睡眠决定寿命每天睡几个小时可长寿（Sleep determines life and sleeps a few hours a day for long life）Sleep determines life and sleeps a few hours a day for long lifeOne day must be 8 hours of sleep? According to the American Cancer Society, the average person who sleeps 7~8 hours per night has the longest life expectancy; 80% of people who sleep less than 4 hours a night are short lived. But Guo Xiheng, director of the center for respiratory diseases diagnosis and treatment at Beijing Chaoyang Hospital, also pointed out that the best sleeping time for different age groups is different, and should be scientifically sleep according to their age.Sleep determines life (picture: Oriental IC)People over 60: sleep 5.5~7 hours every dayThe old should go to bed at 12 every night, and sleep at night for 7 hours, or even 5.5 hours. Alzheimer's association data show that people who sleep within 7 hours of sleep each night can age their brain for 2 years. Long term sleep more than 7 hours or lack of sleep will lead to poor attention, even Alzheimer's disease, increased risk of early death.Recommendation: the most common sleep problems in the elderly are dreaming and insomnia. Dreaming is due to the deterioration of the brain function of the elderly. Insomnia is caused by the decrease of melatonin secretion in vivo, and melatonin is one of the important factors that determine sleep in vivo. Guo Xiheng suggested that night sleep quality is bad for the elderly,it is best to develop a lunch break, the time does not exceed 1 hours. Otherwise, the brain central nerve will be more inhibited, causing the brain blood flow is relatively reduced, the body metabolism slowed down, easily lead to wake up uncomfortable, or even more sleepy.30~60 year old adult: sleeps 7 hours every day or soAdult men need 6.49 hours of sleep, women need about 7.5 hours, and should ensure that 10 in the evening to 5 in the morning, "high quality sleep time."". Because at this time people reach the state of deep sleep, helps relieve fatigue. The 22 year study in Finland in a study of 21 thousand adults found that sleep less than 7 hours for men, the risk of death was 26% higher than sleep 7~8 hours of male, female 21% higher; sleep more than 8 hours of men, the risk of death was 24% higher than sleep 7~8 hours of male, female 17% higher.Recommendation: if the person of this age group lacks sleep, it is related to bad habits such as mental deterioration or overeating caused by stress. Guo Xiheng reminds, besides relieving the pressure as far as possible, but also can do something in the sleeping environment, such as reducing noise, ventilation, proper shading, etc., and choose 10~15 cm high, soft and moderate pillows. People who still don't sleep enough can sleep through 1 hours of lunch break. 13~29 year olds: sleep for about 8 hours every dayTeenagers of this age usually need to sleep 8 hours a day, and follow the principle of early to bed and early to rise, and ensure deep sleep at about 3 in the evening. You should usuallygo to bed at 24, get up at 6, and try not to sleep late on weekends. Because the sleep time is too long, will disrupt the body clock, resulting in lack of energy, the impact of memory, and will miss the breakfast, caused by eating disorders.Recommendations: young people are accustomed to staying up late, which will directly affect their mental state for second days, and easy to damage the skin, acne, acne, chloasma and other issues. Long stay up late will affect the endocrine, leading to decreased immunity, colds, gastrointestinal infections, allergies and so on will find the door,There will be forgetfulness, irritability, anxiety and other mental symptoms. Therefore, the most important thing for young people is to regulate their own lives. Do not eat 1 hours before going to sleep, and take half an hour's nap at noon, which is more beneficial to your health.4~12 year old child: sleeps 10~12 hours every dayIt is necessary for children 4~10 years of age to sleep 12 hours a day, go to bed at about 8 every night, and take a nap at noon as soon as possible. Older children sleep 10 hours, or even 8 hours, enough. Capital Institute of Pediatrics, deputy director of department physician Li Haiying told reporters that if the children lack of sleep will not only Jingshenbuzhen, low immunity, but also affect the growth and development. But she warned that sleeping time should not be too long, if more than 12 hours, may lead to obesity.Recommendation: children do not have sleep disorders at all,as long as a good environment is available. Don't eat before going to bed, the bedroom not too bright lights or more exciting music; best together with the children a timetable, urging them to sleep before going to bed; let the child do some preparatory work, such as brushing teeth, wash bed, etc., this process may seem simple, but in the child that go to sleep". 1~3 year olds: 12 hours per night, two or three hours during the dayThe child should sleep 12 hours a night and two or three hours a day during the day. Specific sleep times can be determined according to their own sleep rhythms, such as some babies getting used to sleeping at noon and later in the afternoon.Suggestion: the baby of this age is easy to sleep because of too much excitement. Sometimes, they got to sleep, the brain is still active; asleep, often being kicked, molar, bedwetting. These can affect the baby's brain and body development. Therefore, parents are advised to take a warm bath for 1 hours before the baby's bedtime, relax the whole body, tell a little story or put on some relaxing and soothing music, and also help to sleep.Infants under 1 years of age: 16 hours per dayBabies under 1 have the most sleep, about 16 hours a day. Sleep is an important period of growth and development of infants aged within 8 months so sleep time must be guaranteed.Recommendation: most of the baby's sleep problems are caused by calcium deficiency, daytime fright and digestive disorders. Some children sleep too much at night because they sleep toomuch during the day. In this regard, parents should pay attention to the children, scientific feeding; also need to try to ensure the baby sleep at night is not complete, frequent nocturnal feeding or changing diapers, especially after midnight, because few month old baby in the secretion of hormone in the fastest after midnight.Which type of blood group determines longevity, and which type of blood group has the longest life span?Until now, there is no evidence that the United States has used the knowledge of blood type psychology in conscription to select people who are suitable for leadership. It is said that this method has long been introduced in japan. In any case, the research continued, supplemented and calculated, and drew exciting but surprising conclusions.Which blood group has the longest longevity?Type O blood has the longest longevityThe mathematician and Dr. Stephen.M. Weiss Berg (StevenM.Weissberg) with the well-known fitness expert Joseph Christiano (JosephChristiano) in the survey of 5000 people in the interesting data.One question is, is there a difference in the average life expectancy of people with different blood types?The average life span of Americans is 76. This number is predestined. And it's delightful, because only a few peoplelive longer obviously, and the others die long ago.The person with the longest life expectancy is O type, whose average life expectancy is almost 87 years. They are nightmares of pension agencies. The plateau of life is not surprising because these people are physically strong, strong willed, psychologically balanced, and carefree.People with type B blood remain calm even if they die 10 years earlier than the type O blood. They are stubborn and cling to everything.Life expectancy is 10 years less, people with type AB blood are up to 70 years old.The average person who lived the shortest type of A was only 62 years old! In the psychologist's view, this is expected, because people with type A blood are thin and very sensitive, and they will always worry about themselves and their people. Unfortunately, this tends to overload the heart and even cause wastage.Which blood group has the longest longevity?But people with type A blood have shorter life expectancy than other blood types, and there is a very different reason. Dr Pete and.J., a doctor of medicine and a natural therapist, discovered the antagonism between certain foods and blood types. In one of his books he described the problem of matching people with food, because eating habits were influenced by blood type.He believes that the main difference between O blood type and blood type A person is the meat food digest: people with type O blood and need carnivorous, is well absorbed; while people with blood type A can be a good digestion of meat, cereals and vegetables need relatively more food. The basic reason is that there is a difference in the amount of gastric acid secretion: people with type O blood have enough stomach acid, so digesting meat is a piece of cake. Unfortunately, almost all of our recipes today are meat fast food: kebabs, hamburgers, roast sausages and steaks, which are just like poison to A blood people and their fragile digestive system. The wrong diet to make these people weakened, and shorten the service life.Let's take a look at the situation in japan. The country's A blood type has the longest life expectancy, higher than any other country. The answer is that they can treat diet right. The Japanese