Can dehydration affect the brain?
Your brain is strongly influenced by your hydration status. Studies show that even mild dehydration, such as the loss of 1–3% of body weight, can impair many aspects of brain function. In a study in young women, researchers found that fluid loss of 1.4% after exercise impaired both mood and concentration.
How does dehydration affect you mentally?

Does the brain swell when dehydrated?
Swelling of the brain (cerebral edema) Sometimes, when you’re getting fluids again after being dehydrated, the body tries to pull too much water back into your cells. This can cause some cells to swell and rupture. The consequences are especially grave when brain cells are affected.

How much does dehydration affect memory?

Can you recover from severe dehydration?
Recovery time for dehydration depends on the underlying cause and may also depend on how long you’ve been dehydrated. If your dehydration is severe enough that it requires hospitalization, or if it’s accompanied by heatstroke, it may take a day or two before you can be released from the hospital.
