Why can outdoor activities prevent myopia?

Medically speaking, outdoor activities can alleviate the blurred symptoms caused by staring at the screen for a long time through a long view, which is conducive to the prevention of myopia, but the distance view can not cure myopia, only prevention.

Outdoor activities, because when you move your eyes, it is far away and close, so it is still good for our eyes, and the air in an outdoor area is better, well, the colors are also richer.

It is not dazzling outdoors, it is better for glasses, and it is best to do more outdoor activities to prevent myopia.

The outdoor world is vast, and when you come out, you will definitely look at the sky, the ground, the surroundings, and the distance, which can naturally relieve the fatigue of your eyes.

The scattered light from natural light is good for our eyes.

When exercising outdoors, you can shine on the sun, the sun can promote the formation of vitamin D in the body, and will also secrete dopamine, which can have a good effect on regulating the myopia of the eyes.

Sunlight will promote people to produce vitamin D, vitamin D can enhance the body's calcium supplementation, for the eyes, calcium deficiency, elasticity makes the eye wall easy to weaken the surface tension, produce more dopamine in the sun, digging more can effectively inhibit the occurrence of myopia.

When exercising, the blood circulation of the eyes is better, when exercising, you will look at some green plants that protect the wild, when you exercise, you will make the eye muscles have a better adjustment, when you exercise, you can let your body absorb a lot of nutrients, and when you exercise, you will let the eyes have some activity, so that you can prevent myopia.

These principles are that you can broaden your vision, make your eyes move better, restore the brightness of your eyes by looking at the green landscape, better adjust the health of your eyes, and adjust the thickness of the lens.

Life is difficult to have smooth sailing, but whether it is for ourselves, for our families, or for our dreams, we can't stop working hard. May in the new year, all sweat will be harvested, and all efforts will not be disappointed.

No! I firmly believe that there must be a harvest for paying, there must be a fruit for sowing, people are good or bad for this harvest, more and less, the size of the fruit is another thing, and then think about it, I feel nothing! The quality of the harvest, the size of the fruit, this kind of power still belongs to us, "do my best", as long as you have worked hard, why care about the result?

As long as you have it, why care about the good or the bad? Only if you have done your best, why should you pay attention to the amount of gain?

Harvest, in the fall. Joy spreads in the fiber-filled air. People reaped the fruits and laughter, and a happy atmosphere filled the surroundings. Sowing in the spring, ploughing in the summer, and reaping in the autumn seems to be an eternal truth.

October is the harvest season, and the beautiful northern country is even more picturesque: you look at the endless rice fields, the rice waves are rolling, a golden yellow, like a golden ocean.

If you understand me, your affection is long, your heart is full of joy, and you can go all the way, and you will be smooth. Love**, flowers**, harvest**. Dipped in warmth, the water waves are stirred, and a pair of shadows are reflected. Inspiration came suddenly, and there was a beautiful article, which was refreshing and refreshing.

Those who only fantasize and do not act will never experience the joy of reaping the fruits.

Giving may not necessarily be rewarded; If you don't give, you won't get anything, and don't expect miracles.

In the eyes of a farmer, receiving golden fruits in autumn is success, harvest; In a student's view, making progress in learning and getting good grades is success and harvest; In a worker's view, producing better and more products is success and harvest; In a chef's opinion, making a beautiful and delicious dish is success and harvest.

We have a natural inertia, always thinking about suffering the least, taking the shortest detours, and getting the greatest benefits. There are some things that others can do for you, but they can't feel for you, and without this mental journey, even if you succeed, the spiritual field is still a barren. The happiness of success and the satisfaction of harvest are not at the end of the struggle, but in the process of struggle, the road you should take must be walked by yourself, and others cannot replace it.

Because it has less radiation to the eyes, it will not lead to overuse of the eyes, which is conducive to eye relaxation. Spending more time in nature is not only good for your eyes, but also good for your physical and mental health.

Because the outdoors is natural light, the natural environment is good for people's eyes and body. On the other hand, there are three-dimensional reasons for this. The outdoor environment itself is three-dimensional, coupled with the sunlight and light and dark shadows, so that the vision will have a strong sense of hierarchy.

When children are running and jumping, the eyes and three-dimensional objects form a relative motion relationship, which will be very beneficial to the health of the eyes.

At present, there are two recognized reasons for the prevention of myopia by sun exposure, one is that under strong light exposure, the pupil narrows to deepen the depth of field, reduce blur, and inhibit the occurrence of myopia; Second, it may be related to dopamine.

But whatever the reason, we can be sure that outdoor activities are an effective means of preventing myopia, and exposure to sunlight for 2 hours a day and more than 10 hours a week can reduce the incidence of myopia in adolescents by more than 10%.

Appropriate outdoor exercise can not only improve children's health, but also play a very key role in the prevention and control of myopia in children and adolescents. Daytime activities can not only prevent the occurrence of myopia, but also play a role in controlling the development of myopia for children who have developed myopia. As you just mentioned, some time ago, the guidelines for the prevention of myopia during the new crown pneumonia period for children and adolescents were issued, and the "Guidelines" specifically mentioned that it is necessary to increase children's outdoor activities and advocate increasing outdoor sports in open, ventilated and indensed places, which is conducive to the prevention of myopia.

This is not contradictory to epidemic prevention and control, but it is necessary to do a good job in prevention and control.

There are several aspects to pay attention to. First of all, children should minimize close contact with others when they are outdoors, avoid crowding, and wear masks when they need to communicate with other children or others. Second, when children are outdoors, especially young children, they should be outdoors in the company of adults.

At the same time, parents should pay attention to children's hygiene, especially hand hygiene. Be sure not to touch the mouth, nose and mouth with your hands. Third, children should not spit when exercising outdoors, and should cover their mouth and nose with tissues and elbows when sneezing and coughing.

Fourth, take off your coat and wash your hands in time after returning home from outdoor sports, and in the case of such safety measures, it is very advantageous for children to be outdoors.

Studies have proven that outdoor light has a definite effect on the prevention of myopia. In particular, preschool children should increase the number of activities outside the household and insist on 1-2 hours a day to help prevent the occurrence of myopia. Increasing children's outdoor activity time can directly reduce the time students spend using electronic products, and it is said that it can also increase the secretion of dopamine in the body, which can effectively prevent the development of myopia.

Therefore, on weekends, take your children to climb, go on outings, ride bicycles, etc., encourage children to play various ball games, and cultivate hobbies such as skipping rope, gymnastics, dancing, and singing.

Outdoor natural light can better protect children's eyesight, because the outdoor natural light is not particularly dim or particularly bright, this kind of light will be better than indoor lighting.

Outdoor natural light can relieve the fatigue of the eyes, make the pupils narrow, not so blurry when seeing, and also allow the body to secrete some dopamine, slow down the growth of the high axis of hail, and prevent myopia.

Outdoor natural light can make people secrete some dopamine, slow down the growth of the eye axis, narrow the pupils, increase the depth of field or hall depth, reduce the mold of the eyes, and at the same time, outdoor natural light can also relieve eye fatigue.

A large amount of sunlight irradiates the secretion of dopamine in the body, which may slow down the growth of the eye axis and play a certain role in the prevention and control of myopia. Outdoor natural light is more illuminated than indoors, and strong light irradiation narrows the pupils, which deepens the depth of field and reduces blur.
