Call it “dry brain.” The moment your noodle feels even mildly parched, a bunch of its most important functions tend to go haywire. From the way you feel to the power your mind has to process info and memories, dehydration does immediate damage to your mental abilities.

In the project reported mild dehydration was defined as about a 1.5 percent loss of body weight. Here’s what his research found: Dehydrated women experienced a significant drop-off in energy and mood. Basically, they felt tired and lousy about life. “Also, women were more likely to have headaches and report difficulty concentrating.”  Along with those mood and energy deficits, your dehydrated brain also has to use a lot more energy to accomplish the same tasks.

Severe dehydration was defined as a 3 to 4 percent drop in body weight due to lack of water, this level will intensify the brain problems research uncovered.  You’re going to see substantial changes in your ability to perform cognitively.  “Learning and memory and alertness will all suffer with severe dehydration.”  Like plant leaves without water, the cells in your brain appear to dry out and contract when deprived of fluid.

How do you avoid all this? First know that if you feel thirsty, you’ve already waited too long to drink some water. “Urine color is a better indicator of hydration,” he adds, explaining that you want your pee to be a light straw color. “The darker it gets, the more you’re dehydrated.”
