PUT A PIECE OF IN THIS PART OF YOUR BODY AND YOU WILL SEE WHAT HAPPENS TO YOUR HEALTH

5. Water will optimize your brain function
   Ever felt foggy? Drink a sip of water. Studies have shown that dehydration can reduce memory, focus, and energy. Not surprising given that H2O makes up 75 percent of the brain, the authors point out. One reason for this foggy feeling? “Electrolyte balance is important for your body to function optimally. Low electrolytes can cause problems like muscle weakness, fatigue, and confusion,” says Gabriel Lyon, M.D., a functional medicine physician in New York City.
6. Water keeps your cardiovascular system healthy
   Water is a huge part of your blood. (For example, plasma, or the pale yellow liquid part of your blood, is about 90 percent water, Britannica notes.) If you’re dehydrated, your blood becomes more concentrated and its electrolyte mineral (sodium) imbalances. and potassium, according to the Merck Manual), says Susan Bloom, MD, founder of Bloom Medical Center in Rye Brook, New York. These electrolytes are needed for proper muscle and heart function.

Dr. Blum says: “Dehydration can cause a drop in blood volume and blood pressure, so you can feel dizzy and pass out when you stand up.”

Actually,a 2023 study suggests that optimal hydration may actually slow the aging process in humans, partly due to these cardiovascular benefits, although researchers noted that more studies are needed to validate the findings.
