Getting out of bed for a morning run becomes a lot harder for some of us when the weather turns cold. Making it part of your routine takes a bit of discipline at first. After a while, you get used to it. But then, a few minutes into a cold-weather run, your throat can start to burn. You might feel some mild discomfort in your chest, too. And the first thought is usually: “Is this cold air bad for my lungs?” I’ve given up on plenty of runs because of that worry. You’ve already talked yourself out of bed, and now you’re trying to decide whether to keep running.

You might be wondering, “Is running in cold weather actually harmful?” Running in the cold doesn’t automatically mean you’re damaging your lungs. But breathing cold, dry air during hard exercise can irritate the airways and cause them to narrow in some people. How sensitive you are varies from person to person.^[1]^[2] So neither putting your shoes away because “you shouldn’t run in the cold” nor pushing through because “it’ll be fine” is a great answer. In this article, I’ll try to explain why our throats burn, what we can adjust, and which symptoms deserve proper attention.

Why do your throat and chest burn when you run in the cold?

One of your airways’ jobs is to warm and humidify the air you breathe in. When we start running, we breathe more air. As cold air goes through that process, the airway surface loses water and heat. During harder exercise, that increased drying can contribute to irritation and airway narrowing in susceptible people.^[1] Breathing in and out feels simple enough from our side, but there’s some preparation going on inside. Then we decide to pick up the pace on the first hill and give the system a bit more work.

A study published in 2022 looked at healthy participants exercising hard at −15°C. Throat and chest irritation were more pronounced during exercise than when resting in the same cold conditions. Markers of stress in the cells lining the airways also increased. However, these findings don’t show that a single run causes permanent lung damage.^[1]

So a burning sensation doesn’t automatically mean something has been damaged. But let’s not blame every bit of chest discomfort on the weather, either. New or recurring chest symptoms need medical assessment.^[5]

The runner next to me looks perfectly comfortable. Why am I struggling?

It’s easy to judge your own running by looking at the person beside you. They’re chatting away while you’re saving your answer for the next flat stretch.

But being on the same path doesn’t mean you’re working equally hard. One of you might be taking it easy while the other is running at quite a high effort for their current fitness. That’s why the focus on water loss from the airway surface in cold-weather exercise research matters. We need to look at the workout as well as the temperature.^[1]

Especially when the weather first turns cold, try not to increase everything at once. More distance, a faster pace, a new route while we’re at it… We can end up asking quite a lot of one morning run. A short loop near home can be more practical. If things are going well, you can carry on as planned. If you want to head back, home is still nearby. Realising you should have kept it short is less useful when you’re five kilometres from your front door.

What is exercise-induced bronchoconstriction?

The name is a mouthful, but here’s what it means: exercise can cause the airways to narrow temporarily. This is called exercise-induced bronchoconstriction, or EIB. It can affect people with asthma, but it can also occur in people who haven’t been diagnosed with asthma. Symptoms include coughing, wheezing, chest tightness and shortness of breath. They can become more noticeable after the run, too. However, having one of these symptoms isn’t enough to diagnose EIB. When needed, clinicians measure lung function before and after exercise.^[2]

If these symptoms keep coming back, see a respiratory specialist. Being able to describe what happened in a little detail can help. When did it start? Had you picked up the pace? What happened when you stopped, and how long did it last? Does the same thing happen on a treadmill? Your running watch already logs the distance. If you jot down these details as well, there’s less chance of arriving at the appointment with, “Something happened the other day, but I can’t quite remember.”

If you have asthma

Agree on a cold-weather running and medication plan with your doctor. Discuss what to do if symptoms start, and don’t change your medication use yourself.^[2] Don’t try a medication just because a running friend recommends it. We don’t even all get on with the same running shoes; let’s not assume one medication plan fits everyone.

Should we breathe through the nose or the mouth?

Your nose helps warm and humidify the air you breathe. You can try nasal breathing at an easy pace, but you don’t need to force yourself to breathe only through your nose.^[2]

Sometimes the running checklist gets a little long: relax your shoulders, watch your stride, keep your heart rate down, breathe through your nose. Before long, you’re running while trying to supervise every part of your body.

Breathing through your mouth doesn’t mean you’re doing the run wrong. If you’re struggling, try taking it a little easier that day. It’s nice to see your usual pace on the watch, but you don’t have to hit the same number every morning.

Does a buff or neck gaiter help?

A neck gaiter covering your mouth and nose may help warm and humidify the air you breathe. But a regular buff isn’t the same as the specialised heat and moisture exchange masks used in research. We can’t assume they deliver the same results.^[2]

When choosing a gaiter, don’t just look at how thick it is. It also needs to stay in place and let you breathe comfortably. If you’re pulling it back over your nose every hundred metres, you’ve added another task to the run.

Try a new one on a short, easy outing first. Discovering three kilometres into a long run that you and the fabric don’t get along isn’t much fun. And wearing a gaiter doesn’t make every condition suitable for running. If you’re having symptoms, don’t just add another layer and try to push through.

