 Butterflies In Your Stomach It’s five minutes before your big job interview. As you wait in the outer office, your palms start sweating, your feet shuffle¹ back and forth², and the butterflies in your stomach are fluttering double time. Butterflies in your stomach? In the late 1940’s, a pair of medical researchers came across an unusual patient a soldier with a permanent opening between his inner stomach and his skin. The researchers used this opening as a window on the patient’s stomach physiology³. If the patient was put in a stressful situation, the researchers discovered a sudden decrease in the amount of acid that the stomach produced. They also discovered a decrease in the blood flow to the stomach. The butterfly sensation is part of what happens when your body goes into “fight or flight” mode. If you’re confronted with a highly threatening situation an important job interview, perhaps adrenaline floods into your bloodstream. This adrenaline raises your overall metabolism⁴ while it increases your heart rate and blood pressure. It also increases the sensitivity and strength of the smooth muscles in your stomach. This added sensitivity is what causes the fluttering sensation. Butterflies are just one way that your stomach can react to extra adrenaline. If the adrenaline level continues to rise, the electrical activity in your stomach muscles increases and your stomach will begin contracting more frequently than usual. You will stop feeling butterflies, and your stomach will start feeling “tied in knots” instead. The best way to deal with these problems is to convince your body that it’s not in actual physical danger. Take a deep breath and relax. Job interviews aren’t that dangerous, are they?
