Reasonable sun exposure for good health
The better our living conditions, the less we have intimate contact with the sun.
However, the growth of all things depends on the sun. The Yellow Emperor’s Canon of Internal Medicine said that “every tired of the sun” is telling us that sun exposure has great benefits.
Since the sky is beautiful in recent days and the sun is warm, why don’t we become a chance to bask in the sun and nourish our bodies.
First, the multiple benefits of sun exposure: 1.
Sun exposure helps the body obtain vitamin D. This is also the main source of vitamin D in the body.
Vitamin D is also called “sunshine vitamin”. The source of vitamin D3 contained in human skin is made by obtaining ultraviolet rays in the sun and converted into vitamin D. It can help the body absorb and absorb calcium and phosphorus, and make children’s bones strong.solid.
It has preventive effect on infant brass disease and rickets.
For adults, it has the effects of preventing osteoporosis and rheumatoid arthritis.
Vitamin D is considered both a vitamin vitamin and a hormone because it is one of the very few exceptions to vitamins.
The body’s vitamins cannot be synthesized by the human body, and must be replaced by food or pharmaceutical supplements, while vitamin D can be synthesized by the skin exposed to ultraviolet rays (direct sunlight is sufficient).
Vitamin D is mainly used to make up and maintain strong bones, especially to enhance the body’s ability to absorb calcium ions.
Exposure to the sun can prevent skin diseases. Proper skin exposure to ultraviolet rays can effectively kill bacteria on the skin and increase skin resistance.
Exposure to solar energy enhances the body’s immune function and increases the vitality of phagocytosing cells. Ultraviolet rays in sunlight have a strong sterilizing ability. Generally, bacteria and certain viruses are killed when exposed to sunlight for half an hour or several hours.
Looking at the green plants during the sun is also good for the eyes!
Especially friends who have been tired with eyes!
Sunlight can regulate the life rhythm of the human body and psychological exposure to the sun, which can promote human blood circulation, enhance human metabolism, and regulate the central nervous system, so that the human body feels stretched and comfortable.
Do you also experience changes in the weather and your mood? The most direct benefit of getting the sun is to make you happy.
Preventing anemia UV rays in the sun can also stimulate the bone marrow to make red blood cells, improve hematopoiesis, and thus prevent anemia.
Sun exposure can also increase the chances of conception. A survey of 657 pregnant women found that the majority of them were conceived during the months of reduced sunlight.
In spring and summer, just take a 15-minute stroll in unobstructed sunlight to get enough vitamin D; in the slightly dim autumn and winter, you need to replenish 400 a day?
Vitamin D supplements of 600 international units.
Old people can suffer from osteoporosis and mental depression when exposed to the sun. Studies have shown that sun exposure in the elderly can prevent osteoporosis and reduce the frequent depression of the elderly.
A geriatric expert at the Baltimore United Memorial Hospital in the United States has conducted a group comparison study of 244 elderly people over 65 years of age, and found that those who stay indoors for a long time and rarely go outdoors to receive sun exposure generally have symptoms of vitamin D deficiency.Mainly manifested as physical weakness, unresponsiveness and decreased bone mass.
The study also found that those who did not go out and often basked in the sun through glass windows also had symptoms of vitamin D deficiency.
The researchers explain that this is because the window glass filters out some of the ultraviolet light, which is essential for the body’s synthesis of vitamin D.
Therefore, in the winter, encouraging the elderly to go outdoors and bask in the sun and exercise their bodies will help prevent osteoporosis in the elderly.
The investigation has not found that in the middle of the winter season, the elderly are prone to mental depression, showing symptoms such as depression, fatigue, sluggish brain response and drowsiness.
Experts believe that in addition to the reduction in winter activity compared with other seasons, the important reason is that it is related to the short days and long nights in winter and insufficient light.
Because sunlight is an electromagnetic wave, it is like a natural “stimulant”.
Sunlight radiates to the human body and causes local physiological changes, such as the effect of infrared “heat”, which expands capillaries and accelerates blood circulation.
The effect of ultraviolet light can oxidize melanin, increase vitamin D and histamine in the skin, and increase gastric acid secretion.
It is also enough to increase blood hemoglobin, calcium, phosphorus, magnesium and so on.
