Delhi Air Pollution Is Damaging Your Heart: How To Protect It

Pollution and heart health

Quality of air in <span>Delhi</span> continues to be in the red zone with AQI reported at over 330 in most parts of the national capital and nearby regions. The plunge came as the government rushed to impose precautionary measures against the upcoming winter season and resulting smog. "Winter is coming and the level of <span>air pollution</span> is increasing,"Delhi Environment Minister Gopal Rai announced. 

<h2>How Does It Affect Your Heart?</h2> Harvard Health describes pollution as anything that is introduced into the environment by humans and that harms health and the ecosystem. Its subtype, air pollution, encompasses burning of fossil fuels (coal, gas, oil) and wildfires, that release toxic gasses in the environment. Indoor, air pollution, on the contrary, involves burning fireplaces and home cookstoves that use gas, coal and biomass fuels. 

Air pollution has a massive impact on your cardiovascular health. Particulate matter, particularly PM2.5, is a key factor in air pollution-related mortality, contributing to over 57% of global deaths from cardiovascular issues. These tiny particles, can spill into your bloodstream, through the air that goes into your lungs, and lead to the majority of cardiovascular diseases. In some cases, where the exposure is short-term, it could lead to risk of arrhythmias, heart attacks, and even strokes. Long-term exposure to these toxic particulate matter can lead to plaque buildup in the arteries and increase the risk of heart disease.

<h2 style="margin-bottom: 0.7em; line-height: 1.3; color: rgb(0, 0, 0); font-size: 24px; background: 0px 0px; text-rendering: optimizelegibility;">Here Is How You Can Safeguard Your Health</h2>Start by checking daily air pollution forecasts in your area. The colour-coded forecasts and air quality index (AQI) can let you know when the air is unhealthy in your community.

One of the major precautions is to limit particulate when AQI exceeds 200. Stop all forms of outdoor exercising including walking, jogging or cycling, when pollution levels are high. Furthermore, limit the amount of time your child spends playing outdoors if the air quality is unhealthy. 

Protect your indoor air quality too. There are various air purifiers that you can use at your home. Keep your windows closed on days when the pollution levels are high.

Encourage your child's school to reduce exposure to school bus emissions. To keep exhaust levels down, schools should not allow school buses to idle outside of their buildings.

Walk, bike or carpool. Use public transport such as buses, subways, light rail systems, commuter trains or other alternatives to driving your car. Delhi government has already the Odd-Even system in place under its pollution control measures. Under this system, cars with odd and even number plates are allowed on alternate days of the week.

Wear face masks when going out of the house. This will protect you from the toxic pollutants suspended in the air.

Don't burn wood or trash. Burning firewood and trash are among the major sources of particle pollution in many parts of the country.

Raise your voice. We can all take steps to reduce pollution and avoid exposure, but we need our policymakers at every level of government to prioritize clean air. Get involved by checking out our Healthy Air Campaign, where you can send messages to decision-makers and share your story.

10 Things About The New COVID-19 Vaccine Plan By Trump Administration

10 things about the new covid-19 vaccine plan by trump administration

A nine-month-old baby boy from Hoskote in Bengaluru Rural district has tested positive for <span>Covid-19</span>, according to Karnataka’s Health and Family Welfare Department. The infant was initially taken to a private hospital but later transferred to Vani Vilas Hospital in Kalasipalya, Bengaluru, for specialized care.

The child tested positive through a Rapid Antigen Test conducted on May 22. Officials confirmed that the baby is in stable condition and under close medical observation. Doctors at the hospital say he is responding well to treatment.

The case comes at a time when Karnataka is witnessing a slight but noticeable increase in Covid-19 cases. As of now, the state has 35 active infections, with 32 of them reported in Bengaluru alone. So far, no fatalities have been linked to the recent surge.

Health authorities noted a gradual uptick in cases over the last 20 days, prompting reminders to the public to follow <span>Covid</span> safety protocols. People have been advised to wear masks in crowded places, maintain hygiene, and avoid unnecessary gatherings—particularly in cities like Bengaluru, where the majority of cases are being reported.

