Drink Up, Think Sharp - How Hydration Boosts Your Brain

Did you know that even a tiny drop in hydration can mess with your brain? Just being 1% dehydrated can slow your thinking by 5%! And if you lose 2% of your brain’s water, you might struggle with short-term memory and even basic math. Long-term dehydration can shrink your brain cells, something that happens a lot in older adults who don’t sufficiently hydrate over the years.

Ever felt groggy, unfocused, or just mentally drained? That could be dehydration, too! Some common mental side effects include:

• Brain fog
• Trouble concentrating
• Feeling down or moody
• Afternoon energy crashes
• Sleep problems

Since your brain is made up of about 85% water, it needs a steady supply to keep things running smoothly. Water powers everything from your memory to your ability to think clearly. It also helps produce the hormones and neurotransmitters your brain needs to function. And since your brain can’t store water, you have to keep refilling the tank throughout the day.

Bottom line? If you want to stay sharp, focused, and full of energy, drink up! Your brain will thank you.