In addition, sunlight in contact with nerve fibers through the eyes can promote the increase of adrenaline, thyroxine and gonadotropin.Adrenaline and thyroxine are hormones that evoke the work of human cells. When the content is relatively reduced, the cells will be in a state of inhibition, and the entire body function will be in a state of inhibition.
In winter, the intensity and time of light are relatively reduced. The elderly do not receive much sunlight, and often experience depression, depression, and mental fatigue, which are precisely related to the reduction of the above-mentioned hormone secretion levels.
Pregnant mothers are good for both mother and child. Too much winter sun for pregnant mothers has the following three benefits: A.
Reduce the risk of osteoporosis in pregnant women and reduce the incidence of rickets.
Due to the long winter in the north and insufficient sunshine, the incidence of congenital rickets in children is very high.
Nowadays, the disease also has a rising tendency in the south, which is mainly caused by pregnant women receiving too little sunlight and poor calcium awareness.
Therefore, Dongyang is the cheapest “tonic”. Pregnant mothers should bask in the sun in winter.
Sunlight helps pregnant women absorb calcium during pregnancy In order to ensure the normal development of bones and tooth germs during pregnancy, pregnant women must increase their calcium intake, and the absorption of calcium must absorb vitamin D in the human blood.
Only after ultraviolet radiation can the 7-dehydrogen free radicals in human skin become vitamin D3 and be absorbed into the blood by the body.
If not exposed to sunlight, the vitamin D in pregnant women will be deficient, and the absorption of calcium and phosphorus will be reduced, which will cause congenital rickets in babies born in the future.
Strengthen the resistance of pregnant women and prevent various infections.
Ultraviolet rays in the sun can kill pathogenic microorganisms.
Changyang Dongyang can also strengthen the resistance of pregnant women and prevent various infections.
Because the ultraviolet rays in the sun can kill pathogenic microorganisms.
Because ultraviolet rays can increase the reception of calcium, in addition to strengthening the strength of bones and muscles and improving cardiopulmonary efficacy, it can also strengthen the ciliary activities of the trachea and bronchi, and promote the clearing of respiratory secretions such as sputum, which is beneficial to respiratory breathingdispel.
In terms of enhancing the body’s immunity, calcium is a stimulator of serum regulators, which can accelerate the synthesis of human antibodies, induce and strengthen the phagocytosis of macrophages on pathogenic bacteria, and have a killing effect on pathogenic microorganisms that invade the body.
Prevent pregnant women’s mood swings and put an end to winter depression.
Changyang Dongyang is beneficial to avoid pregnant women’s emotional shake and eliminate winter depression.
During pregnancy, pregnant women are most likely to show emotional shake or emotional obstruction because of the effects of pregnancy and concerns about the well-being of the baby.
Winter is also a season of sexual affective disorder — the high incidence of depression in winter. This is due to the endocrine disorders caused by the large temperature difference between day and night in winter, so it is easy to present the disorder of emotions and vitality.
Sun exposure in winter with less sunshine is the best way for pregnant women with winter depression.
Second, the time of the sun is particular: but the sun is also particular about it.
In the winter, due to the weak contraction of the ozone layer and the strengthening of ultraviolet rays in sunlight, it is easy to cause different injuries to the human body.
Therefore, it is necessary to pay attention to scientific selection and scheduling in the winter.
According to scientific research, in the winter, three periods are more suitable for basking in the sun: The first stage is 6-9 am. During this period, the sun takes up the peak with warm and soft infrared rays, and the ultraviolet rays are relatively weak.
Infrared temperature is high, which mainly plays a warming role on the human body, accompanied by fever, promotes blood circulation and metabolism, and enhances human vitality.
· The second and third stages are 9-10 am and 4-5 pm respectively. The two periods of exposure are characterized by A-ray fragments in ultraviolet rays. At this time, the “sunlight vitamins”-vitamin D are stored in the body.Great time; at the same time, it can also promote the absorption of calcium and phosphorus in the body, enhance physical fitness, and help promote normal bone calcification.
Third, the baby’s attention to the sun: sunlight is the best vitamin D “activator”, after a cold and long winter, many mothers can’t wait to take the child to the sun to help the baby’s bones grow healthy.
