When it comes to nutrition and nutrients in our food, they can be divided into two categories—macronutrients and micronutrients. Macronutrients and the nutrients your body needs in large amounts. Micronutrients are the nutrients your body needs in small amounts. Often overlooked, water is a vitally important component of a well-balanced diet.

Technically, water is not considered a macronutrient. But there is no other substance the we put in our bodies every day that is more important to our health than water. Afterall, we’re mostly made up of water! Nearly sixty-five percent of our body consists of water. Our blood is about 90% water. We can go several weeks without food. We can only survive a few days without water. The average person uses 2-3 liters of water every day, through sweat, urine, respiration and cellular function.

And yet, so many people go through the day improperly hydrated. Besides thirst, the signs of dehydration are lethargy, irritability, headaches, body aches, muscle cramps and fatigue. Dark colored urine may also be a sign of dehydration.

How much water do you need?
When it comes to how much water you should drink each day, there is no single formula for everyone. Research over the years have yielded varying recommendations.

The National Academies of Sciences, Engineering, and Medicine recommends about 3.7 liters for men, and 2.7 liters per day for women. Many health professionals like to keep it simple with the “8×8 Rule.” The rule states that drinking eight 8-ounce glasses of water per day is in general adequate for most adults. However, with your Outdoor Fitness exercise, your body will most likely need more.

Tip: To get more fluids in throughout the day, keep bubbly water or chilled herb teas stocked in the fridge. It will help keep you hydrated, thinking clearly, feeling energized and satiated, and prepared for your regular fitness sessions.