Neighbouring Kerala has experienced a sharper rise in infections this month, with 182 confirmed cases so far. The state’s Health Minister has urged residents to remain alert and take precautionary measures. Among the districts, Kottayam has recorded the highest number of infections (57), followed by Ernakulam (34) and Thiruvananthapuram (30).

In response, Kerala’s health authorities have stepped up public messaging to promote early testing and isolation to limit the spread of the virus.

<h4>Andhra Pradesh Issues Public Advisory</h4>

In Andhra Pradesh, the Health Department released a public advisory on May 22 following indications of a rise in Covid-19 cases. Although specific figures have not been released, officials have recommended that people stay cautious, get tested if they show symptoms, and continue following preventive practices such as masking and hand hygiene.

In an internal order, Delhi’s health department directed all hospitals to ensure critical equipment like ventilators, BiPAP machines, and oxygen concentrators are functional. Staff are being asked to undergo refresher training, and all hospitals must report Influenza-like Illness (ILI) and Severe Acute Respiratory Illness (SARI) cases daily on the Integrated Health Information Platform (IHIP).

Additionally, 5% of ILI cases and 100% of SARI cases must undergo COVID-19 testing, in accordance with ICMR guidelines. Positive samples are to be sent to Lok Nayak Hospital for genome sequencing to detect any emerging variants.

<h4>Cases Originally From Singapore And Hong Kong</h4>

Singapore and Hong Kong are witnessing a noticeable surge in COVID-19 cases, primarily driven by LF.7 and NB.1.8 sub-variants. Singapore’s Ministry of Health has urged citizens to get vaccinated, especially those who haven’t received their initial doses. Hong Kong has reached its highest case numbers in over a year and is encouraging mask-wearing and crowd avoidance.

Unlike earlier variants, the current wave presents some slightly different symptoms. While cough and sore throat remain common, additional symptoms include nausea, vomiting, brain fog, and conjunctivitis. Most cases are mild, but health authorities advise individuals to monitor symptoms and seek medical attention if needed.

New Delhi is witnessing a modest increase in <span>COVID-19</span> cases, with 23 active infections reported as of May 22, Health Minister Dr. Pankaj Singh confirmed on Friday. Emphasizing that there is no reason to panic, Singh said all patients are currently stable. “Two to three patients are admitted to private hospitals while the others are being monitored. We will verify if these patients are residents of Delhi or from outside. The strain is similar to influenza,” he noted.

The minister also reassured the public about the state’s preparedness. “We’ve had conversations with medical superintendents. Eight senior officials are visiting hospitals daily to ensure everything is in order. Our hospitals are equipped with oxygen, oximeters, and essential medical supplies,” Singh added.

In line with this, the Delhi health department has instructed all private and government hospitals to ensure the availability of beds, oxygen, essential medicines, and vaccines. An advisory will be issued shortly to provide further guidance.

<h4>Omicron Sub-Variants Fuel Regional and Global Spike</h4>

The rise in COVID-19 cases in Delhi and other Indian states comes after a spike was observed in several Asian countries. Health authorities have attributed the increase to Omicron-related sub-variants—primarily LF.7 and NB.1.8—descendants of the JN.1 variant, which in turn evolved from the BA.2.86 (Pirola) strain.

These sub-lineages are known for their high transmissibility but relatively mild symptoms. Despite the rise, experts maintain that the current wave is manageable and no immediate threat of severe disease has been identified.

<h4>Neighboring States And Others Also Report Mild Cases</h4>

Haryana: Two mild COVID-19 cases were reported in Gurgaon—a 62-year-old man and a 31-year-old woman who had recently travelled from Mumbai. Both are in home isolation. Meanwhile, a 28-year-old security guard from Faridabad tested positive at Delhi’s Safdarjung Hospital. None had a travel history abroad or known contact with infected persons. Health officials emphasized that these are isolated, mild cases and do not indicate a severe outbreak.

