Marking his 59th birthday on Saturday, bollywood megastar Shah Rukh Khan revealed that he has quit smoking. Khan, who had once admitted to smoking 100 cigarettes a day, said that he doesn't feel much but breathless after his new lifestyle change. "Mujhe lga tha ki I will not feel breathless, but abhi woh bhi feel kar raha hoon. Inshallah, woh bhi theek ho jayega. (I thought I wouldn't feel breathless after quitting smoking, but I still do. That too will be okay)
One of the primary reasons that Khan is feeling breathless is because his body is healing. Immediately as a person stops smoking tobacco or any other substance, their respiratory system begins healing. Smoking primarily hurts the cilia, which are tiny hair-like structures within the lungs, responsible for removing mucus and toxins. This cilia becomes active once smoking is stopped, cleaning out tar and mucus deposited during the smoking period. This cleaning process may result in a feeling of breathlessness.
Another factor is nicotine withdrawal. Nicotine stimulates the central nervous system, which includes slightly increasing heart rate and breathing efficiency. When the body goes into withdrawal from this substance, then the person shows symptoms such as shortness of breath, racing heart and anxiety.
The altering of gasses in the respiratory tract also plays a crucial role. After a person quits smoking, carbon monoxide in the blood reduces and oxygen levels rise. This increase may trigger inefficiency in breathing and a change in blood gas levels may manifest itself in temporary shortness of breath.
Moreover, smoking harms the lungs, leading to chronic obstructive pulmonary disease (COPD) and lung cancer. The toxic chemicals in cigarettes also impair the immune system, making smokers more susceptible to infections. Additionally, research indicates that smoking can accelerate ageing, resulting in skin damage and premature wrinkles.
The study emphasizes that quitting smoking can significantly improve health outcomes, with benefits observed shortly after cessation. As awareness grows about the dangers of smoking, it’s crucial to understand its extensive effects on overall health and well-being.

Tooth disorders led to an average of nearly 1.94 million emergency department (ED) visits each year between 2020 and 2022, according to a recent data brief by the National Center for Health Statistics. The data, drawn from the National Hospital Ambulatory Medical Care Survey, highlights a significant burden on emergency care systems across the United States.
The analysis, led by Susan M. Schappert and Dr. Loredana Santo, revealed that adults aged 25 to 34 accounted for the highest proportion of these emergency visits—29.2 percent. While tooth disorders represented 1.4 percent of all ED visits, that translated to about 59.4 visits per 10,000 people annually.
When broken down by race and ethnicity, White non-Hispanic individuals made up the largest share, followed by Black non-Hispanics and Hispanics. Medicaid was noted as the primary expected source of payment, suggesting that many patients with limited access to dental care rely on emergency services for dental issues.
Another notable trend: the prescription of opioids for dental pain relief has dropped significantly. From 2014 to 2016, 38.1 percent of patients were prescribed opioids as the sole form of pain relief. By 2020 to 2022, that figure had fallen to 16.5 percent, indicating a shift in pain management strategies amid growing awareness of the opioid crisis.
Tooth disorders include a range of conditions that affect the teeth, such as:
Tooth disorders can be caused by various factors, including:
Different tooth problems come with different symptoms, but common warning signs include:
Dentists typically diagnose tooth disorders through a physical examination, using dental instruments and sometimes X-rays. Depending on the issue, treatments may include:
Yes—most tooth disorders are preventable with good oral hygiene. Experts recommend:
Dental care often gets sidelined, especially for those with limited access to regular services. Yet, as the numbers show, ignoring tooth problems can lead to costly emergency visits and long-term health risks. Promoting awareness and access to preventive care is key to reducing this burden—not just on individuals, but on emergency care systems too.

