A man with wrinkles on this part is doomed to die young.

Wrinkles are often seen as a sign of skin aging. Many people worry that wrinkles affect their beauty and youthfulness. However, wrinkles can also reveal some potential health problems. The American website Prevention recently summarized five hidden health risks that can be seen from wrinkles.

Risk of osteoporosis. Researchers at Yale University in the United States found that the skin is a window to bone health. After investigating more than 100 women in menopause, the researchers found that women with the most and deepest wrinkles also had the lowest bone density. The person in charge of the study said that collagen is an important component of bones and skin, and its amount decreases with age.

Early stage of heart disease. Diagonal wrinkles on the earlobes may be an early warning of heart problems. A study by Cedars-Sinai Medical Center in Los Angeles found that people with such creases on their earlobes are more likely to be diagnosed with heart disease. Experts believe that these wrinkles are caused by the collapse of tiny blood vessels flowing to the earlobes, which can reflect changes in the blood vessels around the heart.

High blood pressure. Researchers at Leiden University Medical Center in the Netherlands found that women who looked younger than they actually were and had fewer wrinkles had lower blood pressure. The study also showed that participants from long-lived families were less likely to have wrinkles on their upper arms than their peers.

Too much stress. Anxiety and worry can cause wrinkles. Janet Prestovsky, a dermatologist in New York City, said: When people are under stress, they will frown, and over time, permanent wrinkles will form on the forehead. Wrinkles in other areas of the face are also related to the fact that constant anxiety causes the body to release a large amount of stress hormones, which degrades the collagen in the skin.

Eating too many sweets. Eating sweets will cause sugar to attach to protein, which will easily form "advanced glycation end products" in the human body. This substance will break down collagen and elastin, causing more fine lines and wrinkles on the skin. Researchers suggest: It is best to replace sweets with fruits, because most fruits have anti-glycation properties and can reverse skin damage.
