Dehydration(脱水) is a trouble on human performance. It can cause tiredness and weaken the attention among athletes, according to a 2018 study in the journal Frontiers in Physiology. Even mild(轻微的) dehydration can affect a person's mood or ability to concentrate.
Water is cheap and healthy. And drinking water is an effective way for most people to stayhydrated. The National Academy of Medicine suggests that adult women and men drink at least 91 and 125 ounces(盎司) of water a day. But lots of water in the morning, at noon and night may not be the best or most efficient way to meet the body's hydration requirements.
Drinking water before or during a meal or snack is a good way to hydrate. "Drinking water with amino acids(氨基酸) or fats or vitamins or minerals(矿物质), such as milk or juice helps the body take in more of the water." David Nieman says, a professor of public health at Appalachian State University and director of the Human Performance Lab at the North Carolina Research Campus. Some of his own research has found that eating a banana is better than drinking sports drinks when it comes to postexercise recovery.
For those who are hoping to stay perfect hydrated, drinking slowly and mixing water with a little food is a more effective method than quickly drinking full glasses of water between meals. "Water is good for you, but you can drown in it too," Nieman says.
