Drinking Water and Dementia

Did you know that almost half of Americans drink less than four cups of water per day? Crazy, right? Turns out, dehydration is a big deal when it comes to aging and health. In fact, studies show that dehydration can speed up brain shrinkage, which is a common characteristic of aging and dementia. MRI scans have even revealed that when we're dehydrated, several parts of our brain can appear to get thinner and lose volume.

And get this - even a slight decrease in water intake, like 3 or 4 percent, can immediately impact the fluid balance in your brain. This can lead to symptoms like fatigue, headaches, brain fog, mood swings, and a decrease in energy levels.

But don't worry! The good news is that you can reverse the effects of dehydration in just a few days by simply drinking more water. The general rule of thumb is to drink eight 8-ounce glasses of water per day, which equates to about two liters.
