Salt Therapy for Runners Breathing Cold Winter Air

You know the run. It's a January Saturday, the bank sign in Anoka reads 8 degrees, and you head out for your long run along the Rum River anyway. By mile three, every breath feels like it's scraping the back of your throat. By mile six, there's a tightness in your chest that lingers through your post-run coffee.

If you log winter miles in Anoka, Andover, Ham Lake, or East Bethel, that feeling comes with the territory from about November to March. So it's no surprise more local runners are asking about halotherapy for runners: quiet sessions in a warm, dry salt room, a counterweight to all that frozen air. Here's what cold air does to your airways, what actually happens in a salt room, what the research on athletes shows, and a handful of habits that make winter running easier to live with.

What Cold, Dry Air Does on a Winter Run

Why your throat and chest feel it

Your nose and airways are built to warm and humidify every breath before it reaches your lungs. On a mild day in May, no problem. On a Minnesota winter morning, that system is working overtime. According to Harvard Health, cold, dry air can irritate the airways and lungs even in healthy people. It can cause the upper airways to narrow and disrupt the thin moisture layer that lines the lower airways.

Running makes it worse. Once you're breathing hard, most of that air comes in through your mouth and skips the nose's built-in warming. A review of cold-weather sport research explains that breathing large volumes of cold, dry air pulls water from the airway lining, which can trigger airway narrowing. That response tends to get stronger as temperatures fall from 32°F toward -4°F — a range North Metro runners know well.

It usually passes quickly

Now the good news. For most people, those post-run dips in breathing function don't stick around — the same review notes that respiratory function typically returns to pre-exercise levels in under 30 minutes.

Airway narrowing is also more common than you'd guess among athletes who train in the cold. In one study of the 1998 U.S. Winter Olympic team, about half of cross-country skiers showed it. Why does that matter to a weekend runner in Ham Lake? Because a cough, wheeze, or chest tightness that doesn't settle after your runs is a conversation for your doctor. Not something to tough out.

What Happens in a Salt Room Session

Active vs. passive salt rooms

Halotherapy, sometimes called dry salt therapy, means spending time in a room where you breathe air carrying tiny salt particles. Cleveland Clinic describes two styles. "Active" rooms use a machine that breaks salt apart and circulates the particles, while "passive" rooms are simply lined with large amounts of salt for a calm, spa-like atmosphere.

In active rooms, a device called a halogenerator grinds salt into micro-particles smaller than five microns. Research settings keep the room at about 68–75°F with 40–60% humidity. After a single-digit morning, that alone feels pretty great.

What it may offer

The idea you'll hear most often is that breathing in salt particles appears to thin mucus, which may make phlegm easier to clear. Cleveland Clinic adds a simpler point: the calm setting is relaxing all by itself. You sit. You breathe normally. Your body settles.

At our salt halotherapy room at 5D Wellness in East Bethel, a session looks exactly like that: comfortable seating, soft lighting, and 45 minutes where nobody needs anything from you. Local clients use it in other seasons too — we've written about halotherapy on summer smoke days for the other end of the Minnesota calendar.

What the Research on Athletes Shows

The 12-week preseason trial

The study most relevant to runners is a recent one. During the 2022–2023 preseason, researchers ran a randomized controlled trial with 28 elite female football players split into two groups. Both did identical training, but one group also spent 45 minutes in a halotherapy room three times a week for 12 weeks.

Compared with training alone, the halotherapy group saw larger gains in breathing-muscle strength, lung function, and aerobic capacity:

• Maximal inspiratory pressure (how strongly you can breathe in): up 33% vs. about 10%
• VO2max (aerobic capacity): up 9% vs. about 3.6%
• FEV1 (how much air you can push out in one second): up 15.9% vs. 10%
• Intermittent running test performance: up 24% vs. 15.5%

Read it with honest caveats

Interesting numbers. Still, it's one small study. Every player came from a single club, there was no "sham" salt room to rule out a placebo effect, and the short preseason window meant nobody checked whether the gains lasted. The authors say more research is needed, and Cleveland Clinic makes a similar point about halotherapy in general — there isn't yet enough rigorous clinical research to confirm many of the claims. Results vary from person to person. We'd call a salt room a supportive recovery habit, not a shortcut to a faster 10K.

Fitting Salt Sessions Into a Winter Running Week

No need to overhaul your training plan. Most runners start with one session a week through the coldest stretch and see how it feels. A simple winter week for a Blaine or Coon Rapids runner might look like this:

• Tuesday: easy treadmill or indoor run, followed by a salt room session to wind down.
• Saturday: long outdoor run on the Rum River or Bunker Hills trails.
• Sunday: rest day with a second salt session if it fits your schedule.

Halotherapy also plays well with other recovery tools. Plenty of local runners pair it with the cold plunge or sauna — our guide to cold plunge for marathon recovery and our infrared sauna guide for North Metro runners cover how those fit together.

For your first visit, wear comfortable clothes, silence your phone, and simply breathe normally. Some people notice a slight cough or a salty taste afterward; that's common and usually brief.

Cold-Air Breathing Habits for North Metro Runners

A salt room is only one piece. On frozen mornings, these everyday habits do most of the work:

• Cover your nose and mouth. A scarf or buff helps warm and moisten the air before it reaches your lungs, as Harvard Health recommends.
• Warm up longer. The cold-sport review suggests 10 to 15 minutes of moderate warm-up. Cleveland Clinic sports medicine physician Caitlin Lewis, MD, recommends doing dynamic stretches indoors before you step out.
• Dress for 15–20 degrees warmer. Dr. Lewis's rule of thumb keeps you from overheating and sweating through your layers. Start with a moisture-wicking base, not cotton.
• Drink water anyway. Mayo Clinic notes you lose fluid through sweating and breathing in winter, so drink before, during, and after your workout, even if you're not thirsty.
• Know when to go inside. When the temperature dips below 0°F or the wind chill turns extreme, Mayo Clinic suggests an indoor workout instead. The Anoka County trails will still be there next weekend.

Frequently Asked Questions

Is halotherapy good for runners in winter?

Many runners use salt room sessions as a calm, comfortable break from dry winter air. One small 2022–2023 trial in elite athletes saw larger gains in breathing-muscle strength and aerobic capacity when halotherapy was added to training, but the research is early and results vary by individual. Think of it as a supportive part of a recovery routine, not a performance shortcut.

Should I do a salt session before or after a cold run?

Either works. After a run, a salt room is a relaxing, temperate place to let your breathing settle. Before a run, some people like it as part of an unhurried start to the day. Either way, still do a proper 10–15 minute warm-up before hard outdoor efforts.

How often should I book halotherapy?

Research protocols have used 45-minute sessions two to three times a week, but there's no set standard. Many people start with one session a week through the coldest months and adjust from there.

Who should check with a doctor before trying a salt room?

Anyone who is pregnant, has asthma or another lung or heart condition, or has any ongoing health concern should talk with a healthcare provider first. A salt room is a wellness experience, not medical care, and some people notice a bit more coughing afterward.
