Keeping well hydrated helps the kidneys eliminate toxins. It is crucial that when we ingest fluids that we are helping our bodies detoxify, not adding toxins. As well as their role in elimination, the kidneys also maintain the fluid and electrolyte balance of the body. In Traditional Chinese Medicine the kidneys are the most important organs in terms of longevity.
Our bodies are over 70% water. Purified water is the main fluid we should be replenishing our bodies with and we don’t drink nearly enough of it. I recommend water which does not contain chemicals such as chlorine. Chlorine is a powerful oxidising agent (produces free radicals) and may contribute to heart disease. Other contaminants that are frequently found in tap water include industrial chemicals, lead and copper (from pipes) and organisms. Whenever possible, consume only purified water.
Ensuring an adequate intake of purified water is the single most important practice anyone can begin to improve their health. How much water we should drink is a contentious subject. The amount of water you need will depend on your health (heart and kidney function need to be considered), age, weight, level of activity and the temperature. A general recommendation is that 40mls of water per kg of body weight is required to maintain adequate hydration.
