Health is a far-reaching topic, because few people are completely healthy, and most of them will get some diseases, so health can only refer to a certain stage of people, and sometimes our casual behavior will endanger our health. The following is a question about whether the skin is properly exposed to the sun.
Is it appropriate for the skin to bask in the sun? 1 Sunbathing can help people get calcium and vitamin D, and ultraviolet rays can be converted into vitamin D, which can help people absorb calcium and phosphorus. Sunbathing can also promote human blood circulation and enhance human metabolism.
It can also improve male androgen level and enhance sexual desire. Chinese medicine says that drying the back can strengthen yang. Proper sun exposure can also prevent skin diseases and enhance skin resistance. Sunbathing is easy to get skin cancer and melanoma, so you can sunbathe properly and don't expose your skin to the sun for a long time.
Sunbathing is good for your skin, but you need to control your time and not sunbathe for a long time. The sun contains ultraviolet rays. Proper sun exposure can promote the absorption of calcium in the body, which is beneficial to the body.
If you stay in the sun for a long time, it may lead to sunburn or melanosis, which will affect your skin health. Generally, it needs to be controlled at 10 minutes to 20 minutes when sunbathing, which is good for both skin and body.
Sunbathing is good for our cardiovascular and cerebrovascular diseases. It can stimulate the body to secrete hormones to regulate and promote the secretion of adrenal hormones, making nerves excited and happy. warm oneself
Although it has something to do with skin diseases, I can treat skin diseases through reasonable sun exposure. Some people specialize in phototherapy, and also use ultraviolet waves to treat diseases. As long as this band is well controlled, it can also inhibit cancer genes and stimulate immune function, thus playing a role in treating diseases.
Friend or foe, the key depends on how you bask.
Since there are good and bad basking in the sun, how can it be healthy? The most important thing is to protect yourself from the sun. It's almost summer, and the sun will be poisoned again. Everyone should do a good job in sun protection, whether it is physical sun protection or sun protection, so as to avoid skin aging and be beneficial to skin health.
Sunshine is good for health. We can choose to sunbathe in the early morning, 7: 00 to 8: 00, or after 4: 00 pm, which can supplement the vitamin D in the body and is good for skin health. It is best to sunbathe for less than half an hour or an hour every day. Our culture pays attention to balance, and it is best to keep the two in a balanced state.
Is it appropriate for the skin to bask for 2 days? Advantages: promoting calcium absorption, reducing skin infection, preventing anemia, etc. Disadvantages: lead to solar dermatitis, pigmentation, skin burns, etc.
In terms of benefits:
1, promote the absorption of calcium: ultraviolet rays in the sun can help the human body to promote the absorption of vitamin D, and vitamin D can promote the absorption and utilization of calcium, thus reducing leg cramps and osteoporosis caused by calcium deficiency. Therefore, it can effectively prevent rickets and rickets in infants; It can also effectively prevent osteoporosis, rheumatoid arthritis and other bone diseases in middle-aged and elderly people.
2, reduce skin infection: proper exposure to ultraviolet rays can effectively kill bacteria on the skin surface, enhance the skin's resistance, thereby reducing the chance of skin infection.
3. Prevention of anemia: Ultraviolet rays in sunlight can stimulate bone marrow cells to make red blood cells, improve hematopoietic function and effectively prevent anemia.
Disadvantages are:
1, causing solar dermatitis: solar dermatitis is a common photosensitive skin disease, which is more common in spring and summer and often recurs. Treatment should be based on avoiding strong sunlight as much as possible, and paying attention to shading or applying sunscreen when going out.
2. Pigmentation: When ultraviolet rays in the sun act on the basal layer of the skin, the skin is in a state of self-protection, thus activating the activity of tyrosinase, and releasing melanin after oxidation, resulting in pigmentation such as freckles, sunburns and black spots on the skin epidermis.
3, skin burns: long-term exposure and high temperature can lead to skin burns.
Is proper sunbathing good for the skin? 1. Be sure to get more sunshine in winter.
In winter and March, the days in the northern hemisphere are too short, the sun is hidden, the cathode is full, the vegetation is withered, the insects are hidden, and all activities tend to stop, so as to hibernate to save energy and prepare for the coming spring. In winter, the days are short and the nights are long, and the sunshine is reduced. There is a folk saying that "the sun in winter is as precious as gold", so we should take the initiative to bask in the sun to maintain the balance of yin and yang in the human body.
