Overstimulation happens when your brain gets hit with more sensory information than it can handle. The lights are too bright, sounds are too loud, your clothes feel itchy, and even the smallest tasks seem impossible to focus on. For some people, overstimulation happens occasionally, like after a long day in a noisy environment. But for others, especially those with autism, ADHD, sensory processing disorder (SPD), or anxiety, it can be an everyday challenge.
What Is Overstimulation?
Overstimulation (or sensory overload) happens when your senses are bombarded with too much input at once, making it difficult to process information, focus, or stay calm. Think of it like a traffic jam – too much coming in at once, causing a mental gridlock.
This can look like:
-
Feeling anxious, irritable, or overwhelmed
-
Struggling to tune out background noise
-
Wanting to escape from a crowded or busy space
-
Becoming emotionally reactive over small things
-
Feeling physically tense, dizzy, or exhausted
Causes of Overstimulation
Several things can trigger sensory overload. Here are some of the common external factors (things in your environment) and internal factors (your mental and physical state):
Common Triggers Include:
-
Loud noises: Busy streets, concerts, alarms, or crowded places
-
Bright or flickering lights: Fluorescent bulbs, flashing screens, or sunlight glare
-
Strong smells: Perfume, cleaning chemicals, or certain foods
-
Uncomfortable clothing or textures: Tags, seams, or rough fabrics
-
Information overload: Too many tasks, notifications, or conversations at once
-
Chronic stress or anxiety: Making you more sensitive to everyday stimuli
-
Lack of sleep: Lowering your tolerance for sensory input
-
Technology overuse: Staring a screens all day can overstimulate your eyes, brain and nervous system
Sometimes, overstimulation builds up slowly throughout the day. Other times, it can hit all at once, leaving you feeling completely overwhelmed.
Sensory Overload Symptoms and Signs of Overstimulation
Recognizing the signs of overstimulation can help you act before it becomes overwhelming.
Emotional Symptoms:
-
Feeling anxious, irritated, or restless
-
Becoming easily overwhelmed by normal situations
-
Needing to withdraw from social settings
-
Sudden mood swings or emotional outbursts
Physical Symptoms:
-
Headaches or dizziness
-
Increased heart rate
-
Muscle tension or joint pain
-
Exhaustion (even after small tasks)
Cognitive Symptoms:
-
Struggling to focus or think clearly
-
Difficulty making decisions
-
Feeling like your brain is "foggy" or shutting down
If any of this sounds familiar, your brain might be asking for a sensory break.
Linked Conditions of Overstimulation
Overstimulation isn’t just an isolated issue. It’s often linked to neurodivergent conditions that affect sensory processing and emotional regulation.
Sensory Processing Disorder (SPD)
People with SPD have trouble filtering sensory input, making everyday environments overwhelming. This can make everyday sounds, textures, and lights feel unbearably intense.
Anxiety Disorders
People with anxiety are often hypersensitive to their surroundings, making them more prone to sensory overload. Crowds, social situations, or unexpected changes can all be major triggers.
Post-Traumatic Stress Disorder (PTSD)
For individuals with PTSD, certain sensory triggers (like loud noises or sudden movements) can cause panic, flashbacks, or dissociation.
How Has Overstimulation Changed?
Life today is way more stimulating than it used to be, from social media and notifications to noisy cities and bright screens. A few factors have made sensory overload more common including:
-
Remote Work & Digital Burnout – We might be avoiding noisy offices, but now we're stuck staring at screens all day. Zoom meetings, constant notifications, and lack of real breaks can cause digital overstimulation.
-
Technology Overload – Social media, video games, streaming services—our brains are constantly processing content, often without real rest.
-
Faster-Paced Lifestyles – The world moves at a breakneck speed, and we’re expected to keep up, often with little downtime.
All of this adds up, making it more important than ever to learn how to unplug and reset.
6 Tips for Dealing with Overstimulation
So, what can you do when the world feels too much? Try these six strategies:
1. Identify Your Triggers
Pay attention to what overstimulates you. Is it bright lights? Too much noise? Social settings? Once you know your triggers, you can take steps to avoid or manage them.
2. Create a Calm Environment
Your space matters. So it’s up to you to create an environment that can filter stimuli.
-
Use noise-canceling headphones in loud places
-
Dim the lights or wear sunglasses if bright lights bother you
-
Declutter your space to reduce visual distractions
-
Set limits on screen time to avoid digital fatigue
3. Take Sensory Breaks
Give yourself time to reset throughout the day. This could be:
-
Stepping outside for fresh air
-
Sitting in a quiet, dimly lit room
-
Doing deep breathing or grounding exercises
4. Use Sensory Tools
Fidget toys, weighted blankets, or noise-blocking earbuds can help reduce sensory overload. Find what works best for you.
5. Move Your Body
Gentle movement (like stretching, pacing, or rocking), breathing exercises, meditation, or even just closing your eyes for a moment can help release built-up tension and reset your nervous system.
6. Set Boundaries
It’s okay to say no to overwhelming situations! Whether that means:
-
Leaving a loud event early
-
Taking a break from social media
-
Setting work/school boundaries to avoid burnout
You don’t have to push through overstimulation. Prioritize your well-being.
FAQs About Overstimulation
Q: What Does Being Overstimulated Feel Like?
A: It feels like sensory overload – too much happening at once, making it hard to focus, stay calm, or process information. You might feel anxious, irritated, or exhausted.
Q: Is Overstimulation a Bad Thing?
A: Not always! Some people need extra sensory input to stay engaged (like ADHDers who stim to focus). The problem is when too much input causes stress or anxiety.
Q: How Do You Calm Down an Overstimulated Person?
-
Remove excess stimulation (lower lights, reduce noise, create space)
-
Encourage grounding techniques (deep breathing, fidgeting, movement)
-
Validate their experience instead of minimizing their discomfort
Q: How Do You Explain Overstimulation to Someone Who Doesn't Get It?
A: Compare it to having too many tabs open on a computer. At some point, the system crashes because it can’t process everything at once.
Should I Push Through Being Overstimulated?
Overstimulation is real, frustrating, and sometimes exhausting. Whether it’s noise, lights, textures, or social situations that overwhelm you, finding ways to reduce, cope, or take breaks can help you feel more in control of your environment.
Instead of pushing through sensory overload, give yourself the space to reset and recharge.
