The coronavirus has quickly become part of more and more people’s everyday lives. The fear of the virus is probably worse than the virus itself, but, at the same time, we must not ignore people who are afraid. What is particularly frightening is that it is a new virus that we lack immunity against. Since there are no medicines or vaccines, many people wonder how to protect themselves from being infected and how to strengthen their health to be able to fight the virus if they become infected.
The purpose of the article is to give concrete, effective advice to anyone who is concerned for themselves or for other people. Washing your hands, if possible avoiding travelling, and staying at home if you have been in any at risk areas, are all important tips to avoid being infected and reducing the risk of the virus spreading.
But since the virus is spread via the air (ref 1) and settles in the airways, the way we breathe is also important to highlight. In a single day, we breathe in as much as 10-20,000 liters of air. That is a huge amount, and since one liter weighs 0.1 gram it makes up 10-20 kilos of air, in other words about 10 times more than the amount of food we eat. The air contains lots of bacteria, viruses and other particles. In just one day, we inhale up to 100 billion of them according to research at the Karolinska Institute in Sweden.
Face masks may give a false sense of safety
Using a face mask is a measure that is becoming increasingly popular. In China, for example, all residents now receive free face masks. Many doctors, however, recommend NOT using a mask, as it simply does not provide effective protection against small airborne particles such as viruses. Since it is inconvenient, there is also an increased risk of often touching your face with your hands when correcting the mask. Another important consideration is that the most common masks only last for about 3-4 hours before they have to be replaced.
Even worse is that many people who are using a mask, especially children, open their mouths to breathe when using it (see the video below where Chinese parents have filmed their children). The increased air resistance that the mask imposes, probably makes the children feel that it is too hard to breathe through their noses, and because of that, open their mouths. As you can read further down in the article, nasal breathing is one of the most important breathing tips, so using a breathing mask may, at worst, be counterproductive by leading to a false sense of security, but instead, may increase the risk of being infected.
The top five breathing tips
In regards to creating a strong internal environment, there is far more to it than just muscles and willpower. It has been found that improving our breathing habits is very effective in strengthening our inner environment as it affects thoughts, emotions and our physical body and creates the inner calmness required for the immune system to work optimally. Below, are the five most important breathing tips for what you can do to protect and strengthen yourself:
- Breathe through your nose
- Exercise with the Relaxator breathing retrainer
- Breathe through your fears
- Do exercises that create open and well-functioning airways
1. Breathe through your nose
We have four important organs that are exposed to external threats: skin, stomach, nose and lungs. Our skin and stomach have an acidic pH, the skin about 5.5 and the stomach about 1.5-3, which gives effective protection. The lungs, on the other hand, have an alkaline pH of about 7.6, which is a must for enabling the oxygen we inhale to be transferred to the blood. This high pH prevents the lungs from being protected from external particles in the way the skin and stomach are. Because of this, the function of the nose is crucial for protecting the lungs.
The air we breathe in is full of bacteria, viruses, chemicals and other particles. About 75 % of all particles and viruses in the air are filtered out as they pass through the mucous membranes and cilia of our nose. If we breathe through our mouth, the air goes unfiltered into our lungs. In other words, we skip our body’s first line of defense against intruders.
The further down the trachea and into our lungs the particles from the inhaled air end up, the greater the risk of getting inflammation and infections. Given the lungs’ enormous absorption area of 50-100 square meters, about the size of a tennis court, it is critically important that they are kept free of viruses and bacteria.
So if we are taking protective measurements against the coronavirus, it is not enough to wash our hands if we, at the same time, have our mouths open and breathe in 10,000-20,000 liters of unfiltered air every day. It’s a bit like filtering mosquitoes and swallowing camels! You can say that it is as natural to breathe through your mouth as it is to eat through your nose.
