Do you smoke? Let's talk about it - Nirogi Lanka

Have you ever thought about that small but incredibly vital organ in your body: your heart? Think of it as your body’s tireless engine, roughly the size of your clenched fist. It works non-stop throughout the day, even while you sleep. Let’s dive into how this amazing organ functions, the health issues it can face, and the steps you can take to keep it strong and healthy with Nirogi Lanka.

What is Smoking?

Simply put, smoking involves burning a plant substance—typically tobacco wrapped in paper—to inhale its smoke into your mouth and lungs. As you inhale, the smoke travels through your airways into your lungs, where it enters your bloodstream and travels to your brain and every other organ in your body.

While this article focuses on tobacco cigarettes, many people also use cigars, pipes, marijuana (weed/pot), or even herbal cigarettes.

What is inside a cigarette?

Your typical store-bought cigarette contains three main components:

• Plant matter: In tobacco cigarettes, this consists of dried and processed leaves and stems of the Nicotiana tabacum plant.
• Rolling paper: The thin paper that holds the plant matter together.
• Filter: Designed to catch larger particles from the burning tobacco, though it does not prevent smoke, gases, and fine chemicals from reaching your lungs.

Why do people smoke?

People often start smoking seeking pleasure or excitement, but it quickly becomes difficult to quit. The primary reason is a physical dependence on the nicotine found in tobacco. When your brain is deprived of nicotine, you experience withdrawal symptoms that make you feel uncomfortable and restless.

Once nicotine reaches your brain, it triggers the release of chemicals that provide a temporary "reward." This is why you might feel:

• Relaxed and calm.
• Stimulated and alert.
• More focused on a task.

For many, smoking becomes a social ritual, much like having a morning coffee. You might smoke to unwind in social settings, boost your focus while working, or simply because you enjoy the habit or the physical sensation of holding a cigarette.

What does smoking do to your body?

Smoking affects everything from your skin and nails to your tissues, organs, and even the way your DNA functions. The damage begins the moment you light up. Thousands of chemicals released by burning tobacco begin their harmful journey the instant you take your first puff.

When you light up…

The heat releases nicotine and creates tar. As you bring the cigarette to your lips, tar stains your fingernails. The smoke dehydrates your skin and causes inflammation, which leads to premature wrinkles. Inhaling through your nose damages nerve endings, eventually reducing your sense of smell.

As you inhale the smoke…

Although the filter catches larger particles, tar, nicotine, and other toxins still enter your mouth. Tar stains your teeth, gums, and tongue. It wears down tooth enamel, making you prone to decay and gum disease, while also dulling your ability to taste your favorite foods.

As the smoke passes through your airways…

Tar coats your throat and vocal cords, often triggering a chronic cough. Worse, tar and hydrogen cyanide (a poisonous gas) paralyze your cilia—the tiny hair-like structures in your airways. Cilia are meant to sweep away dust and germs, and when they are damaged, you become highly susceptible to respiratory infections.

Once smoke reaches your lungs and bloodstream…

Smoke damages your alveoli (the tiny air sacs in your lungs), which can lead to emphysema, a condition within the COPD spectrum. Furthermore, carbon monoxide from the smoke enters your blood, binding to your red blood cells and preventing them from carrying oxygen to your tissues. This oxygen deprivation leads to shortness of breath and chronic inflammation. Meanwhile, nicotine damages the lining of your blood vessels, causing them to thicken and narrow, which significantly increases your risk of blood clots, heart attacks, and strokes. In men, this reduced circulation can also lead to erectile dysfunction.

When chemicals circulate throughout your body…

Once these toxins enter your bloodstream, they travel everywhere. If you feel sudden, severe chest pain or shortness of breath, please contact local emergency services immediately. They damage your organs systemically, including:

• Bones: Nicotine reduces calcium absorption and inhibits the production of bone-building cells. As a result, your bones become thinner and more fragile, increasing your risk of fractures.
• Eyes: The chemicals in cigarettes combined with reduced oxygen supply can severely damage your eyes. This significantly increases your risk of cataracts, macular degeneration, and even permanent vision loss.
• Immune System: Smoking triggers constant inflammation, which weakens your immune system. This leaves you more susceptible to infections and may increase your risk of developing autoimmune diseases.
• Hormones: Nicotine can disrupt your hormonal balance, which can directly impact your fertility.
• DNA: Toxic substances like arsenic, nickel, and radioactive polonium damage your DNA and block your body's natural repair mechanisms. This DNA damage is a primary driver of cancer development and can also cause fertility issues by damaging sperm cells.

How nicotine affects your brain…

Once nicotine enters your bloodstream, it travels directly to your brain. There, it activates specific receptors that trigger the release of 'feel-good' chemicals like dopamine, adrenaline, endorphins, and serotonin. This is what creates the ‘nicotine buzz.’ It acts like a switch that temporarily makes you feel relaxed, happy, or stimulated—all within seconds of your first puff.

Dealing with withdrawal…

Your liver metabolizes nicotine, and you typically excrete it through your urine within hours of your last cigarette. Once the ‘buzz’ fades, your body craves more, encouraging you to reach for another cigarette. If you don't, you will likely experience withdrawal symptoms, including restlessness, anxiety, depression, irritability, anger, and insomnia. Over time, your body develops a tolerance, meaning you need more nicotine to achieve that same feeling, ultimately leading to nicotine dependence.

If you are pregnant, your baby is also affected…

Smoking causes the blood vessels in the placenta and umbilical cord to narrow, which limits the blood supply reaching your baby. This blood contains carbon monoxide, nicotine, and other harmful chemicals. Consequently, your baby may not receive enough oxygen, and their developing DNA can be damaged. Pregnant women who smoke face a higher risk of miscarriage. Babies born to smokers are often at risk for low birth weight, heart and lung complications, and developmental delays.

What are the health effects of smoking?

While many people only associate smoking with lung cancer, the truth is that it can affect almost every part of your body, increasing the risk of numerous serious health conditions.

Can your lungs recover after you quit smoking?

Yes, if you quit smoking, your lungs and airways can begin to heal. Within weeks of quitting, inflammation and mucus production decrease, and after a few months, your cilia (the tiny hair-like structures in your airways) begin to regrow. While some damage (like COPD) may be permanent, your body begins a vital recovery process, and your risk for many life-threatening diseases drops significantly over time.

How do I quit smoking?

There are many proven ways to help you quit smoking. It may take some trial and error to find the method that works best for you.
