4. Caffeine Makes You Poop 

Did you know this this beverage has another interesting property? It makes you poop! If you have already noticed this quality of caffeine, then, next time you order a cup of coffee, look around to make sure there is a WC nearby. Caffeine stimulates peristalsis. It makes your bowels contract and then relax. As a result, you make your intestinal muscles work by drinking coffee. This tip is especially useful for people who have problems with regular defecation.
