Generally speaking, when people find that their hair turns white, wrinkles appear and their strength is insufficient, they will realize that their body is in the stage of aging. In fact, the aging of the human body is not only manifested in these aspects, but also many signals will be displayed to you. Therefore, the following article will share the top ten signals indicating the aging of the body.
Stoop and hunchback
Generally, the bone mass of human body reaches the peak value around the age of 35, and then osteoporosis will appear in different degrees. However, the load on the body has not been reduced. Over time, it may cause atrophy or compression fracture of vertebrae and other bones supporting human body standing, and the back will also be hunched, and the human body will become shorter. When the hunchback is serious, the knee joint will also bend, and the average height will be shortened by 3-6cm, which may also cause thoracic deformity and affect the respiratory function, resulting in symptoms such as chest tightness, shortness of breath and dyspnea, increasing the risk of emphysema. The key to prevent hunchback is to prevent osteoporosis as early as possible. The best way is to exercise in the sun. The time is 8-10 a.m. and 4-7 p.m. the sun exposure for 20 minutes every day can promote the synthesis of vitamin D and the absorption of calcium. In food, we should drink more milk or yogurt, and eat more legumes, seafood, fish, eggs and other food.
Can't hold the urine
It is a common sign of aging that you often wake up at night and can't hold your urine. Christopher Eden, a urologist at the Royal Surrey hospital, said there had been a significant increase in the number of people getting up at night since they were about 50. This is because bladder aging has accelerated since the age of 40, and some people have difficulty "controlling" their bladder at the age of 65. When women enter menopause, the decrease of estrogen level leads to the thinner and weaker urethra tissue, the decrease of bladder support function, and the inability to hold urine. To prevent bladder aging, we should form the habit of not holding urine, especially for teachers, drivers and other professional groups. Don't drink water 2 hours before bedtime, and don't drink too much coffee, tea and other drinks 4 hours before bedtime.
Arthralgia
After the age of 40, human articular cartilage began to degenerate, and the joint space became narrower and narrower, which led to joint pain. When people go up and down stairs and squat up, they will feel uncomfortable. They will also have symptoms such as joint stiffness, swelling, and soft walking legs. Keep away from joint pain. First, control your weight and avoid increasing the burden on your knee. Second, exercise should be done according to your ability. Walking fast, walking slowly, indoor cycling, and raising your legs are relatively less harmful to your knee. Third, try to reduce the squatting and kneeling movements in your life. Don't squat to do housework or kneel to clean the floor.
There are black spots in front of me
Dr Rebecca Taylor, a spokesman for the American eye Association and an ophthalmologist, pointed out that as people grow older, black spots often appear in front of their eyes, just like flying mosquitoes, which is called flying mosquito disease. It is a relatively common physiological phenomenon, which is commonly seen in people over 40 years old. It is related to the degeneration of retina and vitreous, and sometimes it is also related to ocular diseases such as high myopia, retinal detachment, retinal vasculitis, high blood pressure, and vitreous hemorrhage caused by diabetes. Modern people rely too much on computers and mobile phones, and overuse of the eyes easily leads to premature deterioration of the eyes. There is no need to panic, but pay attention to scientific use of eyes. It is suggested to take a rest for an hour or so with your eyes; read less electronic screens and more paper books and newspapers. In addition, wearing sunglasses helps to avoid sun damage to the eyes, which can prevent eye aging. If you can't see the handwriting on the computer screen, please turn it up. Scientists at the University of California, Berkeley, found that every 2.8 points increase in font size can make reading tasks 8% easier.
Nose collapse
After the age of 40, some people began to have the phenomenon of nostril sagging, bridge of nose sinking, nose type change, etc., and felt that the nose seemed to be much larger than before. The nose is supported by cartilage. As cartilage gradually degenerates and atrophies, muscles and other soft tissues lack sufficient support, the nose will collapse. Once the nose aging, there will be decreased sense of smell, poor breathing, secretion, dry itch and other symptoms, the ability to resist bacteria also weakened. It is suggested to clean the nose with warm water frequently: hold the water in the palm of your hand, lower your head and inhale it gently with your nose, blow it out again and again several times; try to keep away from the irritating gases such as formaldehyde. Teeth grow
Dr John Colin, Dean of the school of Dentistry at the University of Central Lancashire in the UK, said that some people would be surprised to find that their teeth "grew longer" after they were 40, which is one of the signs of aging. Generally speaking, people's teeth begin to change color around the age of 30, and the enamel becomes thin; at the age of 40, the tooth bed begins to shrink, and the root is gradually exposed, and the length of teeth sometimes increases about 6 mm compared with that of young people. In addition, when eating stimulating food, teeth ache, teeth become brittle, cracks, red gums, bleeding, loose teeth and so on are all manifestations of aging. Dr. Mervyn druan, an expert at London dental beauty center, suggests that thorough brushing and flossing can help prevent gingival atrophy and maintain tooth health.
Voice change
John Rubin, an expert at the Royal National Hospital of Otolaryngology, said that generally speaking, men in their 70s or so began to thin their vocal cords, their vocal cords became less stable, their voice frequencies became higher, and their voice might become more sharp. Postmenopausal women due to lack of estrogen, vocal cord swelling easily, resulting in low voice. Therefore, it's best to avoid using your voice excessively in life to avoid damaging your vocal cords.
Poor elasticity of skin
Skin elasticity is one of the indexes to measure human aging. Pinch the skin on the back of the hand with the thumb and index finger, keep it for about 10 seconds, then release it, observe the rebound of the skin, and test the aging degree to a certain extent. The longer it takes for the skin to return to its original state, the less elastic it is. In order to maintain skin elasticity, you should stay up less, avoid smoking and alcohol, and do a good job in allergy prevention, sun protection, moisture preservation, etc.
tremor
Frequent shaking of hands is known as "idiopathic tremor" in medicine, which can occur in 20% of the elderly over 65 years old. According to Dr. Jane Sadler, a family medicine expert at Baylor medical system in Texas, most people don't need to pay too much attention to the hand shaking symptoms, but if it affects their daily life, they can have symptomatic treatment. Hand tremor may also be a sign of Parkinson's syndrome, hyperthyroidism, stroke and other more serious diseases, so it is best to see a doctor in time to determine the cause.
Metatarsal bone
Some people's toes bulge out a big bag, while their thumbs turn outwards. This is what people often call "big foot bone". Its scientific name is "hallux valgus", which is also a kind of "aging disease". According to statistics, at least 100 million people in China have hallux valgus. However, most people do not have correct diagnosis and treatment, which can lead to pollicitis and other diseases. According to the American Society of Podiatric Medicine, prevention and treatment of hallux valgus should be carried out as early as possible. It is recommended to wear more low-heeled shoes with a thickness of about 3cm at ordinary times, which is good for arch shock resistance and can limit excessive turning movement.
Generally speaking, once you find that you have the above ten signals in your daily life, you should be careful that it may be a warning that your body is aging. Therefore, doing a good job of maintenance and work in your daily life will become something that you need to pay extra attention to.
