I saw this posted in a large Neurodiversity group and I thought, I can answer all of those. Most of these questions are answered by nervous system science!
Autistic people have more sensitive nervous systems, so these become a problem for us easier than the general population. We're the "canaries in the coal mine" which means our threshold for reacting to negative stimulus is lower than average.
- Nervous system state strongly impacts if and how caffeine works. If you're already depleted, caffeine cannot magically create new energy. Caffeine tells our body to borrow from our energy stores for tomorrow and next week and next month, and eventually there is no energy available no matter how much caffeine screams "give me the energy." There are also genetic metabolism differences that affect how fast or slow we process caffeine.
- Most gastro problems are caused by nervous system imbalance and/or hypermobility. IBS-D is associated with fight/flight responses and adrenaline surges where gut motility happens too fast. IBS-C is associated with freeze/shutdown responses where gut motility just stops. Combination IBS can be from flipping between these two nervous system states. Hypermobility predisposes for allergies and food sensitivities because it makes the gut wall weaker and stretchier.
- There's a cluster of 3 genes that is usually inherited together - one codes for Autism or ADHD or similar, one codes for hypermobility, and one codes for immune hyper-activation. This is why so many Autistic people have chronic fatigue syndrome, POTS, MCAS, gluten/dairy/soy sensitivities, chemical & fragrance sensitivity, oral allergy syndrome, and many other autoimmune conditions.
- Stims meet tons of neurological needs. Repetitive motions create dopamine. Many stims are vagus nerve activating activities.
Being sensory seeking works for our brains because checking for sensory input is how our nervous system assesses for safety. For example, if we don't get enough auditory stimulation, our body might believe that our ears don't work anymore and that's scary and stressful to our subconscious. But if we can hear stuff, then the body is like: yep ears work, no worries there.
Proprioceptive sensation is one that easily goes offline for a lot of us. Without knowing where we are in space, it's hard to even know we exist. Moving our body in space tells our nervous system that our hands and feet do actually exist.
- Around 80% of the Autistic community identifies as LGBTQ+. If you are Autistic, you are likely to be outside of the social norm in more areas than just neurotype.
- The biggest thing that Autistics do better than NTs is bottom-up processing. We observe many small details and use those to build complex big pictures. NTs could never. They do top-down processing. NTs approach everything with preconceived ideas of what is expected and then fill in details from there.
Let me know if you have more questions about the Autistic experience! I don't know if I'll be able to answer all of them here, but they will inform future post topics.
🦎 My year long-course, 50 Vagus Exercises in a Year is enrolling now! We're exploring natural nervous system support, while honoring individual pacing and considering neurodivergent differences.
The exercises are taught through short videos, with a monthly Q&A session on zoom, and several more ways to learn with me, including a copy of my eBook when I finish it.
Paying to participate is optional. There's a sliding scale option and lots of free scholarship spots. My goal is to change the world with nervous system education and I don't beleive in gatekeeping this info.
