How many cigarettes can the body bear a day? Reminder: If a person who loves to smoke has 3 symptoms, quit it

Uncle Sun, 73 years old, found a 2.5cm mass in his left lung during a physical examination 13 years ago. No metastasis was found in a comprehensive examination, so he underwent surgical treatment. It was a thoracotomy at that time. The postoperative pathology showed squamous cell carcinoma of the lung . Medium differentiation.

Uncle Sun has been actively cooperating with the doctor, recovered well after the operation, and did not receive any further treatment.

More than ten years later, Uncle Sun felt that his lung cancer was "very obedient" and he had completely controlled it, so he didn't think about regular checkups in the past few years.

However, this year Uncle Sun's old coughing problem has become more and more serious, especially in the middle of the night, he often wakes up from coughing . Under the urging of his daughter, Uncle Sun went to the hospital for a chest CT. He never thought that there was a huge mass of about 6 cm in his right lung . Through pathological biopsy, it was found to be small cell lung cancer.

It is obvious that cancer has been defeated once, why the tumor has changed its "identity" and made a comeback. It turned out that in the 6th year after the operation, Uncle Sun felt that he was in good control, so he picked up the long-lost cigarettes again, and smoked more than before.

Tobacco and alcohol make people love and hate. They are all sugar-coated devils, unknowingly putting their health into crisis.

1. Which is more harmful, a pack of cigarettes a day or two bottles of beer a day?

Which is more harmful to the body, tobacco or alcohol? According to the current research, there is still no accurate answer to this question, but what is certain is that both smoking and alcohol are harmful to health, and they are harmful without any benefit.

There is no so-called "safe amount" of alcohol, so what about smoking? How many cigarettes can the body bear a day?

Published in the "Lancet" sub-journal, a study from Columbia University included 25,352 people and followed up for up to 7 years. The results found that even if smoking less than 5 cigarettes a day, it will cause long-term damage to the lungs.

In fact, a study published in the British Medical Journal in 2018 found that even one cigarette a day poses a threat to cardiovascular disease. This study involving 7 million people and a meta-analysis of 55 papers pointed out that smoking can significantly increase people's risk of cardiovascular disease, but it has little to do with the amount of smoking.

Smoking not only harms yourself, but also harms others. When a cigarette is lit, the toxic substances in the smoke are released into the air. People who are passively exposed to tobacco smoke are as harmful as smoking.

Studies have shown that if a non-smoker lives with a smoker and smells smoke for 15 minutes a day for one year, the harm is equivalent to smoking by himself. The World Health Organization also pointed out that second-hand smoke increases the risk of lung cancer by 20%-30%, and also increases the risk of cardiovascular and cerebrovascular diseases and stroke.

How many packs of cigarettes a day will become a high-risk group for lung cancer?

To be clear, not all smokers will definitely get lung cancer, but smokers have a relatively higher probability of getting cancer. In clinical practice, the number of smoking will be calculated in pack years , and the specific announcement will be made:

The pack-year of smoking is equal to how many packs you smoke a day (a pack of 20) * smoking age (year)

For example, if one pack of cigarettes a day has been smoked for 30 years, the pack-year is equal to smoking 1 pack of cigarettes a day * 30 years of smoking age = 30 pack-years

Those who smoke more than 20 pack-years belong to the high-risk group of lung cancer.

2. The body will tell you: the lungs have been damaged, stop breathing

Smoking is tantamount to chronic suicide, and the toxic substances in tobacco are extremely harmful to the lungs. How to judge lung damage? In fact, the clues can be found through some signs of the body.

1. Lip color turns purple

Purple lips, scientifically known as cyanosis, is a manifestation of decreased oxygen saturation in the blood. Jin Hongzhong, director of the Dermatology Department of Peking Union Medical College Hospital, said that heart failure, cardiac insufficiency, and insufficient oxygen will cause insufficient oxygen in the venous blood, resulting in cyanotic damage. In addition, if there is a problem with the lungs, it will also cause the oxygen saturation to drop, causing the lips to turn purple.

2. The color of the face turns yellow

Long-term smokers, the skin will gradually turn yellow. This has to do with the phenomenon that harmful substances are transported to various parts of the body along with the blood circulation and accumulate over a long period of time. Long-term smoking will lead to a decline in the metabolic function of the lungs, so that toxins in the body cannot be discharged, and thus accumulate in the body, affecting the skin color of the human body to become yellow and dull.

3. Edema on the face

Most lung cancer patients develop edema when they develop into advanced stages. This is also caused by the metastasis of cancer cells in the body, which compresses the blood vessels and causes blockage. It may also be caused by cancer cells robbing nutrients and malnutrition in patients.

When you find these signs in your body and have long-term smoking habits, it is recommended to go to the hospital for examination in time.

3. Five behaviors that accelerate male aging, smoking is only one of them

If we talk about the harm of smoking, many people don't feel it for the time being and choose to ignore it. But for the human body, smoking will also accelerate the speed of aging, and aging is something that neither men nor women want to face. Aging brings not only changes in appearance, but also affects bodily functions.

A study published in the Nature sub-journal "Scientific Reports volume" in 2019 found that compared with non-smokers, smokers will experience a faster aging rate until the age of 55. And younger smokers experience higher rates of aging.

In addition, these behaviors can also accelerate male aging.

·stay up

Chronic sleep deprivation not only affects energy and concentration during the day, but may also affect skin function, damage skin integrity, and accelerate skin aging. Studies have found that people with good sleep quality can recover their skin three times faster than people with poor sleep quality.

·Sedentary

If people maintain a sitting posture for a long time, the muscle strength of the limbs will be weakened, and the limbs will be weak and prone to fatigue. Sitting for a long time can also easily cause gastrointestinal peristalsis to slow down, reduce digestive secretion, and aggravate indigestion. If the body cannot expel toxins in time, it will accelerate the aging of organs.

·Heavy taste diet

Occasionally eating heavy flavors does not have much impact on the body. However, a long-term heavy-tasting diet will easily lead to "glycosylation" or "high sodium" reactions, causing skin aging, relaxation, and loss of elasticity.

· eat too much

If you eat too much food, the human body needs to concentrate a lot of blood to digest the food in the stomach, which will cause insufficient blood supply to the skin, thereby accelerating the aging of the skin.

If you don't want your body to age quickly, it is best not to touch smoking. Those who smoke more than 20 pack-years belong to the high-risk group of lung cancer. When there are signs of disease in the body, it is best to check it out and quit smoking as soon as possible.