Three important reasons why you should breathe through your nose:
1. A COLD NOSE WILL INCREASE THE RISK OF VIRUS INFECTIONS
Our nose can be compared to a highly efficient heat exchanger that warms up and moistens the air. When inhaling, our nose becomes cooled and dry as it moistens and heats the inhaled air, which is usually cooler than our body temperature. When we exhale, the temperature inside our nose is raised, and the area is moisturized by the 37 degree Celsius (98.6° Farenheit) temperature and 100% moist air being returned from the lungs. If we, on the other hand, breathe in through our nose and out through our mouth, the nose will not restore it’s warmth and moisture upon exhalation. And if we breathe both in and out through our mouth, our nose will be constantly cold and dry.
Research shows that the rhinovirus, which is known to cause colds and infections in the upper respiratory tracts, will multiply when the nose cools down. The colder it is in the nose, the more the immune system is suppressed, which will create a favorable environment for the rhinovirus to reproduce (ref 2). Now, we do not know exactly how the coronavirus behaves, but it is not inconceivable that a cold nose offers an environment that is favorable for this virus to also propagate.
2. NITRIC OXIDE IS ANTIBACTERIAL AND ANTIVIRAL
Nitric oxide, or NO, is a very important substance produced in large quantities in the nasal sinuses, which was discovered by Eddie Weitzberg, Jon Lundberg and co-workers at the Karolinska Institute in Sweden, in the mid-1990s (ref 3). When we inhale through our nose, NO accompanies the inhaled air in order to dilate the bronchial tubes to allow the air to pass through easily.
Another important function of NO are its antimicrobial properties which kills viruses and bacteria that have escaped from the cilia inside our nose and throat. The coronavirus belong to the same virus lineage as SARS (Severe Acute Respiratory Syndrome). In a paper from 2005 the researchers concluded that nitric oxide inhibits the replication of the SARS virus (ref 4).
Additionally NO also causes the blood vessels inside our lungs to dilate, which allows oxygen to be transferred to our blood more easily. When we breathe in through the mouth, the air is not spiked with this important substance.
3. CARBON DIOXIDE IS ANTIBACTERIAL
When we breathe through our nose the carbon dioxide pressure in our body increases, since nasal breathing slows down the respiration rate, and thereby more CO2 is retained in our body. CO2 has been used in food packaging since the 1930’s, because of its antibacterial effect, which prevents disease-causing bacteria from growing. Bread, cheese, chicken, and coffee, are some of the products that have 100 percent carbon dioxide added inside the packaging.
A study at the Karolinska Institute showed that the growth of staphylococci was 1,000 times higher when the bacteria were exposed to normal air for 24 hours, compared with exposure to air saturated with 100 percent CO2 (ref 5).
In an article in Nature from 2019 an Australian research group demonstrated how water that is exposed to carbon dioxide, is an efficient way to inactivate virus and bacteria (ref 6).
A Swedish research group led by Professor Jan van der Linden has in several publications showed how exposing open surgical wounds to 100% carbon dioxide reduces the risk of infection of the wound (ref 7).
CONNECTION BETWEEN MOUTH BREATHING AND PNEUMONIA
Infections in the airways and pneumonia are important characteristics of the people infected by the coronavirus. Pneumonia is usually bacterial or viral. Even though it is speculation, as more research is needed, it is not unthinkable that the antibacterial and antiviral properties of NO and carbon dioxide have contributed to the fact that the three women below, thanks to improving their breathing, no longer experience any pneumonia or infections in the airways.
UNBLOCK A STUFFY NOSE
“But I cannot breathe through my nose,” you may say. “It is often stuffy or the nasal passages are tight.” One of the effects of mouth breathing is that a nose that is not used will eventually stop working properly, much like the phrase “if you don’t use it, you lose it.”
Reduced airflow through the nose gives rise to lower air pressure, which over time will make the nasal passages regress and decrease in size, which was confirmed by a study on patients who had undergone laryngectomy and were breathing through the throat (ref 8). A stuffy or tight nose is often a sign that breathing is not optimal. In the nose, under the nasal turbinates, there is erectile tissue. As your breathing improves, the erectile tissue will decrease in size and the inside of the nose will feel less crowded.
