What does Water do?
Why do we as humans need water? Why can’t we just go around all of our lives and do sports or activities without needing to drink water? What does water do for our bodies, and what happens if we drink too much/too little of it?
We as humans need water because Water is essential to good health—and life. Up to 60 percent of an adult’s body weight and about 74 percent of a newborn’s body weight is water, making it the largest single substance in the human body. Water helps carry nutrients to the cells in your body, as well as carry waste products from the cells in your body. Athletes especially need water because water helps regulate body temperature by absorbing heat from your metabolism, as well as help lubricate the joints. Having water is a necessity, however there are complications if we drink too much and too little of it. Drinking too little water is dangerous because it can lead to dehydration. Dehydration can influence your mental functioning, your heart rate, and your ability to regulate body temperature and blood pressure. If you lose even 1 percent of your body weight in water, your physical performance is affected and you feel tired. If you lose 2 to 4 percent, your mental functioning is affected; a loss of more than 10 percent of your body weight is a medical emergency and if not reversed can lead to death. Sweating during exercise that is not compensated by drinking extra fluids; exercise even in cold weather can cause sweating. Hot, humid weather, High altitude, which causes rapid breathing and increased urine output, Illnesses such as poorly controlled diabetes, and illnesses that cause vomiting, diarrhea, or fever, Pregnancy, and Certain medications. Each of these conditions alone can contribute to dehydration; a combination of them can cause it more quickly. Although caffeine does cause you to urinate more frequently, the effect is short-term and does not typically cause dehydration. Both caffeinated and non-caffeinated
