Ever have one of those days when you just can’t focus on anything? If your brain just doesn’t feel as sharp as it should, water might be the answer. That advice comes from a new research effort that looked at the results of 33 different studies.
It’s already widely known that severe dehydration(缺水) causes all kinds of terrible things to happen with the human body, including both mental and physical side effects, but what’s particularly important about this new work is that it demonstrates that even a little dehydration can cause cognition problems.
In the summer months, when the sun is baking us and the heat is sending water out of our skin, mild dehydration can occur rapidly. A dehydration level of up to two percent can happen in just half an hour if you’re exercising or doing some kind of physical work in the summer heat, and that may be enough to cause your mental faculties to suffer.
This new study showed how dehydration could affect the human brain, and the results were striking. In one test designed as a card game, volunteers who were mildly dehydrated made 12 percent more errors than the control group who had enough water. Those same volunteers performed much better after their hydration levels were brought back up to normal.
No matter what kind of a job you do, making 12 percent more mistakes will be incredibly frustrating. If you feel like your brain isn’t running well, it might be time to down a bit of water, but exactly how much you need is still a topic of debate among medical professionals, as it can vary greatly from person to person.