Sunbathing in winter has many advantages. You can not only enjoy the warm sunshine, but also make people feel comfortable and relaxed. It can also replenish yang, promote the circulation of qi and blood, balance the camp and health, and reconcile emotions, which is of great benefit to the body. It can be said that sunbathing in winter is equivalent to the most natural health care product, which is suitable for men, women and children.
The sun is the foundation of life. After winter, the sun closes, and the yin between heaven and earth flourishes while the yang declines. Therefore, it is beneficial to strengthen yang and warm menstruation in winter. The ancients also attached great importance to basking in the sun in winter, thinking that they could dehumidify and stop the cold, dredge meridians and expose the body, and then qi and blood would merge and get sick.
Liezi told a story, saying that once upon a time, there was a Fu Tian in Song State, and he felt very comfortable in the sun without clothes in winter. I didn't know there was a huge building in the world.
I remember when I was a child in the village, during the winter slack season, the villagers liked to gather under the south wall to chat and bask in the sun. I also got together in it and felt very comfortable. Bai Juyi has a poem that says, "Sitting with your eyes closed is good for your skin. At first, it was like drinking alcohol mash, and it was like being stung by Su. External integration is smooth, and Chinese integration is one. If you forget where you are, your heart is empty. " Now I feel very comfortable thinking about it.
In winter and March, the cathode between heaven and earth is flourishing and the yang is declining. In the human body, it is easy to get cold and all kinds of pain, while in the spirit, it is easy to feel depressed and depressed. Fortunately, there is still sun in winter. The sun is the source of life, and any life on the earth exists directly or indirectly by using the sun. Therefore, frequent exposure to the sun can dispel cold and yin, and it can follow the sun, especially in the severe winter. If it is sunny, you might as well get more sunshine.
Second, the disadvantages of not basking in the sun
How about basking in the sun? It is certainly not good to be exposed to the sun for a long time in hot summer. But not getting enough sunshine will also affect your health. At present, during the COVID-19 epidemic, many people naturally ignored our body's demand for natural light.
An article in Reader's Digest magazine in 2020 pointed out that not getting enough sunshine will bring five negative effects to the body. Let's make a detailed analysis from the perspective of Chinese medicine.
(A) feel depressed, even depressed
Depression is often associated with insufficient light, because insufficient light will lead to a decrease in serotonin levels in the brain. Serotonin is serotonin, which can make us feel happy and happy, so if you get more sunshine, your personality may become more sunny.
From the analysis of traditional Chinese medicine, sunbathing can promote the heart yang. And the heart governs the gods, the heart contains the fire of the monarch, and the heart has yang, then the fire of the monarch is bright, and there will be no mental symptoms such as depression.
Life is very common, many people will appear listless, easily tired, even taciturn, depressed, inattentive, flustered and other discomfort like animals after hibernation, which is a sign of depression. The reason why these uncomfortable symptoms appear is that it is cold in winter, and many people like to stay indoors, resulting in too little sunshine.
Sweden, Finland, Norway and other Nordic countries have short sunshine hours in winter, but Yang Qi does not converge. In these countries, the incidence of depression increases significantly in winter. Looking at some countries near the equator, the incidence of depression is obviously low. The incidence of depression among residents in high latitudes is extremely high, which is positively related to too little sunlight exposure, because the Yang Can of the human body does not rise, leading to an anonymous fire; People living near the equator are happier, which is also related to sunlight.
Furthermore, people who are introverted, sensitive and emotionally fragile, as well as those who work indoors for a long time and seldom exercise outdoors, are often prone to depression or depression, which is related to the lack of sunlight, which leads to weak heart-yang.
It is recommended not to leave the sun at four o'clock a year. Especially in winter, when you take advantage of sunny weather to go outdoors, bask in the sun, climb mountains or visit parks, these are all beneficial to the spirit of the sun.
I made it clear in Weibo that getting more sunshine can prevent depression. Someone asked, although there is plenty of sunshine in high-latitude cold areas, there is basically no heat and the sun is not warm. Does this work? -I think it's effective. The sun not only provides us with heat, but also with light.
From the perspective of traditional Chinese medicine, heat is equivalent to fire, while light is fire. Phase fire can warm yang and dredge qi and blood, while opening fire needs light, which can dissipate the haze and calm the mind, and naturally it will not be depressed.
