An article in Archives of Dermatology, an authoritative professional magazine in the United States, says that smoking will harm people's whole body skin.

It is found that a smoker who smokes a pack of cigarettes every day will have a certain degree of skin damage after smoking 1 year, which is as obvious as wrinkles on his face.

It is reported that the survey examined smokers and non-smokers of 4 1 respectively, and made a comparative study of the images taken by their right arms, involving the age group of 22-9 1 year.

Previous studies have shown that when the skin (especially the face) is exposed to strong light, the human skin will become rough, wrinkled and turn pale yellow. Researchers say that smoking can cause blood vessels in the deep skin to contract, reduce the blood supply to the skin, and then make the skin rough.

In view of the fact that tobacco contains many harmful substances, such as nicotine, nicotine, tobacco tar, radioactive substances, harmful metals and so on. For people who smoke a lot (such as smoking more than 1 box a day), under the long-term effect of these substances, many organs such as lung, heart and brain will be damaged to varying degrees, and the liver will also be implicated, which will weaken the function of the liver.

Hepatocytes in the liver are the main organs of bilirubin metabolism, and the damage of hepatocytes will affect the intake, combination, secretion and excretion of bilirubin, leading to the increase of serum bilirubin and the emergence of hepatocellular jaundice. Hepatocellular jaundice and intrahepatic cholestasis jaundice can be transformed into each other or both can coexist. At this time, bilirubin in the blood will increase due to the decline of liver function, leading to yellowing of the skin.

Extended data

Hazards of smoking:

1, affecting sleep

The latest survey by German scientific research institutions shows that smokers have less sleep time and poor sleep quality than non-smokers. Among them, nicotine is the chief culprit affecting sleep. Poor sleep quality will not only make people feel bad after waking up, but some studies also show that if the habitual sleep quality is poor, it will also lead to health problems such as obesity, diabetes and heart disease.

2, harm the reproductive system

Smoking can change the function of male reproductive system, make sperm abnormal development and weaken their vitality; Smoking can also inhibit the nerve center of the spinal cord and affect male sexual function.

According to research, men who smoke for a long time have 75% lower sperm fertilization ability than non-smokers. The culprit is nicotine in cigarettes, because sperm can recognize nicotine and respond to it. Long-term smoking will overload nicotine receptors in human sperm, thus reducing fertilization ability.

Smoking has a greater impact on women. First, smoking may lead to female infertility; Secondly, smoking can cause antidiuretic effect and increase oxytocin secretion in the posterior pituitary gland, leading to premature delivery, abortion and some comprehensive symptoms.

The incidence of pregnancy edema in smokers is 4: 1, and eclampsia is 29: 1. Thirdly, smoking will also affect the normal development of the fetus. If you stop smoking during pregnancy, you will reduce the above risks.

3, leading to lung disease

Smoking is one of the main causes of chronic bronchitis, emphysema and chronic airway obstruction. Smoking can cause changes in the structure and function of central and peripheral airways, alveoli and capillaries, and at the same time affect the immune system of the lungs, thus leading to lung diseases.

4. Carcinogenesis

It is an accepted fact that smoking causes cancer. Smoking is not only one of the important pathogenic factors of lung cancer (the risk of lung cancer of smokers is 13 times that of non-smokers), but also related to the occurrence of lip cancer, tongue cancer, oral cancer, esophageal cancer, gastric cancer, colon cancer, pancreatic cancer, renal cancer and cervical cancer. Studies have shown that carcinogens in smoke can also affect the fetus through the placenta, leading to a significant increase in the incidence of cancer in its offspring.
