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.

Why Does Smoking Affect Your Physical Appearance?

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."

Visible Signs Of Smoking

Here are some visible signs of smoking in people, according to 2013, Lung India

Fingers and Nails

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.

Moustaches

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.

Lips

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.

Teeth

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.

Premature Wrinkling

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.

Nodular Elastosis

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.

Facial Wrinkling and COPD

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.

Heart failure has quietly emerged as one of India’s most serious and underestimated health challenges, driven by a rise in hypertension, diabetes, obesity, and delayed diagnosis of heart disease.

Due to a shortage of donor organs and a long waiting period before receiving the right treatment, end-stage heart failure patients in India faced a lot of difficulties a few years ago.

Today, advancements in heart transplant techniques are changing the situation from what was once an untreatable condition to a second chance at life.

Data from the National Organ and Tissue Transplant Organization (NOTTO) shows a significant year-on-year rise in heart transplants, with 253 transplants done in 2024, showcasing improved organ donation awareness, better coordination between hospitals, and stronger transplant networks.

What was once considered the only option is now emerging as a life-saving solution, offering patients not just a second chance but a return to a more meaningful and active life.

Why Are Heart Transplants Needed?

A heart transplant offers hope and gives a second life to patients whose hearts no longer support the body even after the best available medical aid.

Although it is never performed instantly, it becomes necessary whenever conditions of the heart result in end-stage heart failure, where the pumping function of the heart is compromised.

When medications and modern technologies cannot supply an adequate amount of blood and oxygen to the organs, patients experience extreme breathlessness, fluid buildup, fatigue, and repeated hospitalizations, making even simple activities like walking, eating, or lying flat exhausting.

As the flow of blood continues to deteriorate, failure is also expected in other vital organs such as the kidneys and liver. It is at this point that the transplantation of the donor heart is considered the only treatment option to ensure that the blood flow is normalized.

How Heart Transplantation Transforms Life?

Heart transplant is not just a surgical replacement of a failing organ, but a complete life restoration for patients with end-stage heart failure.

Its benefits include:

• Normalizes Heart Functioning: A healthy donor heart can immediately restore normal and effective blood flow. This will reduce weakness and fatigue that makes carrying out everyday tasks rather difficult.
• Enhances Survival Rates: Patients diagnosed with end-stage heart failure can only experience the best post-transplant survival outcomes when they undergo the transplant procedure as compared to other medical treatments.
• Enhances Quality of Life: The patients are able to attain independence once again as they are able to walk, sleep, travel, and socialize with their families and friends.
• Prevents Frequent Hospitalization: The successful transplant procedure prevents constant hospitalization, especially in cases with deteriorating heart failure, infections, and organ dysfunction.
• Protects Other Vital Organs: By restoring adequate blood flow, heart transplantation helps reverse damage to the kidneys, liver, and lungs caused by prolonged heart failure
• Permits Return to Normal Roles and Responsibilities: Patients regain their ability to work, take care of others, and carry out their daily responsibilities, which helps their emotional well-being.

Scottish Olympic legend Liz McColgan has warned athletes to wear sun protection during their training hours to protect their skin from “lasting consequences”.

Liz McColgan shared the health warning to athletes after undergoing surgery to remove lesions on her face.

The Olympic silver medalist from Dundee shared post-surgery photographs on the social media platform Instagram and lamented that, as a young runner, she never focused on wearing sun protection.

Avoiding sun cream because she felt it made her "sweat more" was her “ignorance”, said the 61-year-old former athlete.

“As a young athlete, I trained and raced in all weathers. Sun protection was never something I gave much thought to. In fact, I avoided it. I didn’t like the feeling of creams on my skin - I thought they made me sweat more, so I convinced myself I was better off without them. Looking back, that was ignorance,” Liz McColgan said.

“Recently, I had to undergo surgery to remove two lesions on my face. It was a stark reminder that the choices we make early on - especially the ones we dismiss as unimportant - can have lasting consequences,” she added.

Liz McColgan noted that athletes keep all their focus on "performance - mileage, sessions, recovery, nutrition”, but simple things like protecting their skin are often ignored.

