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.

Are we forgetting how to care?

The profound act at the heart of nursing.

Recently, at a nursing leadership programme in Oxford, attendees focused on the fundamentals of care. Have we forgotten how to care? What can we re-learn from those who pioneered an ordinary yet profound act that affects millions?

Anam Cara is an old Gaelic term for ‘soul friend’, a person with whom you can share your innermost self, your mind and your heart. It is a term that Tom Hill, former chief executive at Helen House Hospice in Oxford, used to describe the relationship between his staff and the thousands of children and their families who passed through their ‘big red door’ in its first twenty-five years. The hospice (or ‘loving respice’ as it became known) had been founded by Sister Frances Dominica in 1982.

Other care in this country can also trace its religious roots. Between 1048 and 1070 in Jerusalem, the Order of St. John was founded for the purpose of helping pilgrims (“our Lords, The Sick”) who had become lost, weary, or beset by other difficulties while on their way to the Holy Land. Today, in the United Kingdom, the British Association of the Order has extended care to older people first in almshouses and later in care homes. A trustee for ten years was John Monckton, a man of ‘considerable talent, enormous integrity and deep religious conviction’; his tragic murder in 2004 led to the creation of the John Monckton Memorial Prize, which recognised and rightly celebrated commitment to care by care workers.

Today, across the world, seen and unseen, nurses, carers and families continue to provide compassionate care. “Assisting individuals, sick or well, in the performance of those activities contributing to health or its recovery (or to peaceful death) that he would perform unaided if he had the necessary strength, will or knowledge” is the very essence of nursing, captured by ‘architect of nursing’, researcher and author Virginia Henderson in 1966. Meeting more than basic needs such as breathing, eating, drinking and eliminating bodily waste (which are of essential importance), Henderson recognised the role of the nurse in enabling humans to communicate with others, worship according to their faith, satisfy curiosity and sense accomplishment.

In the desire for modernisation and professionalisation, have we lost sight of the core values and activities central to patient care?

An uncomfortable truth brought out in healthcare reports such as the Final Report of the Special Commission of Inquiry (The Garling Report) 2008, and the Report of the Mid Staffordshire NHS Foundation Trust Public Inquiry (The Francis Report) 2013 is though that this type of nursing is too often done badly or even missed, leading to pressure injury, medication errors, hospital-acquired infection, falls, unplanned readmission, critical incidents and mortality. According to nurse scientist and scholar Professor Debra Jackson, “missed care occurs much more frequently than we might think”. She cites a systematic review in which ‘care left undone’ on the last shift ranged from 75 per cent in England, to 93 per cent in Germany, with an overall estimate of 88 per cent across 12 European countries’.

In one offensively-titled paper, “Shitty nursing - the new normal?” (in which the authors apologise for the title but not the questions raised), real-life pen portraits are drawn of patients lying for hours on hospital trolleys, immobile through infection or injury, ignored by staff. Whilst acknowledging contextual factors for poor care, such as a shortage of nurses and resources, the authors argue that circumstances cannot be the sole cause of missed nursing care.

A report published by the University of Adelaide, School of Nursing, has called for nurses to ‘reclaim and redefine’ the fundamentals of care. It asks whether the cause of the problem (of missed nursing care) lies “deep in the psyche of the nursing profession itself?” “Has something happened to the way modern nursing views and values caring?” it continues. “Indeed, is nursing in danger of losing its claim to care? In the desire for modernisation and professionalisation, have we lost sight of the core values and activities central to patient care? Or is this a broader social pattern where individuals are less inclined to show kindness, compassion, and care for others even if it is a necessary requirement of the job?”

Compassion, he emphasises, is more than empathy - and way "less fluffy" but much more measurable than kindness.

Writing in the British Medical Journal, Professor of critical care medicine Peter Brindley and Consultant in intensive care Matt Morgan wonder whether doctors also “too often default to high-tech and low-touch” when patients are dying – a time “when community and connection matter most”. They powerfully begin with a mother’s comment: “Humans are gardens to tend – not machines to fix.”

Professor Sir Al Aynsley-Green, the first National Clinical Director for Children in Government and former Children’s Commissioner for England, and past president of the British Medical Association, suggests that we as a society need a “momentum for compassion”. Struck by the extremes of compassion witnessed during his wife’s treatment in the last years of her life, Sir Al wants to see a cultural transformation in healthcare: for compassion to be a key operating principle in NHS and care settings, led by the Chief Nurse’s Office; for every organisation to promote the importance of compassion at the professional level; for the views of patients and families to be sought regularly; for much earlier and better focus on compassion in undergraduate and postgraduate teaching programmes for all staff; for compassion to be inspected against by the Care Quality Commission; and for a willingness to encourage staff at all levels to expose poor practice as well as celebrating excellent care.

Compassion, he emphasises, is more than empathy - and way "less fluffy" but much more measurable than kindness. “It’s putting yourself into somebody else’s shoes – and doing something about it.” Recently appointed the UK’s first Visiting Professor in Compassionate Care at Northampton University, at the age of 80, Sir Al certainly is doing something about it. He has made it his new purpose in life to “embed compassion into every aspect of care”.

Like Sir Al, Queen Elizabeth II, the UK’s longest serving monarch, espoused compassion, in word and deed. Living a life of compassionate service, the Queen made clear that her Christian faith was her guiding principle. She speaks of Jesus Christ as ‘an inspiration,’ a ‘role model’ and ‘an anchor’. “Many will have been inspired by Jesus’ simple but powerful teaching,” she said in her Christmas Broadcast, 2000. “Love God and love thy neighbour as thyself – in other words, treat others as you would like them to treat you. His great emphasis was to give spirituality a practical purpose.”

When nurses do unto others as they would have done unto themselves, and act as role model to colleagues, not only do patient experiences of care and their outcomes improve – but so does job satisfaction for nurses: a critical factor in nurse recruitment and retention – the biggest workforce challenge faced by healthcare organisations. Across the UK, there are currently more than 40,000 nursing vacancies, and thousands of burnt-out nurses are leaving the profession early. Whether nurses decide to stay or go is driven in part by their daily experience at work. The late Kate Granger, Consultant in medicine for older people, inspired Compassionate Care Awards in her name, envisioning that such a legacy would drive up standards in care - and surely also help retain nurses, through restoring a sense of pride, achievement and fulfilment to the nursing workforce.
