There's a reason we were told not to blow dry our hair with the water running. Water conducts electricity. Electricity is energy. We are energy. We are electric. Now, consider this - without enough water in our bodies our electrical current cannot work properly. What happens? Fatigue, malaise, constipation - you name it.
Our blood is 83% water. The blood is the truck that transports the nutrients, oxygen and antibodies throughout our body. Without enough water, the blood is low on fuel and the necessary deliveries can't be made. Get it?
The brain is over 75% water. It controls every process that happens in our bodies. Just a 5% drop in body fluids will result in a 25%-30% drop in energy. The brain is the driver of the truck. If the 'driver' doesn't have the food it needs to drive, the truck certainly isn't going anywhere.
What should you do? Drink more water! At least half your body weight. If you weigh 140lbs, you should drink at least 70 ounces a day. More if you exercise, are outside, under stress - actually, for any reason! To give you an idea - I like to shoot for 10 glasses of water a day at 16 ounces each. That's 160 ounces and I weight 145lbs.
Learn to listen to your body. It will tell you what to give it in order to function properly. If you want to step it up, add lemon. It flavors the water and is great for the liver. I'll go into the benefits of lemon in my next article.
