why is water important for the human body

Did you know that your body weight is approximately 60 percent water? Your body uses water in all its cells, organs, and tissues to help regulate its temperature and maintain other bodily functions. Because your body loses water through breathing, sweating, and, it's important to rehydrate by drinking fluids and eating foods that contain. The amount of water you need depends on a variety of factors, including the climate you live in, how physically active you are, and whether you're experiencing an illness or have any other health problems. Water Protects Your Tissues, Spinal Cord, and Joints
Water does more than just quench your thirst and regulate your body's temperature; it also keeps the tissues in your body moist. You know how it feels when your eyes, nose, or mouth gets dry? Keeping your body hydrated helps it retain optimum levels of moisture in these sensitive areas, as well as in the blood, bones, and the brain. In addition, water helps protect the spinal cord, and it acts as a lubricant and cushion for your joints. Water Helps Your Body Remove Waste Adequate water intake enables your body to excrete waste through perspiration, urination, and defecation. The kidneys and liver use it to help flush out waste, as do your intestines. Water can also keep you from getting constipated by softening your stools and helping move the food you've eaten through your intestinal tract.

However, it should be noted that there is no evidence to prove that increasing your fluid intake will cure. Water Aids in Digestion Digestion starts with saliva, the basis of which is water. Digestion relies on enzymes that are found in saliva to help break down food and liquid and to dissolve minerals and other nutrients. Proper digestion makes minerals and nutrients more accessible to the body. Water is also necessary to help you digest soluble fiber. With the help of water, this fiber dissolves easily and benefits your bowel health by making well-formed, soft stools that are easy to pass. Water Prevents You From Becoming Dehydrated Your body loses fluids when you engage in vigorous exercise, sweat in high heat, or come down with a fever or contract an illness that causes vomiting or diarrhea. If you're losing fluids for any of these reasons, it's important to increase your fluid intake so that you can restore your body's natural hydration levels. Your doctor may also recommend that you drink more fluids to help treat other health conditions, like bladder infections and urinary tract stones. If you're pregnant or nursing, you may want to consult with your physician about your fluid intake because your body will be using more fluids than usual, especially if you're. How Much Water Do You Need? There's no hard and fast rule, and many individuals meet their daily hydration needs by simply drinking water when they're thirsty, according to a report on nutrient recommendations from the Institute of Medicine of the National Academies.

In fact, most people who are in good physical health get enough fluids by drinking water and other beverages when they're thirsty, and also by drinking a beverage with each of their meals, according to the Centers for Disease Control and Prevention. If you're not sure about your hydration level, look at your urine. If it's clear, you're in good shape. If it's dark, you're probably dehydrated. But why exactly is water important to human biology? There are five main functions of water in the human body: Cell life is based on the fact that cells have water inside them. Water is used to transport nutrients to cells and within cells (intracellular). If cells don't get nutrients including vitamins, minerals, and sugars, they die. As mentioned, water is needed for transport. It's how oxygen and food make it through our bodies, and how blood flows through the veins and arteries to take those nutrients to where they're needed. Blood is, after all, 92% water. In fact, 60% of your entire body is water! Chemical reactions also require water. Chemically, water is an important solvent and a major part of a lot of chemical reactions that happen inside the cells of our bodies. You can think of the human body as a gigantic chemistry lab: chemical reactions are how our food is turned into energy, how our waste is handled, how blood is oxygenated, and thousands of other processes.

Water is also useful to control your body temperature. That's because water has a high heat capacity, meaning it takes a lot of energy to change its temperature. This makes releasing warm water the perfect way to cool off - that's why you sweat. When the water evaporates, it takes its stored heat with it. It also makes it harder for the environment to cause your core body temperature to change. Last of all, water is important for the excretion of waste. Those chemical reactions that happen in the body often produce waste products and toxins that need to be removed. We remove them through urine, which is mostly water. If your urine had the consistency of honey, It's fair to say you'd spend a lot more time in the bathroom! Water is a compound made of molecules containing two hydrogen atoms and one oxygen atom. That might not sound very impressive, but water is necessary for life on Earth. Without water, we wouldn't have evolved. In fact, humans cannot go more than a few days without it. Cell life : water carries nutrients to, from, and within cells Transport : the blood is mostly water, around 92% Chemical reactions Temperature regulation Waste excretion Because of this, water is the most important natural resource in the world.
