5. Bad Breath

Saliva removes germs and food particles from the mouth, which is important for preserving dental health. When you’re dehydrated, saliva production decreases, allowing bacteria to thrive in the mouth. This can lead to bad breath, also known as halitosis. Drinking water regularly helps keep the mouth moist and reduces the risk of oral odor.

6. Reduced Cognitive Function

Dehydration can impair cognitive function and affect your ability to concentrate, reason, and solve problems. Even mild dehydration can lead to fatigue, brain fog, and difficulty focusing. Staying hydrated is essential for optimal brain health and cognitive performance.
