Breathe in …Breathe out…

These poses are very effective in lung cleansing and strengthening chest muscles. If one is practicing a layered asana such as Surya Namsakar, it has major detoxifying effects on our internal organs as well as brings about a sense of relaxation…writes Deepak Mittal

Breathing is necessary for survival. When you breathe properly, it reduces stress and boosts your immunity, allowing you to stay healthy. Regular and dedicated Pranayama and Yoga practise is one of the most important ways to improve your breathing capacity and prowess. These two holistic practises offer numerous techniques or asanas to increase one’s lung capacity and that of the entire breathing system, lowering the chances of contracting respiratory problems and/or reducing their impact, if they exist. As a result, a thorough, long-term practise of the healing therapies of Pranayama and Yoga should be on everyone’s to-do list if they want to stay healthy.

How to know if you have a respiratory issue?

Asthma, pneumonia, chronic obstructive pulmonary disease (COPD), tuberculosis (TB), bronchitis, and lung cancer are the most common types of respiratory diseases. A majority of respiratory disease symptoms are also fairly common, including shortness of breath, a persistent nagging cough, chest pain, and blood in your sputum, also known as hemoptysis.

It’s important to remember that people with asthma typically exhibit symptoms such as coughing with sputum, general tiredness, and a reliance on seasonal changes. On the other hand, common TB patients exhibit symptoms such as cough with sputum, hemoptysis, and weight loss, whereas COPD patients exhibit cough with sputum and major fatigue, which worsens over time if not treated properly. If you or someone you know is experiencing any of these symptoms, please see a lung specialist right away.

How Yoga & Pranayama can help?

Yoga is based on five principles: positive thinking and meditation, relaxation, exercise, Pranayama, and a nutritious diet. Controlled breathing, also known as Pranayama, is a technique known to increase our lung capacity and overall bodily functions through regular practise by controlling inspiration and expiration. The technique makes use of diaphragmatic and abdominal muscles, which improves the human respiratory system. Regular practise of Pranayam techniques such as Kapalbhati, Nadisuddi, Bramhari, Bhastrika, and others has been shown to benefit practitioners. And we must do them on a regular basis if we want healthy lungs that will last a lifetime.

In addition to Pranayama, if one practices the yogic exercises known as Yogic Asanas, the benefits accrued are multi-fold. This form of exercise connects our body to our heart and soul, and puts us back in touch with our inner being. This way, we are the first to know if we are feeling out of balance and unwell, thus we can look at how to rectify the situation. Some of the yoga poses that can be practiced for respiratory issues like TB, asthma; COPD, bronchitis etc are Dhanurasna, Bhujangasana, Matsyasana and Trikonasana. These poses are very effective in lung cleansing and strengthening chest muscles. If one is practicing a layered asana such as Surya Namsakar, it has major detoxifying effects on our internal organs as well as brings about a sense of relaxation.

All of these practises, however, must be combined with healthy eating as part of our daily routine. Fresh vegetables, fruits, and pulses should be consumed on a daily basis and cooked with the appropriate spices for your body dosha type and season. Consuming local seasonal fruits and vegetables also boosts our immunity and helps us fight disease more effectively. While all of this may sound like general advice, our lungs will not be strong on their own unless our overall health is good.

Breathing is the first thing we do instinctively after birth, but when we are confronted with respiratory diseases, that instinct becomes a laborious task. Let us work together to make this activity as simple as possible by utilising alternative therapies.

No solution for pollution? Know these key enablers of healthy lungs

Incidentally, in the past, many of these Ayurvedic drugs were part of grandmother’s vast repertoire of home remedies that fortified households against various ailments, the publication pointed out

With so many Indian cities reported to have high levels of air pollution, the importance of lung hygiene cannot be understated. Lung hygiene is the best defence that the body can put up against air pollution, especially during winters, and ayurveda has a bunch of remedies to enable it.

The New Delhi-based Central Council for Research in Ayurvedic Sciences, reports, lists tulsi, neem and turmeric as key enablers of healthy lungs.

Ayurveda details about various plants and measures in combating environmental impurities and sanitizing the environment.

The ubiquitous and sacred Tulsi (Ocimum tenuiflorum L.) plays a vital role in absorbing pollutants, according to CCRAS. Neem (Azadirachta indica A.Juss.) leaves boiled in water have detoxification properties beneficial for skin and hair.

