Greetings Earthlings! 🙂

This week, I’d like to delve into an somewhat unusual subject- how weather impacts people with autism.

I know what you’re thinking, she’s run out of things to say so she’s falling back on Ireland’s favourite topic of conversation 😛

Joking aside, while this might seem like a silly topic, weather can have a surprisingly significant effect on autists both psychologically and physiologically. Coping with the sensory impact of extreme weather conditions, the lack of predictability and issues with change, and routine disruptions surrounding seasonal weather transitions can all be overwhelming. Something so simple as an unexpected shower or a really hot day could potentially trigger a meltdown (have certainly come to the brink myself when I’ve been overheated on occasion- although granted this was often coupled with hunger or exhaustion 😛 ).

Thankfully, a life spent living in the highly unpredictable Irish climate where one often experiences all four seasons in a single day has made me immune to most fluctuations, but for many others the weather poses daily challenges.

Sensory issues aside, many studies have noted some behavioural changes in autists under certain weather conditions. Research has found that autists are particularly susceptible to drops in atmospheric/barometric pressure i.e. the weight of air pressing down on us from the earth’s atmosphere. When pressure is high, we have dry, sunny weather; when pressure is low, rain and dark clouds. This drop in pressure results in a drop in blood oxygen levels. Consequently, the body adjusts heart rate and blood pressure to adapt to these changes which can interfere with brain activity. This often leads to mood swings, increased impulsivity and autists are more likely to indulge in destructive behaviours (especially for those with ADHD).

In addition to this, if you’re anything like me, drops in barometric pressure may also make you very sleepy and sluggish due to the fluctuations in brain oxygen levels (nice to know why taking naps has become somewhat of a pastime in recent weeks staring up at a perpetually wet and grey sky 😛 ).

There’s no clear reason why low pressure impacts autists more than neurotypicals, but given that our brains are wired differently, pressure related fluctuations in brain activity are bound to have more of an impact. Moreover, given the impact of deep pressure stimulation and it’s calming effect on the autistic nervous system, perhaps this could explain why our brains go a little bit crazy in response to drops in atmospheric pressure.

Hope you enjoyed this post dear Earthlings! 🙂

Have a lovely weekend!
