While the precise percentage varies depending on several factors, the average healthy adult human body is composed of approximately 60% water. The persistent myth that your body is 80 percent water oversimplifies the complex and dynamic nature of human physiology, where water content is influenced by age, sex, and body composition.

The advice to drink 8 glasses of water daily, often cited as 64 fluid ounces or about 1.9 liters, is a popular health mantra that originated from outdated guidelines. The truth is, while this is an easy benchmark, what size is 8 glasses of water isn't a one-size-fits-all metric for your hydration needs.

According to the Centers for Disease Control and Prevention (CDC), plain water has no calories and is one of the healthiest choices for staying hydrated. But does water truly have 0 calories in every form, and what is the science behind this claim?

The widely circulated recommendation to drink eight glasses of water per day is a decades-old piece of advice that has been widely misinterpreted over time. So, who recommended water per person per day, and is that guideline still a reliable measure for proper hydration? The real story traces back to past health reports that were later simplified, leading to a modern emphasis on personalized hydration needs.

While many have heard that the human body is 70% water, the scientific consensus for the average adult is actually closer to 60%. The exact figure varies considerably depending on several key factors, prompting the question, 'Is the body made up of 70 percent water?'

While the famous '8x8 rule' is easy to remember, studies confirm that a single, universal guideline for daily water intake is largely a myth. Instead of a one-size-fits-all approach, the answer to 'how much water to drink rule?' depends on a variety of personal and environmental factors.
