- In 1998, Cornell Medical Center, NY did a survey that discovered 75% of all Americans show signs chronic dehydration.
- 37% of those people mistake thirst for hunger causing them to eat more.
- Even mild dehydration will slow your metabolism as much as 3% making you burn less calorie.
- Dehydration is the #1 trigger of daytime fatigue.
- A drop of 2% in hydration can trigger fuzzy short-term memory, trouble with basic math, and difficulty focusing.
Dehydration is very common. Many times, I hear students complain of constant headaches. When questioned, I find they drink all sweetened and/ or caffeinated drinks which only dehydrate you more.
The best time to regain your hydration level is in the morning because after a night of sleep, our body is at its lowest hydration level of the day.
Simple method for Testing your Hydration Level
You’ll need a scale that calculates a body fat percentage. Our hydration level effects the body fat percent on the scale.
Our hydration level is at it’s highest in the late afternoon and lowest in the morning.
First, measure your body fat percent in the afternoon or early evening. Then, measure it in the morning. The difference in your body fat percent between the afternoon and morning is water loss.
For example, if you weight 200 lbs with 20% body fat in the afternoon and 19% body fat in the morning, you are 1% short in water.
If you take 200lb X 0.01 (or one percent), you find that you’re 2 lbs short in water.
Since 16 fl oz equals one pound, you need to drink two 16 oz glasses of water to re-hydrate yourself in the morning.
