Your body is water (literally)

Humans came from the ocean. Mineral-rich fluids literally made us.

Today, our cells are made from water as well:

  • Our bones are 22% water.

  • Our muscles and brain are 75% water.

  • Our blood is 83% water.

  • Our eyes are 95% water.

Since water is virtually everywhere in our bodies, it is involved in most chemical processes needed not only to survive, but to thrive:

  • Water dissolves substances and transports them.

  • Water is needed to synthesize proteins, glycogen, and vitamins.

  • Water starts chemical reactions in our bodies.

  • Water lubricates tissues and joints.

  • Water regulates temperatures.

  • Water provides electrolytes.

  • Etc.

Since we are mostly water, not drinking enough mineral-rich water makes our bodies start to break down from the inside.

Note: Blood plasma is mostly water, since some of us don't drink enough water, our heart needs to pump more blood through our body to deliver the same cardiac output as it would if it had enough water.

Question: "How is it that our bodies can function properly if we can't perform the actions mentioned above?"

Our bodies are masters at adapting. Evolution slowly brought us here. You will find that many humans can bypass many physiological needs for a couple of years with terrible habits like

not drinking enough water, having terrible sleep quality, eating junk food, having chronic stress, etc.

Eventually, our bodies breakdown because they can't keep up, and that's when you start seeing chronic diseases, weight gain, chronic fatigue, etc.

Question: “How do I know if I'm drinking enough water?”

Well, are you experiencing any of these symptoms? Headaches, fatigue, low-blood pressure, nausea, dizziness, or rapid heart rate.

Question: “I’ve never liked water, my body is used to functioning without it”

No, is not. You are just used to being dehydrated. Unlike many other scenarios, our bodies don't adapt to dehydration, we cant train to get better at not needing water. Your body does get better at storing water once you start drinking appropriate amounts.

Question: “What’s an effective way of testing if I'm dehydrated or not?”

The quickest way of testing is looking up a urine color chart and comparing colors. Yours should be a very, very light yellow, if it is not, you are probably dehydrated. Some supplements tend to alter urine’s natural color - Do some research and see if what you are consuming plays a role in urine charts

The Institute of medicine makes these recommendations on total water daily needs:

19 y/o+ : 100oz

19 y/o+ 75oz

Keep in mind, this is the recommendation for the average Joe. Not for a Crossfitter, triathlon athlete, etc. Those numbers are a baseline. We like using the following formula to roughly estimate our water needs:
