Sensory Series: Sensory Joy and Overload at Christmas

Christmas in Australia arrives with the buzz of cicadas, the smell of sunscreen mixing with barbecue smoke, the harsh brightness of summer sun bouncing off tinsel, and the peculiar disconnect of winter imagery in forty-degree heat.

For many Autistic people, navigating Christmas means managing not just the usual holiday intensity, but the added sensory challenges of celebrating in the middle of summer.

But it’s also important to acknowledge something else: the sensory experience of Christmas isn’t universally overwhelming. Autistic people experience sensation across a wide and diverse spectrum — some find deep joy in the heat, the beach energy, the loud music, or the bright lights. For others, those same sensations are painful or exhausting. Sensory joy and sensory overload can (and often do) coexist.

Understanding how our sensory systems navigate this unique Australian Christmas helps us create celebrations that actually fit our environment and our needs.

The Unique Sensory Signature of an Aussie Christmas

Australian Christmas doesn’t just transform spaces — it transforms them while fighting against the climate.

Shops blast both Christmas music and arctic air conditioning. Homes fill with decorations while fans whir constantly. For those on the coast, the beach becomes a gathering place where sand, salt, sun, and social expectations collide.

Even the food fights tradition — hot roasts competing with cold seafood, pavlova melting in the heat, chocolate decorations that won’t hold their shape.

For Autistic people, this creates layers of sensory complexity. We’re not just managing Christmas overload; we’re managing it in extreme heat — with sunscreen (texture and smell), sweat (constant dampness), insects (unexpected touches and sounds), and the relentless brightness of the Australian summer sun.

Story: The Two-Season Sensory Clash

“Every Christmas, I tell myself I’ll be more prepared. But the moment I step into the shopping centre, the sensory chaos hits. The air is thick with the competing smells of perfume, food courts, and artificial pine. Carols about snowy wonderlands blare from every speaker while my body feels like it’s melting — like I’m the snowman I’m somehow meant to build in forty-degree heat.

I’m trying to choose gifts that will resonate with family and friends, but the music loops endlessly, and I lose track of what I’ve already picked up. The crowds press in — people brushing past me, the hum of hundreds of conversations bleeding together into one overwhelming soundscape. I can feel the clock ticking; there’s so much to do, and my brain starts racing to keep pace with the noise around me.

My skin prickles from the constant movement and heat. The fluorescent lights glare down, reflecting off shiny decorations, adding to the sense that everything is too much, too bright, too close. By the time I finally leave, my head throbs with music and scent, my body sticky with sweat, my thoughts scrambled.”

Shopping centres are just one example of how the season layers intense sensory demands onto an already overstimulating Australian summer. For some Autistic people, this environment is energising and exciting — the music, the lights, the buzz. For others, it’s a fast track to overwhelm.

These pressures don’t end when you walk out the door. The same sensory intensity follows into gatherings, meals, outdoor events, and family traditions. And that’s where the summer-specific challenges really begin — alongside the small sensory delights that make this season special for many.
