1, the benefits of sunbathing
(1) Prevention of myopia
A study by the Australian National University pointed out that lack of sunlight may be one of the causes of myopia. Researchers believe that sunlight can stimulate the production of dopamine, which helps to prevent the axial length of the eye from becoming longer, thus preventing the focus distortion of the light entering the eye when focusing. Therefore, more sunshine and outdoor activities can help bookworms reduce the risk of myopia.
(2) Reduce colds
A study by Yale University School of Medicine found that regular sun exposure can help reduce the harm of influenza virus and other common respiratory diseases. Researchers believe that maintaining a high level of vitamin D in the body can better prevent problems such as sore throat, common cold and stuffy nose. Compared with people who spend less time in the sun, people living in sunny areas are less likely to be infected with influenza virus.
(3) Blood vessels are healthier
According to a study published in the British Medical Journal, people with low levels of vitamin D are at greater risk of heart disease, heart failure and stroke.
Many studies have also confirmed that the number of patients with myocardial infarction will increase significantly in winter when ultraviolet rays are scarce. Proper sunlight will help vitamin D become more active, thus reducing inflammation in the body and being more conducive to blood vessel health.
(4) prolong the service life
Since 1980, Danish researchers have studied 4.4 million Danmai people for 26 years, and found that more sunshine can prolong their life. Inge Henshipp Clemmensen of the Danish Cancer Institute also believes that those who often bask in the sun go outdoors more often than those who always stay at home or in the office, which is also an important reason for good health.
(5) Improve hormone levels.
One of the cheapest natural viagra may be to get more sunshine. Researchers at Graz Medical University in Austria found that the level of testosterone in the body will change with the fluctuation of vitamin D content. After autumn every year, the levels of vitamin D and testosterone in human body will decrease synchronously, and will reach the lowest in March next year. This has little to do with sunbathers. According to the study, the daily 1 hour sunlight can increase the testosterone in the body by 69%.
(6) Reduce the risk of cancer.
A study by the University of San Diego in the United States shows that women living in low latitudes are generally less likely to develop ovarian cancer lesions than women living in high latitudes, because the former is exposed to sunlight for a long time, and the intake of vitamin D will be higher at this time, which will be more conducive to cancer prevention than the latter.
(7) Less depression
It is found that the secretion levels of adrenaline, thyroxine and gonad will increase under sufficient sunlight, thus effectively improving the negative psychology such as depression and mental depression. Liu Baofeng, a senior psychological counselor of China Mental Health Association, pointed out that in winter and rainy weather, many people suffer from insomnia, chest tightness and irritability. The reduction of sunshine time is one of the reasons for seasonal affective disorder.
(8) Enhance immunity
Yang Li, a professor at the Graduate School of China Academy of Traditional Chinese Medicine, said that sunbathing has the function of tonifying yang and benefiting qi. Traditional Chinese medicine has the theory of "collecting the essence of the sun", that is, collecting sunlight to produce the qi of clearing yang. The normal viscera function in the human body is supported by yang, and the disease resistance of the human body will be improved if the yang is sufficient. Righteousness is relative to exogenous evil. Sunbathing can strengthen the body and enhance immunity.
2. What are the benefits and ways of sunbathing?
Many people know that sunbathing is good for health, but not many people can say why. In fact, sunbathing has a lot of knowledge. Sunbathing in different parts not only makes people feel comfortable, but also has different health care functions.
1, sunbathing can help people get vitamin D.
This is also the main source of vitamin D in human body. Vitamin D is also called "sunshine vitamin". The source of vitamin D3 contained in human skin is made by obtaining ultraviolet rays from sunlight and converted into vitamin D, which can help the human body absorb calcium and phosphorus and make children's bones grow strong and strong. Can be used for preventing rickets and rickets in children. For adults, it can prevent osteoporosis and rheumatoid arthritis.
Sunbathing can prevent skin diseases.
Proper exposure of the skin to ultraviolet rays can effectively kill bacteria on the skin and increase the skin's resistance.
3. Sunbathing can also enhance human immune function and increase the vitality of phagocytes.
Ultraviolet rays in the sun have a strong bactericidal ability. Generally, bacteria and some viruses will be killed if they are exposed to the sun for half an hour or several hours.
