Nasal obstruction and acid reflux are the two most common causes of sore throats caused by running. When the airflow through the nose is poor, it becomes more difficult to oxygenate. We naturally open our mouths when we are out of shape to breathe more easily.
The four contributing causes of a sore throat after running are:
1. Humidity
2. Inhaling with Your Mouth Open Acid Reflux
3. Acid Reflux
4. The Temperature Outside
Why Does My Throat Hurt After Running?
Running is one of the most common and effective forms of exercising. When you run, you activate most of your muscles and cardiovascular organs.
In fact, it is the best form of cardiovascular exercise as it makes you breathe faster and more deeply.
Unfortunately, there are several interesting yet disturbing conditions that you may experience as you make your run.
One of the most common ones is having a sore throat while running or after the run. This begs the question-especially in new runners' minds-, why does my throat hurt when I run?
Brief Explanation of the Most Common Cause of these Throat Pains
It is important to note that the overall impact of any running exercise in your body depends on a number of factors including your current health condition, your breathing methods, and the environment in which you are performing the exercise.
When you run, there is inhalation and exhalation of air, a process that increases as you increase your speed of running.

The air passing through the throat cavity towards the lungs may result in irritation and soreness of the throat.
We can also experience this kind of sore throat from any other sort of vigorous activity besides running. Some experts believe that this problem is caused by nasal congestion or in the case of acidic reflux conditions in the body of a person.
Therefore, depending on our technique and nature of breathing during running, many of us runners will experience a hurting pain during or after the run.
While in some the pain may be acute and intensified, in others it is mild and manageable.
Running is of course a great habit that can be accompanied by amazing health benefits, but if it comes with any kind of pain, the whole activity and its benefits are nullified.
A hurting throat can also be enhanced by other causes, which include:
1. Humidity

If you run in a dry climate, regardless of whether the air is cold or hot, you are likely to develop a a scratchy throat during running.
If the air is too dry, it will dry out the lining of your throat as you breathe heavily in the course of your running.
The ACAII shares that environmental allergens such as dust and pollen may also give you a drying and irritating feeling on your throat.
For those who prefer running on an indoor treadmill, using a humidifier to increase the air humidity will help prevent you from experiencing this feeling.
2. Inhaling with Your Mouth Open

3. Acid Reflux
Running right after taking a meal or when your food has not been fully digested may cause the acids in the stomach to jump up right back into the mouth cavity due to the vigorous activity.

This will result in the irritation of your throat and hoarseness of voice as well.
The good news is that you can grab some over the counter acid reflux pills or tablets to help with this.

- Multi-Symptom Relief: This heartburn medicine treats the four signs of heartburn: burning in the chest, acid indigestion, sour stomach and upset stomach associated with these symptoms
4. The Temperature of the Air
Air temperature is a very common cause of pains and irritations in our throats during running.
When air at lower temperature travels through our nasal or throat cavity as we breathe fast and deep, it is sure to cause some nasty side effects.
A sore and painful throat is one such result.

Pharyngitis, which is a result of inflammation of the throat as well as pains in the back, is also likely to occur to some people. This can also lead to strep throat.
To void this kind of problem, always make sure that you cover your mouth and face while running to prevent the dangerous cold air from entering your breathing cavity. View these balaclavas that keep your face and mouth covered.
