Understand what we thirst for

Whether for water or meaning, it’s a primal force.

Quenching thirst is a global problem. It can also be profoundly personal, impaired by illness. For nurses, it can be ethically and emotionally difficult, when treating dying patients. But is there ultimate relief? 

Thirst is the subjective sensation of a desire to drink something that cannot be ignored. The world is thirsty; globally, 703 million people lack access to clean water. That’s 1 in 10 people on the planet. 

Thirst is a life-saving warning system that tells your body to seek satisfaction through swallowing fluid. It works in partnership with other body processes - such as changes in blood pressure, heart rate and kidney function - to restore fluid, and salt, levels back to where they belong. Failure of any part of this beautifully balanced system leads to dehydration (or water intoxication), and perhaps to seizures, swelling of the brain, kidney failure, shock, coma and even death. 

Sometimes it’s difficult to quench thirst, because of problems with supply. According to the World Health Organization, at least 1.7 billion people used a drinking water source contaminated with faeces in 2022. Sometimes in war, water is weaponised, with systematic destruction of water sources and pipes. Water laced with rat fur, arsenic and copper has meanwhile been reported in prisons across the USA.  

At other times, there may be “water everywhere, but not a drop to drink” because of individual problems with swallowing. As a nurse, some of my most heartbreaking moments have been when I have been unable to fulfil a need as basic as a patient’s thirst; when even thickened fluids have led to intense coughing and distress, and a realisation that I can only moisten mouths and give so-called “taste for pleasure”: very small amounts of a favourite liquid or taste using a soft toothbrush, or a circular brush gently sweeping around the mouth and lips to release some of the liquid - even, and especially, at the end of life when the patient is unconscious. 

Difficulties in drinking are common in dementia when fluid can seem foreign and swallowing a surprise to the system. It’s thought that over 50 per cent of people in care homes have an impaired ability to eat or drink safely; 30 to 60 per cent  of people who have had a stroke and 50 per cent of those living with Parkinson’s may struggle to swallow. 

Other conditions that may affect swallowing include multiple sclerosis, cerebral palsy, and head and neck cancers. Diabetes is characterised by a raging thirst owing to problems with insulin (diabetes mellitus) or an imbalance in antidiuretic hormone levels (diabetes insipidus). In intensive care, patients are predisposed to thirst through mechanical ventilation, receiving nothing by mouth, and as a side effect of some medications. But thirst is a “neglected area” in healthcare, writes palliative care researcher Dr Maria Friedrichsen.  

“Knowledge of thirst and thirst relief are not expressed, seldom discussed, there are no policy documents nor is thirst documented in the patient’s record. There is a need for nurses to take the lead in changing nursing practice regarding thirst.” 

Is there another thirst that is also being missed in nursing, and in life in general – a spiritual thirst, beyond the physical desire to drink? In his book, Living in Wonder, writer Rod Dreher argues that humans are made to be spiritual, and that a critical sixth sense has been lost in a “society so hooked on science and reason”. We humans crave love in our deepest selves; we have an insatiable thirst for everything which lies within – and beyond – ourselves. Auschwitz survivor Viktor Frankl, who was later appointed professor of psychiatry at the University of Vienna, became convinced that human beings have a basic “will for meaning.” “The striving to find a meaning in one’s life,” he wrote, “is the primary motivational force in man.”  

In the harsh sun of a Middle East day, an ancient story of a man and a woman encountering each other at a water well illustrates this dual thirst for water and meaning. The man, Jesus, thankful for a drink of water given to him at the well by an outcast Samaritan woman, said that “Everyone who drinks this water will be thirsty again, but whoever drinks the water I give them will never thirst. Indeed, the water I give them will become in them a spring of water welling up to eternal life.” In that midday sun, such imagery made a powerful statement.  

Being mindful of spiritual thirst when drinking water is something also captured in a Ghanaian proverb and pictured perfectly in the many birds that drink by gravity, so tipping their heads back when they swallow.  

“Even the chicken, when it drinks, 

Lifts its head to heaven to thank God for the water”. 

Unsatisfied thirst is part of the human condition, we long for something more; it’s living proof of our immortality, says French poet Charles Baudelaire. Despite his Olympic success, athlete Adam Peaty said that society didn’t have the answers he was seeking, and that a gold medal was the coldest thing to wear. He “discovered something that was missing” when attending church for the first time, and now has a cross with the words “Into the Light” tattooed across his abdomen, symbolizing his spiritual awakening. We are more than mechanical machines with physical needs. We are rather gardens to tend in a dry and thirsty land, with souls in need of intensive care.

Riding from darkness to light

Long-distance cycle rides give Graeme Holdsworth time to contemplate traveling from light to darkness and back again. And, to grapple with the wordless way our bodies do what they were created to do.

