Why smell jumps the queue when it comes to memories

Smells hardwire deep into the brain, writes Henna Cundill, as she explores why they jump-start such vivid memories.

When I was a 22-year-old undergraduate my mother died quite suddenly. I can't remember the name of the undertakers we used, nor the chaplain who took her funeral. I can no longer visualise what any of their faces looked like. I know I visited the chaplain’s house to plan the funeral, but I can't remember exactly where that house was. What sticks is that the day of the funeral was a sultry summer's day, and both the chaplain and the undertakers smelt of perspiration. To this day there are moments where I catch that same whiff of man-sweat in some other location, and for a fleeting second, I am a bewildered 22-year-old once more. 

Here is another memory. I attended a tiny, rural Church of England primary school in the middle of England. At the end of each school year, all of us donned our little Wellington boots, which smelt faintly of slurry (since this was dairy-farming country) and sweaty feet. Then we lined up in a crocodile and trudged through the bluebell-wood (damp leaves) and skirted the edge of fields (silage, which stings the nose) covering the mile or so between our school building and the village church. 

We would enter the church grounds through the back field, hurrying through an eerily muffled graveyard with tombstones towering far above our heads and the grass disturbingly lumpy beneath our little feet. To the chidings of “Quickly!” and “Quietly!” we children scurried down a gravel path, away from this unsettling place of death, to reach the cool sanctuary of a little church, and the comforting smells (for me, at least) of damp stone and dusty hymnbooks. 

Others may not have the same associations, but for me the smell of dust and damp stone will always cry “safety!” and the reassurance that “there are no ghosts in here!” in contrast to that troubling graveyard. From death to life. Yet, at the same time, getting stuck with my nose close to some man’s whiffy armpit on the Tube will forever insinuate that I am just a child pretending to be a grown-up, out of my depth, overwhelmed with one thousand decisions to make (“What flowers do you want for her coffin?”) and no-one to advise. In the midst of life, death again.  

On reflection I will know that my emotions are being manipulated by my nose, in ways which are more or less than helpful depending on the circumstances.

Of course, I am not 22 years old and lost anymore, no matter what that man’s armpit tries to tell me. My rational mind knows better, but my rational mind doesn’t get a say – or doesn’t get the first say anyway. This is because smell is the only one of our senses that bypasses the thalamus (the brain’s ‘filtering gate’ that decides which part of the brain needs to respond to sensory input) and goes straight to the limbic system, where emotional memory is stored.  

Sometimes it is very obvious that this is taking place, such as in the examples given above. On reflection I will know that my emotions are being manipulated by my nose, in ways which are more or less than helpful depending on the circumstances. But it can happen in more subtle ways too. Supermarkets infamously pump out smells to influence our buying choices, and we’re trying to sell our house right now, so we’ve been brewing a whole lot more coffee than we ever usually would.   

Intriguingly, scientists don’t really know why the human sense of smell jumps the queue when it comes to cognitive processing. There are biological theories, such as that the smell of predator could wake up our ancestors while they were sleeping and/or could allow them to follow a scent trail quickly when fleeing danger or seeking food. There are social theories too, such as that we don’t have a lot of good words to describe smells, so the brain just doesn’t bother trying to analyse them. Whatever the truth of the matter, the reality is that (whether we like it or not) our noses are an emotional trip-hazard.  

When I walk through those great oak doors there is a moment, a glitch in the matrix, when the unmistakable smell of church hits my nose. Dust, damp… a little hint of mouse. 

I can’t help wondering what this tells me about my religious practice. Do I go to church because I have made a cognitive decision to worship God each Sunday? Or do I go to church because I am following my nose, getting away from a world full of armpits and responsibilities to a place where I am a seven-year-old girl, all gingham dress and wellies, feeling safe. If so, does it matter?    

Truth is, my mind can give me a dozen reasons not to go to church every single week. In fact, two dozen reasons. More. It has always been a busy week; I’m always behind on work. The house always needs a sort out and the car is never washed. But because certain congregation members are normally counting on me for certain things, and because I’m still pretending to be a grown up, I typically drag myself out the door, and off to church I go.  

