This is What Happens When You Drink Coffee on an Empty Stomach

7. Decreased Cortisol Levels

When you wake up in the morning, your body releases a hormone known as cortisol to make you feel awake. You then use coffee to feel even more awake!

Research shows that once you drink that morning coffee for extended periods, day after day, you are decreasing your cortisol levels instead of increasing them. As a result, you may feel even more tired after your coffee than before it!
