First, chewing more can increase memory.
Japanese researchers have found that chewing can effectively prevent memory loss in the elderly. What people remember the latest is only stored in the hippocampus of the brain, which is a key part of human learning. This discovery holds that chewing is the most fundamental way for the elderly to maintain good memories. The researchers' analysis of the brain activity of people who are chewing shows that chewing does improve the signal activity of hippocampus, but how chewing stimulates the brain is still a mystery to be solved. Some people think that chewing can improve people's memory, because it can make people relax, because people often relieve themselves by chewing when they are nervous, and the hippocampus can control the level of hormones in the blood. Therefore, if the elderly chew less, their hormones are high enough to cause their short-term memory loss.
The correct method can make you get twice the result with half the effort: master the method and nourish your brain easily.
Second, nagging encourages memory.
Women love to nag, especially elderly women, which helps women to prolong their memory and life span to some extent. A 20-year-long psychological study in the United States shows that the mental health indicators of the elderly are different between men and women, and 90% of them are above average. Experts believe that women are better than men at adapting to old age and are more willing to communicate with others; When men get old, they are mostly silent. Speech is an indispensable way of psychological catharsis, which can prevent memory decline.
Third, choose diet to help memory.
From 65438 to 0965, researchers in Hawaii began to study the eating habits of 8006 Japanese-Americans to understand the correlation between diet and diseases. The researchers suggest that it is a good choice to take a proper amount of "healthy fat" to reduce the occurrence of thrombosis, such as polyunsaturated fatty acids (olive oil and fish oil) to maintain normal blood circulation; It is also important to eat foods with high antioxidant content, and should eat more foods rich in vitamin E; Vegetables and fruits rich in vitamins and minerals are also good choices to keep healthy.
Diet also nourishes the brain: eating beef makes people smarter.
Fourth, play more to stimulate intelligence.
Dr. Wilkes of Einstein Medical College in the United States conducted a study on amnesia in the elderly over 75 years old. The results show that physical activity can improve health, while mental activity can significantly reduce the risk of memory decline. Dancing, playing musical instruments, reading, playing cards, crossword puzzles and learning foreign languages can increase the number of nerve synapses, enhance the signal transmission between nerve cells and consolidate memory.
5. Exercise and fitness can prevent memory loss.
We usually think that people are born with a brain, and with the growth of age, the brain will gradually decline until death. Now we find that there are many factors that can promote the self-renewal of the brain, and exercise is one of them. Urbana university Colcomb, Illinois, said that long-term cardiovascular exercise can reduce brain tissue loss caused by aging. A decrease in brain tissue loss means a decrease in memory loss.
Sixth, talk about emotional pleasure.
Swedish medical researchers have followed up 989 middle-aged and elderly people aged 50-60 for 9 years, and found that the rate of Alzheimer's disease in divorced or widowed people is 22%, while that in married couples is only 14%. Therefore, scientists believe that the elderly should not be insulated from love. Two of a kind's happiness will make the elderly couple secrete some hormones and acetylcholine, which will help to enhance the immune function, delay the aging of the brain and make the elderly think actively.
