As we embrace the warmth of another Canmore summer, we felt it was the perfect time to talk about something that touches every aspect of our wellbeing - hydration. Our bodies are about 60% water, making hydration a key player in everything from maintaining body temperature to energy production, lubricating joints, nourishing our skin, and improving cognitive function. We've all heard the age-old advice to drink eight glasses of water a day, but have you ever wondered why it's so important? Well, grab a glass of water, sit back, and let's dive in.
#1: Temperature Regulation: Our Body's Built-In AC
Water is our body's cooling system, quietly working behind the scenes to keep our core internal temperature steady, particularly when we’re challenging ourselves with a morning run or a mid-afternoon hike up Ha Ling. When our body heats up, water comes to the rescue, evaporating as sweat and carrying away heat in a process known as thermoregulation. Imagine you're hiking on a hot summer day. As your body temperature rises, your sweat glands get to work, releasing sweat, which is mostly water, onto the surface of your skin. As this sweat evaporates, it takes some of the heat with it, cooling you down.
This process is crucial because a stable body temperature allows our organs and bodily functions to operate at their best. Nearly every biochemical reaction that occurs in our bodies, from digestion to muscle contraction to nerve function, is temperature-dependent. These reactions are driven by enzymes, proteins that speed up chemical reactions. Enzymes work best at an optimal temperature, typically around 37 degrees Celsius (98.60 F) for humans. When we're dehydrated, with less water in our body, we produce less sweat and might overheat. This can lead to symptoms like fatigue, dizziness, and in severe cases, heat exhaustion or heatstroke.
#2: Energy Production
Ever felt like you're running on empty during a long day? Water might just be the pick-me-up you need. It plays a crucial role in metabolizing carbohydrates and proteins, our body's primary sources of fuel. Metabolism involves a series of chemical reactions that break down the food we eat into energy, which is then used for everything from moving to thinking to growing. When we're well-hydrated, these metabolic processes run smoothly. Water helps transport nutrients where they're needed, aids in digestion by forming stomach secretions, and even participates in the chemical reactions that transform carbohydrates and proteins into usable energy. Without enough water, these metabolic processes become less efficient. Nutrient transport slows down, digestion can become impaired, and the rate at which we convert food into energy decreases. The result? We start to feel sluggish, lethargic, and low on energy.
#3: Joint Lubrication: The Secret to Smooth Movement
Whether you're a seasoned yogi, an avid hiker, or someone who enjoys a leisurely walk, your joints are what keep you moving. And guess what keeps your joints happy and healthy? Keeping well-hydrated!
Water plays a crucial role in joint health, primarily through its contribution to synovial fluid. This fluid, found in the cavities of our joints, lubricates the joints, reducing friction between cartilage and other tissues during movement. It also acts as a shock absorber, helping to distribute pressure evenly across the joint and cushion it against impact.
Think of synovial fluid as the oil in a car's engine. Just as oil keeps the engine's parts moving smoothly and prevents them from grinding against each other, synovial fluid keeps our joints working seamlessly and painlessly. When we're well-hydrated, our body has enough water to produce an adequate amount of synovial fluid. This keeps our joints well-lubricated and helps to prevent discomfort or injuries. It also ensures that nutrients are delivered to the joint tissues and waste products are removed, keeping our joints healthy.
On the other hand, when we're dehydrated, synovial fluid can become less effective. This can lead to increased friction in the joints, which can cause wear and tear over time. It can also lead to a buildup of waste products in the joint tissues, which can cause inflammation and pain.
#4: Hydration and Skincare: The Fountain of Youth
When it comes to skincare, we often focus on the products we apply externally - cleansers, toners, serums, etc. But did you know that one of the most effective ways to care for our skin is from the inside out? Water helps maintain skin elasticity, replenishes skin tissues, aids in detoxification, and flushes out toxins that can lead to breakouts
Our skin contains a large amount of water, and this hydration is crucial for keeping it plump and elastic. When skin is well-hydrated, it appears smoother, more radiant, and more youthful. Water achieves this by supporting the production of collagen, a protein that gives skin its elasticity. Collagen molecules bind to water, which helps improve skin elasticity and reduces the appearance of wrinkles.
Water also helps replenish skin tissues and accelerates the rate of cell turnover. This means that it helps your body produce new skin cells, which replace the old cells that accumulate on the surface of your skin. This process is crucial for maintaining a healthy, glowing complexion. Without adequate hydration, skin can become dry, flaky, and prone to cracking.
Finally, water aids in detoxification, helping to flush toxins out of our bodies, including those that can lead to skin problems like acne and breakouts. By supporting kidney function, water helps remove waste products from the blood, keeping your skin clear and radiant.
#5: Cognitive Function Clear Water, Clear Mind
Last but certainly not least, let's talk about hydration and cognition. Our brains are approximately 75% water, so it's no surprise that hydration plays a vital role in cognitive function.
When we're dehydrated, our brains have to work harder than usual to perform the same tasks. This can lead to feelings of mental fatigue and difficulty focusing. Research has shown that even mild dehydration - as little as a 1-2% loss in body water - can impair our ability to concentrate. So, if you're finding it hard to focus on your work or other tasks, it might be time to reach for a glass of water.
Hydration also has a significant impact on our mood. This is because water is essential for the production of mood-regulating hormones like serotonin. Dehydration can therefore cause a variety of mood changes, including increased feelings of anxiety, irritability, and overall mood instability.
So, whether you're solving a complex problem at work, studying for an exam, or simply enjoying a good book, staying hydrated is one of the simplest and most effective ways to boost your brainpower and keep your mind clear and focused.
So there we have it - hydration is about so much more than just quenching your thirst. It's about supporting our body's functions, from head to toe and everything in between.

Until next time, stay hydrated, stay healthy, and keep smiling!
