overstimulation
OH-ver-stim-yuh-LAY-shuhn
/ˌoʊvərˌstɪmjʊˈleɪʃən/
The state of being exposed to excessive sensory or mental inputs, leading to exhaustion, anxiety, or an inability to focus.
Refers to a physiological state where the nervous system is overwhelmed by too many sights, sounds, or data points at once.
The story behind the word. The root of 'stimulation' is the Latin 'stimulare', which meant to prick or goad with a sharp stick (a 'stimulus' was literally a pointed stick used to drive cattle). To be 'overstimulated' is to be repeatedly pricked and poked by modern notifications until your nervous system is raw and exhausted.
Word relationships
- sensory overload: Sensory overload is a slightly more clinical term focusing on the five senses, while overstimulation can also refer to purely cognitive or emotional overload.
- understimulation: Understimulation is the state of being bored or lacking sensory input, which can also lead to restlessness.
- calm: Calm is a state of peace and low sensory input, the direct opposite of overstimulation.
Commonly confused with
- hyperactivity: Hyperactivity is an internal state of high physical energy or movement, whereas overstimulation is an external overload of the nervous system.
