Sensory sensitivity to touch refers to an increased or heightened response to physical contact, textures, or pressure on the skin. People with touch sensitivity may notice discomfort, irritation, or strong awareness from sensations that others experience as neutral or barely noticeable.

This article provides an education-only overview of sensory sensitivity to touch, explaining what it is, common characteristics, and how it can affect daily life. It does not provide medical advice, diagnosis, or treatment.

Sensory sensitivity to sound refers to heightened awareness or responsiveness to everyday noises that others may find neutral or easy to ignore. People with sound sensitivity may perceive certain sounds as louder, more distracting, uncomfortable, or overwhelming, even when the volume is not objectively high.

This sensitivity exists on a spectrum and can vary from mild annoyance to significant discomfort. It is a descriptive term, not a diagnosis, and is commonly discussed in educational and general health contexts.

Sensory sensitivity to light refers to an increased responsiveness or discomfort when exposed to certain levels or types of light. It is a general, non-clinical term used in educational contexts to describe how some people perceive light more intensely than others.

This sensitivity can affect how comfortable a person feels in everyday environments, especially those with bright, flickering, or harsh lighting.

Sensory discomfort refers to physical or mental unease that arises when the nervous system reacts strongly to sensory input. This input can involve sound, light, touch, temperature, smell, taste, or visual stimulation. Sensory discomfort is not a diagnosis, but an educational term used to describe how certain sensations may feel overwhelming, irritating, or difficult to tolerate.

People experience sensory discomfort in different ways and intensities. What feels neutral to one person may feel uncomfortable or distracting to another, depending on sensitivity, environment, and context.

Neural overstimulation refers to a state in which the nervous system receives more sensory or cognitive input than it can efficiently process at a given time. This can occur when the brain is exposed to continuous, intense, or overlapping stimuli without sufficient opportunity to rest, filter, or reset.

The nervous system is designed to take in information from the environment, interpret it, and respond appropriately. Neural overstimulation happens when this input exceeds the system’s short-term processing capacity, leading to mental or sensory overload rather than effective response.

This concept is informational and descriptive, focusing on how the nervous system functions under high input conditions rather than on diagnosis or treatment.

Brain-body communication refers to the continuous exchange of signals between the brain and the rest of the body that allows movement, sensation, regulation, and awareness to function together. This communication helps coordinate how the body responds to internal needs and external environments in real time.

Rather than operating separately, the brain and body function as an integrated system, constantly sending and receiving information to maintain balance and support daily activities.

Reaction time change refers to a noticeable difference in how quickly a person responds to stimuli, such as sounds, visual cues, or physical events. Reaction time is the interval between sensing something and responding to it, and changes can occur gradually or suddenly depending on various factors.

Reaction time change is considered a neurological and sensory experience, not a disease. It describes variation in response speed rather than a specific medical condition.

Neural processing speed refers to how quickly the brain receives, interprets, and responds to information. It describes the pace at which signals travel through the nervous system and how efficiently the brain processes sensory input, thoughts, and instructions.

In neurological and sensory health education, neural processing speed helps explain differences in reaction time, thinking speed, and how quickly people can understand and respond to what is happening around them.

Neurological fatigue is a term used to describe a feeling of mental or nervous system exhaustion that affects thinking, focus, sensory processing, or cognitive effort. It often feels different from physical tiredness and may involve difficulty concentrating, processing information, or sustaining mental tasks.

Neurological fatigue is not a diagnosis. It is a descriptive concept used in educational and neurological discussions to explain how the brain and nervous system can become overwhelmed or overworked.

Sensory awareness refers to the ability to notice, recognize, and interpret sensory information from the body and the surrounding environment. This includes awareness of sights, sounds, smells, tastes, touch, movement, and internal bodily sensations.

Sensory awareness is a descriptive concept used in neurological, sensory, and educational contexts. It helps explain how people perceive and respond to sensory input as part of everyday experience, rather than serving as a diagnosis or medical condition.