Maharashtra: The state has reported 95 new COVID-19 cases in Mumbai this month, with a total of 106 since January. At least 16 patients are hospitalized, mostly shifted to Seven Hills Hospital from KEM Hospital. Pune, although not reporting any active cases currently, has reserved 50 beds at Naidu Hospital as a precautionary step.

<strong>Tamil Nadu:</strong> In Chennai and Puducherry, health officials are seeing a shift in viral diagnosis, where fevers initially linked to influenza are now being identified as COVID-19. Public Health Director Dr. TS Selvavinayagam has urged caution in crowded places but reassured the public not to panic.

<strong>Karnataka: </strong>The state currently has 16 active COVID-19 cases, confirmed by Health Minister Dinesh Gundu Rao.

<strong>Gujarat: </strong>Seven new cases were reported in Ahmedabad in a single day—a sharp spike for a city that has averaged one case per month over the past year. All patients are in home isolation, and their samples have been sent for genomic sequencing. Officials say the infections are from the JN.1 variant and are mild in nature.

FDA Greenlights Nucala as New Treatment for COPD

FDA approves Nucala as add-on therapy for COPD with high eosinophils, offering new hope by reducing flare-ups in patients unresponsive to inhaled treatments.

The U.S. Food and Drug Administration (FDA) has approved Nucala (mepolizumab) as an add-on maintenance treatment for adults with chronic obstructive pulmonary disease (<span>COPD</span>) that remains inadequately controlled despite existing therapies. The approval offers new hope to patients whose symptoms persist despite being on inhaled triple therapy.

According to the World Health Organization (WHO), COPD is a common, preventable, and treatable disease that is characterized by persistent respiratory symptoms and airflow limitation due to airway and/or alveolar abnormalities. It typically results from significant exposure to noxious particles or gases.

<ul><li>Chronic cough</li><li>Shortness of breath</li><li>Wheezing</li><li>Chest tightness</li><li>Excess mucus production</li></ul>

Causes of COPD range from long-term smoking and air pollution exposure to occupational dusts and fumes. Genetics and respiratory infections in early life can also contribute.

COPD is progressive and often worsens over time, severely impacting quality of life. One of the most critical challenges in managing the condition is reducing exacerbations—flare-ups that may require hospitalization or emergency treatment.

Nucala is the only approved biologic that has been specifically studied in COPD patients with an eosinophilic phenotype defined by a blood eosinophil count (BEC) of ≥150 cells/μL. This is important because up to 70% of U.S. COPD patients who are not adequately managed on inhaled triple therapy fall into this category.

Biologics like Nucala work by targeting specific pathways in the immune system. Mepolizumab, the active ingredient in Nucala, is an anti-IL-5 monoclonal antibody that reduces eosinophilic inflammation—a key contributor to COPD exacerbations in certain patients.

The FDA’s approval of Nucala is based on results from two large Phase 3 clinical trials, MATINEE and METREX, which evaluated its use alongside optimal inhaled therapy. Both were randomized, double-blind, and placebo-controlled.

In the MATINEE trial, involving 804 patients with a BEC ≥300 cells/μL, Nucala showed:

A significant reduction in moderate or severe exacerbations: 0.80 vs 1.01 events/year (rate ratio, 0.79).

A 35% decrease in emergency visits or hospitalizations for COPD exacerbations (rate ratio, 0.65).

The METREX trial produced similar outcomes. Patients on Nucala had:

Fewer moderate or severe exacerbations: 1.40 vs 1.71 events/year (rate ratio, 0.82).

Adverse events were comparable between the Nucala and placebo groups, suggesting a favorable safety profile.

“COPD isn't just a disease, it's a relentless cycle,” said Dr. Jean Wright, CEO of the COPD Foundation. “Even with current therapies, managing exacerbations remains a daily battle. Biologics like mepolizumab offer new hope.”

The FDA approval was granted to GSK, the pharmaceutical company that developed Nucala. With this decision, clinicians now have a novel option for patients with eosinophilic COPD who are still struggling despite standard treatment.
