Is it good to sunbathe in summer? When is the best time?

Is it good to sunbathe in the summer? When is the best time? My son is 2 years old. He doesn’t like to eat much, his hair is sparse, he is obviously shorter than other children of the same age, and he often grinds his teeth when he sleeps at night. My friend said that these symptoms of the child are due to calcium deficiency. If he doesn’t eat well, he can’t get enough nutrition. Sunbathing is a way to supplement calcium, but you must choose a good time period and avoid excessive exposure to the sun, which will damage the baby’s skin. My friend also told me when is the best time period for sunbathing.

Regular sun exposure can promote the formation of vitamin D in the body, and vitamin D can promote calcium absorption. But you should also be careful not to sunbathe for too long and avoid excessive exposure to the sun. The sun in the summer is often more poisonous, so you need to be more careful.

Infants and young children: once a day, early in the morning or late in the evening, each time for about 15 to 30 minutes. He Zhixin believes that babies' skin is delicate and easily burned, so you should choose a time when the sunlight is not strong and find a place away from direct sunlight. In Japan, when a baby is just one month old, parents will hold them and take them for a 20-30 minute walk outdoors every day. In spring and autumn, it is 9-11 am; in summer, it is before 9 am; in winter, it is around noon. After sunbathing, parents will wipe the sweat off their babies and give them water to drink.

Children: Avoid the sun between 12 noon and 4 pm. This is a critical period of physical growth and development, especially bone development requires a large amount of vitamin D to help the body absorb calcium. Vitamin D deficiency can cause slow growth in children. So, let your children play in the sun as much as possible.

Young and middle-aged people: 6-10 am and 4-6 pm, about 1-2 hours of sun exposure every day. People in this age group have a stronger metabolism and lose calcium faster, so they need to supplement more vitamin D. Therefore, if conditions permit, you should try to get more sun exposure.

Elderly people: twice a day, before 10 am and after 4 pm, 20-30 minutes each time. During these two time periods, the amount of ultraviolet A rays in the sunlight increases, which is a great time to store vitamin D in the body. For the elderly, getting adequate sunlight can help prevent and treat osteoporosis and depression. However, if exposed to too strong ultraviolet rays, it may also induce diseases such as dermatitis, cataracts, and age spots. In addition, elderly people with cataracts are advised to wear protective glasses to prevent ultraviolet rays from directly entering the eyes. He Zhixin also reminded that sunbathing should be done in moderation. Once it causes skin redness, peeling or rashes, you should stop.

You should choose the right time to sunbathe and be sure to avoid times when ultraviolet rays are strong. When sunbathing, be sure to take off your hat and gloves and expose your skin as much as possible.

The above is what my friend said about whether it is good to sunbathe in summer and what is the best time. My friend was very enthusiastic and introduced to me the time for sunbathing at different ages. We all understand that we can choose the time for sunbathing according to our age, but the intensity of the sun is different in each season, so we can adapt to the situation. Adjust it yourself.
