Smoking is considered to be one of the major causes of preventable deaths in the world, and millions of people are still grappling with the issue of quitting. Over 8 million people die annually due to smoking-related diseases. Out of them, heart disease, stroke, and COPD are the most threatening and common ones.
A lot of smokers desire to quit but are caught in the cravings, habits and withdrawal symptoms. That is why it is so necessary to know the dangers it has as well as the stop-smoking timeline.
This blog explores the effects of smoking on your heart, brain, and lungs; what your body gains upon giving up; and why now is the most opportune moment to abandon it.
How are Heart disease, stroke and COPD the triple threat?
The impact of smoking on the body is nearly equal on all body parts, yet none are as greatly impacted as your heart, blood vessels, and lungs. All three conditions combined create a vicious circle which kills the body gradually by killing it inside.
1. Heart Disease: The Silent Killer among Smokers
With each cigarette you smoke, you strain your heart. The tobacco toxins destroy the inner lining of your blood vessels, causing it to get narrow, stiff and inflamed. This raises the chances of coronary artery disease, heart attacks, high blood pressure, irregular heartbeat and sudden cardiac arrest.
Smoking also increases your heart rate and constricts blood supply, decreasing the oxygen available to your heart. Young smokers start to demonstrate the first signs of cardiovascular damage, even after some time.
2. Stroke: The Brain Runs Out of Blood
Stroke is a brain condition caused by a sudden loss of oxygen and blood that causes irreparable damage in just a few minutes. Smoking also poses a great risk, as it makes the blood thicker, shoots up the process of plaque formation, worsens the arteries, and causes a blood clot.
The risk is even greater in long-term smokers due to the fact that these effects may worsen with time. Stroke is happening at a younger age today, with the harmful effects of nicotine and tobacco on the body happening in younger adults as young as in their twenties and thirties.
3. COPD: The Smoker’s Disease that Takes Your Breath Away
COPD (Chronic Obstructive Pulmonary Disease) encompasses chronic bronchitis, emphysema and persistent difficulties during breathing. The number one cause is smoking, which slowly corrodes the lungs and makes them unable to perform their functions effectively.
Individuals with COPD also find themselves unable to perform simple daily tasks such as walking, using stairs or even speaking without experiencing shortness of breath. Despite the fact that COPD cannot be cured, smoking cessation can significantly reduce its evolution, enhance lung performance, and allow patients to gain control over their breathing process and quality of life.
What is the Stop Smoking Timeline: How Your Body Heals after You Stop Smoking.
The ability to see the speed at which the body bounces back is one of the greatest incentives to stop smoking. It does not matter how long you have smoked – six months or twenty years – the recovery process starts immediately. The following is a basic and inspirational stop-smoking plan that will illustrate the process that takes place at every level.
20 Minutes After Quitting
Only 20 minutes after you have smoked, your heart rate starts slowing down and your blood pressure starts returning to normal. This early improvement is important because smoking elevates heart rate by an average of 10-25 beats per minute. Even this small step is an indication of the start of recovery, as your cardiovascular system has been getting the first rest since you started smoking.
12 Hours After Quitting
Carbon monoxide in the blood gets back to normal levels within 12 hours. Carbon monoxide in smokers is frequently 3 to 10 times greater than that of non-smokers, so the blood is less able to deliver oxygen to the body. When you stop, you start to build up oxygen, which enhances circulation, boosts energy, and enables the heart and muscles to get the cleaner oxygen necessary to work.
24–48 Hours After Quitting
Over the first two days, the nerve endings begin to regenerate, and your sensorial ability of taste and smell starts to get better. It is also at this time that the body is full of nicotine; hence, withdrawal can be experienced at this point.
The risk of a heart attack is already starting to decline, cutting an attack on the heart by up to half in the first year. Applying aid programmes such as the QuitSure app assists in controlling cravings.
1 Week After Quitting
The lung functioning starts getting better after one week of quitting since mucus and toxins begin to clear. Smokers also tend to have lower efficiency of the lungs, which is as little as 30-40 per cent of that of a non-smoker.
This initial enhancement of respiration, vitality and sleep quality motivates most of the individuals to be determined. The mechanisms of the body to repair are activated, and the healing is evident in its daily activities.
1 Month After Quitting
The improvement of the lung capacity takes place after one month. According to the reports given by many smokers, the coughing and wheezing are significantly reduced, and stamina improves. The circulation is enhanced, and exercising is simplified.
The symptoms of COPD usually start to improve at this stage since the inflammation in the airways starts to reduce. This is a significant addition to the timeline of stop smoking, as the lung recovery is evident.
3–9 Months After Quitting
The improvement in lung function can be up to 30% between three and nine months based on smoking history and general health. It becomes easier to breathe, coughing is minimised, and the possibility of respiratory infection decreases significantly. Cilia – hair-like structures in the lungs – grow better and are more efficient; they aid in clearing of mucus and pollutants. An improved level of energy and lung strength is observed by many people during this period.
1 Year After Quitting
The risk of heart disease would be reduced by half after one year, as compared to a person who carries on smoking. Blood vessels get tougher and more supple, and the blood flow of oxygen is enhanced in the body.
This is a big step since heart disease is among the top causes of getting killed among smokers. Immunity, endurance and general performance of the cardiovascular system are also improved by many people.
5 Years After Quitting
The risk of stroke decreases to almost the same as that of a non-smoker five years after quitting. Smoking increases the chances of stroke by twice, but quitting causes a phenomenal change in the risk.
Arteries keep repairing, the amount of plaque also decreases, and blood clots become much less probable. At this point, your heart system has healed away much of the physical harm years – or decades – of smoking have inflicted on its structure.
10–15 Years After Quitting
The benefits are even greater after 10 to 15 years. The threat of lung cancer decreases significantly – numerous studies indicate a 30-50 per cent decrease in comparison to long-term smokers. The risk of heart disease is also made to be similar to that of a non-smoker who has lived a lifetime.
The development of COPD is reduced, so a large number of ex-smokers can afford lung stability. This is the last phase of the stop smoking schedule, which confirms that giving up smoking leads to significant time and health in life.