Deaths due to alcohol-associated liver disease (ALD) are climbing at an alarming rate across the United States, with certain groups being disproportionately affected. A new study published on June 11 in JAMA Network Open found that ALD-related deaths rose nearly 9% each year between 2018 and 2022—more than double the rate of increase seen from 2006 to 2018.
Experts believe this sharp uptick is partly linked to increased alcohol consumption during the COVID-19 pandemic. Other contributing factors include chronic conditions like obesity and hypertension, which can worsen liver health. “It puts numbers to what we’re seeing in the hospital, in the clinic,” said Dr. Brian Lee, a liver specialist at Keck Medicine of USC, in a report to STAT News.
While men still experience more deaths from ALD—17 per 100,000 in 2022—women’s death rates have risen more sharply. In 2022, 8 out of every 100,000 women died from alcohol-related liver disease, a significant jump from 3 per 100,000 at the beginning of the study period. Women’s mortality rate grew at approximately 4.3% per year—almost twice the rate seen in men.
The study also revealed a devastating impact on Indigenous communities. American Indian and Alaska Native adults had the highest cirrhosis death rate in 2022, at 33 per 100,000 people. Additionally, alcohol-associated hepatitis deaths in these groups more than doubled between 2010 and 2022.
Dr. Nasim Maleki, a psychiatry professor at Harvard Medical School, noted that although the pandemic has eased, its long-term effects—particularly in marginalized communities—are still unfolding. “The pandemic itself came under control, but the disparities that came with it continued and lingered,” she said.
A particularly troubling trend is the increase in alcohol-associated hepatitis deaths among people aged 25 to 44. This condition can develop quickly and is marked by symptoms like fatigue, jaundice, and liver pain—even in individuals who haven't been heavy drinkers for long.
Liver experts warn that the worst effects of pandemic-related drinking might still be ahead. “Alcohol-related cirrhosis takes time to develop. So we may not see the true extent of the consequences until five, probably 10, years from now, which is very concerning,” said Dr. Robert Wong of Stanford University.
One reason for the sharper rise among women lies in biology. Cisgender women metabolize alcohol differently than cisgender men, which means their organs may suffer more damage from lower levels of alcohol consumption over time. That’s why current federal guidelines recommend no more than one alcoholic drink per day for women, compared to two for men.
“You’d be surprised by how shocked people are when they hear that drinking more than two drinks per day is considered heavy drinking by federal definitions,” Dr. Lee added.
In 2021, over 12,000 deaths from “unspecified liver cirrhosis” were linked to excessive drinking, although that may not always be evident from death certificates. Marissa Esser, who previously led the alcohol program at the U.S. Centers for Disease Control and Prevention, highlighted this hidden toll before the program was disbanded earlier this year.
The American Medical Association is now calling for more public education on alcohol’s risks, including its link to breast cancer. It is also urging clearer labeling on alcoholic beverages to help consumers make informed choices.
Though some data suggests a slight drop in alcohol use since its peak in 2020, it remains uncertain whether this will reduce deaths in the coming years. For now, ALD continues to be the leading reason for liver transplants in the U.S., and alcohol-associated hepatitis is the fastest-growing cause.

As the summer sun rises high, everyone anticipates relief from seasonal sniffles. Yet increasingly, more and more people are falling ill with cold-like symptoms in warmer weather too. The twist? A new Covid strain—NB.1.8.1—is spreading low-key around the world, from Asia to America and the UK. The challenge is distinguishing between a run-of-the-mill summer cold and a COVID-19 infection.
Typically, respiratory illnesses peak in the colder months when more time is spent indoors and dry air allows viruses to be more easily susceptible. Summer, however, is not virus-free. Parainfluenza virus Type 3, enteroviruses, adenoviruses, and even rhinoviruses are still causing issues in warmer climates. Social events, travel, lack of rest, more alcohol consumption, and air conditioning all set the stage for infections.
Complicating the situation further this summer is the discovery of the NB.1.8.1 Covid strain. Although the World Health Organization (WHO) only recently started monitoring it, scientists are closely monitoring its trajectory and possible implications.
Initially discovered in China in January 2025, NB.1.8.1 has a number of mutations that have caught the eye of the world's health authorities. The good news? There is as yet no evidence to suggest it results in more serious disease. In fact, U.K. Health Security Agency statistics indicate a modest rise in COVID cases with 5.2% of patients positive—up from 4.5% last week.
To date, just 13 of the confirmed NB.1.8.1 cases in the U.K. have been sequenced, the majority of them in April and May. While uncommon at present, the fact that it shares features with other variants of Covid means caution is still crucial.
Both summer colds and Covid-19 have common symptoms such as:
However some symptoms will tend more towards Covid, such as:
There is no guaranteed way to tell the difference between a summer cold and Covid without doing a diagnostic test. Mild COVID-19 symptoms are easily mistaken for other seasonal viruses.
Colds—seasonal or not—are viral illnesses that are transmitted by respiratory droplets, fomites (contaminated surfaces), or close proximity. The main culprits are rhinoviruses, especially during the winter months, but the warmer months experience an upsurge in viruses such as parainfluenza, enteroviruses (coxsackie and echovirus), and adenoviruses.
Summer activities—weddings, concerts, holidays—promote intimate contact between groups, and typical summer behaviors such as drinking, bad sleep, and poor diet compromise immune systems. Air conditioning units, by dehydrating nasal passages, also impair the body's resistance to viral invaders.
The Centers for Disease Control and Prevention (CDC) urges anyone with cold-like symptoms to monitor closely. Covid-19 symptoms can appear two to 14 days after exposure and vary from mild to severe. The virus can be contagious two days before symptoms emerge and up to 10 days—or more—in immunocompromised individuals.
If you’re feeling unwell, the best course of action is to:
Timely treatment, such as antiviral therapy with Paxlovid, is ensured through accurate diagnosis, particularly among high-risk individuals.
While a newer vaccine aimed at fall variants is being developed, the existing vaccines remain protective against NB.1.8.1. The variant is of the "drifter" type from the Omicron lineage, which indicates earlier immunity could still help prevent severe disease.
Dr. Aaron Chen, a Johns Hopkins University virologist, observes, "Although mutation is unavoidable, current vaccines remain effective in preventing hospitalization and complications from new variants, such as NB.1.8.1."
There's no surefire way to completely avoid viruses, unfortunately. But here are some practical tips from experts:
Most people recover from summer colds and mild Covid-19 at home. Supportive care—hydration, over-the-counter pain relief, and rest—is typically enough. Nasal decongestants and lozenges can ease symptoms, while more serious or persistent cases warrant medical consultation.
If you suspect Covid, getting tested is crucial—not only for your health but for the wellbeing of those around you.
