels balanced. How to Stay Properly Hydrated Want to make sure you’re actually hydrating your body the right way? Here’s how: Drink smarter, not just more. Hydration isn’t just about intake—it’s about absorption. Your body needs minerals to properly retain water. Eat water-rich foods. Cucumbers, watermelon, oranges, and leafy greens naturally contain electrolytes and help with hydration. Replenish electrolytes, especially after sweating. Whether you're working out, fasting, or in hot weather, your body needs sodium, potassium, and magnesium to maintain hydration and muscle function. Ditch sugary sports drinks. Many electrolyte drinks are loaded with sugar, artificial flavours, and unnecessary additives. Your body needs the right balance of minerals—not a sugar spike. Electrolytes & Everyday Life Think electrolytes are only for elite athletes? Think again. They play a vital role in daily life, too. Morning sluggishness? Your body loses electrolytes overnight. A small dose first thing in the morning boosts energy and mental clarity. Post-workout fatigue? Sweat = lost minerals. Replenishing prevents muscle cramps and aids recovery. Fasting or low-carb diets? When you reduce carbs, your body flushes more sodium and potassium—leading to fatigue and dizziness if you don’t replenish. After drinking alcohol? Alcohol is a diuretic, meaning it causes fluid and mineral loss, which is why you wake up dehydrated and groggy after a night out. Proper electrolyte replenishment before bed can help reduce hangovers. The Problem With Most Electrolyte Drinks The issue with many “electrolyte” products on the market? They don’t contain every electrolyte your bodies need or they contain electrolytes in super low concentrations so it’s more of a marketing gimmick than anything else. In addition, many are loaded with sugar and artificial ingredients including silica; an ingredient I despise and will be talking more about on our social channels. Most mainstream electrolyte drinks contain: Excess sugar – Leading to unnecessary calorie intake and blood sugar crashes. Artificial additives – Unnecessary chemicals that do more harm than good. Cheap mineral sources – Making them less effective at restoring balance. Your body deserves better. The Innermost Solution The Hydrate Blend – a science-backed, 100% natural electrolyte formula that’s free from silica, artificial ingredients, and sugar. It hydrates up to 5x more than water alone, making it perfect for everyday hydration and workouts. Unlike most sports drinks, it delivers every single electrolyte in the right balance without sugar or synthetic fillers. Whether you’re an athlete, a busy professional, or just trying to stay sharp and feel great, The Hydrate Blend helps you stay hydrated, recover faster, and perform at your best. Final Thoughts Hydration isn’t just about drinking more water—it’s about absorbing it effectively. If you’re constantly feeling tired, sluggish, or cramping up, chances are your electrolyte balance is off. So next time you feel off, don’t just chug another glass of water—make sure you’re replenishing the right minerals, too. Read more
