The ideal daily water intake varies based on factors like body weight, activity level, and climate. However, staying hydrated is essential for overall health, including oral health.

Water promotes healthy skin, lubricates joints, aids kidney function, and helps flush out bodily waste. It also supports saliva production, which is vital for fighting germs and bacteria in the mouth. Dehydration can lead to a dry mouth, increasing harmful microbes and resulting in a white-coated tongue.

To prevent dehydration, drink water regularly and carry a reusable bottle to stay hydrated throughout the day. Symptoms of dehydration include dark yellow urine, fatigue, headaches, dizziness, and infrequent urination.

While individual needs vary, general guidelines suggest men should aim for 15.5 cups (3.7 liters) of fluids daily, while women should aim for 11.5 cups (2.7 liters). This includes water, beverages, and moisture-rich foods. Those in hot climates or with higher activity levels may need more.

By prioritizing hydration, you support your body's functions and overall well-being. Regularly sipping water, eating hydrating foods, and limiting diuretics like caffeine and alcohol can help you meet your hydration goals.