(b) Bone pain and joint discomfort
Exposure to the sun for too short a time can lead to vitamin D deficiency and produce symptoms like arthritis or fibromyalgia syndrome (chronic muscle pain and fatigue). The reason why bone health is related to sunlight is that the lack of vitamin D will interrupt the physiological metabolism process of building bones. Especially in autumn and winter, people are often reluctant to spend time on outdoor activities, so insufficient sunshine time will cause musculoskeletal pain.
From the analysis of traditional Chinese medicine, pain comes from the disharmony between qi and blood, and it hurts if it is unreasonable. However, the kidney governs the bone, and the pain of the bone comes from the failure of kidney qi, which leads to the qi and blood in the bone being blocked. What shall we do? Sunbathing is a way to promote qi and blood in bones.
Some people live in a dark house all the year round, and even the sun can't shine in the house all the year round. Such a house is not conducive to raising yang, and it is easy to get sick if you live for a long time. Especially in winter, if you can't bask in the sun for a long time, it is easy to have joint muscle pain.
At four o'clock in a year, it is often the time when the sunshine is the least in winter. It is cold in winter, which should be the cause of kidney, and it is most likely to cause bone pain in winter. It is recommended to bask in the sun on sunny days in winter, which can effectively prevent bone pain and is a very enjoyable thing.
It's best to stay quietly in the sun, close your eyes and concentrate on enjoying the warmth of the sun without worrying about chores.
The ancients called sunbathing "negative mystery", which means the warmth of the sun. The sun meridian on the back is the barrier of the human body, and there are also back Shu points of internal organs. If the back is warmed by the sun, the qi and blood are harmonious, and the internal organs are harmonious, healthy and comfortable, it can also prevent bone pain and joint discomfort. Sunbathing in winter has many benefits, which can be described as killing two birds with one stone. It's really a wonderful method, far better than seeking medical advice.
(3) The body becomes fat and it is easy to get sick.
Sunlight can not only promote the synthesis of vitamin D, but also promote the release of nitric oxide in the body, so that metabolism can proceed smoothly and overeating can be avoided. A study published in the journal Diabetes found that moderate exposure to ultraviolet light can slow down weight gain and resist diabetes.
Another study published in the journal Nature also confirmed that the weight gain may be due to the lack of sunshine, but the healthy sunshine duration and sunshine intensity range need more research to determine.
From the analysis of traditional Chinese medicine, obesity originates from yang deficiency, including spleen yang deficiency or kidney yang deficiency. Yang governs qi, and when qi is abundant, phlegm and turbidity cannot accumulate under the skin, so people will not be obese. On the other hand, if yang deficiency is not conducive to gasification, phlegm and turbid water will easily accumulate under the skin, leading to obesity. As the saying goes: ten fat people are nine virtual. How to prevent obesity? Of course, it is to support the yang and replenish the deficiency.
The sun is the source of yang, and sunbathing is the most convenient way to support and nourish yang. More sun exposure can rejuvenate the yang in the internal organs. If the yang is strong, it will be strong, not only to lose weight, but also to prevent obesity.
Why are there more and more fat people now? I analyze the reasons. In addition to too little exercise and overeating, most people living in cities now spend much less time in the sun, which leads to the following problems: lack of yang, weak gasification and easy obesity. And with lack of energy, limbs are prone to chills and depression.
On the contrary, getting more sunshine can not only make you energetic, warm and energetic, but also effectively prevent obesity.
Studies have shown that the distribution of obese people in China is gradually tightening from north to south, with more obese people in the north and less obese people in the south, and the northeast is the hardest hit area for obese people. We observe the average height of people all over the world. The closer we get to the equator, the shorter we get, and the higher we get to the north. By analyzing the reasons, it is found that sun exposure is easy to make yang diffuse outward, and cloudy turbidity is easy to be discharged, which makes people tend to be thin and less fat; Less sun exposure leads to restrained yang, and people tend to be taller and fatter.
We all have this experience in our lives. If we haven't basked in the sun for a long time, we will sneeze once we start basking in the sun. What's going on here? In fact, this is the body's response to dispelling cold and evil spirits. If there is accumulated cold in the body, sun exposure can stimulate the body's yang, which can drive away evil spirits with the help of the sun, so sneezing can drive away cold evil spirits.
The more you sneeze, the more you should bask in the sun. Therefore, if you just start catching a cold, you can actively stimulate the nasal cavity to sneeze a few times, which can quickly expel evil spirits. Moreover, it is also true that some people sneeze after drinking ginger, brown sugar, water or hot porridge.
