1. Sleeping on your side can fully relax your brain.
It is often said that people should "stand like a pine and cypress, sit like a bell and lie like a bow". In fact, lying like a bow emphasizes that people should sleep like a bow, which is called lateral sleeping.
Curling up in the mother's body like a fetus is the healthiest posture, because in this posture, the brain is fully relaxed. About sleeping posture, modern medicine also pays attention to lying on the side, and lying on the right side is better.
The reason is that the heart is not compressed when lying on the right side, and the liver is on the right side. When lying on the right side, blood is more likely to flow back to the liver, which is a maintenance process for the liver itself.
If we look at this problem from the perspective of human evolution, the right sleeping position is the best way to relieve fatigue and the most relaxing sleeping position for the brain.
One function of our cerebral cortex is to make the body tense and less relaxed. This is the embodiment of a young and healthy person. So young people will look tall and straight, while old people will look depressed. It is the brain that unconsciously regulates muscle tension.
However, in this tense process, the brain consumes energy. Even if you don't think, even if you don't realize it, this energy consumption is always going on.
Because of energy consumption, we need to have a rest. Posture during sleep is naturally very important, which determines the quality of sleep. So, first of all, you have to take a posture that your brain can't work hard at all.
If you lie on your back, your limbs are usually extended. In fact, this sleeping position will make your skeletal muscles tense. If you lie on your back all night, the first thing is that it is difficult for you to fall asleep. Even if I fall asleep, I will be very tired in the morning.
However, if you curl up together, like a bow, or like a fetus in a mother's body, muscles don't need any strength. This posture is easy to make people fall asleep, and the quality of sleep is also high, because in this posture, the brain cancels all "control" of skeletal muscle and can breathe a sigh of relief.
The reason why the fetus kept this posture was because the cerebral cortex was not fully developed at that time and could not control the muscles. Muscles naturally adopt the most relaxed and primitive posture.
If you can go back to sleep and keep this primitive state, it is actually to ensure that the brain can be relaxed in a state of "off work".
Not just sleeping. When we look at people's posture when they are tired, we will involuntarily collapse, relax our shoulders and akimbo our hands. At this time, the skeletal muscles of the body are relaxed. The reason why I am relaxed is because my brain is tired and I can't control my subordinates.
On the other hand, if you take the initiative to adopt this relaxed attitude, it will also save energy for your brain, and you can relax your brain by being fired.
2. How to relax the brain
1. Drive your brain cells
Studies show that people who get enough exercise have better brains.
Scientists at the Sack Institute of Biology in La Jolla, California, found that compared with mice sitting in online chat rooms all day talking about The Lord of the Rings, the hippocampus of adult mice who want to run on wheels gets twice as many new cells as they do, and the hippocampus is the part of the brain that controls learning and memory.
Researchers are not sure why the brains of more active rodents have this reaction, but what they can know is that this kind of voluntary exercise can reduce stress and is therefore more beneficial. This means that finding a way to enjoy exercise instead of forcing yourself to exercise will make you smarter and happier.
So, do some sports, choose training programs such as marathon, triathlon or "fun race", or find a partner to make sports interesting.
2. Exercise your mind
It's not just physical exercise that makes your brain cells active. Just like taxi drivers and piano players, you can build them by using various areas in your brain.
Lawrence C. Katz, a professor of neurobiology at Duke University, is also the co-author of Keeping the Brain Fresh. Finding a simple way to use the degenerated part of the brain not only helps to maintain nerve cells, but also helps dendrites and axons on cells to receive and transmit information.
Katz said, just as new weightlifting helps to exercise underutilized muscles, thinking and observing the world in a novel way helps to improve the function of inactive parts of the brain.
Experience new tastes and smells; Do things with hands that you don't usually use; Find some new ways to drive to work; Travel to new places; Performing artistic creation; Read Dostoevsky's novels; Write a brotherly comedy for Ted Kennedy and Rush Lin Bao-basically, do everything possible to make your brain abnormal.
3. Ask more why
Our brains are linked with curiosity. As we grow up and become "mature", many people begin to suppress or deny their natural curiosity. Make you curious! Ask yourself why these things happen.
Ask someone who knows. The best way to exercise curiosity is to ask, "Why? Get into the habit of asking at least ten "why" every day. Your brain will become happy and you will be surprised to find that there are so many opportunities and solutions in your life and work.
laugh out loud
Scientists tell us that laughter is good for health; It can promote the release of endorphins and other positive chemicals in the body. In fact, I don't need scientists to tell us that laughter can bring good feelings. Laughter can help us decompress and break old patterns. Therefore, laughter can be seen as a quick charge to the brain. Laugh a lot!
Step 5 be a fish head
Omega-3 oil exists in walnuts, flaxseed, especially fish, and has long been sold as a health care product beneficial to the heart. But recent research shows that it is also a brain booster, not only because it helps the circulatory system to deliver oxygen to the brain.