And week on week, without fail, when I walk through those great oak doors there is a moment, a glitch in the matrix, when the unmistakable smell of church hits my nose. Dust, damp… a little hint of mouse. My body registers this before my mind; my shoulders drop a little of their tension. Even if it’s just for a fleeting moment, I start to feel that I know for sure what is absolutely real in my life and what is just pretend.  

Is this knowledge irrational – since it doesn’t come from the cognitive part of my mind? Or is there a God who knows that the cognitive part of my mind sometimes tells me all sorts of untrue and unhelpful things. Is there a God who is choosing to reach out to me in more subtle, more ancient ways?  

I can only wonder if I have been following my nose all this time, without even noticing. Drawn along by an ancient scent trail that leads me time and time again…this way…and that way…until I reach a place where there is safety, and bread.

Separating mind and body still stigmatises mental health

Our minds and bodies are meant to be inseparable.

Rachael is an author and theology of mental health specialist.

I recently had a somewhat surreal experience whilst trying to get two consultants to agree to some treatment I needed to have.  

One was a cardiologist, the other a psychiatrist - both consultants, working in the same geographical area - and I found, to my surprise, that there was no recourse for my physical health records to be viewed by the psychiatrist and vice versa.  

And as I went through the process of trying to mediate between these two professionals, it made me reflect that whilst in theory there is agreement that our minds and our bodies are one and that they cannot be treated wholly separately, the reality is something rather different.  

Mental and physical health problems are, in fact, treated as entirely separate entities, with different trusts and funding models in place to deliver care and treatment for mental illness and physical illness.  

Now, there is probably a bureaucratic reason for this, but I believe it uncovers a perhaps unconscious belief that our minds and bodies are distant relatives at best, and not only that, but our mental health is still the poorer relation - best ignored unless it’s particularly bothersome.  

I think this separation sits at the heart of the stigma that mental health problems still face - a stigma that persists even in the mental health system. It has ancient roots. Go back to ancient Greece and its philosophers. They held to a  doctrine where the body and soul were completely separate - our bodies are simply houses for our souls. In a way, the stigma that exists about mental health is the inverse of this- that our minds are less important than our physical bodies and that caring for mental health always comes second to caring for physical health. 

Yet, also in those ancient times, the Bible's treatment of humanity shows that we are creations of mind, body, and soul—all equal, beloved, and cared for by God. In Mark’s gospel, we read that the command to love God and one another is multi-faceted: “Love the Lord your God with all your heart and with all your soul and with all your mind and with all your strength.’ The second is this: ‘Love your neighbour as yourself.’ There is no commandment greater than these.” To love one another, then, means we need to care for one another’s mental health as well as physical health and strength, as we love with our minds and bodies. 

In truth, we cannot care well for ourselves or one another without considering both our mental and physical health. To ignore the mental strain of physical illnesses like cancer, and ignore the physical pains that mental illnesses cause, such as their effects on digestion and blood pressure, is to ignore significant parts of people's suffering.  

In the Old Testament of the Bible there is the story of Elijah, one of the great prophets who flees from a murderous ruler and, whilst spiritually and physically exhausted, begs God for death. “I have had enough, LORD,” he said. “Take my life; I am no better than my ancestors.” 

These are words of desperation that echo those who struggle with their mental health, and God’s reply to Elijah’s pain is to meet him with an encounter with an angel who urges him to sleep and eat, comforting him with the words “the journey is too much for you”. There is no reprimand for Elijah’s suffering, simply comfort for a tortured mind and provision for an exhausted body. 

The answer, then, is to treat ourselves and others as the embodied creations we are, with mind and body inseparable and interconnected in ways that even science cannot quite explain or articulate.  

The answer is to trust in the embodied hope of Christ, who chose to save us through not only his bodily crucifixion and resurrection, but through experiencing the breadth and depth of human emotions so that we may never again feel alone in them. 

Both our bodies and our minds matter to God, and we need to see that reflected in society, where we care not just for single ailments, but the whole person. We need not just an awareness of our minds, but an understanding of what it means to be mentally healthy, as well as a recognition of the horrors of mental illness. Only then, I believe, can we see a society which cares and serves those most in need not simply as isolated symptoms, but as valuable creations.
