Nasal Breathing – Why breathe through your nose?

Breathing is an essential part of living and yet we don’t think twice about it. It is unconsciously controlled by our brain which automatically determines the rate and depth of breathing depending on our current needs.

How are you breathing right now? Through your nose? Through your mouth? Both? It is important to think twice and pay attention to how we breathe!

So what is nasal breathing?

We have two air passageways to the lungs — the nose and the mouth. Healthy people use both their nose and their mouth to breathe, however, there are many health advantages to breathing through your nose, instead of your mouth. That is because nasal breathing is more natural and helps your body effectively use the air you inhale. Breathing through your nose can help filter out dust and allergens, boost your oxygen uptake, and humidify the air you breathe in.

Mouth breathing, on the other hand, can dry out your mouth. This may increase your risk of bad breath and gum inflammation. Mouth breathing may also make you more prone to allergies, asthma, and coughing. Breathing through the mouth all the time, including when you’re sleeping, can lead to health problems. Although we have needs for both nose and mouth breathing, ie.when you are exercising strenuously or are congested due to a cold or allergies, here are some benefits to breathing through your nose rather than your mouth.

What are the advantages of nasal breathing?

Advantages of Nasal Breathing:

Nasal breathing helps fight off infection. It acts like a filter and retains small particles in the air, including pollen. The nose adds moisture to the air to prevent dryness in the lungs and bronchial tubes. The nose also warms up cold air to body temperature before it gets to your lungs.

Helps improve dental health and hygiene. When you breathe through your nose, the tongue sits at the roof of your mouth and shapes the roof of your mouth. When you breathe with your mouth, your tongue falls to the bottom. The tongue shapes the hard palate of your mouth which affects the spacing and alignment of your teeth as they grow. Nasal breathing also helps with dental health by not breathing in bacteria through your mouth

Nasal breathing makes you stronger. It requires for more effort to inhale through your nose allowing your diaphragm to engage and increase intra abdominal pressure. This pressure creates a support mechanism for your lower back so we can increase stability and engage more effectively. You are then able to lift heavier, thus making you stronger.

It improves the quality of our sleep. Nasal breathing allows the tongue to sit at the roof of our mouth creating a larger and non-obstructed airway to maximize the air that we take in as we sleep.

Diaphragmatic Breathing:

There are many breathing techniques that can help bring awareness to the body, increase oxygen uptake and bring focus. Diaphragmatic breathing is one effective technique that will help strengthen the diaphragm and increase the intra abdominal pressure. This will decrease the work of breathing by slowing down your breathing rate, which will decrease the oxygen demand, requiring less effort and energy to breathe.


Lie down on your back with your legs straight.

Place one hand on your chest and one hand on your stomach.

Take 4 full breaths and check:

Are you breathing in and out through your nose or mouth?

Which hand is rising up as you inhale, chest or stomach?

Is there expansion of your abdomen and rib cage?

Is your exhale longer than your inhale?

You want to inhale and exhale through your nose and feel your stomach to rise and your rib cage expand (inhale as if you’re filling up like a balloon). As you exhale, it should be a little longer than the inhale and you should empty/deflate as much air as you can before inhaling again. Try this exercise for 5-10 minutes a day and gradually increase the time to improve diaphragmatic breathing.

There are many types of breathing techniques and practices that are great for your health but the first step is to be aware of our own breathing. Becoming aware of our own breathing habits and retraining ourselves is an easy way for us to start taking care of our health. Having a proper breathing pattern can help the body relax and realign the body.

How To Choose One Contra Angle Handpiece

A contra angle handpiece is a type of dental handpiece that is commonly used in dental procedures. It is a specialized tool that is designed to provide dentists with precise control and maneuverability during a range of dental procedures.

A contra angle handpiece is typically attached to a dental drill or other rotary dental instrument. It is composed of a number of different components, including a body, a chuck, and a contra angle head. The body of the handpiece is typically made from a durable, lightweight material, such as aluminum or stainless steel. The chuck is a mechanism that is used to hold the dental instrument in place, and the contra angle head is the part of the handpiece that rotates at high speeds.

One of the key advantages of a contra angle handpiece is its ability to provide dentists with enhanced control and precision. The contra angle head of the handpiece allows the dentist to maneuver the dental instrument into difficult-to-reach areas of the mouth, such as the back molars or the upper premolars. This allows the dentist to perform procedures with greater accuracy and precision, which can help to reduce the risk of complications and improve the overall quality of the dental work.

In addition to providing enhanced control and precision, contra angle handpieces are also known for their durability and reliability. The body of the handpiece is typically made from high-quality materials that are resistant to wear and tear, and the contra angle head is designed to withstand high speeds and repeated use without breaking down or wearing out. This means that dentists can rely on their contra angle handpieces to provide consistent, reliable performance during a wide range of dental procedures.

Contra angle handpieces are used in a variety of different dental procedures, including tooth preparation, cavity filling, and root canal therapy. They are also commonly used in cosmetic procedures, such as teeth whitening and veneer placement. Some of the specific benefits of using a contra angle handpiece during these procedures include:

Improved access to difficult-to-reach areas of the mouth: As mentioned earlier, the contra angle head of the handpiece allows dentists to maneuver the dental instrument into tight spaces and difficult-to-reach areas of the mouth. This allows them to perform procedures with greater accuracy and precision, which can help to reduce the risk of complications and improve the overall quality of the dental work.

