Why are people so desperate to claim that neurodivergent people don't struggle more with certain things?
Yes, the hot weather is uncomfortable for most people. That doesn't mean some people don't struggle more because of many different conditions (pregnancy, menopause, being very old or very young etc...).
Autism can cause issues with interoception. This means some autistic people don't realise that they are overheating or dehydrated as quickly as neurotypical people. They therefore don't get the signal to take action to cool down or drink water, which can cause them to further overheat.
Sensory issues can also make being too hot, or too cold, more uncomfortable for some autistic people. This isn't limited to the sensation of actually being hot (or cold), it can also include sensory aversions to being sweaty, bright sunlight, wearing weather appropriate clothing (one of my family members needs the sensory input of a sweatshirt to regulate... that's not feasible in 30 degree heat without seriously overheating), even the feeling of a fan can cause sensory overwhelm in some people.
Many antidepressants actually cause your body to struggle more with regulating body temperature. Autistic people (especially women) are more likely to be prescribed these medications.
Acknowledging that some people struggle more than you doesn't take away the fact that you're hot and bothered.
