Water Works part 1
Civilizations worshiped it, people fought over it, and today we barely think about it. We look into water.
Growing up, I loved watching survival shows. My favorite was Survivorman with Les Stroud. Every week he went into a remote location and had to survive on his own. Overtime I noticed he always prioritized water over food. With the abundance of water all around us, it's easy to take it for granted.
Let's start with the basics: How much do we need and what happens if we don't consume water.
- Our body is made up of about 70% Water.
- Without water, we couldn't survive for a week.
- Dehydration can occur very quickly and and affects physical and mental performance.
- Men should drink at least 2.9L per day and women 2.2L, if not exposed to heat / physical exertion.
- Your water intake comes in many forms, beyond drinking it, including foods (like fruits!).
Dehydration occurs gradually from mild dehydration starting with a loss of approximately 1% of your body's fluids. The chart below shows the different stages of dehydration and how the symptoms get progressively worse.
The most surprising fact I learned was how quickly it can affect you. Even with 1-2% fluid loss, you can lose some of your mental sharpness. High performance cannot occur without maintenance. Our bodies are surprisingly resilient, able to endure tough challenges. Being able to thrive requires additional effort. Drinking water is one step toward thriving, instead of simply surviving.
