Benefits of Staying Hydrated

January 24, 2025

Water is often hailed as the elixir of life, and for good reason. Our bodies are made up of about 60% water, making it essential for a variety of bodily functions (Meyer et al., 2019). Yet, many of us still don’t drink enough of it. Whether you're a busy professional or a stay-at-home parent, it’s easy to overlook the importance of staying hydrated. However, drinking enough water is vital for maintaining good health and optimizing daily performance. Below are five reasons why drinking water is good for you.
 
Improves Physical Performance
One of the most significant benefits of drinking water is its positive impact on physical performance (Meyer et al., 2019). During exercise, the body loses water through sweat, and staying hydrated ensures that your muscles and joints function efficiently (Meyer et al., 2019). Dehydration can lead to fatigue, decreased endurance, and even muscle cramps, which can severely impact your workout (Meyer et al., 2019). By drinking water, you help regulate your body temperature, keep joints lubricated, and ensure your muscles have the necessary hydration to perform at their peak (Meyer et al., 2019). Whether you’re running a marathon or doing light yoga, adequate hydration can improve your performance and make your workouts feel less taxing (Meyer et al., 2019).
 
Supports Digestive Health
Drinking water plays a crucial role in maintaining a healthy digestive system (Muto, 1988). Water helps dissolve fats and soluble fibres, preventing constipation and aiding in smoother bowel movements (Muto, 1988). It also flushes out waste products from the body, promoting better kidney function (Muto, 1988). When you don’t drink enough water, your body tries to retain water in the colon, leading to constipation (Muto, 1988). Staying hydrated ensures that the digestive process runs smoothly and prevents uncomfortable gastrointestinal issues (Muto, 1988). So, if you’re feeling bloated or sluggish, it might be time to drink a glass of water.
 
Boosts Skin Health
Your skin is the largest organ in your body, and just like any other organ, it needs water to stay healthy (Williams et al., 2007). Hydration helps maintain skin elasticity, reduces the appearance of fine lines, and promotes a natural, healthy glow (Williams et al., 2007). When your body is dehydrated, your skin can become dry, flaky, and prone to wrinkles (Williams et al., 2007). Drinking water helps keep your skin cells functioning properly, ensuring that your skin remains supple and well-moisturized from the inside out (Williams et al., 2007). Additionally, proper hydration may help in the fight against acne and other skin conditions by flushing out toxins that can lead to breakouts (Williams et al., 2007).
 
Regulates Body Temperature
Water plays a vital role in regulating your body’s temperature, especially when you’re exposed to extreme heat or engaging in physical activities (Boulze, Montastruc, & Cabanac, 1983). Sweating is the body’s natural cooling mechanism, and water is a crucial component in this process (Boulze, Montastruc, & Cabanac, 1983). When you're hydrated, your body can produce sweat efficiently, which helps cool down the body and maintain a stable internal temperature (Boulze, Montastruc, & Cabanac, 1983). Dehydration can impair this cooling process, increasing the risk of overheating and heatstroke, particularly in hot weather or during intense physical exertion (Boulze, Montastruc, & Cabanac, 1983). Drinking enough water helps your body maintain a normal temperature, preventing potential heat-related health issues.
 
Enhances Brain Function and Mood
The brain is highly sensitive to dehydration, and even mild dehydration can affect cognitive function, memory, and mood (Boulze, Montastruc, & Cabanac, 1983). Studies have shown that when you're dehydrated, you may experience difficulties concentrating, feel more fatigued, or even become irritable (Boulze, Montastruc, & Cabanac, 1983). Drinking enough water can help keep your brain sharp, enhance your ability to focus, and improve your overall mood (Boulze, Montastruc, & Cabanac, 1983). In addition to its cognitive benefits, staying hydrated ensures that your brain can function at its best, promoting better decision-making, problem-solving, and productivity (Boulze, Montastruc, & Cabanac, 1983).
 
Conclusion
Drinking water is one of the simplest and most effective ways to improve your overall health. From enhancing physical performance to supporting digestive health, boosting skin appearance, regulating body temperature, and improving brain function, the benefits of staying hydrated are undeniable. So, whether you're exercising, working, or simply going about your day, make sure to drink plenty of water. Your body will thank you for it, and you’ll feel the positive effects in no time. Keep that water bottle nearby and remember that hydration is key to living your best, healthiest life!

