sunlight and sunbathing.
Direct sunlight contains ultraviolet rays that cause the formation of vitamin D directly in the skin. In general, children need to spend some time in the sun. But I will make three warnings. First, the time spent in the sun should increase very gradually to avoid burns, especially if the sun is hot and the sky is clean. Secondly, prolonged exposure to sunlight is unreasonable, even if tanning was gradually formed. Sunburn protects the body from excessive sun exposure. In other words, the body can not use more than a certain amount of sunlight. Long exposure to the sun can harm the skin. Thirdly, a sunburn is as dangerous as a heat stroke. When you put the child to sleep in a stroller, think about how long it will be in the sun, especially if the place is new, and the sun shines brightly.
In summer, the child's body can be exposed to the sun's rays if the weather is warm and the child weighs 4.5 kg. He is already fat enough not to freeze, if he is partially undressed in the fresh air. In cooler weather, you can bare only the legs. Do not rush your face open so that your eyes are accustomed to the bright light. Children get used to light in different ways. If you substitute the face with the sun, turn the child's head to the sun: then the eyebrows will protect the eyes.
In winter, if you want, you can organize sunbathing at the open window if the room is warm and does not blow on the child.
Start with two minutes and increase the duration gradually - for two minutes every day. Half the time, hold the child on his back, half on his stomach. I would not advise exposing a child to the sun for longer than 30-40 minutes, especially in summer. In warm weather, it is important that the child does not overheat during a sun bath. It is better to put the child on the mattress on the ground, where it's cool, and not in a closed stroller. If the child is flushed, he is hot.
If the sun is very hot, for example on the beach, the child all the time should be kept in the shade for the first day or two, and even then it can get too many scattered ultraviolet rays. A child who knows how to crawl and walk, on the beach and in another sunny place needs a hat to protect the head from the sun. Remember that the redness from the burn appears a few hours after the damage has already been caused.