Turmeric has an anti-inflammatory property that protects lungs from the toxic effects of pollutants. Haritaki (Terminalia chebula Retz.) and ginger (Zingiber officinale Roscoe) too are beneficial for respiratory ailments.

Triphala taken with honey reinforces immunity, restoring balance to the system. The herb Pippali (Piper longum L.), with honey, purifies lungs and facilitates easy breathing, according to a paper by CCRAS.

Likewise, the smoke emitted from burning drugs like Laksha (Laccifer lacca), Haridra (Curcma longa L.), Ativisha (Aconitum heterophyllum Wall) and Haritaki is known to purify toxic air.

Shobhanjan mooladi agad may be used for treating those affected by such pollution, recommends CCRAS.

Incidentally, in the past, many of these Ayurvedic drugs were part of grandmother’s vast repertoire of home remedies that fortified households against various ailments, the publication pointed out.

Your lungs are constantly working to provide your body with all the oxygen it needs to function well. The respiratory system is vital for you to live. However, just like all other systems of our body, even the respiratory system is prone to wear and tear, more so due to high levels of toxins and pollutants in the air, says Dr Anil Shukla, Professor of Ayurveda at Mansarovar Ayurved Medical college, Bhopal.

Lung health also varies from season to season. In Ayurvedic context, when too much Vata (space +air) accumulates in the lungs we experience breathlessness, dry coughs, asthma, hoarseness of the voice, weak voice, pain when breathing and even lung allergies. If you are experiencing any of these, your lung health might be out of balance.

Ayurveda has effective remedies to bring an agitated dosha back into balance through diet, lifestyle and herb concoctions. To ensure the health of our lungs, let’s dive into ancient wisdom that’s highly effective even today, adds Dr Shukla.

STUDY: Omicron less dangerous than Delta?

Fused cells are often seen in respiratory tissues taken following severe disease…reports Asian Lite News.

The Omicron variant of Covid-19 may be significantly better than previous variants at evading vaccine-induced antibodies, but preliminary evidence also suggests that it is less likely to cause severe illness in the lungs compared to Delta.

In a yet-to-be peer-reviewed study, a team of researchers led by Indian-origin Professor Ravi Gupta from the University of Cambridge, created synthetic viruses – known as ‘pseudoviruses’ — that carried key mutations found in the Delta and Omicron strains — to study the virus’s behaviour.

The pseudoviruses were used to infect cells in lung organoids – ‘mini-lungs’ that model parts of the lung.

Despite having three mutations that were predicted to favour the spike cleavage, the researchers found the Omicron spike protein to be less efficient than the Delta spike at cleaving the ACE2 receptor and entering the lung cells.

In addition, once Omicron had entered the cells, it was also less able than Delta to cause fusion between cells – a phenomenon associated with impaired cell-to-cell spread. Fused cells are often seen in respiratory tissues taken following severe disease.

Indeed, when the team used a live Omicron virus and compared it to Delta in a spreading infection experiment using lung cells, Omicron was significantly poorer in replication, confirming the findings regarding impaired entry.

“We speculate that the more efficient the virus is at infecting our cells, the more severe the disease might be. The fact that Omicron is not so good at entering lung cells and that it causes fewer fused cells with lower infection levels in the lab suggests this new variant may cause less severe lung-associated disease,” said Gupta from the varsity’s Cambridge Institute of Therapeutic Immunology and Infectious Disease.

The team also tested the pseudoviruses against blood samples from vaccinated individuals who had received two doses of either the AstraZeneca (ChAdOx-1) or Pfizer (BNT162b2) vaccines.

On average, Omicron required around a 10-fold increase in the concentration of serum antibodies in order to neutralise the virus, compared to Delta. Of particular concern, antibodies from the majority of individuals who had received two doses of the AstraZeneca vaccine were unable to neutralise the virus. The data were confirmed in live virus experiments.

“The Omicron variant appears to be much better than Delta at evading neutralising antibodies in individuals who have received just two doses of the vaccine. A third dose ‘booster’ with the Pfizer vaccine was able to overturn this in the short term, though we’d still expect a waning in immunity to occur over time,” Gupta said.

He added that further work is needed to corroborate the findings. However, Gupta also urged caution.

“Omicron still represents a major public health challenge. Individuals who have only received two doses of the vaccine – or worse, none at all – are still at significant risk of Covid-19, and some will develop severe disease. The sheer number of new cases we are seeing every day reinforces the need for everyone to get their boosters as quickly as possible.”
