When something is going wrong in your body, there will be signs. They may be subtle, but they are visible in close observation. If you are a smoker, you may be worried about the smell of smoke emanating from your mouth or clothes. However, there are other signs that tell whether you smoke or not and these signs are difficult to get rid of!
Smoking is the harmful act of inhaling tobacco infused smoke and is a common activity all over the world. According to the Center of Disease Control and Prevention (CDC), over 480,000 deaths happen each year due to smoking or smoke inhalation. The organization explained that smoking causes harm to nearly all organs and quitting lowers the risk of early death and other smoking related diseases.
Like many other substances, there are clear tell-tale signs when someone is smoking. This is especially important for finding lung problems like Chronic obstructive pulmonary disease (COPD), which is a lung disease that makes it hard to breathe, sooner so people can get help.
Action on Smoking and Health (ASH) explains that tobacco smoke has more than 7,000 harmful chemicals like nicotine, carbon monoxide, and various metals like arsenic, cadmium, and lead, quickly reach your lungs and then travel through your blood to all your organs, including your skin. Smoking damages your skin's ability to heal because it increases an enzyme metalloproteinase (MMPs) that breaks down collagen. Collagen is what keeps your skin smooth and elastic. As you lose collagen, your skin sags. Squinting from the smoke and puckering your mouth when smoking also cause wrinkles around your eyes and mouth.
Smoking also reduces blood flow to your skin, which means it gets less oxygen and nutrients. All these things together lead to what doctors call a "smoker's face." Quitting smoking can help prevent or slow down these skin problems."
Here are some visible signs of smoking in people, according to 2013, Lung India
When people smoke, the tar and other chemicals in the smoke stick to their fingers and nails. This repeated contact causes a yellow stain that's hard to wash off. It's a very common sign that someone regularly handles cigarettes or biris.
Especially in older people with white moustaches, smoking causes a yellowing effect. This is most noticeable in the center of the moustache, where the smoke from the nose directly hits the hair. The consistent exposure to smoke colors the hair over time.
Heavy smokers often have a bluish-black tint to their lips. This discoloration happens because the chemicals in tobacco smoke affect the blood flow and the color of the skin on the lips. The constant exposure changes the lip's natural color.
Smoking causes teeth to stain both inside and out. The outside of the teeth turns yellow from the tar, while the inside develops a brownish-black stain. This happens because the smoke seeps into the enamel and discolors the teeth over time.
Smoking makes the skin age faster. This leads to wrinkles like "crow's feet" around the eyes and "cobblestone wrinkles" on the neck. This happens because smoking reduces blood flow, limiting oxygen to the skin, and damages collagen, which keeps skin elastic.
This condition, also known as "Favre–Racouchot syndrome," causes blackheads and wrinkles, especially around the eyes and temples. It is made worse by both sun exposure and heavy smoking. The skin becomes discolored with visible nodules and wrinkles.
A study published in Thorax 2006 found a connection between wrinkles on the face and COPD, a lung disease. It's thought that smoking affects both the skin and lungs through similar processes. If doctors notice signs like "crow's feet" on a smoker's face, they might recommend tests for COPD. This early detection can help people get treatment sooner and improve their lung health.
World Malaria Day: Avoid going outdoors in the evening without a mosquito repellant. (Photo credit: iStock)
Delhi-NCR witnessed unexpected showers in the city this year in the month of April. Before the heatwave could get as severe as it usually is every season, there were a few days where the national capital witnessed refreshing showers—but as it turns out, these showers often increase the risk of diseases like malaria. Yes, unexpected showers may bring temporary relief from heat, but they also quietly reset the risk for diseases like malaria. The concern today is not just rainfall, but how changing climate patterns are shifting the timeline of disease transmission—often weeks before the monsoon fully arrives.
Ahead of World Malaria Day, Dr Suranjit Chatterjee, Senior Consultant-Internal Medicine, Indraprastha Apollo Hospital, Delhi, spoke about the effects of such unexpected rains ahead of the monsoon season.
Malaria has long been seen as a monsoon-linked illness, but that pattern is changing. Intermittent rainfall, rising temperatures, and increased humidity are now creating ideal breeding conditions much earlier in the year. Even a short spell of rain can lead to water accumulation in urban areas—on terraces, construction sites, in clogged drains, and in poorly managed storage spaces. These become hidden breeding grounds for mosquitoes, accelerating their life cycle and increasing the risk of early transmission.
From a healthcare perspective, this shift is significant. The first fever after early showers is often overlooked or dismissed as a seasonal viral infection. However, malaria in its early stage can closely resemble common viral illnesses, presenting with symptoms such as fever, chills, headache, body ache, and fatigue. This overlap frequently delays diagnosis. Any fever that persists beyond 2–3 days, recurs, or does not respond to basic treatment should be tested promptly. Early detection remains critical to preventing complications.
Early malaria can look like a common viral fever. The symptoms of the disease are:
Waiting for the monsoon to begin preventive action is no longer effective. The response must start with the first signs of rain. Clearing drains, eliminating stagnant water, monitoring construction zones, and ensuring proper waste management are essential early steps. At the household level, covering water containers, maintaining clean terraces, and regular checks for water accumulation can significantly reduce risk. Some of the key precautions to take against malaria are the following:
A year-round public health priority
World Malaria Day serves as a reminder that malaria prevention is not seasonal—it is continuous. In an era of unpredictable weather patterns, cities and communities must adapt quickly. Acting only when cases begin to rise means reacting too late. The real shift lies in recognising that prevention must begin with the first unexpected shower, not the peak of the monsoon.

