If you’re healthy but still yawning often, there are certain lifestyle changes you can adapt to help you. This includes exercising regularly, trying to reduce stress, and of course sticking to a regular sleep cycle where you can achieve 8 hours of sleep every night.
What to Know About Yawning
You may not notice how often you yawn, or you may wonder why you can’t stop yawning. Yawning is a common reflex where you open your jaw wide, take in a deep breath, and then quickly exhale. Typically you’ll feel more relaxed right after you yawn. There’s not an exact reason why people yawn, but there are many theories.
What Is Yawning?
Yawning has long been connected with feeling tired or bored. But, there are new studies that suggest this might not be true. Since there’s no known cause for yawning, these new studies offer theories for why you yawn.
Newer studies suggest that yawning might do more than get oxygen to your brain.
When you yawn, researchers think you may be communicating how you’re feeling: whether you’re tired, bored, or under mild stress. Some researchers think that yawning is an empathetic and social skill where we show that we connect with others.
Reasons for Yawning
There’s not any specific reason why you yawn. Regular yawning is a reflex in your body that just happens involuntarily, meaning that you do it without thinking about it. However, there are many things that researchers agree cause yawning.
Change in elevation. If you’re in an airplane or driving in different elevations, you might yawn on purpose or as an automatic response from your body. This is your body equalizing the pressure in your ear.
Empathy. Another cause of yawning is social empathy. If you see someone yawn or even read about yawning, you might have an urge to yawn. Psychologists say that you’re more likely to yawn when you see someone else do it if you’re more empathetic. The closer you are to someone, the more likely you’ll be to yawn if they do.
Feeling bored or tired. Studies have shown that yawning isn’t a sign of being tired or feeling bored. Rather, it’s a reflex from your brain that makes you wake up or feel more alert. Yawning is your body’s way of trying to wake you up.
Cool your brain. Another unproven theory is that yawning is your body’s way of cooling your warm brain. The theory is that you will yawn more in situations where you’re overheated. Deep breaths and open mouths have been shown to cool the brain a little. However, there’s not enough evidence for this theory.
Stretches your lungs and lung tissue. When you yawn, it’s sometimes followed by a larger stretch. By yawning, your body could be flexing your muscles and stretching your joints. You might also have an increased heart rate. By stretching your lungs and improving your heart, you’ll also feel more awake.
Now that you know the possible reasons for yawning, you might pay more attention to when you yawn. Typically people don’t notice their yawning unless it’s happening more than usual.
Is Excessive Yawning a Concern?
When you start to yawn a lot and you can’t stop, you might begin to worry. Excessive yawning may be caused by an underlying condition. These conditions include:
- Sleep deprivation, or when you continually don’t get enough sleep
- Insomnia, a condition where you have trouble falling asleep or staying asleep
- Sleep apnea, a condition that interrupts your breathing when you sleep
- Narcolepsy, a condition that makes you excessively sleepy during the day
Excessive yawning may also be caused by taking medication that makes you very tired.
While excessive yawning may be a symptom of an underlying condition, sometimes it can be a symptom of a serious medical problem. These medical emergencies include:
If you are doing something repetitive or not interesting to you, you might not be able to stop yawning. Tasks like watching television, listening to a lecture, studying, or driving can put you in a low-active state that makes you yawn more.
Thermoregulatory disorders and intense headaches can also cause excessive yawning. Researchers believe this may be caused by a circulatory dysfunction.
Not being able to stop yawning might be your body’s way of showing that your circulatory system isn’t working or that your body can’t regulate its body temperature.
What to Do When You Can’t Stop Yawning
If you start yawning excessively and are not sure why, you should talk to your doctor. Excessive yawning might be caused by an underlying medical condition. It’s a good idea to ask your doctor what may be the cause.
If you’re worried that you can’t stop yawning, you should see your doctor soon. You shouldn’t ignore excessive yawning even though yawning is a common reflex.

What to Do If You Can’t Stop Yawning
Yawning is a phenomenon that affects us all. Even if you’ve managed to clock 8 hours of sleep, you can sometimes find yourself yawning at your desk the following morning. However, there’s more you can do than just get more sleep. Here, we take a look into what causes a yawn and what to do if you can’t stop yawning.
What exactly is a yawn?
Yawning involves a deep inhale of breath, followed by an open-mouthed exhale once the lungs are full. The average yawn lasts roughly six seconds and during this time your heart rate can increase by up to 30%. While yawning feels similar to taking a deep breath, studies have found that the physiological changes that take place are different in terms of heart rate, eye closure, lung volume, and respiration rate.
