A 2009 study has recently caused discussion on the Internet. It turns out that the two twin sisters in the photo look at least 10 years older! The researchers mentioned that one of the sisters had been smoking for 16 years and did not wear sunscreen at all, but the other sister who looked exactly the same did not smoke and usually wore sunscreen, which resulted in a serious difference in appearance. Doctors say that smoking reduces oxygen delivery and accelerates aging, and ultraviolet rays from the sun are also one of the most important causes of skin aging. They remind you to avoid 5 bad habits that cause aging.
This research report, which has recently caused discussion on the Internet, is said to have been conducted by the research unit for comparison with a pair of American twins, Jenny and Susan, who were both 61 years old at the time. It can be seen that although Jenny on the left has crow’s feet, nasolabial folds and a few dark spots and other normal aging phenomena, Susan on the right has dark spots on her face, dull skin, no elasticity, and very obvious wrinkles.

According to this research analysis, Susan has been smoking for 16 years. She has had the habit of sunbathing since she was 20 years old without sun protection. Later, she even moved to Florida, where the sun is the brightest. Jenny, on the other hand, does not smoke and tries to avoid sunbathing as much as possible. As a result, Susan looks at least 10 years older than her twin sisters!
Zhang Shunqin, director of the Department of Geriatric Medicine at Dalin Tzu Chi Hospital in Chiayi, said that in addition to natural aging, daily living habits and eating habits also affect the aging rate. Take the smoking and sun protection habits of the twin sisters in the aforementioned study, which are completely different in their lives. Studies have shown that smoking will accelerate vascular aging by 23%. Blood vessels are the conduits that supply blood oxygen to the whole body. The maintenance of the skin relies more on epidermal microcirculation. Vascular aging is systemic. Superficial micro-vessels harden faster than large blood vessels in the body. Therefore, smokers are prone to wrinkles, spots, and Loss of collagen.
Ultraviolet rays are the biggest killer of skin aging. Studies have shown that 80% of human appearance aging is caused by the damage of ultraviolet rays. Previously, the international medical journal “New England Journal” used a photo of a truck driver’s face to show the dangers of long-term exposure to the sun. The truck driver in the photo was 69 years old and had been engaged in transportation work for nearly 30 years. When driving every day, the left side of his face is turned outward. It has been exposed to direct sunlight for 30 years. As a result, compared with the right side of his face, his eyes are seriously droopy and full of wrinkles. His facial lines are also saggy and saggy. The smooth right side of the face, which is not exposed to direct sunlight, creates a strong contrast.

Zhang Shunqin reminded that although people will definitely age as they age, but by avoiding a few bad habits that will accelerate aging, you can maintain a better appearance and prolong the aging process even without undergoing cosmetic surgery:
1. Eat too much sugar
Sugary foods not only make people fatter, but according to a research report in the Journal of Clinical Dermatology, too much refined starch can cause “glycation”, which can destroy skin collagen and elastic fibers, prevent the body from repairing skin tissue, and accelerate aging.
2. Staying up late and not getting enough sleep
Everyone often talks about “getting beauty sleep”, and studies have proven that sleep is the time when the human body repairs itself. Lack of sleep affects skin repair and makes it prone to aging. Staying up late will increase inflammation in the human body, but people with good sleep quality will strengthen the skin barrier repair by 30% and reduce the degree of internal aging.
3.Drink
Alcohol will increase pore dilation, dehydration, dry skin, inflammation in the body and accelerate aging. Excessive drinking affects liver metabolism, damages the heart, and accelerates aging.
4. No exercise
Exercise can not only increase blood oxygen, strengthen cardiopulmonary function, and strengthen the immune system, exercise can also make muscles and skin firmer, less prone to sagging and wrinkles, and look younger. It can keep the heart, brain, and immunity in peak condition, as well as prevent Premature skin aging. The American Academy of Dermatology also stated that moderate exercise can make the skin younger. The American Heart Association recommends 30 minutes of moderate exercise every day to avoid heart disease and prevent aging.
5. Smoking
Smoking constricts and hardens blood vessels, reducing the supply of oxygen and nutrients to the skin. The American Academy of Dermatology points out that smoking will greatly accelerate skin aging. According to a research report in JAMA, the Journal of the American Medical Association, smokers have three times more wrinkles than non-smokers. Zhang Shunqin reminded that smoking behavior is often caused by “stress”. The more stressed people are, the easier it is to use smoking to convert stress. Stress has been found to be one of the killers of increasing inflammation and aging of the human body. Smokers who are stressed are even more harmful to A double whammy for beauty care.
