Dense, toxic smog covered India’s capital on Monday, driving air pollution to its highest levels in weeks, disrupting travel, and prompting authorities to enforce the strictest containment measures. More than 40 flights were cancelled, with several dozen more delayed. Over 50 trains arriving and departing from New Delhi faced delays of several hours, officials reported. Healthcare experts urged residents to stay indoors as hospitals recorded a surge in patients with breathing problems and irritated eyes. Now, a pulmonologist is warning that indoor air in Delhi might actually be more hazardous than the smog outdoors.

Delhi Pollution: Indoor Air More Toxic Than Outdoor Smog

Indoor air quality in Delhi is reportedly worse than the air outside, according to a lung specialist. Dr. Vivek Nangia, head of pulmonology at Max Healthcare, said indoor spaces can have particulate matter, or PM2.5 levels, nearly two-and-a-half times higher than outdoor readings, even when there are no direct pollution sources indoors.

“Indoor air can be 20 to 30 times more polluted than outdoor air, so it’s important to monitor and improve it,” he explained. Studies have shown that lung-damaging tiny particles inside homes are “substantially higher” than what nearby government monitors report outdoors. This was also confirmed by a study conducted by the Energy Policy Institute at the University of Chicago (EPIC) between 2018 and 2020, which surveyed thousands of Delhi households across different income levels, finding that both rich and poor families are affected equally.

Researchers noted that wealthier households were 13 times more likely to own air purifiers than low-income ones, yet indoor pollution in those homes was only about 10% lower than in disadvantaged settings.

“In Delhi, the bottom line is—whether someone is rich or poor, nobody gets to breathe clean air,” said Dr. Kenneth Lee, the study’s lead author. “It’s a complex, vicious cycle.”

How Does Indoor Air Quality Affect Your Lungs?

Poor indoor air quality (IAQ) can harm the lungs by causing inflammation, weakening the body’s defenses, and triggering or worsening conditions such as asthma and COPD. Pollutants like dust, mold, VOCs, and smoke can lead to coughing, wheezing, infections, and long-term lung damage, even raising the risk of lung cancer over time. Because the lungs are constantly exposed to air, they are extremely sensitive to irritants, which can reduce lung function and capacity—particularly in children, older adults, and those with pre-existing conditions, according to the American Lung Association.

Dr. Nangia noted that patients are now showing a different kind of chest congestion. “These days we’re seeing two kinds of patients—those who never had lung issues before but are now coming in, saying their coughs, sneezing, and chest congestion started once air quality worsened, and those with existing lung problems who are experiencing much worse symptoms,” he said.

How To Protect Yourself From Indoor Toxic Air?

According to the American Lung Association, protecting yourself from indoor air pollution involves controlling sources of pollutants (no smoking, using low-VOC products), improving ventilation (opening windows, using exhaust fans), using HEPA air purifiers, cleaning regularly (dusting and vacuuming), managing humidity to prevent mold, and wearing N95 masks on days with high outdoor pollution to reduce indoor air infiltration.

Why Autism In Women Is Often Overlooked And Misdiagnosed

Updated Apr 2, 2026 | 06:30 PM IST

SummarySubtle presentation, masking behaviors, gender bias, and overlap with other conditions cause the overlooking of autism in women. Clinicians and the general public need to be more aware of autism in women for timely diagnosis and necessary support.

Autism in women is not often entirely recognized because this disorder does not always have to correspond to the “classic” picture characteristic of males.

The diagnosis is based on a male criterion with such behavior as obvious withdrawal from a group, overtly displayed repetitive behaviour, and limited interests. There can be mild social deficit or internalized anger and frustration that can pass unnoticed in clinical practice.

The Art of Masking

One of the most significant reasons behind underdiagnosis is masking (also called camouflaging). Masking is one of the most significant reasons for underdiagnosis. This is helpful in masking but also covers or conceals essential symptoms.

Masking causes mental exhaustion, anxiety, and burnout, but it does not address the underlying autism and leaves it undiagnosed.

Stereotypes And Gender Bias

There is a strong societal stereotype that autism is a “male condition”. This bias is felt by parents, teachers, as well as health care professionals.

Sex bias is evident in that boys get referred for evaluation early. Girls are often tagged “shy,” “sensitive,” and “introverted.”

Their struggles are normalized instead of being explored for any issues. Gender bias is a significant contributor to delayed or wrong diagnosis.

Different Interests, Less Suspicion

A restricted interest is another hallmark of autism, but in women, it tends to be more socially acceptable. Their interests conform to the norms of society; they do not predispose clinical suspicion as opposed to more masculine interests like mechanical systems or numbers.

Overlap With Other Conditions

Autism in women being misdiagnosed as other psychiatric disorders is due to symptom comorbidity. Some of the common misdiagnoses are:

  • anxiety disorders,
  • major depressive disorder,
  • borderline personality disorder,
  • eating disorders.

In many cases, these are secondary to autism as a result of years of living with undiagnosed autism.

Social Expectations And Conditioning

From an early age, girls are often conditioned to be socially attentive, empathetic, and compliant. This societal conditioning pushes autistic girls to adapt and hide their difficulties.

These may include forcing themselves into socializing. Fitting in is deemed more important than comfort. They end up creating coping mechanisms that mask their difficulties.

While this may benefit outward functioning, it postpones the recognition of underlying neurodevelopmental differences.