Graeme Holdsworth

Graeme is a vicar of Marsden and Slaithwaite in West Yorkshire. He also cycles and juggles.

I’m standing next to my bicycle at a petrol station in Blackpool, it is 1am. I’m eating a cheap cheese sandwich and drinking cold coffee from a can. What I want is hot coffee, but the machine only takes cash, and the cash machine charges for withdrawals. I’m making do with cheap and cold, because the need for calories outweighs the need for taste. On this night, I’m cycling from Slaithwaite to Blackpool and back, checking the route for a cycling event I’m organising. It’s an audax: a type of sporting experience typically documented by forecourt-chic social media posts. Its name is derived from the French for audacious. 

A glance though long-distance cycling blogs, vlogs and curated media, hints at an experience of transcendence; the emptying of self, in the search of meaning from the zip of tyres over tarmac as the kilometres click past.  

The reality, however, can be more mundane: long distance cycling often involves sitting on a weed strewn curb, while a friend fixes a puncture and though the clouds are not quite heavy enough to rain, there’s a mizziness to the air that seeps through your sportwool baselayer. There is no film crew to capture this epic moment, and you’re alone with your thoughts, which are mainly thankfulness that it isn’t your puncture. 

I’m a vicar in West Yorkshire, but haven’t always been a vicar, or even a Christian and I’ve been riding bikes for much longer than I’ve been a person of faith. As a child cycling was about belonging, I was part of a BMX community whose hierarchy was measured by how high you could bunny-hop. Later, that belonging was replaced with a different sort of identity, found through music. It was only when I was older and fatter that I rediscovered cycling thanks to my wife, who thought we both needed some exercise. 

We loved to explore, and perhaps this physical exploration was why we also began a journey of spiritual exploration. 

Together we remembered how to cycle, and as we gathered experiences, we grew in the wisdom of the cyclo-tourist. We learned that mudguards and rain capes are things of comfort and therefore beauty. We loved to explore, and perhaps this physical exploration was why we also began a journey of spiritual exploration. I’ve no intention to suggest that cycling is a gateway drug to Christianity, more that perhaps our curiosity was being fed physically, mentally, and spiritually, in ways that were not of our making. 

The first time I noticed a spiritual element to my cycling was coming back from a meeting, crossing the North Yorkshire Moors at night. It was autumn and the evening turned to dark quite early, leaving only a puddle of weak bike light to ride with. A phrase from morning prayer returned to me: ‘even the darkness is not dark to you’. A single line from a psalm in the Bible. This one line, on this one night, redefined my relationship with God. Even though all around me had turned to darkness, there was nowhere I could be lost from God. 

These remote fans and supporters are constructing narratives to explain rider’s movement, or lack of it. Yet the rules of self-sufficiency mean you are alone, no one can set you back on the right path. 

Not being lost is an important element to cycling a long distance, especially in a race. In events like the TransContinental – a multi-day self-sufficient cycle race across Europe, spending hours cycling in the wrong direction could be a racing disaster. Race winner Emily Chappell, in Where there’s a Will, eloquently documents the racer’s experience of being ‘watched over’. She tells of ‘dot-watchers’ following a rider’s GPS tracks across a map of Europe. These are remote fans and supporters constructing narratives to explain rider’s movement, or lack of it. Yet the rules of self-sufficiency mean you are alone, no one can set you back on the right path.  

Being alone with your thoughts is a common theme to long distance cycling. While our bodies silently convert glucose into energy through glycolysis, and our muscle memory converts this into kilometres covered, our minds are set free to process our past and present experiences.  

During my time at theological college, I wanted to explore the idea of physical exercise being an expression of prayer. I tried to grapple with the wordless way our bodies do what bodies were created to do. Can our bodies worship without words? Is there a physical language of lactic acid, originally written by a creator who celebrates when creation is true to itself? There’s a poetic language in the Bible that hints at this, that  

‘the mountains and hills will burst into song before you, and all the trees of the field will clap their hands’.  

Pro-cyclist Jens Voigt famously told his legs to shut up… maybe he should have let them sing. 

Audaxing, long distance cycling, racing across continents; these are extraordinary journeys in which we might travel from light to darkness and back again. Simultaneously, there is a physical descent from adventurous confidence to uncertain determination, where the will to go on is no longer found in the legs, but in a dogmatic determination to see this through. Then, with the dawning of the day, there is a fresh hope: a hope of warmth and a return to strength. With the dawning of the day, the opening of the first coffee shop and this long-distance cyclist’s prayer is answered. 

“O Lord, open my lips, 

and I shall drink this coffee.”