In fact, basking in the sun is a science, you must choose the appropriate time and method.
Sun exposure is good for children’s bone growth.
It is appropriate from 6-10 am and 4-5 pm.
After choosing the right time, the child can often take out the sun after the full moon.
The time is preferably from 6 to 10 in the morning. At this time, the infrared rays in the sunlight are strong, and the ultraviolet rays are weak, which can promote metabolism. The ultraviolet rays in the ultraviolet rays are broken at 4-5 pm, which can promote the absorption of calcium and phosphorus and enhancePhysical fitness, promote normal calcification of bones.
What needs to be the best is that in any season, between 10 am and 4 pm, especially between noon and 4 pm, it is best to avoid continuous sunlight, because the ultraviolet rays in the incident sunlight are the strongest and cause skin damage.
The length of each sun exposure depends on the age of the baby, and it should be gradually increased, sometimes it is appropriate to gradually increase to 1-2 hours in a few minutes.
Or 15-30 minutes each time, several times a day. If you find that your baby’s skin turns red, sweats too much, and her pulse speeds up, you should go home immediately and give a cool drink or saline, or wipe your baby with warm water.
You can also bask for a while and rest in the shade.
Do n’t wear your baby too much. When some mothers take the baby in the sun, they are afraid of the cold. Wear hats, gloves and masks on the baby. It is not known that this type of sun is difficult to achieve, because the ultraviolet rays in the spring sun are weaker than in the summerMuch more, it is difficult for ultraviolet rays to penetrate the skin and reach the skin.
The baby should be exposed to the skin according to the high temperature conditions at the time.
In addition, clothing that is too thick and easy to sweat in the sun, sweating after the wind is easy to catch a cold.
Pay attention to avoid direct sunlight on the head, and do not expose the sun through the glass.
Some mothers are afraid of the baby’s hair dryer. They often let the baby bask in the sun through the glass. Didn’t they know that ultraviolet rays have a weak ability to penetrate the glass, and most of the ultraviolet rays are blocked out, thus reducing the effectiveness of the sun.
Do not take a bath before sunbathing. It is not advisable to fast your stomach when you are in the sun. It is best not to bathe your baby.
Because in the bath, the material “7-dehydrocholesterol”, which synthesizes active vitamin D in human skin, can be washed away, which reduces the role of promoting calcium absorption in the human body.
Don’t bask in the sun through the glass Some parents don’t understand the great effect of the sun on their children’s physical health, or they are afraid that they will feel cold while exposing them.Sun drying “Dongyang” on glass is actually extremely harmful.
First of all, children’s tolerance to the cold needs a process of exercise to improve their cold tolerance.
Sunny days are the first choice for children to take a cold air bath, because the temperature is relatively high at this time.
In fact, modern medicine has proven that the sun is the best supplement for your child’s physical health.
Changyang Dongyang can increase the content of vitamin D in children’s blood and prevent the decline of body resistance caused by calcium deficiency.
Children with low calcium are prone to various infections, especially pediatric pneumonia.
This is because calcium affects children’s resistance to some extent.
Studies have shown that calcium can effectively increase the phagocytic activity of phagocytes in human blood, accelerate the transformation of lymphocytes, activate the body’s complement system, and participate in the “fight” to kill pathogenic microorganisms.
In itself, calcium, as a basic ion, can regulate the acid-base balance of the body.
In the diet structure of modern people, the human body is often in an acidic environment, and the immune function of the human body is suppressed in such an environment.
Since the intensity of ultraviolet rays in the sun is not strong, and it can also be blocked by glass, clothes, dust, smoke, etc., the sun should try to make the skin directly contact the sun, and do not sun through the glass.
Fourth, the warmth of the sun tips: 1.
It is best to wear red clothing when you are in the sun, because the long-wave radiation of red clothing can quickly “eat” the short-wave UV rays that are very lethal. It is best not to wear black clothing.
When you are in the sun, you should take off your hat and gloves, and try to expose the skin as much as possible, so that the sun is in close contact with the skin.
If the sun is exposed through glass windows, it will not be effective.
It is best to be outdoors or on a spacious balcony.
