The Importance of Hydration
Hydration is often underestimated despite being a critical nutrient. Water makes up about 70% of our body weight and is essential for various bodily functions, including cellular activity and blood composition. Dehydration can manifest through fatigue, headaches, and even mistaken hunger cues.
