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

The 73-year-old Uncle Sun found a 2.5cm mass in the left lung during a physical examination 13 years ago. No metastasis was found in the comprehensive examination, so he underwent surgical treatment. At that time, it was still a thoracotomy . Medium differentiation.

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

More than ten years have passed, and Uncle Sun feels that his lung cancer is "very obedient" and has been completely controlled. Therefore, in the past few years, he has not thought about regular check-ups.

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

He has already defeated cancer once, so why did the tumor make a comeback with a different "identity"? It turned out that in the sixth year after the operation, Uncle Sun felt that he was in good control, so he picked up the long-lost cigarette and smoked more than before.

Tobacco and alcohol make people love it and hate it. They are all demons dressed in "enjoyable" sugar, unknowingly putting health into crisis.

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

Tobacco or alcohol, which is more harmful to the body? According to the current research, there is still no accurate answer to this question, but what is certain is that tobacco and alcohol are both harmful to health, and they are all harmful.

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

Published in The Lancet, a Columbia University study that included 25,352 people and followed up for up to seven years found that smoking less than five cigarettes a day can cause long-term damage to the lungs.

In fact, in 2018, a study published in the British Medical Journal found that even one cigarette a day poses a threat to cardiovascular disease. The study, which involved 7 million people and a meta-analysis of 55 papers, found that smoking significantly increased people's risk of cardiovascular disease, but not with the amount of smoking.

And smoking not only hurts yourself, but also hurts others. When a cigarette is lit, the toxins in the smoke are blown into the air. People who are passively exposed to tobacco smoke are as harmful as smoking.

Studies have shown that non-smokers and smokers living together, smelling the smell of cigarettes for 15 minutes a day for 1 year, the harm is equivalent to smoking by themselves. The World Health Organization also pointed out that second-hand smoke can increase the risk of lung cancer by 20% to 30%, and also increase the risk of cardiovascular and cerebrovascular diseases, stroke, etc.

Smoking a few packs of cigarettes a day will become a high-risk group of lung cancer?

To be clear, not all smokers will get lung cancer, but smokers have a relatively higher probability of developing cancer. In clinical practice, the number of cigarettes smoked in pack years will be calculated , with specific announcements:

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

For example, if you smoke a pack of cigarettes a day for 30 years, the pack year is equal to smoking 1 pack of cigarettes a day * 30 years of smoking age = 30 pack years

Smoking more than or equal to 20 pack-years belongs to the high-risk group of lung cancer.

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

Smoking is equivalent to chronic suicide, and the toxic substances in tobacco are extremely harmful to the lungs. How can you tell if your lungs are damaged? In fact, you can find clues through some physical signs.

1. Lips turn purple

Purple lips, scientifically called cyanosis, is a sign of a drop in oxygen saturation in the blood. Jin Hongzhong, director of the Department of Dermatology of Peking Union Medical College Hospital, said that when heart failure, cardiac insufficiency, and insufficient oxygen, it will cause insufficient venous blood oxygen, resulting in cyanosis-like damage. In addition, problems with the lungs can also cause the oxygen saturation to drop, causing the lips to turn blue.

2. The color of the face turns yellow

Long-term smokers, the skin will gradually turn yellow. This is related to the phenomenon that harmful substances are transported to various places in the body along with the blood circulation, and accumulate in the past for a long time. Long-term smoking will lead to a decline in the metabolic function of the lungs, so that the toxins in the body cannot be excreted, thus accumulating in the body, affecting the skin color of the human body to become yellow and dull.

3. Swelling of the face

Most lung cancer patients will develop edema in the advanced stage. This is also caused by the metastasis of cancer cells in the body, which is caused by the blockage of the blood vessels. It may also be caused by the cancer cells robbing nutrients and malnutrition in the patients.

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

3. 5 behaviors that accelerate male aging, smoking is only one of them

If we talk about the harm of smoking, many people do not feel it temporarily and choose to ignore it. But for the human body, smoking will also accelerate the speed of aging, and aging is something that both men and women do not want to face. Aging brings not only changes in appearance, but also affects physical functions.

A 2019 study published in the Nature sub-journal "Scientific Reportsvolume" found that smokers age faster than non-smokers 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 daytime energy and focus, but may also affect skin function, compromise skin integrity, and accelerate skin aging. Studies have found that people with good sleep quality recover their skin three times faster than those with poor sleep.

· Sedentary

If a person maintains a sitting posture for a long time, the muscle strength of the limbs will be weakened, and the limbs will be weak and easily fatigued. Sitting for a long time can also easily cause gastrointestinal motility to slow down, reduce digestive secretion, and aggravate the body's indigestion. If the body cannot excrete toxins in time, it will accelerate the aging of organs.

·Heavy taste diet

Occasionally eating heavy flavors will not have much impact on the body. However, a long-term heavy-taste diet will easily lead to "glycosylation" or "high sodium" reactions, which will cause the skin to age, relax, and lose elasticity.

·Eating too much

Excessive intake of food, the human body needs to concentrate a lot of blood to digest the food in the stomach, it 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, smoking is best not to touch. Smoking more than or equal to 20 pack-years belongs to the high-risk group of lung cancer. When the body shows signs of disease, it is best to get checked and quit smoking as soon as possible.
