Why So Many Brides Get Sick the Week Before the Wedding

In my experience as a wedding planner, I've seen what I like to call the seven-day sniffle. It's a pre-wedding cold that hits approximately 72 percent of brides. Think of it this way: while you're in full planning mode, arranging all the logistics, your body is working overtime to handle all the stress.

But the second you finally tick off the last of the to-do list and speak to your last vendor, that's when your body decides to fully relax. Your immune system goes down, and you become more prone to a cold (at the worst possible time, of course, because your wedding is a week away).

You're not alone; I've seen this happen to countless brides. And while getting a cold so close to your big day is annoying, there are ways to fix it.

The Adrenaline Crash

First, let me explain why you are more prone to getting the sniffles at what's arguably the worst possible time. Think of it this way: for more than a year, you have been experiencing a level of chronic low-grade stress, which kept your cortisol and adrenaline levels permanently high. What triggers the crash is simply the removal of stress. That moment you feel you can finally relax, your adrenaline goes down, and your body becomes more prone to getting sick. This is also known as the letdown effect, or leisure sickness, and was well studied by the Dutch psychologist Wingerhut in the early 2000s.

Wedding planners, in particular, are hit the hardest, simply because the end of the planning season is sharp and total. Your books, your floor plans, your timeline, all close at once; there's no wind-down period. Once you put that phone down, your body immediately shifts into a state of relaxation.

The Logistics of Rest

It might sound impossible because you want your big day to be perfect, but you also need to take care of yourself. Start by making sure you hand off all vendor communication by day seven so you can fully rest before the wedding. By handoff, I mean implementing ruthless delegation, not just reducing calls or replying to emails only once a day. Ask a trusted friend or a planner to handle the vendors while you relax fully for your big day.

Consider implementing an out-of-office auto-reply, which will signal finality to vendors and might lower your temptation to check in. For further peace of mind, sit down and put together a master timeline handoff document so whoever takes over from you for those final days gets the full context of what's happening with every vendor, whether it's small decisions like napkin folds or loading zones, or the rental delivery windows. Do make sure you provide your vendors with a new primary contact so they know who to speak to about any last-minute decisions.

The Immune Fix Protocol

I've seen many brides neglect their sleep in the lead-up to their nuptials. But if you want to protect your immune system and feel at your best on your big day, make sure you get enough sleep and stay hydrated.

This may seem like generic advice, but sleep debt accumulates fast under stress. Having one short night's sleep can impact your immune function. The CDC recommends adults get at least eight hours of sleep a night.

You'd be surprised at how low the dehydration threshold is. One to two percent of body weight in fluid loss is enough before you start losing cognitive and physical performance. Don't hydrate just when you're thirsty, since that already signals mild dehydration.

Try to watch out for what you eat as well. I recommend simple or nutrient-dense meals. I know you don't want to spend hours in the kitchen while you're planning for the most important day of your life; just make sure you eat enough whole foods, protein, and vegetables.

Your Seven-Day Wellness Checklist

Use this day-by-day wellness checklist as your planner for the final week before the wedding. I've covered wedding handoff, sleep, hydration, DIY cutoffs, and packing.

Make sure you drink about 10 cups of water a day. Sleep consistency matters more than total hours, so try to stick to a regular bedtime and waking up schedule. Aim for a 10 p.m. bedtime.

Trust Your Team

Your well-being is the most important thing on the eve of your big day, so make sure you do take care of yourself before the wedding. Pre-wedding stress leads to cortisol spikes, which affect your sleep, skin, mood, and energy. I've seen a lot of couples lose sleep over logistics that are already locked in during the days before the wedding.

Remember that your vendors- your florist, your caterers, your planners- are professionals. The timeline is set, and micromanaging every detail won't help. Just make sure you prioritize your well-being and avoid taking on extra tasks in the final days. Use that time instead for your recovery.
