For decades, advice about living longer has revolved around nutrition, exercise and sleep. Yet one of the most powerful influences on human behaviour often goes unnoticed: smell. Now, a UK-based scent expert argues that everyday aromas may quietly shape mood, reinforce positive habits and support long-term wellbeing in ways that science is only beginning to fully appreciate.

Toby Branston, spokesperson for Prowler Poppers, suggests that intentionally incorporating certain scents into daily life can strengthen routines linked to better health outcomes. Unlike sight or sound, smell connects almost instantly to the brain’s limbic system — the area governing emotion, memory and behavioural conditioning. That direct neurological link gives scent unusual power. A familiar aroma can calm the nervous system, trigger motivation or transport someone back to a reassuring memory within seconds.

Branston believes that when people deliberately pair certain smells with calming or energising rituals, the brain begins to associate those scents with specific states. Over time, those associations can help anchor healthier patterns, from improved sleep to greater focus and emotional balance.

Below are the seven aromas he recommends making part of everyday life — and why each one may matter more than people realise.

Lavender: The Foundation of Restorative Sleep

Lavender remains one of the most researched and widely recognised calming scents. Its soft floral profile has long been linked to relaxation and improved sleep quality. Sleep, in turn, plays a decisive role in long-term health, influencing everything from immune function to metabolic balance and cognitive performance.

According to Branston, placing lavender in the bedroom can create a sensory cue that signals the body to wind down. When the brain repeatedly associates lavender with rest, it can begin preparing for sleep more efficiently. This subtle conditioning may shorten the time it takes to fall asleep and improve perceived sleep depth.

In an era where sleep disruption has become commonplace, even small behavioural cues can have cumulative impact. Lavender, used consistently, may serve as a gentle psychological switch between the pace of the day and the calm required for restorative rest.

Citrus: A Natural Morning Reset

The sharp brightness of citrus — lemon, orange or grapefruit — tends to produce an almost immediate uplift in mood. Research has suggested that citrus aromas may stimulate alertness and reduce stress perception, making them particularly effective in the morning.

Branston notes that beginning the day with citrus scent exposure can help set a constructive emotional tone. The brain quickly learns to associate that sharp freshness with productivity and optimism. Over weeks and months, such reinforcement may shape how someone approaches their mornings.

Rather than relying solely on caffeine or digital stimulation, scent can act as a non-invasive behavioural cue, encouraging a more intentional start to the day.

Freshly Cut Grass: The Power of the Outdoors

Few scents feel as universally evocative as freshly cut grass. It carries strong associations with open air, green space and seasonal change. Importantly, it often encourages people to step outside — a habit consistently linked to improved mental and physical wellbeing.

Exposure to natural environments has been associated with lower stress levels, improved mood and enhanced cognitive clarity. Branston argues that even the smell itself can evoke grounding sensations, particularly when it triggers memories of time spent outdoors.

The scent becomes more than nostalgia. It becomes a behavioural nudge towards fresh air, movement and natural light — three factors closely tied to longevity.

Clean Linen: Order, Comfort and Safety

The smell of freshly washed sheets may appear mundane, yet it carries strong psychological symbolism. Clean linen signals order and care. It conveys a sense of safety and control within one’s environment.

Environmental psychology research has repeatedly demonstrated that perceived order reduces cognitive stress. A bedroom that smells fresh may subtly reassure the brain that conditions are conducive to rest.

Branston emphasises that sleep is one of the most powerful predictors of long-term health. If a scent can help make a bedroom feel more inviting and secure, it becomes a practical tool rather than a luxury. Clean linen aroma may serve as a nightly reinforcement of stability and comfort.

Fresh Coffee: Ritual and Mental Readiness

The scent of coffee brewing is, for many, the first meaningful sensory marker of the day. Even before the first sip, the aroma begins shaping expectation. It signals focus, routine and momentum.

Smell plays a role in anticipatory behaviour. When coffee aroma becomes paired with a productive ritual — reading, writing, planning — the brain begins preparing for that mental state automatically.

Branston highlights the importance of ritual in maintaining healthy patterns. Structure creates predictability. Predictability reduces stress. The smell of coffee can become a reliable cue that the day has begun in a purposeful way.

Fresh Flowers: Subtle Mood Elevation

Fresh flowers introduce both visual and olfactory stimulation into a room. Their natural fragrance softens the atmosphere and often produces a subtle lift in mood.

Studies have indicated that exposure to natural floral scents may reduce anxiety and increase feelings of wellbeing. Even a small arrangement in a kitchen or living space can shift how a room feels.

Branston describes this as atmospheric influence. A pleasant scent alters perception of space, and perception of space affects emotional state. Over time, these minor adjustments accumulate, shaping daily experience.

A Scent From Childhood: Emotional Anchoring

Of all the senses, smell is most directly tied to autobiographical memory. A single aroma can transport someone back decades, reviving not just an image but the emotional tone of that moment.

Branston advises identifying a scent associated with a positive childhood memory and reintroducing it occasionally. That sensory anchor can reconnect an individual with feelings of safety, joy or belonging.

Emotional regulation plays a crucial role in long-term health. Chronic stress has measurable physiological consequences. If a familiar aroma can briefly restore emotional equilibrium, it becomes more than sentimental — it becomes protective.

The Science of Association

The central principle underlying Branston’s advice is associative learning. When a scent consistently appears alongside a specific activity — sleeping, exercising, focusing — the brain forms a neural link between the two.

Over time, the smell alone can trigger aspects of the associated state. This phenomenon explains why certain aromas can calm or energise almost instantly. The effect may appear subtle, but small reinforcements repeated daily can influence habit formation.

Importantly, this approach requires no complex equipment or significant expense. It involves paying attention to sensory environment and using it deliberately rather than passively.

Small Cues, Long-Term Impact

Modern health advice often emphasises dramatic change. However, behavioural science suggests that sustainable improvement usually stems from modest, repeatable cues. Scent fits this framework precisely.

By incorporating lavender before sleep, citrus in the morning, floral notes during relaxation or nostalgic aromas during reflection, individuals may strengthen routines already known to support longevity.

Branston concludes that scent is rarely considered an active health tool. Yet when used intentionally, it can become a quiet but consistent ally in shaping daily behaviour.

Longevity may still depend on diet, movement and medical care. But the air people breathe — and the aromas they choose to surround themselves with — could be playing a more influential role than most realise.
