Drinking enough water is important. Especially when it's very hot like today. In addition, another positive effect has been discovered:a glass of water has a positive influence on your reaction speed.
After drinking a glass of water, people respond up to 14 percent faster to a cognitive task, for example when they have to touch the largest circle on the computer as quickly as possible. Not surprisingly, the effect is greatest in people who are very thirsty.
The test subjects were given a muesli bar after a night without drinking. The other half also got a glass of water. The group that had been given water appeared to respond more quickly to the tests. According to the researchers, it is quite possible that mild dehydration already has a direct influence on the performance of the brain. Thirst probably distracts from the task at hand. Almost 80 percent of our brain is made up of water, so it's important that you get enough of it.'
