Patrick McKeown is one of the top teachers of the Buteyko method — a breathing method named after the Russian physician who developed it. McKeown has been teaching the Buteyko Breathing Method full-time in his native Ireland and abroad for over a dozen years.
As he notes in the featured TED Talk, breathing is typically an ignored topic when it comes to health, yet breathing properly can improve oxygenation through your body, including your brain, and is a powerful strategy for relieving stress and anxiety.
Two of the most common breathing problems are over-breathing and mouth breathing, both of which have adverse health consequences.
Mouth breathing even alters your facial structure, causing your facial features to narrow and droop downward. Narrow and set back jaws increase the risk of developing lifelong obstructive sleep apnea.1
In the video below, McKeown reviews the many problems associated with mouth breathing specifically, and the importance of addressing mouth breathing early in childhood, as it can have lifelong repercussions.
Nose Breathing Is Key for Good Health and Stress Management
Most people will tell you to take a deep breath to calm yourself down. However, this strategy can actually have the opposite effect.
When you’re stressed, your breath becomes faster, deeper and noisier, you breathe more often through your mouth and you tend to breathe with your upper chest rather than your diaphragm.
As noted by McKeown, it simply doesn’t make sense to amplify your current breathing pattern if you want to bring yourself from a state of stress to a state of calm. To induce calm, you need to breathe slowly, using the diaphragm. You also want to breathe less, and breathing through your nose is key.
Your nose actually directs 30 different functions in your body. Nerves in your nasal passages (which connect to your hypothalamus) sense everything about your breathing and use that information to regulate your bodily functions.
For example, your nose releases nitric oxide (NO) during breathing, which is carried from your nose into your lungs. NO is a gas that plays a significant role in homeostasis (maintaining of balance) within your body.2,3,4,5,6
NO also sterilizes the air carried into your lungs, opens up the airways and increases the amount of oxygen taken up in your blood. You were born to breathe through your nose, yet many develop dysfunctional breathing patterns that lead to mouth breathing.
This in turn can result in other health problems, including asthma. As a result of feeling like you’re not getting enough air, asthmatics tend to breathe heavier, and when you increase the breathing volume coming into your lungs, it causes a loss of carbon dioxide (CO2).
The Importance of Carbon Dioxide Homeostasis
Contrary to popular belief, CO2 is not merely a waste gas. Although you breathe to get rid of excess CO2, it’s important to maintain a certain amount of CO2 in your lungs, and for that you need to maintain a normal breathing volume.
When too much CO2 is lost through heavy breathing, it causes the smooth muscles embedded in your airways to constrict. When this happens, there is a feeling of not getting enough air and the natural reaction is to breathe more intensely.
But this simply causes an even greater loss of CO2, which constricts your airway even further. In this way, asthma symptoms feed back to the condition, and to remedy the situation you need to break this negative feedback loop by breathing through your nose and breathing less.
Also, while most believe that taking bigger breaths through your mouth allows you to take more oxygen into your body, which should make you feel better and more clear-headed, the opposite actually happens.
Deep breathing tends to make you feel a bit light-headed, and this is due to eliminating too much CO2 from your lungs, which causes your blood vessels to constrict. So, the heavier you breathe, the less oxygen is actually delivered throughout your body.
Overbreathing and mouth breathing also tend to go hand-in-hand with snoring and/or sleep apnea; conditions that decimate your sleep quality. This too contributes to the downward health spiral associated with improper breathing.
Less Is More When It Comes to Breathing
Breathing through your nose and breathing less is the answer to all of these problems. According to medical textbooks, normal breathing volume is between 4 and 7 liters of air per minute, which translates into 12 to 14 breaths.
Clinical trials involving asthmatics show they breathe between 10 to 15 liters of air per minute,7,8 and people with chronic heart disease tend to breathe between 15 to 18 liters of air per minute.9,10,11,12
This suggests breathing less is a sign of better health. Conversely, the more you breathe, the more likely you are to experience significant health problems. Your tolerance to CO2 is part of this equation, as good CO2 tolerance equates to higher levels of health and fitness.
When your body and brain have a normal CO2 tolerance, your breathing will be light and smooth as your body is not constantly trying to rid itself of excess CO2. Contrary to popular belief, the primary stimulant signaling your body to take a breath is not lack of oxygen; it’s an excess CO2.