(D) Poor sleep and lack of energy
If you stay in a closed room for a long time and don't touch a trace of natural light, we can get rid of the circadian rhythm and biological clock, but it also means that it will be difficult for you to go into deep sleep, and the quality of sleep will deteriorate and it will be easy to lose sleep. In addition, long-term expectation of using electronic screens under artificial light sources or for a long time will also lead to serious sleep problems.
Chinese medicine believes that people who do not bask in the sun are prone to insomnia. On the contrary, people who often bask in the sun are not prone to insomnia. For example, people who work outdoors for a long time are often not prone to insomnia, while those who work indoors are prone to insomnia. Yang can't get rest because of insomnia, which will cause mental deficiency.
The study found that working in an office with good natural light prolonged people's sleep time by an average of 37 minutes. With the passage of time, the positive effect of sunlight became more and more obvious, and the cognitive test scores of participants also increased by 42%. The test of the two groups of students also found that the class with large windows slept 36 minutes more on average than the class with ordinary windows. Because the sun is the source of life, more sunshine is definitely good for sleep.
What should we do if we have insomnia, or want to prevent insomnia, or want to improve our mental state? My suggestion is to get more sunshine.
Modern research has found that sunlight has an influence on the body's biological clock, which will remind the brain when to secrete cortisol and serotonin, so that the body can prepare for the day's activities; Prompt when melatonin is produced, which causes sleep.
Lack of sunlight can lead to a series of health problems, including a decline in sleep quality. Chinese medicine believes that sunbathing can make the human body strong and healthy, and make the circular movement of the human body bigger and rounder. The yang is not only high, but also heavy, which naturally contributes to sleep.
And sleep is the root of yang, and the spirit comes from yang. The deeper you sleep, the stronger your yang will rise and the more energetic you will be the next day.
(5) Increased sweating and easy fatigue.
Hyperhidrosis on forehead is one of the typical manifestations of vitamin D deficiency in the body without strenuous exercise and normal room temperature. The low level of vitamin D may be related to diabetes, osteoarthritis and even cancer.
From the analysis of traditional Chinese medicine, yang plus yin means sweat. People can sweat because of the balance of yin and yang. If sweating does not stop, it is due to too much yang added to yin, which leads to the continuous leakage of yin and body fluid. Sweat is yin and body fluid, and you will be exhausted when you sweat. If you sweat too much, you will get tired easily.
When will you sweat more? Or it is hot, sweating and cooling; Or when exercising, balance yin and yang by sweating. Furthermore, sweating occurs when you are nervous or frightened, that is, sweating is used to reconcile the camp and guard, balance the viscera and keep the viscera stable.
If you are not hot, exercise or nervous at ordinary times, but you keep sweating, this is yin-yang imbalance. What should we do? It is suggested to bask in the sun more and balance yin and yang through sunbathing. Because life is yang, and the sun is the source of life.
Sunbathing can nourish, warm and ventilate the yang, while Wang Yang has a powerful gasification function, which can produce yin and balance the yin and yang of the human body. This is what the ancient sages said: "Those who are good at nourishing yin must seek the yin in the yang, and then the yin rises above the yang and the spring is inexhaustible." It can be seen that the more people who are prone to sweating at ordinary times, the more they can't avoid the sun.
Summary:
It's winter. It is recommended to bask in the sun more in winter, which is both enjoyable and healthy. The sun is the source of our life. Heaven can't live without this fire, and people can't live without this fire. Ancient sages repeatedly stressed: "I am not tired of the sun" and "I will wait for the sun". As the saying goes, "the sun is a treasure, just bask in it often." Therefore, regular sun exposure is good for health.
As the saying goes, "It is better to drink ginseng chicken soup than to bask in the sun in winter", which greatly appreciates the benefits of sunbathing. Office workers face the computer every day, rarely see the sun, and endure the pressure of work. Yang spirit is not easy to spread, and their health will decline. If they can persist in sunbathing, it will help to improve their health.
Whether it is treating diseases or preserving health, it is inseparable from yang, which originates from the sun. I have repeatedly stressed that we should get more sunshine, because it can make the whole body yang unobstructed and is good for health.
According to the recommendations of the American Cancer Commission, you should be exposed to normal sunlight for 10 to 15 minutes every day.