The Consequences of Late Diagnosis

Delayed diagnosis or missed diagnosis has the following effects:

  • Chronic mental illness
  • Low self-esteem
  • Confusion about identity
  • Inadequate support services
However, a correct diagnosis, even if received in adulthood, can be transformative, offering clarity, validation, and access to appropriate interventions.

Endometriosis Taught Me To Always Listen To My Body, Says Model Padma Lakshmi

Updated Apr 2, 2026 | 05:00 PM IST

SummaryThe 55-year-old, Co-founder of Endometriosis Foundation of America, said that the condition made her understand how strong she is and called for greater awareness and self-advocacy among women.

The World Health Organization estimates that 10 percent (190 million) of reproductive-age women worldwide suffer from endometriosis.

The chronic and complex menstrual disease that affects many women is characterized by severe pain during menstruation, heavy menstrual bleeding, chronic pelvic pain (pain that does not go away when the menstrual cycle ends), infertility, and abdominal bloating and nausea.

The incurable condition poses a significant challenge to women as it affects their personal and professional lives, relationships, and fertility, among others, due to persistent pain and fatigue.

The diagnosis also gets delayed, as endometriosis is often confused with PCOS, or Polycystic Ovary Syndrome, due to some overlapping symptoms like irregular menstrual periods. The symptoms may continue to persist or recur after treatment is initiated.

In a powerful statement resonating with millions worldwide, Indian American author and television host Padma Lakshmi has shared her experience with the condition.

Opening about her personal battle with endometriosis, the 55-year-old, Co-founder of Endometriosis Foundation of America, said that the condition made her understand how strong she is and called for greater awareness and self-advocacy among women.

"Endometriosis has taught me that I should always listen to my body. Pain is your body's way of telling you something is wrong,” said Lakshmi, in a media post on social media platform Instagram.

"Through my struggles with endometriosis, I've learned that, actually, I have a very high threshold for pain, that I may be stronger than I know, but that I shouldn't always need to be,” PopSugar quoted her as saying.

Lakshmi noted that it is now her life's mission "to advocate for my own health, and also to advocate for all women with endometriosis."

What Is Endometriosis?

Endometriosis happens when tissue similar to the lining of the uterus grows outside the uterus. These tissues commonly develop on the ovaries, fallopian tubes, or the pelvic lining.

Endometriosis affects many women and can impact their daily lives, including their ability to work comfortably. Many women continue their professional responsibilities despite experiencing severe discomfort, fatigue, and pain.

Raising awareness about the condition and encouraging supportive workplaces can help women manage both their health and career more effectively.

Since it is a progressive disorder, timely intervention remains key to managing it. In many cases, women live with symptoms for several years before receiving the correct diagnosis, which can delay treatment and affect their quality of life.

Treating Endometriosis

Treatment is particularly based on the severity of symptoms. Women will be advised lifestyle modifications such as regular exercise, stress management, and an anti-inflammatory diet. Non-steroidal anti-inflammatory drugs may help reduce discomfort.

Hormonal therapies may also be used to control symptoms. Some women will be advised to undergo laparoscopy to remove endometriotic cysts.

Minimally invasive surgery can help remove lesions and restore pelvic anatomy, which may also improve fertility in some cases. In advanced cases, surgery can be recommended to women.

What Is Herpes?

The herpes simplex virus (HSV) is very common, and the infection is lifelong. But the symptoms can come and go over different periods of life. Many people never get any symptoms linked to their infection.

The common virus, carried by up to 50 to 80 percent of adults, can cause painful blisters or ulcers. It primarily spreads by skin-to-skin contact. It is treatable but not curable.

There are two types of herpes simplex virus: HSV-1 and HSV-2.

HSV- 1 is the most common and usually spreads by oral contact. It causes infections in or around the mouth (such as oral herpes or cold sores), as well as genital herpes.

Common oral herpes symptoms include

  • blisters (cold sores)
  • open sores (ulcers) in or around the mouth or lips.

HSV-2 generally spreads by sexual contact and causes genital herpes.

Its symptoms include painful

  • bumps,
  • blisters,
  • open sores (ulcers) around the genitals or anus.

How Makeup Testers Can Spread Infection

Experts warned that makeup testers can become a breeding ground for germs. The repeated use of the open samples can spur their growth and can then spread by “double-dipping” — reusing an applicator after touching the skin. This can transfer viruses and bacteria between users.

“You can absolutely get a herpes infection from a makeup tester," Dr. Whitney Bowe, a dermatologist in New York City, told TODAY. "The more ‘double dipping’ that occurs, the higher the chance of spreading viruses or bacteria at a makeup counter.”

A 2010 study by researchers from Rowan University in New Jersey found that cosmetic samples harbored strep, E.coli, and staph.

For two years, the team examined makeup testers at makeup counters, specialty stores, and drug stores. They found that Saturday is the busiest day of the week, and 100 percent of the samples carried some sort of germ.

How To Stay Safe?

To reduce the risk of infection, experts recommend:

  • Much like the toothbrush, personal cosmetics and cosmetic brushes must not be shared.
  • Wash and dry your brushes regularly to avoid bacterial growth.
  • Avoid applying testers directly to your lips or skin
  • Use disposable applicators
  • Test products on your hand rather than your face
  • Avoid using testers if you have cuts, chapped lips, or active infections.
