Water is an essential element of the body. Our body needs water to function. Water is the main driving force within the cells and without it, the body cannot function properly. About 75% of our body’s weight is made up of water. Dehydration occurs when our body loses a greater amount of water than the amount that has been taken. This usually happens when a person stops drinking enough fluids or loses fluids due to diarrhea, vomiting, and excessive sweating. Usually our body reabsorbs fluid in from the blood and other tissues, but when a person is severely dehydrated, the body having lack of fluid cannot supply blood to the organs and the result is fatigue, lack of energy and sometimes life threatening conditions. Any one can suffer from dehydration, but it is very dangerous for babies and older adults. So it is necessary to know how to treat dehydration at home. Here are the best ways to treat dehydration.
