Why does a smell bring back someone who died?

Smell reaches the parts of the brain that hold emotion and memory faster and more directly than any other sense. That is why a scent can bring your person back before your thinking mind catches up. When you turn toward a stranger wearing her perfume, you are not falling apart. That is attachment, still doing its work.

Why does a smell hit harder than a photo?

Ask anyone what their mother smelled like and they will have to stop and think. Ask a daughter whose mother died and she can tell you the brand, the counter it is sold at, and the exact week her sweater stopped smelling like her.

There is a reason for that. Sight, sound and touch all pass through a kind of relay station in the brain before they reach the areas that handle feeling and memory. Smell takes a shorter road. The nerves in your nose connect to the olfactory bulb, and the olfactory bulb connects almost directly to the amygdala, which handles emotion, and the hippocampus, which helps store memory.

Researchers have measured what this feels like. In studies by psychologist Rachel Herz, memories brought back by a smell felt more emotional and more like being taken back in time than the same memories brought back by a photo or a word. When people in one of her brain imaging studies smelled a perfume tied to someone they loved, the amygdala lit up more than when they smelled an ordinary scent.

So a photo shows you her face. Her smell brings back what it was like to be near her.

Why do I turn around when a stranger wears her perfume?

Because your body found her first.

From the first months of life, a baby knows her mother by smell. Smell is one of the oldest ways we recognize the people we are attached to. That system does not switch off when someone dies. Grief researcher Mary-Frances O'Connor describes how the brain keeps a map that expects our person to be out there somewhere, and grief is the slow work of teaching it otherwise.

So when her scent drifts past in a grocery store, the part of you that is still listening for her answers before the rest of you can. You turn around. Your chest drops. Then you remember. You did nothing wrong in that moment. Your attachment did exactly what it was built to do.

What do I do when their clothes stop smelling like them?

Almost nobody warns you about this one. For a while, the sweater, the pillow or the scarf still holds them. Then one day it doesn't. Many people describe that day as a second loss, quieter than the first, with nobody around who knows it happened.

If you are not there yet and want to hold on to the scent a little longer, a few things help:

• Keep one piece of clothing in a sealed zip bag or an airtight container, and open it only now and then. Air, light and handling are what fade a scent.
• Keep the bottle. Her perfume, his aftershave, the soap they bought every time. You do not have to wear it or spray it. Some people find it helps to know it is there.
• Write it down. What they smelled like in the morning, in the car, after cooking. Words will keep it when the fabric can't.

And if the scent is already gone, let that be its own grief. You are allowed to miss the smell of someone.

Is it normal to smell them when they are not there?

Many grieving people describe sensing their person close by. For some, it arrives as a smell: pipe tobacco in an empty room, her lotion in the car. It is a common part of grief, across cultures, and it is usually not a sign that something is wrong with you.

If you notice smells that are not there and they do not seem tied to your grief, or they come with headaches or other changes, it is worth mentioning to your doctor.

When the smell brings back the worst day

Not every smell brings back the good years. If your person died suddenly, a smell can take you straight back to that day. Hospital soap. Smoke. The coffee from the waiting room. The cologne of the officer who knocked on the door.

That is a trauma memory, and it lives in the body the same way the loving memories do. It is also something that can be helped. EMDR therapy is built to reprocess what happened so the smell stops pulling you back into that day. If this is what you are carrying, please look for a trauma therapist. You can read more about grief after a sudden or traumatic death and about EMDR for grief.

If your person died without warning and you want something to start with on your own, I wrote No Goodbye, a journal for exactly this kind of loss.

What did they smell like?

When I asked this question on Instagram, more than six hundred of you answered, most of you in one word. A perfume. A soap. A kitchen. A workshop. Every one of those words was a whole person.
