What is Day of Sensory Overload?

Day of Sensory Overload is observed every year on June 23. It brings attention to the experience of sensory overload, a condition in which the brain receives more input from the senses than it can process. The day highlights how overwhelming everyday environments can be for people who are hypersensitive to stimuli like noise, light, touch, smell, or movement.

This day is especially relevant for people living with conditions such as acquired brain injury, autism, ADHD, or sensory processing disorder. But sensory overload can affect anyone, temporarily or chronically, particularly in high-stimulus environments. Day of Sensory Overload calls for understanding, recognition, and better accommodations in society.

History and Origin

Day of Sensory Overload was initiated in the Netherlands by the organization Hersenletsel-uitleg, a platform focused on raising awareness about acquired brain injuries and neurological conditions. The first observance took place to shed light on an often invisible struggle: how sensory overload affects daily functioning, relationships, and health.

The choice for June 23 was symbolic. It reflects the need for clear, seasonal communication when symptoms often flare due to warmer weather, increased outdoor activity, and social obligations. Since its introduction, the day has gained traction among advocacy groups, care professionals, and individuals affected by sensory overload, not only in the Netherlands but increasingly across borders.

The goal of the day is twofold: to give voice to people who struggle with overload in silence, and to educate the wider public and policymakers about the need for better support systems.

Why is Day of Sensory Overload important?

Day of Sensory Overload is important because it acknowledges a reality that is often misunderstood or completely ignored. Many people experience deep discomfort, pain, or confusion in ordinary situations like supermarkets, public transport, or loud social gatherings. When this is dismissed or overlooked, it can lead to isolation, burnout, or worsening symptoms.

By recognizing this condition, the day gives people the language and platform to explain their needs. It also pushes society to become more inclusive by promoting quiet zones, flexible spaces, and more thoughtful design in public life. Awareness is not a luxury. It’s a foundation for dignity, understanding, and health.

This day creates a space for validation and solidarity. It tells those affected that their struggle is real and that it’s okay to protect their boundaries. In doing so, it opens the door to more humane and responsive environments that respect everyone’s sensory limits.
