1, insist on napping (1) in Japan, there is a survey, there are napping habits of drivers than no napping habits of drivers with much lower risk of traffic accidents. (2) about napping, in recent years, a larger survey in 2007, Harvard study of 24,000 adults found that, compared with people who do not nap, the likelihood of death from heart disease will be reduced by 40% for people who nap. The human body needs sleep during the day in addition to the night. At 9 a.m., 1 p.m. and 5 p.m., there are three sleep peaks, especially at 1 p.m. The peak is more pronounced. (3) daytime nap for about a quarter of an hour is appropriate, preferably not more than half an hour. If the nap time is too long, but will appear awake but the feeling of slow reaction. 2, a fish a week (1) in 2014, a study published in the American Journal shows that eating non-fried fish at least once a week can help improve brain health and improve memory. (2) Fish contains a large amount of Omega-3 fatty acids, which help improve brain health, and it is recommended that adults consume 50-100 grams of fish and shrimp daily. For older people over 65 years old, eating fish can reduce the risk of dementia, it should be noted that it is best not to eat fried fish, high-temperature oil will destroy the Omega-3 fatty acids contained in fish. 3, outdoor walking and walking (1) the body is lazy, the brain more difficult. In 2014, a study in the United States said that participation in group outdoor walks can significantly reduce the risk of depression, and reduce the feeling of stress in life, and improve people’s motivation for life. (2) Aerobic exercise is good for heart health, and some movements that require coordination of the limbs can activate the cerebellum, promote thinking, and improve cognition and information processing speed. American magazine has reported that people over 60 years of age, 3 days a week, walking for more than 45 minutes each time, can prevent Alzheimer’s disease. Walking for more than 7 hours a week can reduce the incidence of breast cancer by 20%. (3) From a fitness perspective, walking is an inexpensive, low-risk, yet convenient form of aerobic exercise. Wear a pair of light sneakers, go out every morning and evening to walk a few laps, legs steadily forward, arms swing up, the cardiovascular system also benefit. 4, try to chat more (1) a series of experimental studies in the United States found that: when several people gossip together, or even bad-mouthing others, their friendship can often develop by leaps and bounds. (2) seemingly idle chatter, in fact, physical and mental strength is a kind of exercise. Chatting is a brain process, and the process of older adults communicating with others is also brain training to exercise their reactions and language skills. (3) With age, the elderly are constantly surrounded by people passing away, which will affect their emotions, while some elderly people leave the familiar environment to live with their children, coupled with the elderly tend to have a low opinion of themselves, prone to insecurity, “so children should often accompany their parents to chat.” 5.Breathing fresh air (1) The plan of the day lies in the morning. Early in the morning at 8 o’clock, a wake-up call, what you need most is perhaps to go out for a walk, sunbathing, breathing fresh air are good choices. (2) U.S. researchers recently found that people who took a walk in the countryside improved their short-term memory by 20%, and nature can make people calm and relaxed, which helps them focus. (3) And sun exposure can also make the mood happy and prevent vitamin D deficiency. Vitamin D deficiency leads to an increased incidence of Alzheimer’s disease. (4) However, one reason that prevents people from going out is the hazy air in the city. If you encounter early morning hazy weather, when the outdoors is not suitable for exercise, you may choose to do yoga at home, or go to the gym for exercise. The home can also buy reliable quality air purifier to make the air at home more fresh. 6, challenge memory (1) the more the brain is used the more intelligent the old saying is based on science. (2) Japanese experts say that people produce theta waves when remembering something will be transmitted to the hippocampus area of the brain, stimulating the memory function of brain nerve cells in this area. (3) When doing clinical analysis of dementia scale, education is also one of the factors assessed by the scale. Some studies have shown that the lower the education and the less brain work after retirement, the higher the incidence and aggravation rate of dementia. (4) Therefore, often do some memory-challenging games and activities can slow down brain aging. 2011, a study reported that the action of chewing gum, which allows the brain to get more blood and nutrient supply, which may enhance memory capacity. 7, do housework diligently (1) Many people feel that doing housework is trivial and troublesome. In fact, housework well done, the brain’s planning and co-ordination ability is also good, to pack things back up, but also to slow memory loss, relaxation and exercise the brain are good. (2) For example, drying quilts and clothes requires stretching the body, washing dirty and greasy dishes, and tidying up and cleaning dirty rooms will give a strong sense of accomplishment and bring pleasure to the brain.
