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.

NHS: How far do we go to feed the sacred system?

Balancing safeguards and economic expediencies after the assisted dying vote.

“Die cheaply, protect the NHS” It sounds extreme, but it could become an unspoken policy. With MPs voting on 29th November to advance the assisted dying bill, Britain stands at a crossroads. Framed as a compassionate choice for the terminally ill, the bill raises profound ethical, societal, and economic concerns. In a nation where the NHS holds near-sacred status, this legislation risks leading us to a grim reality: lives sacrificed to sustain an overstretched healthcare system.

The passage of this legislation demands vigilance. To avoid human lives being sacrificed at the altar of an insatiable healthcare system, we must confront the potential dangers of assisted dying becoming an economic expedient cloaked in compassion.

The NHS has been part of British identity since its founding, offering universal care, free at the point of use. To be clear, this is a good thing—extraordinary levels of medical care are accessible to all, regardless of income. When my wife needed medical intervention while in labour, the NHS ensured we were not left with an unpayable bill.

Yet the NHS is more than a healthcare system; it has become a cultural icon. During the COVID-19 pandemic, it was elevated to near-religious status with weekly clapping, rainbow posters, and public declarations of loyalty. To criticise or call for reform often invites accusations of cruelty or inhumanity. A 2020 Ipsos MORI poll found that 74 per cent of Britons cited the NHS as a source of pride, more than any other institution.

However, the NHS’s demands continue to grow: waiting lists stretch ever longer, staff are overworked and underpaid, and funding is perpetually under strain. Like any idol, it demands sacrifices to sustain its appetite. In this context, the introduction of assisted dying legislation raises troubling questions about how far society might go to feed this sacred system.

Supporters of the Assisted Dying Bill argue that it will remain limited to exceptional cases, governed by strict safeguards. However, international evidence suggests otherwise.

In Belgium, the number of euthanasia cases rose by 267 per cent in less than a decade, with 2,656 cases in 2019 compared to 954 in 2010. Increasingly, these cases involve patients with psychiatric disorders or non-terminal illnesses. Canada has seen similar trends since legalising medical assistance in dying (MAiD) in 2016. By 2021, over 10,000 people had opted for MAiD, with eligibility expanding to include individuals with disabilities, mental health conditions, and even financial hardships.

The argument for safeguards is hardly reassuring, history shows they are often eroded over time. In Belgium and Canada, assisted dying has evolved from a last resort for the terminally ill to an option offered to the vulnerable and struggling. This raises an urgent question: how do we ensure Britain doesn’t follow this trajectory?

The NHS is under immense strain. With limited resources and growing demand, the temptation to frame assisted dying as an economic solution is real. While supporters present the legislation as compassionate, the potential for financial incentives to influence its application cannot be ignored.

Healthcare systems exist to uphold human dignity, not reduce life to an economic equation.

Consider a scenario: you are diagnosed with a complex, long-term, ultimately terminal illness. Option one involves intricate surgery, a lengthy hospital stay, and gruelling physiotherapy. The risks are high, the recovery tough, life not significantly lengthened, and the costs significant. Opting for this could be perceived as selfish—haven’t you heard how overstretched the NHS is? Don’t you care about real emergencies? Option two offers a "dignified" exit: assisted dying. It spares NHS resources and relieves your family of the burden of prolonged care. What starts as a choice may soon feel like an obligation for the vulnerable, elderly, or disabled—those who might already feel they are a financial or emotional burden.

This economic argument is unspoken but undeniable. When a system is stretched to breaking point, compassion risks becoming a convenient cloak for expedience.

The Assisted Dying Bill marks a critical moment for Britain. If passed into law, as now seems inevitable, it could redefine not only how we view healthcare but how we value life itself. To prevent this legislation from becoming a slippery slope, we must remain vigilant against the erosion of safeguards and the pressure of economic incentives.

At the same time, we must reassess our relationship with the NHS. It must no longer occupy a place of unquestioning reverence. Instead, we should view it with a balance of admiration and accountability. Reforming the NHS isn’t about dismantling it but ensuring it serves its true purpose: to protect life, not demand it.

Healthcare systems exist to uphold human dignity, not reduce life to an economic equation. If we continue to treat the NHS as sacred, the costs—moral, spiritual, and human—will become unbearable.

This moment requires courage: the courage to confront economic realities without compromising our moral foundations. As a society, we must advocate for policies that prioritise care, defend the vulnerable, and resist the reduction of life to an equation. Sacrifices will always be necessary in a healthcare system, but they must be sacrifices of commitment to care, not lives surrendered to convenience.

The path forward demands thoughtful reform and a collective reimagining of our values. If we value dignity and compassion, we must ensure that they remain more than rhetoric—they must be the principles that guide our every decision.
