SENSORY OVERLOAD AND OVERSTIMULATION

Sensory Overload and Overstimulation - 

Sensory overload, or overstimulation, in autistic individuals refers to a condition where the sensory stimuli in their environment become overwhelming and lead to a heightened and often distressing response. Autistic individuals may experience difficulties in processing and regulating sensory information, and various sensory stimuli—such as sights, sounds, smells, textures, and tastes—can become intensified or overwhelming.

Key characteristics of sensory overload in autistic individuals include:

1. Intensified Sensory Perceptions: Autistic individuals may experience heightened sensitivity to sensory stimuli. For example, sounds that may be tolerable to others could be perceived as overly loud and disruptive.
2. Difficulty Filtering Information: Autistic individuals may struggle to filter and prioritize sensory input, leading to a sense of being bombarded by various stimuli simultaneously.
3. Physical and Emotional Responses: Sensory overload can manifest in both physical and emotional reactions. Physically, individuals may exhibit behaviours like covering their ears, closing their eyes, or seeking a quiet and dimly lit space. Emotionally, they may become anxious, agitated, irritable, or even experience meltdowns or shutdowns.
4. Overwhelmed Nervous System: The nervous system of autistic individuals may become overwhelmed, affecting their ability to concentrate, engage in activities, or interact with others.
5. Individual Differences: It's important to note that sensory experiences vary widely among autistic individuals. What is overwhelming for one person may not be as intense for another. Additionally, sensitivities can differ across different sensory modalities.
6. Triggers: Certain stimuli or environments may act as triggers for sensory overload. For example, crowded and noisy spaces, bright lights, strong smells, or unexpected changes in routine can contribute to overstimulation.
