We have lots of expressions to describe the pain of loss—heartache, a broken heart, a punch in the gut. These aren’t just figures of speech: While grief is an emotional experience, it’s also a physical one. Studies show that <a href="https://www.sciencefriday.com/segments/the-grieving-body/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank">grief can change your physiology</a>, most dramatically in the cardiovascular and immune systems.One staggering finding? A heart attack is <a href="https://www.sciencefriday.com/segments/the-grieving-body/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank">21 times more likely</a> to happen in the 24 hours after the death of a loved one.
