Water plays a crucial role in all of the body's vital functions. It regulates temperature, removes wastes, transports oxygen and nutrients to the cells, cushions the joints and provides protection for the body's tissues. Dehydration occurs when you don't drink a sufficient amount of water. Serious health conditions may occur if these fluids are not replenished. While recommendations may vary, it is generally accepted that people should drink six to eight, eight-once glasses of water each day. Highly active people, or people who live in hot environments, may need additional fluids.
Digestive Problems
The gastrointestinal tract requires water for optimal digestion. In fact, 98 percent of the mucus layer of your stomach is composed of water. A thick mucus layer prevents acid from burning the lining of the stomach. Inadequate water consumption may result in indigestion, heartburn and constipation. Severe dehydration may result in nausea, vomiting and headaches.
Joint Problems
About 80 percent of cartilage is composed of water. Chronic dehydration may destroy the cartilage, and lead to joint problems such as arthritis. Dehydration may also cause the spinal disks, which are also composed of water, to become susceptible to herniation.
Dry Mouth and Skin
Dehydration will defy any of the benefits of even the most expensive moisturizers. Skin needs to be hydrated from the inside. Drinking plenty of water can save you money on beauty products.
Low Energy Level
Blood plasma is composed of 90 percent water. Dehydration reduces blood volume, which in turn makes the heart work harder to pump the blood and deliver an adequate supply of oxygen to the working muscles. Even the easiest workout may feel challenging.
Abdominal Bloat
Bloat is your body's way of protecting you from the extreme consequences of dehydration. When your body is not getting enough water, it stores fluid in its cells. Despite your best killer ab workout and low-fat diet, this stored fluid may accumulate in your stomach.
Poor Heat Tolerence
Water helps your body regulate its temperature. A lack of water may make warm weather exercise intolerable. Water helps your body regulate its temperature. A lack of water may make warm weather exercise intolerable. In severe cases, heat cramps, heat exhaustion or heat stroke may occur.
Tearless Crying
Crying without tears is not exactly a medical condition, but if you're playing for sympathy, tearless crying is not very effective.
