It is all about chemistry.

Caffeine is a nitrogenous organic compound of the alkaloid group that acts as a central nervous system stimulant. It is found in the seeds, fruits, nuts, or leaves of a number of plants native to Africa, East Asia, and South America. Caffeine has a three-dimensional structure similar to that of adenosine, which allows it to bind and block its receptors. Caffeine is capable of binding to adenosine receptors on the surface of cells without activating them, thereby acting as a competitive antagonist.

Caffeine is known for its nootropic properties, which include increased alertness, attention, and task switching. A systematic review and meta-analysis from 2014 found that concurrent caffeine and L-theanine use has synergistic psychoactive effects that promote alertness, attention, and task switching; these effects are most pronounced during the first-hour post-dose

In addition to the previous research, it is also well-known about their heart benefits. If looking to ask someone out on a date or to get to know someone special, why not suggest grabbing a cup of coffee? Not only will you get to enjoy the many benefits of caffeine, but you’ll also have the opportunity to connect with someone over a shared love of this delicious beverage. Who knows? You might just find your perfect match over a steaming cup of coffee. Cheers!
