Sensory Overload & ADHD: Symptoms, Triggers, & Treatment

What Is Sensory Overload?

Sensory overload occurs when the brain struggles to process overwhelming sensory input from sight, sounds, touch, tastes, or smells. Those with sensory issues exhibit exaggerated responses to such interactions, whether bright lights, tight spaces, or loud noises. Sensory overload can develop alongside several disorders (i.e., autism, PTSD, OCD) or as a stand-alone sensory processing disorder (SPD).

Sensory Overload & ADHD: How They’re Connected

Individuals with attention-deficit/hyperactivity disorder (ADHD) often struggle with sensory overload due to their unique neurological differences. Certain areas in the ADHD brain, including the prefrontal cortex, may be underactive, increasing the likelihood of sensory overload.

Connections between sensory overload and ADHD include:¹

• Trouble with transitions: Transitions can be challenging for those with ADHD, as they often involve different sensory stimuli. The brain must adjust and process new information when people switch from one activity, environment, or sensory experience to another. Due to a tendency toward inflexible thinking, individuals with ADHD may experience heightened reactions to these changes.
• Difficulty with emotion regulation: Emotional outbursts and difficulty managing emotions can amplify the impact of sensory overload, leading to heightened reactions to sensory stimuli.
• Inattention: Difficulty sustaining focus on specific tasks can make filtering out irrelevant sensory input difficult, leading to sensory overload.
• Hyperactivity: Hyperactive individuals may be more prone to sensory overload due to heightened arousal levels and difficulty regulating responses.
• Impulsivity: Impulsive behavior can lead to sudden exposure to intense sensory stimuli without considering potential consequences, exacerbating sensory overload.

Symptoms of Sensory Overload in ADHD

Navigating ADHD and sensory issues can be daunting. Many may wonder, “What does sensory overload feel like?” In many cases, ADHD overstimulation can be overwhelming, even debilitating.

Sensory sensitivity in adults and children can manifest as distress, anxiety, and discomfort. While some individuals with ADHD exhibit irritability or meltdowns when experiencing sensory overload, others may appear withdrawn, disengaged, or quiet. Other times, individuals may seek excessive sensory input as a coping mechanism.

Individuals with ADHD can exhibit similar sensory overload symptoms, but the expression may differ due to developmental factors. Children may display temper tantrums or difficulty self-regulating, while adults might experience heightened stress, frustration, and poor concentration when overloaded.

Common symptoms of sensory overload for adults with ADHD include:²

• Trouble focusing
• Restlessness
• Anxiousness
• Panic attacks
• Increased irritability and mood swings
• Difficulty concentrating or making decisions
• Feeling overwhelmed or on edge
• Headaches 
• Fatigue
• Avoidance of crowded or noisy environments
• Seeking isolation or withdrawing socially
• Heightened emotional responses or outbursts
• Trouble filtering out background noises or distractions

Common symptoms of sensory overload for children with ADHD include:³

• Tantrums
• Trying to hide
• Covering ears or eyes in response to stimuli
• Becoming restless or fidgety
• Refusing to participate in certain activities or tasks
• Increased emotional reactivity or outbursts
• Difficulty following instructions or staying focused
• Seeking excessive sensory input (i.e., touching everything, spinning, etc.)
• Nausea or vomiting not related to illness

Is Sensory Overload a Symptom of ADHD?

While ADHD does not directly cause sensory overload, those with the diagnosis are more likely to experience sensory issues. Children with ADHD more frequently struggle with these difficulties than their neurotypical peers.⁴ Sensory overload can also affect adults with ADHD, with prevalence and severity varying among individuals.

What Causes ADHD Sensory Overload?

Various factors can increase the likelihood of experiencing sensory issues or sensory processing disorder and ADHD, including neurological differences, environmental stimuli, and individual sensory processing abilities. Individuals with such sensitivities may feel overloaded by specific spaces, bright lights, strong smells, and unexpected changes.

For example, ADHD sound sensitivity, sensory issues with clothing, and taste aversions are common. Of course, what causes or triggers sensory overload varies significantly depending on the person, with some individuals being more sensitive to certain stimuli.

