Water is essential for human survival because it performs many important functions in the body. It helps to regulate body temperature, transport nutrients and oxygen to cells, and remove waste and toxins from the body. Additionally, water is necessary for proper digestion and can help to prevent dehydration, which can cause fatigue, dizziness, and other health issues.
It is important to drink enough water every day to maintain good health and support the body’s functions. The amount of water that an individual needs to drink can vary depending on factors such as age, weight, and activity level, but a general guideline is to aim for 8 cups (64 ounces) of water per day.
