We all learned in school that water and hydration are important, and we may remember that we are around 65% water. If you do the math that means we’re about 35% solid, right? Well, not quite. When we are born our bodies are actually closer to 70% water. As we age and as we grow in size that percentage decreases slowly over time, dropping to around 65% as we become full grown. That percentage we’re all familiar with, however, gradually decreases as we age, accelerating significantly in the later years of our lives. In our 70s and 80s our percent water can decrease to something closer to 50-55%. So, it’s not just our bodies feeling old, wrinkled and tired as we age, it’s your cells as well.
Water is important; we all can agree to that. But just how important is it? Rather than looking at the percent of water alone, let’s dive deeper. Just how many water molecules are there in a human body? Recent estimates put it at over 1026 or 100 Septillion in a 150 pound (70 kg) adult male body. That’s 100,000,000,000,000,000,000,000,000 water molecules. To put that into perspective, there are an estimated 700 quintillion planets (1018) in the universe. That means there are more water molecules in each of our bodies than there are planets in 100 million universes. Water molecules comprise over 99% of the total number of molecules in the human body.
While that number seems inconceivably large, with every passing year, we lose overall water content as our bodies age and cells become less energized. As a consequence of this reduced energetic state, the integrity of cellular metabolism maintenance becomes less efficient, making cells leaky or stiff, rather than tight and firm. Sometimes we can slow down this natural degradation by keeping active. Biological systems are unique in that the harder we work them the better they get (within reason, of course). As we work our bodies, so the cells generate more energy and more biological water that helps offset this natural loss—stemming the natural tide aging, but not stopping it. After all we can’t go against the second law of thermodynamics, essentially stating that entropy (disorder) will tend to increase. That means that things naturally break down over time.
So, as we age and our cells become less efficient, we lose water. Around 10% or 10 Septillion molecules. That’s a big number and it represents a net loss. Meaning, we’re drinking and eating, taking in food and water every day, but we still lose water from our bodies and our cells.
Water surrounds every part of every cell in your body. Maintaining it is an important part of healthy aging. Today, we are only starting to understand how fundamentally important water is to the very essence of life.
Rewire your water, your cells, your life.