“Oxygen only drives your breathing when oxygen levels drop to about 50 percent, and that would be quite an extreme situation. So, your body breathes to get rid of the excess gas, CO2,” McKeown explains.
You always need a certain amount of CO2 for normal functioning. If you have normal CO2, you will have good tolerance to it, which translates into a higher breath-hold time (the length of time you can hold your breath). Also, when you exercise, your body generates more CO2, and if you have good tolerance to it, your breathing rate will remain much lower than someone who has a poor tolerance to CO2.
How to Improve Your Blood Circulation and Lower Stress Through Proper Breathing
In his talk, McKeown leads a group demonstration of proper breathing, summarized as follows:
•Place one hand on your upper chest and the other on your belly; feel your belly move slightly in and out with each breath, while your chest remains unmoving.
•Close your mouth and breathe in and out through your nose. Focus your attention on the cold air coming into your nose and the slightly warmer air leaving it on the out breath.
•Slowly decrease the volume of each breath, to the point it feels like you’re almost not breathing at all (you’ll notice your breath getting very quiet at this point). The crucial thing here is to develop a slight air hunger. This simply means there’s a slight accumulation of carbon dioxide in your blood, which signals your brain to breathe.
After three or four minutes of air hunger, you’ll start experiencing the beneficial effects of CO2 accumulation, such as an increase in body temperature and an increase in saliva. The former is a sign of improved blood circulation; the latter a sign that your parasympathetic nervous system has been activated, which is important for stress reduction.
When you’re breathing properly, your breath will be so soft, quiet and light. It will not be visibly or audibly noticeable. By slowing down the speed of your breathing to the point where the hairs in your nose barely move, you can more easily enter into a calm, meditative state. Breathe less air into your lungs than what you were breathing before you started the exercise.
The air shortage should be tolerable and not at all stressful. If the air shortage is too much, take a break from the exercise for 15 seconds or so before resuming to it again. This type of breathing will also help lower your blood pressure, and can be a useful technique to address hypertension without drugs. You may also notice that you have less nasal congestion, allowing for easier breathing.
Breathing Exercise to Quell Panic Attacks and Anxiety
Another breathing exercise that can help if you’re experiencing anxiety or panic attacks, or if you feel very stressed and your mind can’t stop racing, is the following. This sequence helps retain and gently accumulate CO2, leading to calmer breathing and reduced anxiety. In other words, the urge to breathe will decline as you go into a more relaxed state.
- Take a small breath into your nose, a small breath out; hold your nose for five seconds in order to hold your breath, and then release to resume breathing.
- Breathe normally for 10 seconds.
- Repeat the sequence several more times: small breath in through your nose, small breath out; hold your breath for five seconds, then let go and breathe normally for 10 seconds.
How to Practice Buteyko Breathing Daily
The good news is you can improve your CP time by regularly performing the breathing method outlined below. For a demonstration, see the above video. For each five-second increase in CP, you will feel better and improve your exercise endurance.
While this exercise is perfectly safe for the vast majority of people, if you have any cardiac problems, high blood pressure, are pregnant, have type 1 diabetes, panic attacks or any serious health concern, then please do not hold your breath beyond the first urges to breathe. The following exercise is also very effective for decongesting your nose in just a few minutes:
- Sit up straight.
- Take a small breath in through your nose and a small breath out. If your nose is quite blocked, take a tiny breath in through the corner of your mouth.
- Pinch your nose with your fingers and hold your breath. Keep your mouth closed.
- Gently nod your head or sway your body until you feel that you cannot hold your breath any longer.
- When you need to breathe in, let go of your nose and breathe gently through it, in and out, with your mouth closed.
- Calm your breathing as soon as possible.
Repeat this exercise several times in succession, waiting about 30 to 60 seconds in between rounds. Be sure to do it on a regular basis, ideally daily. The fastest way to increase your CP is by learning to be mindful of your breathing on a moment-to-moment basis:
- Always keep your mouth closed for breathing, even during exertion. If you’re exercising or exerting yourself to the point you have to open your mouth to gasp for air, slow down and avoid exerting yourself beyond the point where you can no longer breathe through your nose. This will help you avoid the hazards associated with overbreathing during exercise, such as doing damage to your heart.
- Even when you breathe through your nose, try to breathe more lightly than you normally do; you should not be able to see your breathing in your chest or abdomen.
- Control your breathing all of the time, especially in stressful situations.