The average adult yawns roughly 20 times a day and this can start as early as 11 weeks from conception when you are still in the womb.
What causes yawning?
Scientifically there is no strong evidence behind why we yawn, but fatigue, boredom, and contagious yawning all play a big part.
Spontaneous yawning usually occurs when you’re tired. Theories suggest after a lack of sleep there’s less oxygen in your lungs – hence the inhaling of air deeply and slowly. However, there’s little proof to back up this theory.
A more authoritative study suggests that we spontaneously yawn to cool the brain. That’s because pumping air into the brain lowers its temperature. This study monitored brain temperature recordings in rats and found that cortical temperatures were significantly raised until the onset of a yawn, which resulted in temperatures drastically falling for 3 minutes after yawning.
In terms of contagious yawning, the evidence is more concrete. One study found that 50% of participants yawned when watching a video of somebody yawning. Another study also discovered that contagious yawning occurs in families of chimpanzees, macaques, and baboons.
Why is yawning contagious?
Again, there is little understanding behind why we might yawn. Previous research suggests a link between contagious yawning and empathy, suggesting we yawn as a tool of social communication. Evidence to back this up includes those who haven’t developed empathy not yawning contagiously. For example, children under 4 do not yawn after seeing others do it.
However, a 2014 study by Duke University, did not find a strong link between contagious yawning and empathy. The strongest discovery they found was older participants are less likely to contagiously yawn than younger people.
What is considered excessive yawning?
According to Healthline, excessive yawning is yawning that occurs more than once per minute. This can often just be due to a late night, however, if you can’t stop yawning, it might be a sign of certain medical conditions, including:
- A vasovagal reaction (caused by the vagus nerve which regulates your heart and blood vessels)
- A sleep disorder, for example: sleep apnea and narcolepsy
- A side effect of medications treating depression or anxiety
- Bleeding in or around the heart
- A brain tumour
- A heart attack
- Epilepsy
- Multiple sclerosis
- Liver failure
If you’ve noticed a strong increase in yawning, talk to your doctor. They’ll likely ask you to track your sleep habits to rule out the possible cause of lack of sleep. After that, diagnostic tests can help them determine the reason behind your excessive yawning.
How to stop yawning
The treatment to stop excessive yawning is dependent on its cause. For example, if your yawning is due to certain medications, your doctor will likely recommend alternatives. If you can’t stop yawning due to a sleep condition, your doctor may recommend wearing a breathing device overnight.
If you’re healthy but still yawning often, there are certain lifestyle changes you can adapt to help you. This includes exercising regularly, trying to reduce stress, and of course sticking to a regular sleep cycle where you can achieve 8 hours of sleep every night.
If you can’t stop yawning at awkward moments and you’d like an immediate solution to help you stifle it, try one of the following.
1. Lower the temperature
If you lower your body temperature, you’re less likely to want to yawn and inhale the cool air. A 2019 study found that people who wore a cold pack on their neck yawned three times less than those who wore a heat pad over the same time. So, ensure the heating is down or a window is open.
2. Drink something cold
Dehydration can lead to fatigue, which can lead to yawning. If you have an important meeting coming up and you haven’t had a good night’s sleep, ensure you bring some water or juice with you. Ingesting something cold will also help lower your body temperature.
3. Breathe through your nose
It feels like an obvious one, but as yawning involves opening your mouth, try breathing through the nose. Talking to The Healthy, Dr. Robert R. Provine says, “A yawn involves a long inhalation and short exhalation with gaping jaws”. If you seal your lips, you can’t go through the full motions of a yawn.
4. Eat cold foods
As well as trying cold drinks, eating cold foods has the same cooling effect which will hopefully prevent a yawn. If you don’t want to be snacking on something unhealthy, try some fruit that has been cooled in the fridge.
5. Press something cold against you
Sticking to the cold theme, a cool compress against your head can also work wonders. As proven by the experiment mentioned earlier with the cold pack on participants’ necks. Hold this to your head for a minute or two before heading into your meeting.
6. Try public speaking or having the spotlight on you
Another discovery that Dr. Robert R. Provine discusses is that recording people generally stops them from yawning. “There’s a social inhibition effect. People looking at you will inhibit yawning”. Put simply, if you’re being watched you’re less likely to yawn. Why not try putting it to the test!
A final note:
Yawning is most often just a symptom of fatigue, boredom, or a response to those around you yawning a lot. However, if you find yourself yawning more than once a minute, it’s best to see a doctor to rule out any medical conditions. Simple changes like getting a regular night’s sleep and reducing stress is best if you can’t stop yawning.