Reduce The Risk of Developing Knee Osteoarthritis

May 23, 2025
Each year, more than 53,000 knee replacements are performed in Australia, with that number steadily increasing. It's predicted that by the year 2030, this number will rise to over 150,000. Unfortunately, genetics play a significant role in whether you will develop osteoarthritis and require a knee replacement. However, there are several proactive steps you can take to reduce your risk. Weight Management Maintaining a healthy weight is important for reducing the risk of knee osteoarthritis. Excess weight puts additional stress on your knees, increasing the risk of developing osteoarthritis. Live an Active Lifestyle Engaging in a variety of exercises, including both strength training and aerobic activities, is essential for maintaining healthy knees. Strength training helps build muscle around the knee, providing better support and reducing the strain on the joint. Aerobic exercises, such as walking, swimming, and cycling, improve cardiovascular health and promote overall physical fitness. A well-rounded exercise routine can help reduce the risk of injury and osteoarthritis. Avoid Repetitive Knee Injuries Preventing knee injuries is another key factor in reducing the risk of needing a knee replacement. It’s been shown that people who have had multiple knee injuries and or surgeries are more likely to develop knee osteoarthritis later in life.

5 Simple Steps to Stay Consistent with Exercise

April 28, 2025
1. Time of Day Identify, if you haven’t already, if you are a morning person or a night owl. Now I don’t necessary mean whether you struggle to wake up before 8am or find it impossible to fall asleep until the clocks strikes 12. I mean, identify when the BEST time is for YOU to complete 45-60 minutes of uninterrupted regular structured exercise (RSE). This can take time, but once you do find the ideal time of day for your RSE, stick to it, make plans AROUND your RSE time and make that time for yourself. Be firm but also be fair to yourself when life inevitably creeps back in to dismantle your routines. Find ways to work around it, and make it work for you. 2. Buddy System Call on a partner, friend, family member, colleague, or your furry loved ones. This person should ideally be someone who you can hold accountable, and who you know will hold you accountable. In no way do you have to train together, bonus points if you do, but they are there to encourage, support, and empower you to get to your fitness destination. 3. Goal Setting Like a lot of aspects in our lives a way to maintain consistency throughout your fitness journey is goal setting. Goal setting is a very powerful way to turn a dream or a thought into an actionable and achievable task. The simplest way to set a goal is to follow the SMART goal process. Specificity: What is it you are looking to target? Improve strength – okay, stronger in what exactly? Lose weight – absolutely, how much weight? Measurable: Can the above specific goal be measured if so, how? Achievable: Is the goal realistic or is it far-fetched. It's okay to have big goals, but it's more important to break your big goals down into smaller, more achievable goals. Relevant: Apply the goal to your life, a goal becomes reality before you know it if the goal has relevance to you. i.e. a running race coming up, would require you to train more, or maybe your wedding is on the horizon and you want to be in the best shape of your life. Time bound: The final element of any excellent goal is setting a time-based deadline. Now this doesn’t mean it’s the end, far from it, this is where you will evaluate your goal against your performance, and in turn, set another goal. 4. Have a Spot This can mean a lot of different things for a lot of different people, and can greatly depend upon your goals (yes, a call back). For many people obtaining a gym membership is the ideal way to train and maintain consistency, for others, a home-based gym with the necessities is all they need, for some a good pair of running shoes and their favourite running loop. Having a dedicated space is very important however, can be different for everyone, find what works the BEST for you. 5. Practice Like many aspects of our life, the more we do any one thing, the better we get. The same applies to behavioural changes like consistency. The first weeks can be easy because its new and exciting, or it can be daunting because its new and terrifying. However, in a roundabout sort of way, the key to consistency specifically with exercise, is finding the BEST form of exercise for YOU. Find the one where you get the most enjoyment from and run with it (pun intended). Lachlan Simpson Workers Compensation Specialist (AEP, ESSAM) Exercise Rehabilitation Services ‑ QLD
