Sunbathing can supplement vitamin D, promote the absorption of calcium and strengthen the body. However, there is also a lot of learning under the sun. Sunbathing in different parts not only makes people feel most comfortable, but also keeps them healthy.
1, calcium supplementation and hair growth on the top of the head: the sunlight on the top of the head can fully promote the absorption of calcium. Many people like to wear hats when basking in the sun. In fact, the sun is not so strong in spring, and wearing thick clothes and a sun hat can't play the role of sunbathing at all. Especially for children, parents are afraid that the sun will burn their delicate skin, so they always wear hats for their children.
In fact, as long as you control the time and let your child's head bask in the sun, it is helpful for the development of the brain and the growth of the skull, and it is also good for the growth of hair.
2. Sun restores spleen and stomach harmony
? The front is yin, and the back is yang. Drying the back can play a role in tonifying yang. ? The weakness of yang will make people's hands and feet cold, and it is often accompanied by spleen and stomach discomfort, such as fear of stomach cold or diarrhea after eating cold things. Sunbathing the back in spring can dispel the cold of the spleen and stomach and help improve digestive function. In addition, doctors in the Qing dynasty once pointed out? The back is yang, and the heart and lungs govern it? Sun-drying the back can also dredge the back meridians, which is of great benefit to the heart and lungs.
3, weekly 10 hour to prevent myopia.
The intensity of outdoor light is more than 10 times that of indoor light. A number of studies in the United States, Singapore and other countries have found that the longer outdoor activities, the less likely children are to be nearsighted, and the two are highly correlated. A study shows that light must reach a certain intensity and duration to prevent myopia.
It is found that children spend 10~ 14 hours in outdoor activities every week, but children who only spend 3~6 hours in outdoor activities every week have no influence.
4. Dry your legs and don't cramp.
? Old cold legs? You should get out in the sun more often. Sun-drying the legs can dispel the cold in the legs, effectively relieve the cramps in the legs, accelerate the absorption of calcium in the legs, make the bones stronger and prevent osteoporosis. ? Especially for people with rheumatoid arthritis, sunbathing in spring can activate blood vessels, relieve the disease and play an auxiliary treatment role. In addition, there are many acupoints on the legs, which can make people feel relaxed and tired through the stimulation of sunlight.
5. Sunbathing for the elderly in spring is good for health and disease prevention.
1), the elderly bask in the back in spring, which can drive away the cold of the spleen and stomach and help improve digestive function. In addition, drying the back can also dredge the back meridians, which is of great benefit to the heart and lungs. Old people have less outdoor activities and insufficient ultraviolet rays. At this time, they need more sunshine. Because the right amount of ultraviolet rays can promote the absorption of calcium and help prevent osteoporosis and rickets.
2) Old cold legs should often come out to bask in the sun. Sun-drying the legs can dispel the cold in the legs, effectively relieve the cramps in the legs, accelerate the absorption of calcium in the legs, make the bones stronger and prevent osteoporosis. I suggest that there are two periods of the day that are most suitable for sunbathing. The first section is from 6 am to 10. At this time, the infrared ray is at the peak, and the ultraviolet ray is low, which makes people feel warm and soft, and can play the role of promoting blood circulation and removing blood stasis. The second stage is at 4-5 pm, when the A-beam of ultraviolet rays is prevalent, which can promote the absorption of calcium and phosphorus in the intestine, help to enhance physical fitness and promote normal calcification of bones.
3) For elderly patients with rheumatoid arthritis, sunbathing in spring can activate blood vessels, relieve the disease and play an auxiliary treatment role. In addition, there are many acupoints on the legs, which can make people feel relaxed and tired through the stimulation of sunlight. Remind the elderly to take off their hats and gloves when sunbathing, try to expose their skin and let the sun get in close contact with their skin. Sunbathing through the glass window is not effective. It is best to be outdoors or on a spacious balcony.
6. Sunbathing can also increase the chances of pregnancy.
Through the investigation of 657 pregnant women, it is found that most of them are pregnant in months with long sunshine.
In spring and summer, you can get enough vitamin D by walking in the sun for 15 minutes. In the slightly dark autumn and winter seasons, you need to take 400 ~ 600 international units of vitamin D supplements every day.
It is best to bask in the sun in the morning from 10 to 1 1. Because the ultraviolet rays in the sun are low during this period, it can make people feel warm and soft.
Note that people of different ages have different tolerance to sunlight, and the length of exposure to sunlight is also different. Infant consumption per time 15. About 30 minutes, young people 1? Two hours, 20 for the elderly? Thirty minutes.