4. Sunlight can also mediate people's life rhythm and psychology.
Sunbathing can promote blood circulation, enhance metabolism and regulate the central nervous system, thus making people feel relaxed and comfortable.
5. Ultraviolet rays in sunlight can also stimulate bone marrow to make red blood cells and improve hematopoietic function, thus preventing anemia.
3. The sun is also particular.
Methods 1: Sunbathing on the top of the head to supplement calcium for hair growth.

Sunlight overhead can fully promote the absorption of calcium.
Many people often like to wear hats when they are in the sun. In fact, the sunshine in spring is not so strong. Wearing thick clothes and a sun hat can't play a sunbathing role at all. If the weather is fine, you'd better take off your hat when you are in the sun.
Method 2: Sun the back, spleen and stomach.
Sunbathing the back in spring can dispel the cold of the spleen and stomach and help improve digestive function. In addition, in the Qing Dynasty, it was pointed out that "the back is yang, and the heart and lungs govern it", and drying the back can also dredge the back meridians, which is of great benefit to the heart and lungs.
4. Other back care methods
Clothes to protect your back: Wear clothes to keep warm at ordinary times, and add or subtract to protect your back at any time.
Pay attention to avoid cold: the back will be touched by the five internal organs and Shu points, especially when it is hot and sweaty. If it is blown by the wind, cold and pathogenic factors will easily invade and cause disease.
Back thumping: Back thumping is divided into self-thumping and others thumping. This method can relax channels and promote blood circulation, strengthen yang and heart and kidney, and enhance human vitality.
Rub your back: rub your back and rub it with others. You can rub it yourself in the shower. Put a wet towel on your back, tighten both ends of the towel by hand and rub your back hard until your back is hot. You can usually rub your back with a dry towel. You shouldn't use too much force. The back rubbing method has the effect of preventing and treating colds, backache, chest tightness and abdominal distension.
Method 3: The longer the outdoor activities, the better for the eyes.
The intensity of outdoor light is more than 10 times that of indoor light. A number of studies in the United States and Singapore have found that the longer the outdoor activities, the better the eye protection. But in order to prevent the sun from hurting your eyes, you can't look directly at the sun when you are outdoors!
5. The benefits of children's eyes in the sun
Before the age of 6, children's eyes are prone to farsightedness; It is easy to cause myopia after 6 years old. The normal development of every child's vision needs the stimulation of natural light. Therefore, it is necessary for children's eyes to get proper sunlight.
Experts also reminded that it is extremely important to protect your eyes during your child's growth and development. While letting your eyes "bask" in the sun properly, you should pay attention to avoiding direct sunlight as much as possible and do proper protection and shading.
Method 4: Do not cramp and dry your legs.
"Old cold legs" should often come out to bask in the sun. Sun-drying legs can dispel the cold in the legs, effectively relieve leg cramps and accelerate the absorption of calcium in the legs. 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.
6. Do four things in the sun
1, the best time to bask in the sun
8 am to 10, and 4 pm to 7 pm is the best time to bask in the sun. At this time, the sunlight is mainly the beneficial ultraviolet A beam, which can make the human body produce vitamin D, thus enhancing the anti-tuberculosis and osteoporosis prevention ability of the human immune system and reducing the incidence of arteriosclerosis.
It's best to wear red clothes when basking in the sun.
Because the long-wave radiation of red clothes can quickly "eat" the short-wave ultraviolet rays with strong lethality, it is best not to wear black clothes.
3. Take off your hat and gloves when you are in the sun.
Expose the skin as much as possible, and let the sun be in close contact with the skin.
It is best to bask in the sun outdoors.
Sunbathing through the glass window is not effective. It is best to be outdoors or on a spacious balcony.
Conclusion: From the above, we can know that sunbathing still has so many benefits in our life, and it can also help us prevent diseases. If you want to have a healthy body, you might as well go out to contact nature and interact with the sun in your spare time.
7. How long can the baby bask in the sun?
It is best to control the baby to bask in the sun for half an hour to an hour in winter.
Some people think that the longer you stay in the sun, the better. In fact, it is enough to give the baby half an hour in winter. If you stay in the sun for a long time, you will sweat easily. If you take off your clothes, your baby will catch cold easily and your baby's skin will be very delicate. Staying in the sun for a long time can easily lead to sunburn, redness and even rapid pulse.
