Why Does Your Nose Run When You Walk?
If you've ever noticed that your nose starts dripping like a leaky faucet as soon as you start walking, you're not alone. This phenomenon is incredibly common and has a logical physiological explanation behind it.
The medical term for a runny nose is rhinorrhea. It occurs when your nasal passages become filled with excess mucus secretion. This overproduction of mucus then starts to uncontrollably drain out of your nose.
There are many potential causes of rhinorrhea, ranging from harmless to more serious underlying conditions. When it happens specifically during walking, there are two main mechanisms at play:
1. Aerodynamic Factors
As you start to walk, your pace and breathing rate increases. The rhythm of your footfalls combined with your breathing leads to a cyclic pressure change within your nasal cavity.
This cyclic pressure essentially pumps out the mucus that has accumulated inside your sinuses and nasal passageways. The faster you walk, the more pumping occurs, leading to more dripping.
There is also an aerodynamic effect as air rushes past your nasal tissues at a higher velocity during walking or exercise. This helps thin out the mucus and propel it forward.
2. Physiological Stimulation
When you exercise, your sympathetic nervous system kicks in, causing a fight or flight response. This leads to physiological changes like increased heart rate, blood pressure, and breathing rate.
As part of this response, your nasal mucosa releases more mucus. This helps moisten and protect the nasal tissues as you breathe harder. The excess mucus can then drain out, causing a runny nose.
This stimulation of mucus production occurs even with mild aerobic activity like walking. That's why your nose starts running as soon as you start moving faster.
Why Do Noses Run More Easily for Some People?
While a runny nose during walking is normal for many people, some individuals are more prone to it than others. Here are some factors that can lead to increased rhinorrhea with mild exertion:
1. Hyperresponsive Nasal Membranes
Some people simply have more sensitive nasal tissues that overreact to stimuli. Mild irritation from dust or airflow causes excess mucus production. This can lead to a chronically runny nose.
2. Allergic Rhinitis
Allergic rhinitis, or hay fever, causes chronic nasal inflammation. This makes the nasal membranes more likely to produce excess mucus in response to triggers like exercise. Seasonal allergies often worsen the drippy nose effect of walking.
3. Nonallergic Rhinitis
Nonallergic rhinitis involves chronic nasal congestion and rhinorrhea without an allergic source. Causes include irritants like pollution, weather changes, spicy foods, and emotional stress. This can exacerbate running nose with walking.
4. Vasomotor Rhinitis
Vasomotor rhinitis is triggered by the autonomic nervous system causing nasal blood vessel dilation and mucus gland stimulation. Physical activity can bring on symptoms like profuse nasal drainage.
5. Gustatory Rhinitis
Gustatory rhinitis is a reflex that causes rhinorrhea after eating, particularly spicy or hot foods. The nasal nerves are sensitive and overreact to chewing, leading to increased mucus production.
Is a Runny Nose While Walking Anything to Worry About?
For most people, a runny nose that starts up when walking is not considered a serious medical condition. As long as it goes away after the activity ends, it is simply an annoyance.
However, frequent or severe bouts of exercise-induced rhinorrhea could potentially indicate an underlying chronic nasal or sinus condition. It's worth discussing with your doctor if it becomes a bothersome issue.
See your physician promptly if your runny nose is accompanied by any of the following:
- - Thick, yellow/green mucus
- - Facial pain or pressure
- - Reduced sense of smell
- - Fever, headache, fatigue
- - Persistent post-nasal drip cough
These symptoms may be a sign of chronic rhinosinusitis, nasal polyps, or sinus infection requiring treatment.
Tips to Prevent a Runny Nose While Walking
While you can't always stop a running nose triggered by exercise, you can take steps to minimize it:
Use a Saline Nasal Rinse
Saline nasal irrigation can help flush out excess mucus before it starts running. Use a Neti pot or nasal spray to rinse your nasal passages prior to going for a walk.
Take an Antihistamine
For seasonal allergy sufferers, an oral antihistamine like Zyrtec or Claritin can help reduce mucus production and associated dripping. Take it about an hour before going outside.
Try a Decongestant Spray
Nasal decongestant sprays like Afrin constrict blood vessels to open nasal passages. Use sparingly to avoid rebound congestion. This lessens airflow irritation of the nasal membranes.
Wear a Cold Weather Mask
A cold weather mask that covers your nose can help humidify and warm the air, preventing nasal irritation. Bonus points if it catches any drips!
Walk at a Slower Pace
Try moderate walking instead of a jog/run which intensely stimulates mucus production. Gradually build up your pace as your body adjusts to the aerobic stimulus.
Avoid Triggers
On high pollen count days or when you're fighting a cold, stick to indoor exercise. This prevents exacerbating nasal symptoms leading to a drippy mess.
When to See a Doctor for Runny Nose While Walking
Schedule an appointment with your physician if you have persistent rhinorrhea that:
- - Lasts more than 10-14 days
- - Worsens despite self-care remedies
- - Is accompanied by other nasal/respiratory symptoms
- - Significantly impacts your quality of life
Your doctor can assess for potential causes like chronic rhinitis conditions, nasal polyps, deviated septum, sinusitis, allergies, and other disorders.
They may recommend medication or therapies like nasal steroid spray, saline irrigation, surgery, allergy shots, or lifestyle modifications to help manage bothersome runny nose.
The Bottom Line
It can be annoying and messy when your nose starts uncontrollably running every time you start moving. But for most people, mild exercise-induced rhinorrhea is harmless and temporary.
Use self care tips to minimize dripping as much as possible. See a doctor if it becomes chronic and disruptive to your daily activities and quality of life.
With the right prevention and treatment, you can still enjoy walks and light exercise without having to constantly wipe your nose!
FAQs
Why does my nose run every time I start walking or exercising?
When you walk or exercise, your breathing rate increases, which pumps air through your nasal cavity and essentially pumps out mucus. The increased airflow also thins out the mucus. Additionally, your sympathetic nervous system responds by producing more mucus to moisten the nasal tissues as you breathe harder.
Is a runny nose while walking normal?
Yes, for most people having a runny or dripping nose when you start walking faster or exercising is very normal. It's simply a response to the increased airflow and stimulation of mucus production.
How can I prevent my nose from running when I walk?
Tips to minimize a runny nose during walking include using a saline nasal rinse beforehand, taking an antihistamine if allergies are a factor, using a decongestant nasal spray, wearing a cold weather mask, walking at a slower pace, and avoiding triggers like cold weather.
When should I worry about a runny nose while exercising?
See your doctor if the runny nose lasts longer than 10-14 days, doesn't improve with self-care remedies, is accompanied by thick or colored mucus, facial pain/pressure, reduced smell, fever, or cough. This may indicate an underlying chronic nasal condition requiring treatment.
What causes make some people more prone to a runny nose when walking?
Factors that can increase susceptibility to a dripping nose during walking include nasal membranes that overproduce mucus, chronic conditions like allergic rhinitis and vasomotor rhinitis, nonallergic rhinitis, and gustatory rhinitis triggered by eating spicy foods.