basically consume large amounts of fish, rice and bean products and treat their green tea as a treasure, just as the Bavaria people treat their beer. This diet is good for people with type A blood. Whoever wants to live longer must have a reasonable diet according to the blood type.Which blood group has the longest longevity?According to the Russian Communist Youth League Journal reported that Russian physicians have found a lot of blood type and disease related evidence, the following are their research results.Experts believe that people with blood type O longevity; people with type A blood almost no immunity to smallpox, mosquito bitesalso love them; people with type B blood are less cancer; and people with type AB blood have high immunity.People with type O blood are susceptible to disease, including stomach ulcers and duodenal diseases, cirrhosis, cholecystitis, appendicitis, bronchial asthma, abscess, etc.. Although usually easier to get sick, but the average life expectancy is significantly longer.People with blood type A susceptible Staphylococcus infection, Salmonella disease, tuberculosis, diphtheria, dysentery, influenza, rheumatism, atherosclerosis, myocardial infarction, epilepsy, chronic alcoholism and other diseases.People with type B blood are susceptible to diseases such as dysentery, influenza, nerve root inflammation, bone disease, urogenital system, arthritis, etc..People with type AB blood are susceptible to septic infections, acute respiratory diseases, viral hepatitis and other diseases. According to statistics, people with type AB blood suffer from schizophrenia more than 3 times higher than other types of blood, but type AB blood in the ratio of tuberculosis, pregnancy anemia is much lower than other types of blood.Which blood group has the longest longevity?Type B personality the most longevityIn the eyes of psychologists, personality is not only about destiny, but also about what you are suffering from." ChineseAcademy of Sciences Institute of psychology, director of the elderly psychological research center, said Li Juan, like blood type A, B, and O type, human character is divided into A, B, C, D four kinds, and closely related to the probability of human disease.Type A personalities zhengjianghaoqing, the concept of time and desire is very strong, and strive to occupy the leadership position, the pressure is relatively large, nervous, excited, their risk of hypertension, cardiovascular and cerebrovascular diseases is the ordinary people of the 2 - 3 times; type C personalities through interpersonal anxious, always swallow, repression, such a person is most likely to get cancer; type D personality is also called "distressed personality", the most obvious manifestation is negative and sorrow and loneliness, these are the risk factors for cardiovascular disease. "Heartless, laughing and talking" refers to the B type character, they are very satisfied with the present life, contentment, relaxation, no mood swings, so these people into the ranks of the highest probability of "longevity".The 84 year old Chinese medicine master Lu Guangshen head UFA, from the appearance point of view is about 50 years old, he summed up his health tips said: "I was a heartless person, what things are not personally." Lu Lao smiled and said he never read the first test, but is always the first assignment, because do not want to give myself so much pressure. He said: "when you have a positive mental state, the body's immune function will be better." Shanghai, Zhabei District's oldest 107 year old Bao Tingqin, the biggest feature is optimistic and cheerful. The old man has bad ears and can't hear others. But when he openshis mouth, he must be happy and nod his head. Bao Tingqin's daughter revealed that the old man did not "overnight worry", encountered trouble, and always sleep, it all disappeared.According to the China Elderly Association survey, in centenarians longevity reasons, genetic genes accounted for 15%, social factors accounted for 10%, medical treatment improvement accounted for 8%, climate conditions accounted for 7%, and the remaining 60% are dependent on the elderly themselves. One of the secrets of being in the first place is mentality."For the modern people, the anger is out of the mind, the gas is out, the urgency is made, and the disease is eating."