The narrowing of airways and nasal passages and a stuffy nose is a logical adaptation as it is our body’s defense mechanism to maintain an optimal carbon dioxide pressure. Carbon dioxide is produced in the body, and virtually all carbon dioxide leaves the body through exhalation. In the event of a deficiency, the body tries to reduce the outflow by narrowing the airways.
As you begin to improve your breathing, breathe through your nose and build up more carbon dioxide in your body, your nose will automatically become less tight as the defense mechanism is no longer needed. Read more in the article – How to unblock a stuffy nose >>
TAPE YOUR MOUTH AT NIGHT
To ensure that you only breathe through your nose when asleep, you can tape your mouth with Sleep Tape. It may sound strange, but I recommend everyone to try it. A good night’s sleep is vital to our health. During sleep our body heals, repairs and regenerates. How we breathe when we sleep is of great importance, especially given the large number of hours we sleep every night.
The feedback I frequently get is that people wake up more alert in the morning, sleep more calmly, don’t wake up during the night, and need less sleep. This is what one woman said: –My nose has been stuffy almost every morning, and I loved the tape from day one. Already on the first morning my nose was freer and I had slept really well. Will never stop taping my mouth!
If you sleep with an open mouth your breathing will automatically exceed your body’s needs. This low-grade form of hyperventilation not only causes oxygen deficiency but also increases the risk of getting unwelcome particles into the lungs. Taping your mouth at night is a remarkably simple and inexpensive way to ensure that your mouth stays closed and respiration occurs only through your nose. This will make breathing work for you instead of against you.
You may think it sounds barbaric, or feel uncomfortable with the idea of applying tape to your mouth — a common reaction among the participants in my courses. The discomfort is generally just a mental block, and after trying it out for a few minutes most people find it to be completely harmless. If you do feel discomfort, I suggest you start to apply the tape during the day, for example 15 minutes before bedtime for a few evenings, in order to become more comfortable with the sensation.

Don’t have any Sleep Tape? No problem, many use surgical tape which you can get from your local pharmacy. Even freezer tape and band aid will work according to some.
2. Hum to increase air circulation and NO production
Impaired breathing leads to poor air circulation and lower pressure in the nose and sinuses, thus creating an environment beneficial for bacterial growth and inflammation. Studies done at the Karolinska Institute in Sweden show that a humming sound leads to a dramatic increase of the airflow in the sinuses. Further the levels of nitric oxide (NO) increases 15- to 20-fold by humming compared with quiet exhalation. NO is known to be broadly antifungal, antiviral and antibacterial.
Read more in the article – Humming can eliminate sinusitis >>
Here is a simple hum exercise.
- Close your mouth and let the front part of the tongue rest in its natural place in the roof of the mouth, behind the front teeth.
- On exhalation say, ”Hmmm…” In other words, push together your vocal cords and squeeze the air out through your nose so that a humming sound occurs.
- You can feel the vibrations slightly in your jaw. The vibrations increase the air circulation and the production of NO in your nose and sinuses.
- In a chronically blocked nose or sinusitis repeat for 20-40 breaths (approx. 5-10 minutes) 2-4 times a day for a few days or until the problems are resolved.
To increase the effect you can, while humming, massage the area around your nose, temples and above your eyes (since we have sinuses there as well). If you have a sore throat, you can massage your throat and the root of your tongue. The massage stimulates the blood circulation in these areas. The throat massage also stimulates the vagus nerve which is directly coupled to our rest and digest system (the parasympathetic part of the autonomic nervous system).
The exercise could also be done preventively, for example when you are about to get a cold, or just being in the mood to do it.
