Managing an Autoimmune Flare Up After Traveling

Travel is amazing, but if you live with an autoimmune disease, you already know it can come with a price. 

The jet lag, late nights, packed schedules, new foods, and sheer excitement are enough to send your immune system into overdrive — and suddenly you’re dealing with an autoimmune flare up just when you wanted to be reliving the highlights of your trip.

I’ve been there — recently in Donegal, Ireland, for a travel conference that had me running on 16- to 20-hour days, minimal rest, and more activity than my body is built for. 

By the time I got home, I crashed hard: exhaustion, light sensitivity, noise sensitivity, the works. And that’s on top of trying to keep up with kids, school runs, and regular life waiting for me back home.

If this sounds familiar, you’re not alone. In this post, I’ll share what triggered my flare, how I managed it once I got home, and practical tips that make traveling with autoimmune disease less overwhelming. 

My goal isn’t to tell you to avoid flares altogether — because sometimes they happen no matter how careful you are — but to show you how to plan for them, recover from them, and still enjoy your trip without guilt.

Conferences are long, loud, and packed with things you don’t want to miss — and this one was no exception especially since it was in my favorite country ever, Ireland. 

My normal rhythm is in bed by 8:30 and up by 6:00. In Ireland, jet-lag had me waking up at 5:00 a.m. and FOMO / networking keeping me out until close to 12:30 at night. That’s not sustainable for anyone, let alone someone managing an autoimmune disease.

Before the conference even began, my body was showing me warning signs: I couldn’t eat more than one meal a day, sleep was down to a few hours at best, and rashes showed up under my eyes and on my hands.

I didn’t use my two “free” days before the conference to actually rest. 

Instead, I gave in to FOMO and crammed in castles, ruins, and scenic drives. It was incredible, but by day two I was already run down. Add in taxis, long rides, and late nights, and my body didn’t stand a chance.

The conference itself was amazing, but it was nonstop: 

  • 🥃 a whiskey distillery tour, 
  • 🎶 traditional music at Leo’s Tavern (where I ended up on stage dancing to the Rattlin’ Bog), 
  • 🍲 Michelin-starred food, 
  • 🍻 more whiskey and beer tours, and 
  • 🎉 days capped with VIP parties. Fun? Absolutely. 

Gentle on my immune system? Not even close.

Then came the Fanad Head Lighthouse climb — endless stairs in the rain and wind. The views were worth it, but the cold exposure tipped things further. By the time the closing party rolled around, I was running on fumes.

When I got home, the crash hit hard. Extreme fatigue, fevers, nausea, light and noise sensitivity, even touch sensitivity — all piled on top of the neuro-fatigue I already manage. 

Day 1 back, I barely made it out of bed. Day 2, I had to drag myself into mom-mode with school runs and lunch boxes, but my body was in full revolt. I’m going on Day 3, barely at 40% capacity.

Travel is exciting, but it’s also a minefield of flare triggers. Some of them are obvious, and some sneak up on you in the middle of the trip when it’s already too late. 

Here are the ones I’ve learned to watch for:

  • Jet lag and disrupted sleep — Different time zones and late nights are almost guaranteed when traveling. Missing your regular sleep window adds up fast.
  • Overexertion — Stairs, long walks, or standing on your feet all day will push your body past its limit quicker than you think.
  • Food and alcohol — Even a couple of drinks at a tasting tour or a change in diet can send your immune system reeling.
  • Weather extremes — Cold, damp, heat, or sudden changes in temperature can trigger inflammation and fatigue.
  • FOMO — The hardest one to avoid. Skipping rest to “see everything” almost always guarantees a flare.

What USUALLY helps me is following a “one big thing a day” rule — planning for just one major activity and leaving the rest of the day open for recovery or low-key exploring.

Sometimes I’ll even build in a “rest sandwich” — rest before and after a big event so my body has a chance to bounce back.

My body never stands a chance during these travel conferences, but that’s okay. I knew I would crash going in and planned for rest after my trip (except for driving kids to and from school).