It can also improve the cell membrane function of brain cells, which may explain why people who eat a lot of fish are not prone to depression, mental decline and even attention disorder. Scientists have noticed that fatty acids are necessary for the normal development of children's brains, and they are added to the infant's diet formula.
Eating enough of this oil can improve your brain power and even your intelligence. Eating fish such as salmon, sardines, mackerel and tuna at least three times a week is a good start.
6. Memory relaxes the brain
Find an old photo album or high school yearbook. Your brain is a memory machine, so give it a chance to work! Take some time to remember. Let your mind reflect on yourself, it will bring you positive emotions, and the new connection with memory will help your current work and challenges.
lose weight
Does disgusting fat make you stupid? Researchers at the University of Toronto found that when mice were fed a food containing 40% fat, their thinking function was weakened in some aspects, including memory, spatial recognition and rule learning.
The situation gets worse when the diet is full of fat, that is, food full of meat and milk. You may never look for dried cheese pieces in the maze, but these results still apply to you for two reasons: fat will reduce the flow of oxygen-enriched blood to the brain and reduce the metabolism of glucose, which is the food of the brain.
You can still get 30% of your daily calories from fat, but most of the rest should come from the aforementioned fish, olive oil, nuts and seeds. Whatever you do, you should be in stay away from obesity. Those biscuits and snacks are full of hardened oil.
8. Play guessing games
Some people like puzzles, crossword puzzles and logic games-it doesn't matter which game you choose. Doing some guessing games in your spare time is a good way to activate your brain and keep it in good working condition. Do some puzzles and have some fun, but do it while knowing that you are exercising your brain.
9. Mozart effect
More than a decade ago, Frances Lauhill, a psychologist at the University of Wisconsin, and her colleagues found that listening to Mozart's music can improve people's mathematical and spatial reasoning abilities.
Even if a mouse walks in a maze, listening to Mozart's music is faster and more accurate than listening to white noise or minimalist composer philip glass's music. Last year, Lausher reported that at least for mice, a Mozart sonata can stimulate the activity of three genes related to nerve cell signals in the brain.
This sounds like the most harmonious way to regulate mental function. But before you pick up the CD, see what you need to pay attention to. Not everyone who expected the Mozart effect found it.
Moreover, even its supporters believe that music improves the brain only because it makes listeners feel better-relaxed and excited at the same time-and similar stimuli can be done. In fact, a study found that listening to stories can also bring similar promotion.
10. Improve your skills.
As long as you want to expand your ability and knowledge, some repetitive mental stimulation is not bad.
Planting, sewing, playing bridge, reading, drawing and doing crossword puzzles are also valuable, but you should try different gardening skills and make more complicated sewing methods.
Play bridge with more talented opponents to increase skills, read articles by new authors in various fields, learn a new painting skill, and do more difficult crossword puzzles. Push your brain to a new height and make it healthy.
3. The danger of a man sleeping on his stomach
1, suffering from cervical spondylosis
For those who have no conditions to sleep in bed at noon, it is best not to sleep with their arms on their heads. Because burying one's head will cause the curvature of cervical spine to be opposite to the normal physiological curvature, and the muscles of shoulder and neck will be stiff because of maintaining an abnormal posture for a long time, so it is easy to get cervical spondylosis.
2, aggravate fatigue
Sleeping on your stomach can't completely relax your body. Some muscle groups, sweat glands and skin of your body will still be in a state of tension, which will not only make you feel energetic, but also make you feel more tired after sleeping.
3, numbness and pain
Sleeping on your stomach sometimes leads to discomfort in all parts of your body. For example, if the head leans on the arm for a long time, the blood circulation of the arm is blocked, the nerve conduction is affected, and symptoms such as numbness and soreness of the arm are prone to occur.
4, induce gastritis
Sleeping on your stomach first affects the digestive system. This is because it takes the human body at least 1 hour to empty the food in the stomach after a meal. It is easy to cause the stomach to be oppressed, increase the burden of peristalsis, easily cause flatulence in the stomach, reduce the ability of the stomach to digest food, and thus affect the absorption of human nutrition.
5, frequent nocturnal emission
Sleeping on your stomach can easily lead to nocturnal emission. Sleeping on your stomach for a long time will oppress the scrotum, stimulate Tintin, and easily cause frequent nocturnal emission. Frequent nocturnal emission can lead to dizziness, backache, fatigue, inattention, and even affect normal work and life. Young people are very sensitive to Tintin's stimulation, not to mention taking this sleeping position. Also, people who often have nocturnal emission should be careful that this sleeping position aggravates their illness.
6. Sperm injury and sperm loss
Sleeping on your stomach for a long time will reduce sperm quality. Men's scrotum is a small refrigerator for sperm, which needs to be kept at a constant temperature, which is conducive to the production of sperm. If a man sleeps on his stomach for a long time, the scrotum temperature will rise, and it is not easy to dissipate heat in time, which naturally has a certain impact on sperm growth. Young male friends who are not married and have children need to pay attention.