3. Improve your breathing with the Relaxator Breathing Retrainer
The Relaxator Breathing Retrainer provides an adjustable resistance on your outbreath so that your exhalation is prolonged. This lays the foundation for rhythmic, slow, low and small breathing. When you are breathing in a way that is not optimal, your body suffers from a lack of oxygen. Your brain, heart, muscles and eyes are all major consumers of oxygen, and poorer oxygenation has the greatest negative impact on these organs and functions. With the Relaxator, the air ends up in the midriff to a greater extent, which results in a more efficient oxygen uptake.
This is what one person said: “I have a cold and have had a stuffy nose and have not been able to sleep well the last nights because of that. Tonight, when I woke up for the fifth time, I decided to try using the Relaxator. Since I could not breathe in through my stuffy nose, I had to breathe in through my mouth and out through the Relaxator. After a while, my nose was cleared so that I suddenly could breathe through it. I continued for a while with the Relaxator, but soon enough I fell asleep and then slept all night!”
Don’t have a Relaxator? No problem, you can exhale through a straw, pursed lips or tighten the muscles in your throat and wheeze the air out, so called ujjay-breathing.
Five important benefits from using The Relaxator:
1. STRENGTHENS THE BREATHING MUSCLES
Our breathing muscles consist of the diaphragm, as you can see in the picture, as well as muscles in the abdomen, chest, neck and shoulders.
At rest, 70-80 percent of muscular activity at inhalation should be with your diaphragm, which makes it by far our most important breathing muscle. In fact, the heart and the diaphragm are the only two muscles in our body that never rest. They are constantly active, the heart with pumping blood and the diaphragm with moving the air in and out of our lungs.
When we use the Relaxator, the resistance on the exhale exercises the diaphragm and other breathing muscles. When they are working better, the gas exchange becomes more efficient.
The gas exchange, the process in which the body absorbs oxygen and gets rid of carbon dioxide, takes place in the alveoli in the lungs. When we are sitting or standing, there is, thanks to gravity, most blood in the lower part of our lungs. Most of the alveoli are also located in the lower parts. If the inhaled air ends up far down in our lungs, it will provide a more efficient gas exchange. The large amount of blood and alveoli facilitates for the oxygen to be transferred to our blood and the carbon dioxide to be transferred from our blood to our lungs for exhalation.
2. INCREASES AIR CIRCULATION IN THE LUNGS AND NOSE
Breathing where the inhaled air ends up high up in the chest does not only provide an inefficient gas exchange. It also ensures that the air further down in the lungs becomes confined and stale, as it gets trapped because the air doesn’t circulate.
An optimal airflow in the lungs is like the water in a rippling creek. When the air gets trapped, which happens in narrow airways, mouth breathing and shallow breathing, the air is closer to the water in a pond, stagnant and stale.
When the air circulation deteriorates in our nose, sinuses and lungs, an environment is created that sets the stage for viruses and bacteria to multiply more easily. Resistance breathing with the Relaxator increases the pressure in our nose and sinuses, which leads to increased air circulation.
3. REDUCES STRESS, WHICH BOOSTS THE IMMUNE SYSTEM
Why is it so common for us to get sick before weekends or holidays? Well, then we relax and reduce the internal stress, which, in turn, makes the immune system more active.
Our immune system is almost as complex as our nervous system, and its task is to neutralize invaders in our body. When we experience stress, our immune system is suppressed. This is why stress hormones are given to people who have undergone organ transplants. As the new organ is perceived as an invader, the role of the stress hormones is to weaken the immune system to the point where it doesn’t repel the organ.
An extreme example can be found in the book Man’s Search for Meaning by Viktor Frankl, who survived three years in concentration camps. When he was deported to Auschwitz, it began with a four-day train journey in a narrow carriage and only one meal during the long journey. When they arrived 90% of the new arrivals were sent directly to the gas chamber. The 10% not selected for death would experience the intense stress of witnessing the execution of their fellow men and women seen in meter-high flames of fire bursting out of the chimneys. Those who survived would have to undress and have their entire body shaved while standing outside in the late autumn cold stark naked and wet after the shower. There was the heavy and dark awareness that the slightest offense would lead to immediate hanging. After experiencing all of this stress during the day their sleeping conditions were extremely unfavorable with nine people in a 2 x 2.5 meters bunk. Despite these extreme physical and mental stresses, they would wake up the next day without even having got a cold.
