Here’s Why Your Ears Pop When Climbing a Mountain


When you climb mountains, your ears would often pop, but there is no reason to panic when this happens because the cause is quite natural.

Why do your ears pop when mountain climbing? It has to do with the change in air pressure, which can have a huge impact on your ears’ inner mechanisms. Basically, your ears rely on a sensitive system of nerves and fluids to function, which reacts to air pressure. As you climb higher, the air pressure changes, thus cause the feeling of popping.

On that note, ear-popping can be quite a useful sign of how high you have already climbed and can actually save your life if you know enough about it.

Bodily Changes When Mountain Climbing

Now, in order to tackle the matter of the ear-popping that occurs when you are climbing a mountain or when there is a change in altitude, you need to understand what happens to your body in that time. Simply put, there are several factors that can actually impact how your body reacts as you climb a mountain, including:

·         Air pressure

·         Weather

·         Temperature

·         Fitness level

·         Health condition

·         Exhaustion

·         Stress

Depending on the circumstances, it would not be strange at all for all of those factors to come together at once and when they do, you will have more than just ear-popping to worry about. To that end, here are some of the physical changes that you can expect when you climb mountains:

Physical EffectsDescription
Oxygen DeprivationAir is thinner in higher altitudes, leading to reduced oxygen intake
Lung SwellingThe constriction of blood vessels can cause the lungs to swell, making breathing difficult
Increased Heart RateOxygen deprivation means less oxygen circulating, forcing the heart to beat faster
Temporary BlindnessHigher altitudes can reduce to spasms, reducing blood supply to the eyes
NauseaDigestion slows at high altitudes, leading to nausea and vomiting with uncontrolled food intake
Pressure EqualizationThe ear pops as the pressure drops, causing either blockage or clearing

Now, it is worth noting that these changes would depend entirely on how high up you have already climbed. Naturally, taller mountains would lead to more severe symptoms, but this shouldn’t be an issue with shorter peaks.

In the case of the pressure equalization, though, this is quite the important detail to note due to how it can indicate how high you have already climbed. Everything will then stem from that particular sign, which will be an essential point to note.

The changes noted in the table above are the reasons why inexperienced climbers are advised never to attempt a climb of the more dangerous mountains in the world. Among the leading causes for deaths for those who try to climb Mt. Everest, for example, can be directly tied to the symptoms discussed above.

As such, you must never take these kinds of signs for granted if only because they can be the difference between life and death. Climbing mountains is a worthy endeavor that can leave you feeling accomplished and euphoric. At the same time, the activity also comes with the potential for severe consequences if you are not mindful of the dangers that come with it.

Why Your Ears Pop When Mounting Climbing

As already mentioned, the reason why your ears pop when you reach higher altitudes is due to pressure equalization. This is basically where the air pressure has changed compared to what it was previously due to how thick or thin the air has become. When this happens, your ears’ inner mechanism responds in kind because of how your ears rely so much on equilibrium.

This is basically what happens when you are in an airplane that is ascending to the skies or when you are going deeper into the earth’s crust. Your ears will compensate for the changes to both protect its more sensitive parts while also making sure that you can maintain your balance. As such, if your ears are popping when you are climbing a mountain, this is just a means of recalibrating.

Normally, you would not need to pay attention to the phenomena if it occurs in an everyday setting. However, since you are climbing a mountain, it is a sign that you will need to watch out for. It is basically one of the most reliable ways of determining just how high up you have already climbed and for you to take the appropriate precautions when it happens.

Is Ear Popping a Bad Sign?

When your ears pop, this is not a bad sign in and of itself. Rather, it is your body’s way of telling you that there has been a change in your environment. When mountain climbing, this means that you have climbed high enough that the air pressure has changed. When that happens, you will then have a few things that you will need to do.

First, you will need to check your GPS equipment if you have it or just any equipment that you may possess, which can confirm your altitude and location. From there, you will want to make a few changes in terms of the speed of your pace, the way you breathe, and even in the way you move.

Your eating habits might need to change, as well, with the kinds of food that you will want to consume is easy to digest and light while still giving you energy. Whatever you do, you must not consume heavy food items as you are climbing because this can lead to issues with your digestion. You remember the part about nausea and vomiting, right?

Expending excess energy will be bad for you, as well, since your body will be going into calorie conservation mode and oxygen will be in reduced supply. As such, don’t be surprised if you start feeling sluggish when you reach a certain altitude. To that end, you must move more deliberately and with fewer wasted movements.

Can Your Eardrums Burst When Climbing?

Unless you have a health condition where there is a blockage in your veins and arteries located in your ears, there should be no reason for your eardrums to burst while climbing. If it does, you must suspend your climb immediately and seek medical attention.

How to Unblock Your Ears?

If you find that your ears are blocked as you climb, among the methods for clearing them up is to swallow, to fake a yawn, to chew gum, and to take nasal decongestants. You could also try to hold your breath and blow air through your ears by closing your mouth and pinching your nose.

What Is Altitude Sickness?

Altitude sickness is basically a series of radical changes in your body’s functions due to the environmental shifts that occur as you ascend. All of these have already been discussed in the earlier sections, which should impress upon you just how serious of a condition this is. If you are not careful, it could lead to irreparable damage to your body.

Generally speaking, you will be feeling an acute sense of vertigo and nausea when you are suffering from altitude sickness. You will also lose motor control and your whole body will basically go haywire. When left unchecked, it would be no exaggeration to say that you are risking death.

However, before that happens, there can also be a bunch of other unfortunate occurrences that can happen while you are suffering from altitude sickness. Among them are hallucinations, delusions, and paranoia. If you are in a group, for example, it would not be weird for you to start thinking that they are out to get you.

This becomes particularly acute when you are in a high-stress situation like when you are lost or when there are wild animals around. Suffice it to say, the threat of you doing something to your companions or them doing something to you is quite real.

How to Prevent Altitude Sickness?

Preventing altitude sickness is basically all about trying to reduce the load that your body will be taking as you climb. The best precaution you can take is to simply take smaller trips in smaller mountains before tackling the big ones. Gradually increasing the difficulty of the climb will allow you to acclimate and thus reduce the shock to your body.

Now, assuming that you are already on your way to climbing really tall mountains. The best way would be to wait for your ears to pop. From there, you will need to change your habits, as detailed above. Your breathing must become more measured, you must become more vigilant, and your movements must become more economical.

More than that, you need to take a break every now and then to allow your body to acclimate. At the end of the day, altitude sickness is basically just a sign that your body is not used to such an environment. After a few minutes of rest, you should be good enough to proceed without risking the more severe consequences.