Urgent action is required to strengthen diagnostics and vaccines to address gaps in dengue treatment, public health experts said.
The experts, including scientists and policymakers, were speaking at a day-long dialogue hosted in New Delhi by the Drugs for Neglected Diseases initiative (DNDi) in collaboration with the Translational Health Science and Technology Institute (THSTI), the Ministry of Health and Family Welfare, and the WHO South-East Asia Region.
The convening assumes significance ahead of the monsoon season, which historically sees a rise in Aedes aegypti mosquito populations and dengue transmission across health systems in South and South-East Asia.
"The WHO South-East Asia Region alone accounts for more than half of the global dengue burden, with 1.3 billion people living at risk across 10 endemic countries," said Dr Catharina Boehme, Officer in charge, World Health Organization, South-East Asia Regional Office.
Dr. Boehme called the rising burden of dengue both an economic crisis and a social crisis. She noted that beyond health system costs, dengue often leads to "lost productivity, lost wages, lost futures".
"To change this trajectory, we must close the gap on diagnostics, on vaccines, on therapeutics, and on health system resilience," Dr. Boehme said.

India reported over 2.89 lakh dengue cases in 2023, though experts believe the actual burden could be significantly higher due to underreporting and surveillance gaps.
Taruna Madan Gupta, Scientist G and Head, Development Research Division, ICMR, called dengue an "unequivocally a national health priority for India."
Gupta noted that "India is advancing on multiple fronts—from strengthening public health systems to enabling public-private partnerships, including Phase III trials of an indigenous tetravalent dengue vaccine with over 10,000 participants, and regulatory progress on global vaccines".
However, the expert flagged a critical gap, which is "the absence of an effective therapeutic" for the mosquito-borne disease.
The experts noted that even though there are improvements in surveillance and scientific understanding, patients still lack access to specific treatment options.
“Addressing this gap requires sustained commitment from governments, funders, and partners," said Dr Sanjay Sarin, Continental Lead Asia and Director South Asia, DNDi.
Dengue fever is a viral disease transmitted by Aedes mosquitoes, which are most active during the daytime. Dengue fever typically has minor or no symptoms, but it can occasionally result in severe sickness, hospitalization, and even death.
Common Symptoms include:
It estimates that:
These vaccines are designed to protect against all four serotypes of the virus, with a focus on reducing severe disease and hospitalizations.

In today’s fast-paced, wellness-driven world, looking fit does not always translate to being reproductively healthy. Currently, even fit and active individuals are facing fertility challenges due to hidden hormonal and metabolic imbalances. Hence, it is necessary to focus on reproductive health. Dr. Meenu Handa, Director of Fertility & Head Academic of Reproductive Medicine, Motherhood Hospitals, Gurgaon, decoded the link and listed some of the common fertility issues that most people overlook.
Now, a large number of people are opting for various activities such as yoga, Zumba, Pilates, the gym, and kickboxing to stay fit. Those who are health-conscious are also maintaining an optimum weight with a proper diet. These habits, in turn, can help to ensure good fertility. Shockingly, many people who are perfectly fit and fine on the outside may also struggle with fertility problems. Yes, that is right! This is also a common occurrence nowadays. Couples are panicking as they seem to adhere to a well-balanced lifestyle but still fail to conceive. So, this can be referred to as “invisible fertility issues," where underlying hormonal or metabolic imbalances silently affect reproductive health.
Dr Handa said that many men and women who exercise regularly may suffer from issues such as hormone imbalance, fluctuating insulin levels, poor thyroid function, and compromised reproductive organ health. Conditions like polycystic ovary syndrome (PCOS), thyroid disorders, insulin resistance, and even chronic stress can exist without obvious physical signs and can take a toll on fertility. The expert also shared some of the common hidden infertility issues.
Even couples who are physically fit today often deal with high mental stress due to demanding jobs and poor work-life balance. This ongoing stress can quietly disturb hormonal balance in the body. Increased cortisol levels may affect ovulation in women and sperm production in men and, over time, can impact egg and sperm quality—making natural conception more difficult. That is why managing stress is just as important as staying physically fit when planning a pregnancy.
Women may have issues like poor ovulation, compromised egg quality, or hormonal imbalance, even if their menses tend to be regular. In some cases, even subtle symptoms like fatigue, acne, hair fall, or mood swings may be overlooked but can signal deeper hormonal concerns. Men can struggle with low sperm count, which can affect their fertility. Even insufficient sleep, excessive exercise, or extreme dieting can increase the chances of hormonal imbalance and fertility issues. It is necessary to consult an expert and seek timely help. Pollution and lifestyle stress also contribute to the trend.
Couples should not just plan a pregnancy because they are fit and exercise daily. Pregnancy should not rely only on outward fitness as a sign of reproductive health. Regular health check-ups, including hormone tests and fertility assessments, can help identify hidden issues early.
So, awareness, balanced lifestyle choices, and timely medical support can make a huge difference in improving fertility outcomes.
