If you're feeling tired and lethargic all the time, then dehydration could actually be at the route of your problems. A surprising number of people are regularly dehydrated during the day. Even a small dip in hydration levels can have an impact on how you feel. This is because our bodies are made up primarily of water and basic H20 lies at the heart of every function that our body performs; from cleansing our skin to keeping us cool; from facilitating electrical nerve impulses in the brain to allowing our muscles to move and grow. For this reason, we need a regular supply of water to ensure that we function optimally and feel good in the process. But how do you know if you're dehydrated? Well, the likelihood is that you have been experiencing symptoms that you've attributed to other causes. If you tend to get low-level tension headaches, afternoon listlessness or fatigue, stress and irritation or aching muscles, then you could be dehydrated. Equally, if you suffer from skin complaints such as dryness or blemishes, you may not be drinking enough water. So your prescription is simple. Whether you have a mains fed water cooler at work, or bottled water coolers in the office, make sure that you use them regularly to stay topped up. Aim for eight pint-sized glasses a day and don't gulp them all down in one go. Sip your water gradually throughout the day and experiment with low-sugar drinks, such as herbal and fruit teas or sugar-free cordials. Plain, filtered water also tastes delicious with ice cubes and some lime slices! Experiment and get to know which flavours you like. You may find that your taste buds start to sharpen as you drink more, making your food taste even better!