It doesn’t erase the risk of a downturn, but it makes the trip a little more manageable and gives your body a fighting chance.

When I get home from a trip, I already know what’s waiting for me: the crash. The best thing I can do is prepare for it and give myself as much recovery time as possible. This isn’t just about managing a flare — it’s about how to recover from an autoimmune disease flare while dealing with everything life throws at you post-trip.

Here’s how I manage the fallout when an autoimmune flare hits after traveling.

I block off at least a week after a trip with no big appointments, no major deadlines, and nothing that requires me to be “on.” It’s not wasted time — it’s what makes future travel possible.

My go-to is a dark, quiet room with no stimulation. Phone on silent, lights off, and no background noise. The less input my body has to process, the faster I bounce back.

Even though I hate salt, I make myself get electrolytes and balance it with simple, nourishing foods. Nothing fancy — just enough to keep my body fueled without adding extra stress. I’m also drinking a ton of water with my Buoy rescue drops that reset my system in less time.

I keep small comforts ready: blackout curtains, weighted blanket, heating pad, noise-canceling headphones, hydration drops, and freezer meals. Having those in place makes surviving a flare a lot less miserable.

It’s tempting to play catch-up the second I feel a little better, but that always backfires. I pace myself with school runs, errands, and chores, and remind myself that “rest now” is better than “bedridden later.”

Traveling with an autoimmune disease doesn’t mean you have to stay home, but it does mean you have to plan differently. Here are the strategies I’ve learned (sometimes the hard way). 

I should have rested on my two “free” days in Donegal. Instead, I packed them with castles, ruins, and scenic drives. Worth it? Yes. Smart? Not really. Now I schedule actual downtime before and after big events so my body can catch up.

Conferences are intense. Between distillery tours, lighthouse climbs, and late-night parties, my days ran 16–20 hours. Next time, I’ll stick to one major activity a day and leave room for breaks.

Easy access to food and rest spaces matters more than fancy extras. After climbing endless stairs at the lighthouse, I learned how important it is to have somewhere comfortable to crash afterward.

Always in your carry-on, with extras if possible. The last thing you want is to be stuck in another country waiting for a pharmacy to open.

Rest isn’t wasted travel time — it’s what keeps the trip doable. My body reminded me of that the hard way when I ignored it. Now, I block in days where the only plan is to eat, rest, and maybe wander slowly.

Traveling with autoimmune disease is all about balance. For anyone traveling with chronic illness, planning downtime isn’t optional — it’s what makes the trip possible. 

You can still say yes to the castle climbs and the late-night music sessions — just make sure you’re also saying yes to the downtime your body demands.

The flare was brutal. I came home exhausted, light-sensitive, and barely functional. My kids wanted to talk, and I could hardly keep my eyes open. That part isn’t fun, and I won’t sugarcoat it.

But the trip? Worth every second. I danced to traditional music in a Donegal pub, climbed a lighthouse, ate food from a Michelin-starred chef, and laughed with new friends until the early hours. Those moments are what I’ll remember — not the week I spent in a dark room recovering.

Travel with autoimmune disease isn’t about avoiding flares completely. Sometimes, no matter how carefully you plan, they’ll happen. The key is knowing your limits, preparing for the crash, and deciding for yourself when the experience is worth the price your body makes you pay.

For me, Donegal was.

Managing an immune system crash post-travel takes planning — before, during, and after the trip. You don’t need to figure it all out at once, but you do need a plan that gives your body space to recover.

Start with something simple: build slow days into your itinerary. My How to Have a Slow Day eBook walks you through how to add rest to your travel without guilt, so you can come home with memories instead of burnout.

And if sensory overload is your biggest trigger, keep an eye out for my upcoming Sensory Reset Day guide, designed to help you calm the chaos when light, noise, and fatigue hit all at once.

Your next trip doesn’t have to be flare-free — but it can be more manageable. Take the tools, plan your buffers, and give yourself permission to travel on your terms. 

Post-travel recovery is its own challenge. If you struggle with post-travel fatigue and flare management, know that your body isn’t broken — it’s just asking for rest.