Is it better to warm up indoors before heading out?

When getting ready in the morning, it’s easy to feel that putting on our running shoes means we’re ready to run. Especially if we’re running late, the warm-up can quietly disappear from the schedule. Instead, you can do part of your preparation indoors. A few minutes of marching in place, some controlled dynamic movements, then walking and easy jogging outside… You don’t have to reach your target pace on the first street.

This is a general preparation suggestion. We can’t say, “I did a few movements at home, so bronchoconstriction won’t happen now.” The EIB guideline supports interval or variable-intensity warm-up routines in particular, but that isn’t a guarantee of protection.^[2] If you’re wondering which movements to start with, take a look at the dynamic movements in our race-morning warm-up guide.

How cold is too cold to run?

This is where you want a definite number. Check the weather app, see that it’s below the limit, put the coffee on. That would make the decision easier. But there isn’t one temperature limit that applies to everyone. A study involving 17 physically active women compared running trials at five temperatures between 0 and −20°C. Some respiratory symptoms became more pronounced in colder conditions, and responses varied between participants. We can’t turn those results into a firm cut-off for every runner.^[3]

Still, you can use the following cautious approach when planning:

Conditions	What could you choose to do?
Above freezing, with comfortable breathing	Start easy and adjust your effort to the day.
Below freezing, and you’re not used to these conditions	Choose a short, easy route close to home.
Around −15°C or colder	Consider moving hard workouts indoors in particular.
Wheezing, chest tightness or significant breathlessness at any temperature	Stop the workout and seek medical assessment according to your symptoms.

The −15°C figure in the table isn’t a medical cut-off. It’s a cautious planning suggestion informed by the research findings. Warmer conditions don’t guarantee a symptom-free run for everyone, either.^[1]^[3]

We’ve checked the temperature. What about the path?

Before heading out, think about the surface, too. It might be cold but dry underfoot. Or the temperature might not look especially low while your running route has icy patches.

A route you know well can make things easier, especially on dark mornings. Is rain or snow expected? What’s the wind doing? Can you get home early if you need to? Check those things while you’re getting your kit ready.

What to wear is another question altogether. If you’re standing in front of the wardrobe undecided, our guide to what to wear when running in cold weather has suggestions for different temperatures.

Will moving the workout indoors mess up the plan?

Say you’ve got fast intervals on the schedule. You check the forecast in the morning, and it’s much colder than you expected. Taking that session to the treadmill or moving it to another day is an option.

You can swap days in your weekly plan when needed. Put the easy run on a more suitable day, do the faster work indoors, and so on. Following a plan doesn’t mean you have to complete the same line on the schedule regardless of the weather.

On the treadmill, start by deciding what you want from that session. An easy run? A specific workout? Then adjust the duration and effort accordingly. Our treadmill running guide has some starting suggestions. The scenery doesn’t change much, but at least you won’t discover a headwind on the way back.

Can running in cold weather make you sick?

Most of us have heard some version of, “You got sweaty and stayed out in the cold. You’re bound to get sick.” But infections such as colds and flu are caused by viruses. Cold air alone doesn’t cause those infections. The CDC describes the common cold as a viral upper respiratory tract infection. Flu is a different viral infection.^[4]

So a burning throat during your run doesn’t mean you’ve just picked up an infection. Irritation and infection aren’t the same thing. That doesn’t mean there’s no risk of getting ill in winter, of course. Respiratory viruses circulate throughout the year, and some, including influenza and RSV, are more common during the winter months.^[4]

If you develop a fever, feel generally unwell or have ongoing respiratory symptoms after a run, don’t explain everything away with, “It was a bit cold this morning.”

When should we take chest burning seriously?

Let’s put the jokes aside here. Describing chest discomfort as “burning” doesn’t mean it’s harmless. Some heart-related problems can also feel like burning or indigestion.^[5]

Stop running and seek emergency help if you have:

Sudden chest pain, pressure or tightness that doesn’t go away.
Pain spreading to your arm, jaw, neck or back.
Chest discomfort along with shortness of breath, sweating, nausea or dizziness.^[5]

In Türkiye, the emergency number is 112.^[6] Even without emergency symptoms, get medical advice about chest pain that comes and goes or keeps returning. The fact that it settles with rest doesn’t mean you can work out the cause yourself.^[5]

Before you head out tomorrow morning

Know your route and make sure you can head home early if needed. Try not to test a new gaiter, increase your distance and pick up the pace all on the same day. Keeping the first outing short makes it easier to see what’s working and what isn’t. When you get home, think about how the run went as well as the distance. Was the gaiter comfortable? Were you wearing too much? Did you have any symptoms? Remembering those details can be more useful when getting ready the next morning than a few seconds on your watch.

Sometimes building the habit does mean talking ourselves out of the door. That’s true. But once we’re outside, we can still make decisions based on the day’s conditions. A shorter run, an indoor session or postponing the workout are all options.
