Cold Showers to Avoid the Flu? New Study Says Maybe
Written by Zach Miller on November 3, 2026
Let’s be honest: the hot shower is the only 10 minutes of the day nobody is asking you for a snack. It’s your sanctuary. Your spa. The one place you can hide from the permission slip you forgot to sign.
So brace yourself, because a new study is asking a very rude question: Would you trade that steamy shower for an ICE-COLD one if it meant you’d get sick less?
The Study That’s Coming for Your Hot Water
Researchers in Switzerland followed adults for 12 weeks to see whether shower temperature had anything to do with how often they got sick.
The setup was simple:
- The brave group: Turned the water to the coldest setting every day, for anywhere from 30 seconds to several minutes
- The middle group: Mixed it up with some cold and some warm
- The sane group (no judgment): Stuck with warm showers the whole time
And honestly? Nobody tested the scalding, lobster-red showers some of us take. That data would’ve been very personal.
So… Did Freezing Actually Work?
Here’s the headline that’s going to make you side-eye your shower knob. The all-cold-shower crew reported 26% fewer days feeling sick and took 31% fewer sick days from work.
With cold and flu season officially here and the school germ factory running at full speed, that’s tempting. Fewer sick days for you means more sick days saved for when the kids inevitably bring something home.
Okay, Here’s the Fine Print
Before you go full polar bear, there are some big caveats worth knowing:
- It’s a link, not proof. People chose their own shower habits instead of being randomly assigned, so the cold-shower folks might have just been healthier to begin with.
- The crowd was young. The average participant was 26 years old, and about two-thirds were women. So… not exactly a room full of exhausted parents running on reheated coffee.
- The difference was small. That 26% drop worked out to roughly one day a month or less.
- It was all self-reported. No doctor visits or medical follow-ups confirmed anyone was actually sick.
- It’s not for everyone. People with severe heart disease or severe asthma were excluded, since cold water can make those conditions worse. If you’ve got health concerns, check with your doctor first.

Want to Try It Without the Shock?
If you’re curious but not ready to scream at 6 a.m., you don’t have to go all in. Some easy ways to dip a toe in:
- End with a blast: Take your normal warm shower, then switch to cold for the last 30 seconds
- Ease in: Turn it down a little colder each week
- Breathe through it: Slow, steady breaths make the first few seconds way less dramatic
- Keep the basics: Cold water isn’t a magic shield, so handwashing, sleep, and your flu shot still do the heavy lifting
Worst case? You’ll be very awake for the school drop-off line.
