Sunbathing for any age brings benefits to the body. Especially for babies and young children who are rarely exposed to sunny environments, sunbathing is very necessary. Some benefits can be mentioned of sunbathing such as:
Synthesize the amount of vitamin D needed by the body Vitamin D plays a very important role in the absorption of calcium by the body, helping children have strong bones. In addition, vitamin D has also been shown to have an impact on the neuromuscular system, maintaining stable insulin hormone levels to prevent type 2 diabetes, cancer, cardiovascular disease, infections caused by Vitamin D affects the production of antibodies, autoimmune diseases.
In the sun, there are types of rays that cannot be seen with the naked eye, which are UV rays, in which UVB rays have the function of helping the body synthesize vitamin D. Sunbathing is a measure to help the skin to come into direct contact with UV rays, Under the influence of UV rays, our body can synthesize vitamin D on its own.
Improve jaundice in babies Jaundice in newborns is usually a normal physiological manifestation due to a change in the type of Hemoglobin in the body. fetal blood after birth. Most of these cases go away on their own after a few days. However, for some cases of low birth weight, premature babies... can progress to prolonged jaundice or more severe levels. If severe cases of jaundice are not treated promptly or have the right treatment, it can cause many unpredictable consequences.
Sunbathing your baby will help improve mild jaundice and prevent severe jaundice. Because the blue light of the sun is very effective in reducing the concentration of Bilirubin accumulated in the subcutaneous fat layer in the child's body, which is the main cause of jaundice.
Increase levels of the hormone serotonin Low levels of serotonin in the blood can give rise to emotional problems such as anger, depression... Besides, serotonin also helps regulate sleep and digestion. .

Proper sunbathing not only makes the child's body healthier, but also minimizes the risk of harmful effects of UV rays on the child's body.
In sunlight, there are 3 types of UV rays including UVA, UVB and UVC, in which UVC rays have the greatest risk of damaging the skin, but are almost absorbed by the ozone layer. And UVA rays can penetrate clouds, ozone layer, clothing, glasses to affect the body and cause skin aging, but it does not have the effect of stimulating vitamin D3 precursors on the skin. Only UVB rays have the effect of helping the body synthesize vitamin D for the body, but unlike UVA rays, UVB rays cannot penetrate layers such as clouds, clothing, glasses, water...
Thus, for the purpose The main reason of sun exposure to help children synthesize vitamin D, we do not expose it through the window. Because UVB rays cannot penetrate the glass window, they will not synthesize the necessary amount of vitamins, but UVA rays can penetrate and adversely affect the delicate skin of children. In addition, it is also advisable to expose children's skin to partial direct sunlight because UVB rays cannot penetrate clothing.
Children's skin is very thin, much thinner than adults, so any UV rays can have a great effect on children. Therefore, children should not be sunbathing for a long time and sunbathing late to avoid affecting the baby's body.
