Subjective sensory sensitivity in healthcare settings: a qualitative investigation of aversive experiences and barriers to access care
This qualitative study of 77 participants reveals that sensory sensitivity significantly hinders access to and participation in healthcare by causing distress and triggering aversive reactions to environmental stimuli, while highlighting a critical need for increased staff awareness and sensory-inclusive accommodations to improve care experiences.

Imagine walking into a room where the lights hum with a harsh, flickering intensity, the air carries the sharp, chemical sting of disinfectant, and a dozen conversations, coughs, and ringing phones overlap into a chaotic wall of sound. For most people, this is merely an uncomfortable background noise, something to be tolerated while waiting for an appointment. But for a significant portion of the population, this environment is not just annoying; it is physically and emotionally overwhelming. This condition, known as sensory sensitivity, means that the brain processes everyday sights, sounds, and smells with an intensity that can trigger distress, panic, or a need to flee. While this sensitivity is often discussed in the context of specific diagnoses like autism or migraine, it also exists as a standalone experience for many people in the general population. The question that remains largely unanswered is how these intense reactions play out in the very places designed to heal: hospitals, clinics, and doctor's offices. If the environment meant to cure a patient is the very thing causing them pain, does that prevent them from seeking help at all?
A team of researchers at Cardiff University set out to explore this exact problem by listening directly to the people living with it. They did not rely on medical records or clinical observations, but instead invited sixty-nine adults and eight caregivers to share their personal stories. To find the right people, the researchers first asked hundreds of volunteers to complete a screening questionnaire about their reactions to sensory input. Those who reported the highest levels of sensitivity were then asked to describe their recent experiences in healthcare settings. The goal was to understand not just what triggers these reactions, but how those reactions change the way people interact with doctors, nurses, and the healthcare system itself.
The stories that emerged were strikingly consistent. Participants described healthcare environments as places of sensory assault. The most common triggers were bright, white fluorescent lights that seemed to vibrate or flicker, the overwhelming smell of cleaning products and disinfectant, and the cacophony of other people talking, coughing, or crying. For many, it was not just one sense being overwhelmed, but a combination of them all at once. A participant might be waiting in a crowded room where the lights are too bright, the air is too warm, and the noise of a ringing phone mixes with the sound of a child crying. In these moments, the physical reaction is immediate and severe. People reported their heart rates spiking, their breathing becoming shallow, and their heads pounding with pain. The mental toll was just as heavy; the effort required to simply sit still and listen to a doctor became so exhausting that many found they could no longer concentrate on the conversation or remember what was being said.
These sensory challenges did more than just make a visit unpleasant; they actively blocked people from getting the care they needed. The researchers found that for many participants, the dread of a sensory overload was enough to make them delay appointments or avoid them entirely. Some described physically leaving a waiting room or a consultation because the environment had become unbearable. Others reported that even when they did manage to stay, the quality of their care suffered. Because they were using so much mental energy just to cope with the noise and the lights, they struggled to explain their symptoms clearly or to understand the advice given to them. In some cases, this led to inadequate pain management or missed diagnoses, as the patient was too overwhelmed to speak up or too distracted to process the information.
The study also highlighted a painful cycle of silence. Many participants admitted that they did not tell their doctors about their sensory struggles. They feared being judged as difficult or fussy, or they believed that the staff were too busy to make any changes. Even when they did speak up, the response was often dismissive. Some participants recounted being told their sensitivity was just anxiety, or being ignored when they asked for a dimmer light or a quieter room. This lack of understanding created a sense of isolation, where the person seeking help felt that their needs were a burden rather than a valid medical concern. Conversely, when staff members did show understanding—by dimming a light, offering a quiet space, or simply speaking in a calm, clear voice—it made a profound difference. These small acts of accommodation often allowed the patient to stay, to communicate effectively, and to receive proper care.
The researchers also spoke with caregivers who support individuals with sensory sensitivities. Their accounts mirrored those of the patients, often describing even more intense reactions, including agitation, anger, or physical meltdowns. Caregivers described the exhausting work of preparing for a visit, bringing noise-canceling headphones or fidget toys, and acting as a buffer between the patient and the chaotic environment. They noted that the fear of these sensory experiences sometimes led the people they cared for to hide their illnesses or injuries, refusing to seek help until a condition became critical.
In the end, the study suggests that the barrier to healthcare for these individuals is not a lack of desire to get well, but a built environment that is hostile to their nervous systems. The participants offered practical, often low-cost solutions: quiet waiting areas, the ability to wait outside or in a car, dimmable lighting, and clear communication about what to expect before a procedure begins. They also emphasized the need for staff training, not just to make physical changes, but to foster an attitude of acceptance and empathy. The findings indicate that when healthcare providers recognize sensory sensitivity as a real and impactful experience, they can unlock better health outcomes. By making the environment less hostile, the system can ensure that the people who need care the most are not driven away by the very place meant to heal them.
