With the popularity of computers and the rapid development of the Internet, more and more middle-aged and older people have become “surfers.”
A new study from the United States shows that for the elderly.
With reading index books, surfing the web is more conducive to stimulating the brain’s nerves and exercise thinking.
Nowadays, through the widespread spread of computers, the Internet is playing an increasingly important role in people’s lives. The structure of netizens has begun to spread from young people to people of other ages. Many middle-aged and older people have become “surfers”.
So, for middle-aged and elderly people who are physically weak and have a slightly weaker health, what impact does it have to sit on the computer screen to surf the Internet?
Should middle-aged and elderly people pay attention to some matters?
Internet access is good for stimulating the brain. According to a recent study by the University of California, Los Angeles, for middle-aged and older people, surfing the Internet is more conducive to stimulating their brains and exercising thinking.
The school invited 24 volunteers between the ages of 55 and 76 to ask them to conduct online searches and readings, some of whom had online experience.
Scientists use MRI to monitor blood flow in the brain of volunteers. The results show that people who engage in two activities have significant blood flow in the brain that controls language, reading, vision, and memory.
However, below the time when the testers who frequently access the Internet conduct a web search, the activities in their brains that are responsible for determining decisions and handling complex objects are significantly increased, and are a pair of volunteers who conduct reading activities.
Studies have shown that using search engines to find information can produce the same brain-building effects as a puzzle game.
This shows that people can benefit the brain through the ever-changing network technology.
According to research results from the University of California, both reading books and surfing the Internet can achieve brain-building effects.
Because this part of the activity can stimulate the brain, which stimulates or enhances the brain’s response to information and improves the function of the brain.
Normal educational activities have an improved effect on the memory and intelligence of middle-aged and elderly people.
When people read and surf the Internet, they should concentrate and use their hands and eyes to find the information they need. At the same time, they can memorize, integrate, analyze, judge, and make decisions. Therefore, brain-related regional neurons are excited, neural network activation, and local blood flow.Increase, this is the physiological basis for reading and surfing the brain.
The stimulation of various sensory senses of the human body will be transformed into the corresponding parts of the cerebral cortex, which are transformed into brain cerebral cortex and processed by various processes. Visual, auditory, olfactory, tactile, pain, temperature, etc.
Among them, the visual and auditory, especially the visual weight, has the largest proportion, and the corresponding area in the cerebral cortex is relatively large, and the more complicated the stimulation signal, the wider the excitation area of the cerebral cortex.
Activities such as surfing the Internet and reading categories often have a significant impact on the nerve centers of language, vision, reading, and memory.
Regular reading and surfing the Internet help maintain a certain excitability of these related nerve centers, and it is helpful for middle-aged and elderly people to delay the deterioration of neurological aging.
Before the web search, the amount of information read is more, wider, more complicated, requires more cognitive participation, and requires more sustained attention and selective attention, recovery analysis ability and judgment ability, more brains.District participation, so web search can stimulate the brain more than reading.
However, Song Haiqing believes that there are 24 substituting small sample studies that can only provide a description of the phenomenon and the inference of possible mechanisms. It is not possible to rely solely on this data to determine the choice.
“They should only observe in these dialysis that online search can increase the activity of the corresponding area of the brain more than reading, and according to these phenomena, it is more beneficial to read online search than to read middle-aged and elderly people.
“Zhou Aihong said.
Middle-aged and elderly people should have moderate online search, use both hands and eyes, interact, and have a large amount of information. They can penetrate the stimulating intensity of the brain and exercise their responsiveness, thus having a brain-building effect. It should be said that it is applicable to other situations under certain circumstances.People of age.
But everything has a two-sided scale, and not all stimuli are good for the brain.
We advocate moderate access to the Internet, otherwise it will be detrimental to health. For example, sedentary prone to cervical vertebrae, soreness in the lower back, visual fatigue, and reduced physical activity.
Internet search requires more brains to make decisions and choices than normal reading.
This may be the cause of increased brain activity.
But the actual reading and online search is complicated.
Reading detective novels and reading news, searching for professional information online and watching gossip news, the excitement caused by different people is definitely different. It is not easy to make quantitative comparison under unified standards.
Moreover, even if there is such an effect on these middle-aged and elderly people, it cannot be simply promoted that this is a brain-enhancing activity suitable for people of all ages.
At the same time, it must be different from person to person, pay attention to control intensity.
This type of activity has a degree, and excessive Internet access is harmful to the body, a so-called “Internet addiction.”
Middle-aged and older people can go online to read news and search for the knowledge they need.
However, don’t be too long each time, you can move your legs and feet and take a rest.
At the same time, we must pay attention to peace of mind, try to see some extra information that makes people feel comfortable, and don’t be overly angry and excited about the negative information, especially those with high blood pressure and heart disease.
Appropriately combine regular mental activity with physical activity, pay attention to the right amount of time, do not affect the daily routine. With the advancement of technology, surfing has become an alternative lifestyle, but its impact on brain neural activity requires more research by experts to make it clear.
