Dry mouth when running: causes, symptoms & preventions

Have you ever experienced dry mouth when running? It is a pesky condition that causes your mouth to feel sticky and dry with stringy and thick saliva. Although it doesn't cause physical pain, the parched feeling makes it impossible to focus, harder to swallow, and affects your breathing rhythm. So what causes it, and more importantly, is it preventable? You'll find these answers and more below.

Why does my mouth get dry when I run?

Every runner has had their mouth dry up while running at some point. Knowing the cause is a step to recovery and we have a couple of theories. But first, we must point out that dry mouth triggers can differ from person to person and depend on factors like fitness level, hydration habits, and even breathing patterns.

Dehydration

Dehydration is the most likely cause of dry mouth when running. You lose water through sweat, but this fluid loss happens more rapidly when you run in hot weather and for long distances. When low on fluids, your body prioritizes essential functions like circulation, temperature regulation, and organ function over saliva production. As a result, your mouth dries up and becomes unusually sticky.

The way you breathe

Your breathing style also determines if you'll end up with a dry mouth at the end of your race. Many runners resort to breathing through their mouth to take in more oxygen as the run intensifies, but mouth breathing makes your moisture evaporate, and the constant airflow dries up your mouth and the throat. Instead, you should focus more on controlled nasal breathing.

Prescriptions and over-the-counter medication

Medication-induced dry mouth isn't as common. However, it is still worth looking into if your mouth dries up after every physical activity. Some medicines like antihistamines, decongestants, and certain antidepressants reduce saliva production. You must speak to your doctor or pharmacist about alternatives or ways to manage the side effects. But staying hydrated and chewing sugar-free gum would provide some relief.

Health issues

Some underlying health issues can cause dry mouth even in non-runners. Conditions like diabetes and autoimmune disorders affect the production of saliva. This can go unnoticed if you are not a physically active person. However, running can make the symptoms more pronounced because of increased breathing rate and fluid loss. If you believe a medical condition is the reason for your dry mouth, consult a healthcare provider for advice.  

Stress and adrenaline from physical exertion

When you push yourself during a run, your body releases adrenaline. This hormone is great for boosting your energy and performance, but it can also slow down your saliva production. As a result, your mouth dries up, especially when you're running hard or pushing your limits.

 The stress of intense physical exertion can leave your body in fight-or-flight mode, which prioritizes energy over things like digestion—and saliva production is part of that process. Your body becomes more focused on keeping you moving, not your mouth moist!

Environmental factors (Hot weather, cold, dry air)

Weather plays a huge role in how your body reacts while running. Hot and humid conditions can increase sweat and cause your body to lose moisture. This can lead to dehydration, which causes your mouth to dry out.

On the flip side, cold or dry air can also cause issues. When you breathe in dry, chilly air, it can sap moisture from your mouth and throat. Learning how to stop dry mouth when running involves understanding these weather extremes and making the necessary adjustments.

How can I tell if my dry mouth is a sign of dehydration?

Your dry mouth when running is usually a tell-tale sign of dehydration, especially when you feel thirsty with a parched mouth. Alongside a dry mouth, you might notice a decrease in your urine or dark-colored urine. You may also feel tired, dizzy, or lightheaded. Dry skin or a sticky feeling in your mouth also points to dehydration.

Other symptoms of dehydration-related dry mouth include a dry, cracked tongue and bad breath due to the lack of saliva.

Dehydration sets in faster when you are not replenishing the fluids you lose during your run. Once you notice these symptoms, hydrate immediately to keep your body functioning at its best.

How to prevent dry mouth when running?

A dry mouth is more than a small inconvenience; it’s your body signaling that something is off. It throws off your focus, makes swallowing difficult, and even affects your performance. Here is how to avoid dry mouth when running,

Hydrate

Staying hydrated is the most effective way of preventing dry mouth when running. We recommend drinking enough fluids before, during, and after your run. You should also increase your fluid intake when running long distances or in hot weather. Water keeps you in balance and enhances saliva production. Consider using a hydration monitor like the AbsolutSweat hydration biosensor to track your fluid levels and sweat loss so you know when to replenish. The more hydrated you are, the less likely you will experience a dry mouth.

Chewing gum or mints

Drinking water is the most ideal way of combating dry mouth when running, but chewing gum or sucking on mints works just as well. These simple remedies stimulate saliva production and moisten your mouth by activating your salivary gland.

If you don’t want extra calories, consider sugar-free mints to prevent a sugar crash. But the key is using gum or candies that keep your breath fresh as you run.

Mouth sprays

A quick spritz of a hydrating mouth spray can provide instant relief if you already have a dry mouth or prevent it altogether. Mouth sprays moisten your mouth and keep it from getting parched. They're easy to carry along on your run for rehydration as and when. Always opt for sprays with natural ingredients. They are usually long-lasting and healthier.

Breathe through your nose

When running, try to fight the temptation to breathe through your mouth. Although mouth breathing meets your body's oxygen needs, as the pace and intensity increase, it dries out your saliva. On the other hand, nasal breathing keeps your mouth moist and your throat hydrated. It also helps regulate your breathing, which is great for endurance. Honestly, nasal breathing while running takes some practice, but it is worth it for a more comfortable run.

Run in cooler environments.

You can't control the natural elements or environmental conditions, but you can control the time you run. Consider adjusting your schedule if you’ve ever struggled with a mouth dry when running. Try running early in the morning or later in the evening when temperatures are cooler. Cool air keeps moisture in your body and significantly reduces the risk of developing a dry mouth.

Preventing dry mouth when running is all about staying ahead of the problem. However, managing hydration can sometimes feel like guesswork, especially during intense runs or extreme weather conditions. That's where wearable sports tech can make a difference. Tools like the Liipoo AbsolutSweat hydration monitor take the uncertainty out of your hydration. Let's explore it now!

XUsing the Liipoo AbsolutSweat hydration monitor is a game-changer for avoiding a dry mouth. But what happens if dry mouth isn’t addressed? Beyond the discomfort, it can lead to a host of problems that impact your runs and overall health. Let's take a closer look at the negative effects of dry mouth when running.

Negative effects of dry mouth when running

Aside from the usual effects like bad breath and difficulty swallowing, dry mouth can have serious consequences like increased vulnerability to gum disease. It is why you must gain understanding to get ahead of the problem and maintain your best performance on the trail or track. Here's how dry mouth can impact your runs:

● Performance drops:A dry mouth makes swallowing difficult, creating discomfort and distraction. It reduces your focus and causes you to shift your attention away from your performance. As a result, you become less efficient during your run and may even slow down.

● Oral health risks:Saliva acts as a natural defense against bacteria. A dry mouth has little or no saliva, which eventually causes tooth decay, gum disease, and bad breath. Runners, especially those consuming sugary energy products, are at a higher risk due to the lack of saliva to neutralize acids.

● Increased dehydration: A dry mouth is a sign your body is dehydrated. This means your muscles and organs may not have adequate fluids, increasing fatigue and risking cramps or overheating. Dehydration also affects endurance and makes long runs more challenging.

● Difficulty breathing:Mouth breathing during intense runs dries out oral tissues further. This worsens dry mouth, causes laborious breathing, reduces oxygen intake, and impacts performance.

● Fatigue and discomfort: The combination of dehydration, difficulty swallowing, and lack of lubrication in the mouth makes running less enjoyable. It is harder to be motivated when you have persistent discomfort.

If you are a regular or professional marathon runner, you must take dry mouth issues seriously because it directly impacts your performance and health. Understanding how to prevent dry mouth when running is a start.
