The mystery of why some people appear to have healthy lungs despite a lifetime of smoking has been explained by UK scientists. The analysis of more than 50,000 people showed favourable mutations in people's DNA enhanced lung function and masked the deadly impact of smoking.
While there's no way to reverse scarring or lung damage that years of smoking can cause, there are things you can do to prevent further damage and improve your lung health.
1: Vaping is less harmful than smoking, but it's still not safe. E-cigarettes heat nicotine (extracted from tobacco), flavorings and other chemicals to create an aerosol that you inhale. Regular tobacco cigarettes contain 7,000 chemicals, many of which are toxic.
Lung disease: Vaping can make asthma and other existing lung diseases worse. Breathing in the harmful chemicals from vaping products can cause irreversible (cannot be cured) lung damage, lung disease and, in some cases, death.
“The biggest myth I hear is that if someone exercises they can offset the negative effects from smoking, but that's absolutely not the case,” says Susan Lakoski, M.D., associate professor of cancer prevention at MD Anderson Cancer Center.
Study finds some individuals have genetic variants that allow them to have long-term exposure to a carcinogen without developing lung cancer.
Some people who experience airway constrictions from certain conditions may find that smoking a cigarette may at times actually help them to breathe better. Sometimes they feel that this usage justifies smoking in their cases.
Background: Heavy smokers (those who smoke greater than or equal to 25 or more cigarettes a day) are a subgroup who place themselves and others at risk for harmful health consequences and also are those least likely to achieve cessation.
Smoking, anxiety and mood
Most smokers say they want to stop, but some continue because smoking seems to relieve stress and anxiety. It's a common belief that smoking helps you relax. But smoking actually increases anxiety and tension. Smokers are also more likely than non-smokers to develop depression over time.
Wheezing: Noisy breathing or wheezing is a sign that something unusual is blocking your lungs' airways or making them too narrow. Coughing up blood: If you are coughing up blood, it may be coming from your lungs or upper respiratory tract. Wherever it's coming from, it signals a health problem.
Regular exercise, eating a healthy diet, and avoiding tobacco smoke can all help keep your lungs functioning at their best. If you're experiencing symptoms of low lung capacity, such as shortness of breath, it's important to see a doctor to find out if an underlying condition is causing them.
“Regular cigarettes can cause lung cancer, breast cancer, heart disease, emphysema, and other diseases. However, it typically takes years, even decades for those conditions to develop. But with vaping, we're seeing lung damage developing in much less time; often under a year.
Exposure for just three days was enough to incur sufficient damage to their lungs, setting the stage for long-term chronic lung damage.
Quitting smoking reverses lung cell damage even for decade-long smokers. It's never too late to quit smoking, as a new study shows the lung's ability to heal and regrow damaged cells caused by cigarette smoking, even if they smoked for decades.
Research shows that a diet that includes tomatoes and fruits, especially apples, can reverse the damage caused to the lungs by smoking. Drinking carrot juice can also help in flushing the traces of nicotine from the body. Eating berries helps in removing tobacco toxins from the body.
