When people think about neurodivergence, they often focus on the brain. Attention, memory, emotions, communication, focus, or sensory processing usually dominate the conversation. Yet for many neurodivergent people, the body is just as affected as the mind.
Conditions such as ADHD, dyspraxia, autism, dyslexia, Tourette’s syndrome, and other forms of neurodivergence can influence posture, muscle tension, coordination, pain levels, fatigue, sleep, and even how a person physically moves through the world. These experiences are often misunderstood, dismissed, or incorrectly blamed on laziness, clumsiness, or lack of fitness, when in reality they can be deeply connected to the way a neurodivergent nervous system processes information.
One of the biggest examples of this is body awareness, sometimes known as proprioception. This is the brain’s ability to understand where the body is in space and how it is moving. For people with dyspraxia especially, this can be significantly affected. A person may struggle to naturally recognise when they are sitting awkwardly, tensing muscles unnecessarily, leaning unevenly, or holding tension in certain areas of the body for long periods of time.
“Nobody ever really thinks of ADHD causing physical issues for the body too.”

Over time, this can lead to chronic tightness, aches, muscle fatigue, headaches, jaw clenching, and posture problems. Many neurodivergent people describe feeling constantly “stiff” or physically uncomfortable without fully understanding why. The issue is not necessarily a lack of effort or self-care. Often, the brain simply is not automatically monitoring the body in the same way.
ADHD can contribute to this too, although often differently. Many people with ADHD live in a state of nervous system dysregulation. Their bodies can remain in a heightened stress response for long periods, particularly when overwhelmed, overstimulated, anxious, or mentally overloaded. This can result in tight shoulders, clenched jaws, shallow breathing, stomach tension, migraines, and physical restlessness.
Some people with ADHD also struggle to notice physical needs until they become extreme. They may not realise they are thirsty, hungry, exhausted, tense, or uncomfortable until the body is already under strain. Hyperfocus can make this even worse. A person may sit in the same position for hours without noticing, only to stand up in significant pain afterwards.
Sleep can also be heavily impacted. Neurodivergent nervous systems often struggle with regulation and transitions, meaning the body may find it difficult to fully relax at night. Racing thoughts, sensory sensitivity, restless legs, muscle tension, or difficulty “switching off” can all contribute to poor quality sleep. Over time, this exhaustion can increase inflammation, worsen pain sensitivity, and create a cycle where both the mind and body become overwhelmed.
“I always wondered why I’d come back from every holiday or day trip feeling sick. I had no idea it was nervous system regulation issues.”

Sensory processing differences can add another layer. Some neurodivergent individuals are hypersensitive to physical sensations, while others may be under-responsive to them. A person might intensely feel discomfort from clothing seams, noise, heat, or physical touch, while simultaneously failing to notice injuries, posture strain, or developing muscle tension. This mismatch can sometimes make healthcare difficult too, because symptoms may not present in expected ways.
There is also growing recognition of the overlap between neurodivergence and physical health conditions. Research and lived experiences suggest increased rates of hypermobility, chronic pain conditions, gastrointestinal issues, fatigue disorders, migraines, and autonomic nervous system difficulties among neurodivergent populations. While not every neurodivergent person experiences these issues, the connection between the nervous system and physical health is becoming harder to ignore.
Importantly, this does not mean neurodivergence is “causing” weakness or poor health. Rather, it highlights how closely connected the brain and body truly are. If the nervous system processes the world differently, it makes sense that movement, tension, coordination, stress responses, and physical regulation may also look different.
“The physical effects of neurodivergent conditions should not be ignored.”

Unfortunately, many neurodivergent people grow up internalising shame around these physical struggles. They may be labelled lazy, dramatic, awkward, unfit, or careless. A child with dyspraxia may be criticised for slouching or poor coordination. An adult with ADHD may blame themselves for chronic tension and exhaustion. Yet many of these difficulties are neurological, not moral failings.
Awareness is important because understanding the cause can change how people support themselves. Physiotherapy, occupational therapy, nervous system regulation strategies, movement breaks, sensory supports, posture awareness, stretching, hydration, and rest can all help reduce physical strain. Equally important is self-compassion. Many neurodivergent people have spent years fighting against their bodies instead of understanding them.
The conversation around neurodivergence needs to move beyond the idea that it only affects thoughts and behaviour. Neurodivergence is not just something that exists “in the mind.” It is experienced through the entire body. For many people, recognising that connection can finally help explain years of unexplained tension, pain, fatigue, and physical overwhelm.
Sometimes the body has been speaking all along. The problem is that nobody realised it was part of the neurodivergent experience.
