how does drinking water help your brain
A Lack Of Water Is A Lack Of Brain Power. Led by Dr. Caroline Edmonds, researchers in the UK recently conducted a study showing that even mild dehydration has a negative effect on the brain's performance. Drinking water, the researchers found, can improve the brain's ability to complete tasks that require a rapid response.
Dehydration (Severe) â Due to the fact that the brain is 75% water, it is important to make sure that it stays hydrated. Although failing to drink 8 glasses of water a day isnât going to do any sort of damage, if you go without any fluids for a 24 hour period, you will likely end up killing some brain cells.
