Our bodies are made up of roughly 60% water. The fluid is essential for many reasons, including the delivery of nutrients around through the blood, the replacement of fluid lost through sweating, and to help many chemical reactions that happen in our body. The human body can’t store water, and as such, it must be replaced daily. Most mature adults can lose almost 3 liters a day, so it’s important to stay hydrated. Signs of dehydration include dark urine headaches, tiredness, and lack of concentration. However, on the other end of the scale, excessive fluid can be just as harmful.

Drinking too much water can cause harm as well, hyponatremia, also known as water intoxication. It’s rare, but it can occur when large amounts of water are consumed in a short time frame. When this happens, the kidneys cannot excrete enough fluid to filter and flush out the water properly. Hyponatremia can lead to headaches and blurred visions, convulsion, swelling of the brain, and possible death. However, you’d need to consume many liters in a concise period of time for this to happen. The kidneys are the unsung heroes of the human body. Without them, we can’t survive. It’s essential to make the right decisions when it comes to the foods we eat and the lifestyles we lead to allow them to function correctly.
