The picture explains the eight benefits of sunbathing. Sunbathing can help the body remove most of the water. We can bask in the sun properly, but we can't always expose our skin to strong sunlight. The following are pictures about the eight benefits of sunbathing.
Eight benefits of sunbathing 1 1, promoting calcium absorption.
Sunbathing can help people get vitamin D, which is also the main source of vitamin D, also known as "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.
Step 2 prevent myopia
Less sunshine is one of the important factors of myopia. A study by the Australian National University pointed out that lack of sunlight may be one of the causes of myopia. Taking part in outdoor activities helps to reduce the risk of myopia.
Step 3 relieve depression
The occurrence of depression may be related to three factors, including biological factors, psychological factors and social factors, among which insufficient sunlight is an important biological factor. Experts believe that sunlight can promote the synthesis and secretion of neurotransmitters in the brain, making people feel happy. Sunbathing helps to relieve depression.
4. Improve immunity
Researchers at Georgetown University in the United States found that sunbathing can enhance immunity. The low-intensity blue light in sunlight helps to activate the hydrogen peroxide in the signal channel, and the immune cells T cells move quickly and remain vigilant to cope with the invasion of germs.
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.
6. Mediate the rhythm of human life
Sunshine also has a certain mediating effect on 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.
7. Improve male androgen level.
Sunbathing can improve male androgen level, enhance sexual desire and improve sperm quality. Because the testosterone level in human blood will increase with the increase of vitamin D content in the body. The study also confirmed once again that the daily sunshine of 1 hour can increase testosterone in human body by 69%.
8. Prevention of anemia
Ultraviolet rays in sunlight can also stimulate bone marrow to produce red blood cells and improve hematopoietic function, thus preventing anemia.
Precautions for sunbathing
Sunbathing has so many benefits, but you shouldn't be overexposed. Generally speaking, people with fair skin can meet the needs of making vitamin D by sunbathing 10~20 minutes 3~4 times a week. If you want to synthesize vitamin D artificially, you'd better choose to bask in the sun from 10 to 2 pm. When the weather is very hot, sunbathing for 5~ 10 minutes at a time is enough. Friendly reminder: if you sit in the sun in hot season, you must wear a sun hat. )
Need to be reminded that although sunbathing is good for physical and mental health, don't choose to sunbathe for nearly three or two hours at noon. Absorbing a small amount of sunlight can "nourish the body", make people healthy and energetic, and at the same time consume too much energy and worry about getting skin cancer. We should change with the seasons and decide how long it will take to get good results according to our own experience. And to synthesize vitamin D, you don't need to sunbathe naked, just wear short-sleeved shirts and shorts.
In addition, we should pay special attention to the fact that excessive exposure can easily turn human moles into melanoma or skin cancer. When in the sun, we must wear sunscreen clothes to cover the parts with moles.
It is best to wear red clothes in the sun, because the long-wave radiation of red clothes can quickly "eat" the short-wave ultraviolet rays with strong lethality, and it is best not to wear black clothes.
When basking in the sun, you should take off your hat and gloves, expose your skin as much as possible, and let the sun get in close contact with your skin.
Sunbathing through the glass window is not effective. It is best to be outdoors or on a spacious balcony.
Eight benefits of sunbathing Picture description 2 Eight benefits should be kept in mind.
1, myopia prevention
Lack of sunshine may be one of the causes of myopia. Sunlight can stimulate the production of dopamine, which helps to prevent the axial length of the eye from becoming longer, thus preventing the focus of light entering the eye from being distorted when focusing. Therefore, more sunshine and outdoor activities can help bookworms reduce the risk of myopia.
Step 2 reduce colds
Regular sun exposure helps to reduce the harm of influenza virus and other common respiratory diseases. 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
People with low levels of vitamin D have a higher risk of heart disease, heart failure and stroke. In winter, the number of patients with myocardial infarction will increase significantly.

4, prolong life
More sunshine can prolong life. People who often bask in the sun go outdoors more than those who always stay at home or in the office, which is also an important reason for their good health.
5, improve hormone levels
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. After daily sunshine 1 hour, testosterone in the body can increase by 69%.
6. Reduce the risk of cancer
Women living in low latitudes have a lower risk of ovarian cancer than women living in high latitudes, because the former has a long sun exposure and a high intake of vitamin D, which is more conducive to cancer prevention than the latter.
7. Less depression
Under sufficient sunshine, the secretion levels of adrenaline, thyroxine and gonad will be improved, thus effectively improving the negative psychology such as depression and mental depression. Many people suffer from insomnia, chest tightness and irritability in winter and rainy weather, and the reduction of sunshine time is one of the reasons for seasonal emotional disorder.
8. Enhance immunity
