If you need more proof that your emotions have an impact on your heart, the Mayo Clinic reported that broken-heart syndrome is a real thing. When you suffer heartbreak, you may have chest pains and shortness of breath that mimic symptoms of a heart attack. “In broken heart syndrome, there’s a temporary disruption of your heart’s normal pumping function in one area of the heart. The remainder of the heart functions normally or with even more forceful contractions. Broken heart syndrome may be caused by the heart’s reaction to a surge of stress hormones.”