Sensory triggers for those with ADHD include:

• Touch: Certain textures, clothing tags, rough fabrics, or excessive physical contact can trigger sensory overload, leading to discomfort or agitation.
• Taste: Strong or unfamiliar tastes, extreme temperatures, or certain food textures can provoke sensory overload. These issues can contribute to food aversions or strange eating habits.
• Sound: Loud noises, chaotic environments, sudden changes in sound levels, and overlapping conversations can cause overwhelm and a need to escape the environment.
• Smell: Strong or unpleasant odors, potent perfumes, and chemical scents can be overpowering and cause nausea, vomiting, or headaches due to sensory overload.
• Sight: Bright or flickering lights, visually cluttered spaces, rapidly moving objects, or intense visual patterns can trigger sensory overload.

ADHD Sensory Overload Treatment Options

Sensory overload in ADHD is not “curable,” and treatment options are limited. Therefore, the primary focus is managing symptoms by reducing exposure to triggers and staying healthy, as fatigue and stress can exacerbate sensory sensitivity.

Research supports the effectiveness of sensory integration or occupational therapy in reducing sensory processing difficulties and improving daily functioning for ADHD-related sensory overload in adults and children.⁵

How to Deal With ADHD Sensory Overload

Addressing sensory overload can be challenging, but healthy and effective strategies can help you cope. Developing a personalized sensory diet by incorporating activities to regulate sensory input can be beneficial. Meditation for ADHD can help manage emotional responses to overwhelming stimuli. Additionally, creating a supportive and sensory-friendly environment and seeking professional guidance can empower individuals to better cope with sensory overload positively and sustainably.

Here are 12 strategies to help cope with sensory overload:

1. Speak with your healthcare provider: Healthcare providers, such as doctors, therapists, or occupational therapists, have expertise in understanding sensory processing difficulties and ADHD-related issues. They can provide you with tools for managing sensory input.
2. Identify your triggers: Identify and minimize exposure to known sensory triggers in your environment to avoid unnecessary overload. Working with a provider specializing in cognitive behavioral therapy (CBT) can help you implement thought-stopping techniques when triggered.
3. Learn self-soothing techniques: When individuals experience sensory overwhelm, their nervous system can become overstimulated, leading to heightened stress and emotional responses. Self-soothing techniques help regulate the nervous system and reduce the emotional intensity associated with sensory overload.
4. Try a sensory diet: Develop a daily routine that includes sensory activities to regulate sensory input, such as deep-pressure exercises, fidget toys, or sensory breaks.
5. Incorporate mindfulness and breathing: Practice mindfulness techniques and deep breathing exercises to manage stress and reduce emotional reactions to overwhelming stimuli. Consider trying 4-7-8 breathing or alternate nostril breathing.
6. Create a calm space: Designate a quiet and comfortable area to retreat during sensory overload to regain composure and relax.
7. Put on noise-canceling headphones: Invest in noise-canceling headphones to reduce auditory input in noisy environments or overwhelming situations.
8. Plan ahead: Anticipate potentially triggering situations and plan accordingly to minimize unexpected sensory challenges.
9. Adjust for a sensory-friendly environment: Cultivate your home or workspace by using soft lighting, neutral colors, and reducing clutter to create a more sensory-friendly environment.
10. Seek occupational therapy: Consider working with an occupational therapist experienced in sensory processing to develop personalized coping strategies and techniques.
11. Use sensory tools: Incorporate sensory tools like stress balls, weighted blankets, or chewable jewelry to help redirect and manage sensory responses.
12. Establish routines: Follow consistent daily routines to provide a sense of predictability and stability, which can be reassuring during sensory overload. Exercise and journaling can be positive additions.

When to Seek Professional Help

Individuals should consider seeking professional help when negative symptoms associated with sensory overload and ADHD significantly impact their daily lives, relationships, or overall well-being. Finding a neurodiversity-affirming therapist is essential, as they understand and respect the diverse experiences of neurodivergent folks. An online therapist directory is a great tool to help locate such a provider near you.

An online therapy platform can also be suitable for accessing convenient and accessible specialized treatment. If your symptoms require ADHD medication management, consider seeing a psychiatrist. Online psychiatrist options are available and offer flexibility for those seeking specialized care.
