Water is the most essential nutrient for life. It makes up about 60% of your body weight and is involved in almost every bodily function, including digestion, circulation, temperature regulation, and waste elimination.

Despite its importance, many people don’t drink enough water. Dehydration can lead to a range of health issues, from fatigue and headaches to more serious problems like kidney stones and heatstroke.

So, how much water should you drink daily? The answer depends on various factors such as your age, weight, activity level, and environmental conditions. In this article, we’ll explore how to calculate your daily water intake and provide practical tips to stay hydrated.