."China chief health education expert Professor Hong Zhaoguang told reporters that he met a 94 year old man, hefatongyan, vigorous walking, looks like 60 years old. He asked the secret of longevity, what to eat supplements, what sports do, he smiled and said: "I have two words, called" laughing and talking, heartless. "." "Heartless" refers to the open-minded, small confused. "Talking and laughing" refers to optimistic and cheerful, something does not hold in mind. In the West there is a saying, "don't worry, don't get angry, don't use blood pressure meter."". Visible, cautious and angry is a major psychological barrier to longevity. So, to be a little confused, natural and unrestrained, a little wider mind.Which blood group has the longest longevity?A talkative person lives longBeijing has more than 1000 "anti-cancer star" investigation, almost all people think that the reason for survival is a good attitude, once the spirit of collapse, it is all over. Researchers at the University of Pittsburgh in the United States followed 90 thousand women for 8 years and found that people with an optimistic personality had a 14% lower mortality rate and a 9% lower risk of heart disease. A survey of 2015 cancer patients in Norway also found that those with a more sense of humor had a 70% higher survival rate than those with a poor sense of humor."To maintain a sunny attitude is far superior to any good doctor. It is not only beneficial to the coordination of the cerebral cortex and nerve, but also can enhance the immunity of the organism and delay senility." Professor Zhou Yujie, director of the twelve cardiovascular area at An Zhen Hospital in Beijing, Capital Medical University, said that studies show that cheerful people tend to be more immune than sensitive people. All sorts of bad moods can change your body on weekdays. For example, pulse, heartbeat, breathing appears to accelerate the symptoms will be angry; sorrow will make the digestive juice digestive gland secretion reduced, loss of appetite; fear, lying can make central nervous, always leads to increased blood pressure.This is because the secretion of people unhappy and happy of different substances -- secretion is not happy when the adrenaline is, this is a stress hormone, causes vasoconstriction, increased blood pressure, excessive secretion, can lead to hypertension and heart disease; happysecretion of endorphins, which can make the people feel good.No matter who is a nag, will make people complain incessantly. But in the eyes of Yang Jinsheng, a researcher at the Chinese Academy of traditional Chinese medicine, it is also a recipe for longevity. He believes that nagging can mobilize memory and language expression, but also exercise brain cells. People often talk, can make oral and throat muscles get exercise, is conducive to maintaining the patency of eustachian tube, the outer and inner ear pressure balance, health care for tinnitus, deafness, speech driven ocular and trigeminal motor, can also prevent presbyopia, senile cataract and visual acuity.Have a prescription for heart therapy"Better than medication diet, diet therapy". To a certain extent, a good drug is better than a reasonable meal, and a good meal is better than a good one. In response, several experts have opened a prescription for heart therapy.Laughter is a nutrient. Studies have shown that laughter can lower blood pressure; laughter for 1 minutes can lead to 10 minutes of rowing; laughter can also release stress and reduce depression;Laughter can stimulate the body's secretion of dopamine, causing euphoria. Middle aged and elderly people should have more contact with people with a sense of humor, more comedies and cartoons, and more comic dialogue."If therapy" is a medicine. The White House doctor gave Busha healthy recipe: if therapy, more than a week for at least 15 hours and family communication; communication between husband and wife every day at least two hours, including dinner or lunch.The friend is "not old Dan"". The long-term loneliness of the elderly can cause enormous social and psychological pressure, and may even cause endocrine disorders and decline in immune function. Australian researchers have found that people with a broad circle of friends live an average of 7 years. So, even the retired elderly, do not always hold back at home, we should strive to expand the circle of life, and old friends, and try to take the initiative to say hello to have neighbors.Tolerance is the regulating valve. In social contact, loss, misunderstanding and injustice are unavoidable. The best choice for these is to learn tolerance. A person who is not tolerant and knows how to make demands of others can easily cause nerve stimulation, vasoconstriction, and blood pressure, which can lead to a vicious cycle of psychology and physiology. And learn tolerance is tantamount to their psychological installed control valve.Indifferent is the immune agent. A little thing is a fool, but a great one. Worry about some trivial things all day long, the heart will be very tired. You may as well be smart and generous, keep a pleasant mood and a sense of inner satisfaction, and help to prolong life.。