When you exhale through the resistance of the Relaxator, exhalation is prolonged, which reduces stress. Exhalation is linked to relaxation, and by prolonging exhalation your body’s ability to relax and ease off is increased. An extended exhalation will also have a positive effect on our inhalation, as the air reaches the lower parts of our lungs. The breathing also slows down. Low and slow breathing is the opposite to the shallow and rapid breathing that is strongly associated with stress.
4. STIMULATES THE LYMPH FLOW – OUR SEWER SYSTEM
A system that depends on the movement of the diaphragm is the lymphatic system. All organs in our abdomen emit waste products, and our lymphatic system, which is an important part of our immune system, has the task of removing the waste. We have more lymphatic fluid than blood in our body, but unlike our blood, which is pumped around the body by our heart; our lymph fluid lacks its own pump, which is why lymphatic fluid is dependent to a large extent on muscular activity. Therefore, the movement of our diaphragm is very important for our lymphatic system, especially since it never rests and is working 24/7.
When you are breathing fast and shallowly, the pressure in your midriff decreases, which impairs your posture. This becomes particularly obvious when sitting down, which many of us are doing way too much. As we’ve mentioned before, chest breathing leads to a reduction in blood oxygenation. When the movement of our diaphragm is reduced, the ability of our lymphatic system to remove residual products from the abdomen is also diminished.
5. BALANCES THE NERVOUS SYSTEM, WHICH PROVIDES BETTER ENERGY MANAGEMENT
The part of the nervous system that controls involuntary functions, such as muscles in the blood-vessels and airways, heartbeat and digestion, is called the autonomic nervous system. It is divided into a sympathetic, activating part and a parasympathetic, calming part.
The sympathetic part prepares the body for increased activity and is active during fight or flight response. The parasympathetic part influences rest, recovery and energy saving.
High sympathetic activity is like driving down the freeway at 80 miles per hour (130 km/h); we have tunnel vision, and to a large extent we react instinctively to what is happening. We end up in conflicts more easily and view the world through glasses that make us perceive it as threatening, and we feel worried and afraid.
If we, in our daily lives, operate mainly from sympathetic stimulation, it means that we are spending more energy than necessary. We all know what it’s like to be sick and powerless. The reason is that all our energy is used by the immune system to fight the invaders that make us sick. Breathing retraining with the Relaxator is an effective way to unlock the turbo so that we do not engage our stress system more than necessary and, thus, can save energy so that the immune system can do its job.
4. Breathe through your fears
What is the price for holding back emotions or dwelling on old conflicts? Clearly, it is not free.
– What will happen if I’m holding out my hand for a while? – Nothing.
– Exactly, but what will happen if I am holding out my hand for an hour? – You will get tired.
– Yes, and what will happen if I am holding out my hand for a day? – You will get super tired and get cramps.
– Mmm, with all certainty. What if instead of an empty hand I am holding out a kettlebell that weighs 10 kg? – You will get really tired after just a little while!
This is how your body works. It wastes a lot of energy when you hold on to anger, worry, grief, fear, traumas and so on. The more powerful they are, the more energy they will consume.
There is a price to pay to try to be one step ahead in order to avoid people and situations that may trigger fear, worry etc. And all the junk food, cigarettes, alcohol, drugs and so on that we consume to deafen what is fretting inside us also has a price tag. The energy leakage suppresses our immune system, as it is such a large consumer of energy.
When we are afraid and worried, we also get stressed, which weakens our immune system even more. Read more about how your fears can be crippling energy thieves in the article how I conquered my fear of public speaking.
