People do "T-Rex hands" (keeping arms close, elbows bent) for comfort, sensory regulation, and security, often seen in autistic and neurodivergent individuals as a form of stimming to manage overwhelm, but also in neurotypical people for grounding, like holding a pillow, though it can sometimes cause discomfort or stiffness. It's a way to create a secure, cocoon-like feeling or manage heavy limbs, but can sometimes lead to tingling or wrist issues.
The T. Rex arm sleeping position refers to a way of sleeping where the arms are bent at the elbows and held close to the body, similar to the way a T. Rex's arms are positioned. This sleeping position is not exclusive to autistic individuals, but it can be particularly prevalent among them.
This behavior can occur during excitement, stress, or sensory overload. It can also be observed during rest, particularly in children with autism, as part of T-Rex arms sleeping patterns. Parents and teachers often notice: T-Rex hands or trex hands when children are focused or overstimulated.
That's a unique little quirk for some with ADHD. It's often a form of self-soothing or proprioceptive input.
Key Highlights. T-Rex arms in autism refer to a self-regulating posture often tied to sensory sensitivities and emotional comfort. This behavior is a form of stimming that helps autistic individuals manage sensory overload and stress.
T-Rex arms may also be linked to sensory processing differences that affect how they respond to their sleep environment. While this is a common trait among the neurodivergent community, some neurotypical individuals may also sleep this way.
Around 90% of autism cases are attributed to genetic factors, meaning autism is highly heritable, with many different genes contributing, rather than a single cause, often interacting with environmental influences during early brain development, though specific environmental factors don't cause it but can increase risk. Twin studies show strong genetic links, with concordance rates between 60-90% in identical twins, and research points to complex interactions of many genes and prenatal/perinatal factors.
The ADHD "30% Rule" is a guideline suggesting that executive functions (like self-regulation, planning, and emotional control) in people with ADHD develop about 30% slower than in neurotypical individuals, meaning a 10-year-old might function more like a 7-year-old in these areas, requiring adjusted expectations for maturity, task management, and behavior. It's a tool for caregivers and adults with ADHD to set realistic goals, not a strict scientific law, helping to reduce frustration by matching demands to the person's actual developmental level (executive age) rather than just their chronological age.
T-Rex arms are a specific type of stimming behavior found in the autism spectrum. Stimming includes repeated movements or sounds. These can give comfort, help manage emotions, and handle sensory input.
The five gifts of ADHD include creativity, emotional sensitivity, exuberance, interpersonal empathy, and being nature-smart (The Gift of Adult ADD, 2008).
Why Might Neurodivergent People Sleep with Dinosaur Hands? For many neurodivergent individuals, this sleep posture serves as a form of comfort and regulation. The act of curling one's hands inward may provide a sense of security, akin to wrapping oneself in a protective cocoon before drifting into sleep.
You might have AuDHD if you experience both ADHD traits (inattention, impulsivity, hyperactivity, need for stimulation) and Autism traits (social communication differences, rigid routines, sensory issues, intense special interests), often creating internal conflict like needing routine but struggling to stick to it, or hyperfocus vs. distractibility. AuDHD (a blend of Autism Spectrum Disorder and ADHD) involves these overlapping and sometimes contradictory symptoms, leading to unique challenges like rapid burnout, intense focus, or sensory overwhelm. A formal diagnosis from a professional is needed, but self-reflection on these combined traits can guide you toward seeking an evaluation.
In neurodivergent people, T-rex arms are often a way to self-soothe and find comfort. Gentile suggests observing why someone seeks this comfort to better address their needs.
Five key signs of autism (ASD) involve difficulties with social communication, repetitive behaviors, intense interests, sensory sensitivities, and strict routines, such as trouble with small talk/eye contact, hand-flapping/lining things up, deep focus on specific topics, sensitivity to sounds/lights, and distress over schedule changes, though these vary widely.
The "6-second rule" for autism is a communication strategy where a speaker pauses for about six seconds after asking a question or giving information, giving the autistic person extra time to process it without feeling rushed, which helps reduce anxiety and allows for a more thoughtful response, reducing frustration for both parties. Instead of repeating or rephrasing, which can be confusing, you wait, and if needed, repeat the exact same words after the pause.
Autism red flags involve challenges with social communication (like avoiding eye contact, not responding to name by 12 months, lack of shared smiles/pointing) and restricted, repetitive behaviors (like hand-flapping, strong routines, lining up toys, intense fixations, sensory sensitivities, or loss of skills). Early signs in infants include no warm smiles by 6 months or no back-and-forth gestures by 12 months; regression (losing skills) is a major flag. If you notice these, seek immediate evaluation from your pediatrician.
Hand flapping is one of the most recognizable hand posturing behaviors seen in individuals with autism. It involves rapid and repetitive movements of the hands, typically with the fingers extended and the wrists flexed. Hand flapping may occur when a person is excited, anxious, or overwhelmed.
There is not just one cause of ASD. Many different factors have been identified that may make a child more likely to have ASD, including environmental, biologic, and genetic factors.
The ADHD "2-Minute Rule" suggests doing any task taking under two minutes immediately to build momentum, but it often backfires by derailing focus due to weak working memory, time blindness, and transition difficulties in people with ADHD. A better approach is to write down these quick tasks on a separate "catch-all" list instead of interrupting your main work, then schedule specific times to review and tackle them, or use a slightly longer timeframe like a 5-minute rule to prevent getting lost down "rabbit holes".
Increase stress relief by exercising outdoors—people with ADHD often benefit from sunshine and green surroundings. Try relaxing forms of exercise, such as mindful walking, yoga, or tai chi. In addition to relieving stress, they can teach you to better control your attention and impulses.
While the exact reasons are not yet clear, changes in how the disorder is defined, increases in screening, and more awareness certainly contribute to this increase. If you have any concerns about your child's development, speak to a healthcare professional about diagnostic tests.
Donald Triplett, autism's 'Case 1,' dies at 89. Triplett gained media attention for his autism later in life, and he became the face of the effort to research the lives of older adults with autism.
Is autism genetic? Research tells us that autism tends to run in families, and a meta-analysis of 7 twin studies claim that 60 to 90% of the risk of autism comes from your genome. If you have a child with autism, you are more likely to have another autistic child.
