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.

The earth-shaking consequences of Christmas

Imagine Tolkien being born as a hobbit in the Shire, or J.K. Rowling going to school at Hogwarts. Explore the notion of the author entering his or her own creation.

The radical uniqueness of the Christmas story can be easily lost in a culture over-familiar with carols, nativity scenes, and Christmas cards. The birth of Jesus is not, for Christians, merely the birth of the founder of their religion, comparable to Muhammad, the Buddha, Guru Nanak, or Moses. The heart of the Christian claim is that in the Incarnation, the Almighty Creator of all things has irrevocably identified himself with the human race, standing in solidarity with every person who ever existed and ever will exist.

Imagine Tolkien being born as a hobbit in the Shire, or J.K. Rowling going to school at Hogwarts. The mind-bending notion of the author entering his or her own creation is far closer to the Christian idea of Jesus than any comparison between him and other great figures of history. For Christians, he was not just a moral teacher, not just an inspiring example – not even an object of adoration and love without further qualification. He was and is all these things of course. But all those things are put in the shade by something else, totally unique and unrepeatable: Immanuel, God-among-us.

The implications of this are staggering. Dorothy Sayers puts it this way (quote slightly adapted):

For whatever reason God chose to make human beings as we are – limited and suffering and subject to sorrows and death – he had the honesty and the courage to take his own medicine. Whatever game he is playing with his creation, he has kept his own rules and played fair. He can exact nothing from us that he has not exacted from himself. He has himself gone through the whole of human experience, from the trivial irritations of family life and the cramping restrictions of hard work and lack of money to the worst horrors of pain and humiliation, defeat, despair, and death. He was born in poverty and died in disgrace and thought it well worthwhile.

The Christian God is a God who plays fair, who keeps the rules he commands us to keep, who suffered the same pain, anxiety, and daily struggle that we all suffer in the world he created.

How is this possible? Only if we hold together two things that look like a contradiction at first sight: that Jesus is both fully God and fully human, at the same time, without confusion or separation. This is how Christian dogma has been enshrined in our creeds.

The early centuries of Christianity were a delicate balancing act. Theory after theory was tried and abandoned because it failed to hold the necessary tension between ‘fully God’ and ‘fully man’. The long councils with hundreds of bishops arguing over the precise wording of the creed may seem very remote to our daily concerns, but they were trying to protect something vital to the life of the Church. One word wrong could have upset the whole balance, and Christianity would have become simply another mystical apparition or set of moral guidelines along hundreds of others in the ancient world.

If we let go of the ‘fully God’ part, then we are left with a religious teacher who may inspire devotion, offer moral guidance, or even speak with the voice of God. But we do not have the Creator himself entering his creation to experience it as we do.

If we let go of the ‘fully human’ part, then we are left with a supernatural appearance of the one who made us. He might command us to live a certain way and punish us when we fail. He might leave detailed instructions about the right way to worship him. But he did not share our condition. He did not get sunburnt, jostled in the street, woken up, pinched, teased at school, or sold a dud.

The magic is in that combination of the two, almost impossible to grasp, that puts the source of all power, truth and beauty in a collision course with the deepest fears, sufferings, joys, hopes and longings of every member of the human race. The one who made us is not unaware of what it is like to live in this world. Whatever his mysterious purposes may be for his creation, they involve humanity in a prominent position. And whatever God destines for our race is a destiny he shares. As G.K. Chesterton writes of the Incarnation:

‘Since that day it has never been quite enough to say that God is in his heaven and all is right with the world, since the rumour that God had left his heavens to set it right.’