BOTTLED-UP EMOTIONS WEAKEN US
In an interesting study, the participants were divided into two groups, where one group was instructed to hold back their emotions while the other group was encouraged to stay in touch with their emotions. Then, they got to see the same movie.
After the movie, they were asked to squeeze a hand strengthener as many times as they could. It turned out that those who held back their emotions were significantly weaker than those who had stayed in touch with them. In other words, we are leaking energy when we are holding back what we really believe, think and feel.
You’ll find more information in the article – Breathe through your fears >>
EXERCISE PART I: LIST YOUR FEARS
By letting your breathing assist you, you may experience the safety needed to dare to face your fears, sorrows and traumas instead of fleeing from them. When you reduce your fear of saying, “I’m sorry,” speaking in public, or standing up for what is important to you, you will also grow as a human being.
Set aside 5-10 minutes and write down a list of the situations or people who are or have made you scared, upset, pissed off, annoyed or stressed, big or small. Ask yourself questions like: “What scares me the very most today? What scared me the most when I was little? Was there anyone physically or emotionally abusive in the past that made my upbringing difficult?”
Do not be afraid to go back in time and dig deep, as we, namely, have the ability to repress what has happened to us that we perceived as tough.
EXERCISE PART II: BREATHE THROUGH YOUR FEARS
The exercise will help you to dare to face your fears and make them diminish or cease altogether. The exercise will also make you feel safer and braver whenever you move outside of your comfort zone.
By maintaining a rhythmic, slow and low breath, you get the courage needed to dare to remain in your fears for a longer period of time.
- Set aside 5-10 minutes.
- Select one or a few situations and/or people from the list you wrote above. Make them as alive as possible by fantasizing vividly with adding colors, sounds, moving images and other people. Feel the places in your body where there is tension and dis-ease. Allow your emotions to become increasingly clearer.
- Notice how you are breathing while experiencing these difficult things. If your breathing is stressed and tense, it is completely natural. If you have difficulty getting in touch with your fears, you can be helped by your breath by breathing fast and shallow high up in your chest, or holding your breath altogether.
- Now, make your breathing rhythmic, low and slow by prolonging your exhalation. Your friend, the breath, is with you all the time and allows you to feel calm and safe in the midst of all the hard things. It would be beneficial to use the Relaxator now.
EXERCISE PART III: REFLECT ON YOUR FEARS
Finish the exercise by reflecting on your fears for 5-10 minutes. Be curious about where the fears come from. In what way do they want to protect you? What benefits do they provide? What can you learn from them? What insights can they give you? The fears you experience have a purpose. It may be to protect you, but it may also be to help you gain new insights.
Perhaps the reflection will raise questions like, “How do I REALLY want to live my life? What does my body need to heal? and What decisions do I need to make in order to get inner peace?”
By starting to unravel your fears, you may discover what lies behind them. Your answers to these questions may be something like, “I must get a divorce.” “I need to speak to my father.” or “I must start painting again.”
5. Exercises to create open and well-functioning airways
The six exercises below aim to open your airways, get them functioning well and strengthen and relax your breathing muscles. Pick a few exercises that appeal to you and put together your own 10-minute workout program. You can do your exercises daily or at times that are convenient for you.
Add a few calm breaths between the exercises, and reflect on how it feels in your body before moving on to the next practice. Keep your back erect and straight during the exercises, as this facilitates the work of the diaphragm and lowers the breathing. Breathe in a relaxed way, taking slow, low, calm, and rhythmic breaths.
It is an advantage to use the Relaxator as it helps you maintain good breathing during the exercises. The exercises will help you improve the way you breathe in your daily life, where you are breathing more and more of the daily 20-25,000 breaths in accordance with the seven good habits of Conscious Breathing: nose, abdominal, slow, small, upright posture, rhythmic and quiet. If you manage to maintain an upright posture with relaxed breathing during these exercises, chances are that you will manage this in more and more situations in your everyday life.