Enhanced comfort for the patient: Contra angle handpieces are designed to be lightweight and easy to handle, which can help to reduce fatigue and discomfort for the dentist during long procedures. This can also help to improve the overall patient experience, as the dentist will be able to work more efficiently and comfortably.

Reduced risk of tissue damage: The high-speed rotation of the contra angle head allows dentists to perform procedures with greater precision and control. This can help to reduce the risk of tissue damage and other complications, which can improve the overall quality of the dental work and reduce the need for follow-up procedures.

Improved efficiency and productivity: Contra angle handpieces are designed to be fast and efficient, which can help dentists to complete procedures more quickly and efficiently. This can help to improve the overall productivity of the dental practice, as dentists will be able to see more patients in a given period of time.

In conclusion, contra angle handpieces are an essential tool for dentists who need to perform procedures with precision and control. These handpieces are durable, reliable, and easy to use, and they provide a number of benefits for both the dentist and the patient. Whether you’re a dentist looking to improve the quality of your dental work, or a patient seeking the best possible care, a contra angle handpiece can be an invaluable tool.

Euthanasia in Malaysia: Does it Bring Harm or Immoral?

According to Pearsall & Trumble, euthanasia is explained as ‘the bringing about of a gentle and easy death for someone suffering from an incurable and painful disease or in an irreversible coma’. Oxford Dictionary defines euthanasia as gentle and easy death: bringing of this especially in the case of incurable and painful diseases.

Euthanasia has always been a controversial topic in Malaysia. This article will discuss euthanasia from the moral perspective and its legal effect in Malaysia and Canada. The way euthanasia is carried out in Malaysia and Canada will be compared. Although both are commonwealth countries, a line can be drawn between them because euthanasia is illegal in Malaysia but legal in Canada.

Euthanasia in Malaysia context

In Malaysia, no laws specify the legal consequence of euthanasia. Meanwhile, there is a law in Penal Code that deal with culpable homicide amounting to murder. Section 300 of the Malaysian Penal Code states that murder is constituted if the act that results in death is carried out with the aim to do so. In certain circumstances, it involves active voluntary euthanasia where culpable homicide is not murder when the victim over 18 years old is giving consent to suffer death, or takes the risk of death. This fall under exception 5 of section 300 Penal Code.

In other way to say it, the provision of euthanasia is not clearly defined in any Malaysian written law and the action of euthanasia itself (culpable homicide amounting to murder in the Penal Code) is illegal.

Euthanasia in Canada context

Canada is one of the countries legalized euthanasia by allowing doctor to kill patient by drugs. The Canadian Parliament passed federal legislation in June 2016 that enables eligible Canadian people to seek medical assistance in dying (MAID). There are only physicians dan nurse practitioners can provide MAID to eligible person who has a grievous and irremediable medical condition. Additionally, their death had to be “reasonably foreseeable,” and at least two physicians had to agree with the request for euthanasia.

Later, the law was amended to permit those who are not terminally ill to choose death, greatly expanding the pool of candidates. In 2021, the Government of Canada announced that changes to MAID officially came into effect. MAID cases have increased 32.4% from 2020 to 2021. There were 10,064 euthanasia deaths recorded in 2021.

John Stuart Mill’s view

John Stuart Mill was the most influential English language philosopher of the nineteenth century. He wrote in “On Liberty” (1859): The only purpose for which power can be rightfully exercised over any member of a civilized community, against his will, is to prevent harm to others. His own good, either physical or moral, is not a sufficient warrant. He cannot rightfully be compelled to do or forbear because it will be better for him to do so, because it will make him happier because in the opinion of others, to do so would be wise, or even right.

Mill defended individual freedom in matters of private morality. According to Mill, an action should only be prohibited by law to prevent “harm” to others. Mill rejects the reasons such as doing something based on benefit or goodness to the person himself. In the field of criminology, there is a category of crime called victimless crime. For example, killing a terminally ill person (euthanasia). Those who do so voluntarily and the act is considered immoral not because of “harm” to others but the act itself is considered immoral.

Writer’s view on euthanasia

Euthanasia is a double-edged sword. It can bring both good and negative effects. The people in favor of euthanasia contend that it enables terminally ill people to leave this world peacefully and with dignity, and they contend that society should support individuals’ right to choose euthanasia. People should be able to choose their own death date and location because it is immoral to make individuals endure severe pain and suffering since doing so infringes their rights to personal freedom and human dignity.

On the other side, some people think that the suffering of people with terminal illnesses would be reduced if euthanasia was made legal in Malaysia. Making terminally ill people undergo severe pain would be cruel and unjust.

In conclusion, euthanasia is morally incorrect by looking at the view of Mill although it does not bring harm to others. Every country has its own jurisdiction and law on euthanasia. The legislation of euthanasia in Malaysia, either the Penal Code or any new law governing euthanasia should be updated frequently in order to benefit people to the greatest extent.
