How Grief Shows Up in the Body

Grief is not just something you think about. It is something you feel in your body.

When you love someone, your nervous system becomes regulated in relationship with them. Their presence affects your sense of safety, routine, and emotional balance. When they are gone, your body must recalibrate.

Mary-Frances O’Connor explains that our loved ones are encoded in our brain’s maps. When the person is gone, the brain continues to expect them to be there. That mismatch between expectation and reality creates stress in the nervous system. Let’s say no matter where you were, if you thought of them you could visualize that such as they are at home or work. But when they pass our brain can no longer visualize where they are. Check out Mary-Frances O’Connor’s book The Grieving Body to learn more.

This is why grief often shows up physically.

Common physical experiences of grief include:

• Tightness in the chest or throat

• Shortness of breath

• Digestive changes

• Sleep disruption

• Increased pain or inflammation

• Headaches or muscle tension

• A heavy or hollow feeling in the body

These symptoms are not imagined. They are the body’s response to profound attachment loss.

Supporting grief means supporting the body. Gentle movement, breathwork, rest, hydration, massage, acupuncture, and nervous system regulation can all be part of grief care. Your body is learning a new version of safety.
