While women may have a metaphorically bigger heart, men’s hearts are bigger in a more literal sense. Women tend to have smaller internal organs, including the heart. Due to their smaller hearts and the subsequent lower volume of blood pumped per beat, women need their hearts to pump faster. Studies have found that women average 78 beats per minute while men average 70 beats per minute. These extra 8 beats per minute cause additional wear and tear on women’s hearts over the course of their lifetime, leading to higher percentages of heart problems later in life.
