What is sensehacking and can it really trick your brain into feeling happier?

There’s something oddly therapeutic of the small, mundane rituals that we’ve just built to feel something, the fridged cigarette, the hiss of a Coke can cracking open after a long day, the gentle clink of glass when you stir your iced coffee with a straw, or even the crisp sound of a page turning in an otherwise silent room. The best part about these grounding moments is that they are just sensory enough to slice through the static of your brain and make the world feel, even briefly, a little more bearable. In all honesty, all thanks to our constant state of stimulation and the pressure to keep up with the never-ending hustle culture, people are now turning to small, sensory comforts to lift their moods, often without even realising it. What does this mean? Usually, a certain texture, scent or sound ends up acting as an emotional reset button, helping the brain slow down, breathe more easily, and feel a bit more at ease.

Even though the science behind this is developing, the logic is quite simple: your brain is constantly responding to sensory input, whether you’re aware of it or not. And, especially, in a world where overstimulation has become quite the norm, even the smallest sensory shift can have a surprisingly big impact. This is exactly what sensehacking taps into: the idea that you can “hack” your senses to improve your emotional state. Not just by escaping the world (as much as we want to), but by tuning into it more intentionally, 

So what exactly is sensehacking?

As defined by Dr Anuja Luniya, a behavioural health coach, sensehacking is the art of employing sensory inputs, i.e., scent, sound, light, texture, and even flavour, to modify the way we feel, think, and react. What sets it apart even more is the direct interaction with the brain-body link through bottom-up processing. In contrast to many wellness practices, such as habit stacking or sound healing, which rely on time and discipline, sensehacking rewires your nervous system to control emotions, concentration, and stress. It works, it feels natural, and it is supported by neuroscience, making it particularly topical in a world that is under great siege from both chronic stress and decision fatigue. As scientists investigate the connection between sensory stimuli and mental health, the question arises: Can you truly manipulate your senses to achieve happiness, or is this just another so-called wellness trend that wellness gurus are promoting on Instagram?

The science behind why sensehacking works

Dr. Prarthana Shah, integrative health coach and founder of Buova, calls sensehacking “the art and science of aiming smells, sounds, sights, and tastes so they lift your mood, spark your energy, or soothe your body.” And it works fast. “One noseful of lavender, one lucky splash of sunlight, one grounding sip of warm tea—and poof, the panic wiring in your nervous system stops sizzling,” she explains.  

Scent is especially powerful because it travels directly to the emotional centre of the brain. A familiar smell can calm you or even transport you back to a memory in seconds. Sound works similarly. “Low-frequency rumbles or even soft forest chirps poke the vagus nerve, the sensors that keep stress and mood in balance,” Dr. Shah says.

Light is also a key player. Natural sunlight boosts alertness and focus, while warm evening tones signal your body to relax. These sensory shifts influence not just how you feel, but what’s actually happening inside your brain.

“When you engage your senses, you’re sending signals directly to the limbic system, the part of your brain that handles emotion and memory,” says Dr. Luniya. This helps calm the fight-or-flight response and brings the body into a more regulated state. Over time, these cues can rewire the brain through a process called neuroplasticity. “There’s even early research showing that consistent sensory-based habits can help reduce inflammation, anxiety, and sleep troubles,” she adds.

Simple ways to sensehack your day

So, how exactly can you use sensehacking in real life, without turning your day into a full-blown spa retreat? According to Dr. Shah, it’s all about weaving tiny sensory rituals into your routine, especially when you're stretched thin or teetering on the edge of burnout.

Scent: Start with your sense of smell, as it’s one of the most powerful ways to shift your mood. Keep an essential oil roller or scented balm nearby. In the morning, try peppermint to shake off grogginess. During the afternoon, a citrus scent like orange or bergamot can bring energy and clarity. And when you need to calm down post-work, before bed, or during a stressful moment, reach for lavender or sandalwood.

“Keeping a calming roller in your bag or at your desk is such an underrated trick,” says Dr. Shah. It’s an easy, on-the-go way to support your nervous system.

Sound: If you’re dragging yourself out of bed, play something lively, upbeat music, light pop, or anything rhythmic that gets you moving. During work, try instrumental playlists, forest sounds, or soft background music to help maintain focus without overwhelming your brain. When the day starts winding down, you can switch to slower sounds like ambient music, lo-fi beats, soft jazz, or calming nature sounds like rainfall or waves. These gently cue your body into rest mode.

Light: Light influences your mood more than you might think. “The first ten minutes of your day should be spent near natural light if possible,” suggests Dr. Shah. Open a window, sit on your balcony, or even just stand where the light hits. It helps regulate your internal clock and makes waking up feel easier. If you’re feeling sluggish in the afternoon, sit by a window or take a quick walk outside. In the evening, swap harsh overhead lights for warm-toned lamps or fairy lights. This tells your body it’s time to slow down and prepares you for better sleep.

Touch: Touch is grounding. It brings you back into your body and away from spiralling thoughts. After a shower, apply body oil or lotion slowly and with intention. Feel the texture, take your time. Stir your tea or coffee gently and notice the warmth in your hands. Place a warm water bottle on your lap or curl up with a soft blanket when you need comfort.
