Alcohol, Healthy Ageing, and the Future of Drinking
A new conversation about brain health, sleep, and longevity
For decades, alcohol has been woven into our social fabric — a signal to unwind, connect, and celebrate. Yet new science shows that the same substance many associate with relaxation is accelerating the very processes that undermine healthy ageing.
The Inside Story: Brain and Body
Even small amounts of alcohol affect the brain. It increases dopamine and serotonin release in the short term, but chronic use disrupts these same systems — altering mood regulation, motivation, and sleep quality.

The Inside Story: Brain and Body
Even small amounts of alcohol affect the brain. It increases dopamine and serotonin release in the short term, but chronic use disrupts these same systems — altering mood regulation, motivation, and sleep quality.
Brain-imaging studies from the University of Oxford and the University of Pennsylvania have shown that regular drinkers, even at moderate levels, exhibit reduced grey matter and accelerated brain ageing.
“The truth is there’s no safe level of alcohol consumption” says Professor David Nutt, whose work on the effects of alcohol has reshaped how we understand its impact on cognition, mental wellbeing, and physical health.
The damage isn’t limited to the brain. Alcohol dehydrates tissues, impairs nutrient absorption, and drives inflammation — all of which contribute to premature biological ageing. The visible results are familiar: duller skin, puffiness, redness, and loss of elasticity, reflecting deeper internal stress on the body’s repair systems.
Sleep, Stress, and the Ageing Loop
Poor sleep is one of the most overlooked accelerators of ageing. Alcohol may help people fall asleep faster, but it fragments deep sleep and suppresses REM, the stage responsible for memory processing and emotional repair.
Chronic disruption of sleep drives higher cortisol (the body’s stress hormone), impairs tissue regeneration, and weakens immune defences — creating a physiological loop where tiredness, stress, and ageing reinforce one another.

Alcohol and Cancer Risk
The World Health Organization classifies alcohol as a Group 1 carcinogen, the same category as tobacco and asbestos. Regular use increases the risk of several cancers — notably breast, liver, and colorectal — even at what’s often described as “moderate” drinking levels.
A Holistic Approach to Healthy Ageing
Healthy ageing isn’t about quick fixes — it’s about how everyday choices interact with our biology. Diet, movement, sleep, mental wellbeing, and social connection all have a measurable impact on how we age — not just in years, but in how we feel and function.
Research increasingly shows that small, sustainable habits have a compounding effect: regular physical activity supports brain health; a balanced diet rich in antioxidants protects the skin; quality sleep restores memory and hormone balance; and reducing alcohol intake lowers inflammation and long-term disease risk.
It’s this interplay — between what we eat, how we rest, and what we consume — that determines the trajectory of our health over time. By looking at ageing through this whole-body lens, the focus shifts from managing decline to maintaining vitality and resilience.

A New Direction: Functional Alternatives
As awareness grows, so does the appetite for change. People are not only cutting back on alcohol — they’re looking for smarter ways to unwind and connect.

That’s where innovation is taking hold. Professor Nutt and his team at GABA Labs have developed SENTIA, a new category of social drink designed to activate the brain’s GABA system — the same calming pathway alcohol targets — without ethanol or its unwanted negative health consequences.
SENTIA Spirits are formulated to support calm, mood, and sleep quality, key pillars of healthy ageing and recovery. The idea is not abstinence but evolution — keeping the social ritual of a drink, while aligning it with what science now tells us about long-term wellbeing.
