Does your sleep position mimic a prehistoric predator? You might have heard the term "T-Rex arm sleeping" thrown around in discussions about quirky sleep habits. And, no, it does not involve suddenly morphing into a dinosaurian hybrid during slumber. Rather, T-Rex or dinosaur sleeping is simply the colloquial term for the way some people position their arms while they sleep, curling them inward close to the chest.

This is superficially similar to how, you guessed it, a T-Rex would have positioned its tiny arms. It’s an observation that has gained recent popularity on social media like TikTok. But just what does it mean for the sleeper, and their health, if they adopt such a saurian stance?

The phenomenon of T-Rex sleeping has sparked curiosity and even concern, with some wondering if it might be linked to specific health conditions. A significant point of discussion is the connection between T-Rex arm sleeping and neurodivergence. Many people on the autism spectrum or those with ADHD often adopt this sleeping position.

It is broadly hypothesized that this posture can provide a sense of comfort and security, especially for those dealing with sensitivities in regard to their senses. Experts note that this position can help individuals feel grounded in a way, and manage sensory input more effectively.

Despite popular belief, sleeping with T-Rex arms is not a definitive sign of neurodivergence. Sleep experts emphasize that this position is simply a comfortable one for many people, helping them feel secure and relaxed.
