Why does outdoor exercise help slow the progression of myopia?

Now we often hear that taking children to outdoor sports more often is good for myopia prevention and control. Why is this? Let's talk about it today!

A large number of studies have shown that sunlight promotes the secretion of dopamine in the brain , and dopamine has a certain inhibitory effect on the growth of the eye axis. Therefore, outdoor activities are a very effective and economical means of preventing and controlling myopia. It is generally recommended that children spend at least 2 hours outdoors every day, and young children can increase it to 3 hours. The activity location should have sufficient visual breadth and sufficient light coverage. The content, method and intensity of the activity are not the most important.

01 Are there any time period requirements for outdoor activities?

The correct outdoor environment requires plenty of sunshine, but be careful not to overexpose yourself to the sun. Be careful to avoid strong ultraviolet rays to prevent sunburn. You can sit in the shade of a tree in the morning when it is not so hot, or in the afternoon to cool off . The effect is not good in the evening or at night, remember!

02 How long is enough for outdoor activities?

To be truly effective, outdoor activities require at least 2 hours a day (the more the better). If it is less than 2 hours, the effect will be greatly reduced.

03 Should outdoor activities be carried out continuously or in batches?

Splitting it up is more effective than doing it for a whole period of time, but remember to ensure that the total time of outdoor activities is more than 2 hours a day and more than 14 hours a week.

Activities that require close eye use outdoors should be avoided as much as possible, such as reading under the shade of trees, digging in the sand, watching ants, etc. It is not completely useless, but the effect will not be very good. Everyone has already spent time outdoors, so the eyes should be relaxed to the greatest extent possible.
