Dehydration can sneak up on you like a tired afternoon slump. Symptoms include dry mouth, headache, dizziness, and even brain fog. A 2018 study from University of Connecticut found that even mild dehydration can impair mood and concentration.
On the flip side, overhydration (hyponatremia) is rare but serious. It happens when you drink too much water too quickly, diluting your blood’s sodium levels. Marathon runners are most at risk. The fix? Balance your intake with electrolyte-rich snacks and listen to your body.
The bottom line: moderation is your best friend. You don’t need to obsess over ounces; just aim to sip consistently throughout the day.
