How grief can affect the body

Grief is often described as a feeling, but many people notice it physically first. Sleep can become lighter or heavier. Energy can drop suddenly in the middle of the day. Appetite and digestion can change.

This is common. Loss is a major stressor, and stress affects the systems that regulate sleep, hunger, digestion and immune function. Research on bereavement shows changes in sleep, heart rate and stress hormones in the months after a loss.

Grief also does not stay with one kind of loss. People grieve people, pets, relationships, health, places, plans and versions of themselves.

There is no correct timeline and no correct way for grief to feel. Some days are heavy, some are surprisingly ordinary, and both can sit in the same week.

Small, steady care can make the physical side easier to carry: regular meals even if small, some daylight, short walks, a consistent bedtime, and time with someone you trust. If sleep, appetite or low mood stay very difficult for a long time, a doctor or grief counsellor can help.
