Almost everyone has experienced that fluttery feeling in the stomach before a big presentation or a first date. Most of us know this feeling by the un-scientific name “butterflies".
Butterflies in the stomach is the physical sensation in humans of a "fluttery" feeling in the stomach, caused by a reduction of blood flow to the organ. This is as a result of the release of adrenaline in the fight-or-flight response, which causes increased heart rate and blood pressure, consequently sending more blood to the muscles.
One way to deal with butterflies is to convince the body that it’s not in actual physical danger. Take a deep breath and relax.
