brain fog MS

Ah, summer. Sun, ice cream, holidays… unless you’ve got multiple sclerosis. Then it’s basically the devil turning the thermostat up just to watch you squirm.

Welcome to Uhthoff’s phenomenon — or as I call it, “boiling alive in your own nervous system.”

What the Hell Is It?

Uhthoff’s phenomenon is when heat makes your MS symptoms worse. Not permanently, just temporarily. But temporary doesn’t mean pleasant — it means your body throws a tantrum until you cool the hell down.

Why? Because MS already stripped the insulation (myelin) off your nerves. Heat makes that damage even more obvious. It’s like taking a half-broken wire and then running extra current through it — sparks, short circuits, total chaos.

Triggers: The Everyday Tortures

Hot weather → 25°C feels like the Sahara.

Exercise → five minutes of effort and I’m a puddle.

Hot showers or baths → who knew basic hygiene could become extreme sport?

Fever → as if being sick wasn’t enough.

Sitting in a stuffy room → congratulations, you just bought a ticket to hell.

What It Feels Like

Pick your poison:

Blurred vision — like someone smeared Vaseline over your eyes.

Weakness — your legs forget they’re supposed to be legs.

Balance — wobbly as a drunk pigeon on roller skates.

Fatigue — next-level exhaustion, like gravity tripled overnight.

Brain fog — thoughts move slower than dial-up internet.

All your regular MS crap, amped up by heat.

The (Small) Mercy

The only good news? It’s temporary. Once you cool down, things usually settle back to “normal” (whatever your personal version of normal is). You’re not getting worse long-term — you’re just being tortured in the moment. Lucky you.

Coping (aka Not Melting to Death)

Stay hydrated (yes, I know, bladder hell — but dehydration makes it worse).

Fans, cold packs, cool showers.

Avoid heat like it’s an ex who still owes you money.

Build your life around shade and air-con if you can.

Basically: treat yourself like a vampire — avoid the sun, keep cool, drink fluids, and hope the day doesn’t cook you alive.

Why Write This?

Because no one tells you about Uhthoff’s until you’re the one keeling over in the heat. Doctors might brush it off like, “Oh, just avoid hot weather.” Yeah, thanks genius — let me just move to the Arctic.

The reality is: this is part of the MS package deal. It’s crap, but it’s survivable. And if nothing else, talking about it means the rest of us don’t feel like we’re losing the plot when our bodies shut down on sunny days.

So next time you see me looking like a melted candle in a conservatory, know this: it’s not laziness, it’s not in my head — it’s just Uhthoff’s. And it can piss right off.

I write in ink and fury, in breath and broken bone.
Through storm and silence, I survive. That is the crime and the miracle.

Sunday again. My head feels like it’s trying to blow itself off my neck. The conservatory is a sauna from hell, pushing close to 100 degrees. I’m basically rotisserie-roasting in my wheelchair, waiting for the fridge and freezer to finally explode in sympathy. Their groaning is the soundtrack of my life.

A rare visitor stopped by this weekend. Strange thing, visitors — they get fewer as the years pile up, and before you know it, you’re “that forgotten bloke.” Of course, part of it’s my fault. I didn’t want people seeing me like this — a creaking neck that sounds like snapping twigs, heart palpitations strong enough to rattle furniture, eyes streaming like cheap taps, throat raw enough to sand wood. The whole freakshow. Welcome to the Sunday matinee.

And then there’s the heat. Heat and MS are the perfect lovers — clingy, suffocating, and guaranteed to leave you wrecked. When the temperature climbs, the nervous system basically goes on strike. Muscles weaken, balance evaporates, and my brain decides it’s time to reboot itself every ten minutes. Hello brain fog, goodbye memory. The world feels twice as heavy and I move half as fast. Some people call it “Uhthoff’s phenomenon.” I call it being boiled alive in your own juices.

Hydration, of course, is supposed to be the saviour. Drink more water, they say. Right. Easy advice when you don’t have bladder problems that make you live like a hostage negotiating toilet breaks. Water in, waterfall out. Still — dehydration just makes everything worse. Thick blood, pounding head, and an MS body that’s already halfway to meltdown. So I chug when I can, and pay the price when I can’t make it in time. Life’s full of trade-offs.

So what’s left? Medical Mary Jane and Gregorian chants. Sounds ridiculous, but it’s the closest thing I’ve got to therapy. Weed dulls the edges, chant quiets the chaos, and words on this page act as pressure release — raw, unfiltered, sarcastic truth. I know most people don’t want to hear about diarrhoea, pissing yourself, or falling apart in the heat. But some will. Maybe 10, maybe 20 people. And those are the people who get it. That’s who I write for.

Because at the end of the day, there’s no neat bow to tie on this. MS is ugly, sweaty, isolating, and full of brain-melting days where the stress sits on your chest like a fat cat. And yeah, I feel forgotten sometimes. Weird. Different. Alone. But if writing this makes one other person feel less alone in their own meltdown, then maybe it’s worth frying in this bloody hotbox.

I write in ink and fury, in breath and broken bone.
Through storm and silence, I survive. That is the crime and the miracle.