“Yet it’s just as much a part of our overall health and wellbeing as any training session,” she said.

Sharing the health message to both young and old athletes, McColgan said, “Take sun protection seriously. Whether you’re training, racing, or even just spending time outdoors, protecting your skin matters.”

McColgan won a silver medal in the same event at the 1988 Olympic Games in Seoul. In 1991, she went on to win the 10,000m World Championships title in Tokyo.

Why Sunscreen Is Essential

Using sunscreen protects the skin from harmful ultraviolet (UV) radiation, which causes

• skin cancer,
• premature aging,
• painful sunburns.

Should Sunscreen Be Used Indoors Too?

Sunscreen is meant to be part of a daily skincare routine. But most people reach for sunscreen when heading to the beach or stepping out for a long day in the sun.

According to dermatologists, sunlight can still reach you indoors.

Dr Khushboo Jha, Chief Dermatologist Consultant at Metro Hospital, explains that sunlight entering through windows can still affect the skin.

“While standard window glass blocks most UVB rays, which cause sunburn, UVA rays can still pass through. These rays penetrate deeper into the skin and are linked to long-term concerns such as premature aging, uneven pigmentation, and loss of skin elasticity,” she said.

These UVA rays are often overlooked because they do not cause immediate redness or burning like UVB rays. However, over time, they can lead to visible signs of skin aging and pigmentation.

A Practical Approach To Daily Skincare

Dermatologists suggest viewing sunscreen as a preventive skincare habit rather than a rigid rule.

Dr Jha recommends incorporating sunscreen into your morning routine, particularly if your day includes stepping outdoors or spending time in naturally lit environments.

In simple terms, if daylight reaches your workspace or you plan to go outside later in the day, applying sunscreen in the morning is a small step that can help protect your skin over time.

Many men believe that as long as they feel healthy, active, and free from major illness, their fertility remains intact. While men do not have a sudden fertility cut-off like women, age still plays an important role when it comes to male fertility. Currently, a large number of men wish to start families later in life, often thinking their good health guarantees easy conception and fatherhood. They often neglect the age factor, even though it is linked to hormonal imbalance, stress, and genetic issues. A large number of men are unaware of their fertility health and continue to suffer. However, even in the absence of visible health problems, older men may face unexpected fertility challenges. Dr Madhukar J Shinde, Fertility Specialist at Nova IVF Fertility, PCMC, Pune, answered this for Health and Me.

Why do older men struggle with infertility?

Decline in sperm quality: Various studies have confirmed that as men age, sperm count, movement, and shape can slowly decline. Even if the numbers appear normal, DNA damage in sperm increases with age, which can reduce the chances of successful fertilisation.

1. Hormonal imbalance: It is important to note that testosterone levels naturally decrease over time. Lower testosterone can affect sperm production, sexual function, and overall reproductive performance, even when a man feels physically fit.
2. Some medical conditions tend to take a toll on fertility: Conditions such as diabetes, high blood pressure, and thyroid disorders become more common with age. These may be well-managed and symptom-free, but can still affect sperm health and fertility.
3. Stress and other lifestyle factors can impact fertility: Chronic stress, lack of sleep, smoking, alcohol consumption, or exposure to pollution can take a toll on sperm quality and lead to fertility issues that can be worrisome for men. Preservatives in a lot of frozen and junk food not only contribute to poor fertility health, but research suggests they may also affect DNA function. Therefore, men should stay vigilant.
4. Genetic issues: Advanced paternal age is associated with a higher risk of genetic mutations in sperm. This can further affect embryo development and increase the risk of miscarriage or certain developmental conditions.

Men must stay in touch with a fertility consultant who can design an appropriate treatment plan. The expert will evaluate them thoroughly and suggest lifestyle modifications such as a well-balanced diet, exercise, stress management through meditation, and medication for conditions such as diabetes, hypertension, and cholesterol. Awareness helps men take informed steps towards parenthood, even later in life. Certain pre-medications, including antioxidants advised by a fertility consultant, may significantly help in reducing DNA fragmentation, which contributes to poor sperm function. Therefore, men should prioritise their reproductive health, stay informed, and not suffer in silence.
