Can sunbathing improve the skin? There is plenty of sunshine in summer. When people go out for activities, if strong ultraviolet rays shine directly on the skin for a long time, it will cause skin damage, promote the formation of melanin, and make the skin appear spots and lose water. So can sunbathing improve your skin?

Can sunbathing improve the skin? 1 First of all, sunbathing can whiten the skin. Proper sun exposure will not cause erythema or discomfort. If the skin feels burning after sun exposure, it needs to be repaired immediately, indicating that there is too much sun exposure. Therefore, it is beneficial to bask in the sun properly, but it is necessary to master the time of sunbathing and avoid skin damage, such as applying sunscreen and wearing a sun hat before going out.

Secondly, we must choose a good time to bask in the sun, and it is best not to bask in the sun between 10 and 2 pm. During this period, ultraviolet rays are strong, and exposure to the sun will cause harm to the skin. In addition to sunbathing time, women should also do daily care. After sunbathing, cool down in time, rest for 15 minutes, and then take a warm bath.

Finally, after taking a shower, you can apply bitter gourd slices to your face, which can strengthen the protection of your skin. Eat more foods rich in vitamin C in your diet. For example, lemon contains a lot of vitamin C, which can effectively prevent and eliminate melanin deposition in the skin. Or cut the lemon into thin slices and put it in water to stir and drink. You can also eat some foods containing a lot of vitamins, such as tomatoes or cucumbers, which can not only replenish the water needed by the skin, but also whiten the skin.

In short, although sunbathing has whitening effect, it is necessary to master the degree. Especially after sunbathing, you should supplement vitamin C in time and drink plenty of water, so that your skin will recover faster. When playing outdoors, remember to apply sunscreen on your hands and feet, wear sunscreen clothes and a sunscreen cap, which can effectively resist ultraviolet radiation. However, whitening is not a day or two, and it takes a long time to see the effect.

1, sunbathing can promote the synthesis of vitamin D.

More sun exposure can supplement vitamin D. 90% of vitamin D needed by human body is synthesized by skin illumination. Vitamin D can promote the absorption of calcium and play a key role in bone health. This is also the main reason why doctors advise babies, teenagers and the elderly to get more sunshine.

2. Improve blood sugar and protect blood vessels.

Relevant research shows that proper sunlight exposure can enhance the sensitivity of insulin and reduce the level of triglycerides in the body, thus playing a role in preventing the risk of type 2 diabetes and cardiovascular and cerebrovascular diseases.

Studies have also shown that exposure to the sun can also lower blood pressure, which is related to the fact that nitric oxide in the skin can be absorbed by the blood when exposed to the sun, thus lowering blood pressure.

Step 3 improve your mood

As early as 20 years ago, The Lancet, a world-famous magazine, published relevant research, which showed that sunbathing can increase the turnover rate of serotonin in the brain, thus enhancing the sense of pleasure and happiness of the human body. In a bad mood, a little depressed? Might as well go out for a walk and bask in the sun, maybe your mood will get better.

Maybe it will make you smarter.

This is a study from the Chinese University of Science and Technology, which shows that ultraviolet rays can affect the central nervous system, and moderate B-band ultraviolet rays can enhance learning ability and memory.

Of course, there is still a lot of research on sunbathing, and the benefits of sunbathing are far more than that. For example, sunbathing can improve sleep, improve immunity, help to lose weight and prolong life.

Can sunbathing improve the skin? Why can sunlight be a good medicine to treat diseases?

Mainly because sunlight contains two kinds of light that are beneficial to health, ultraviolet and infrared. Ultraviolet is a kind of invisible light, which can not only kill bacteria on human skin, but also increase skin elasticity and enhance human resistance.

More importantly, after ultraviolet irradiation, "7- dehydrocholesterol" in human skin will be converted into vitamin D, which can enhance the absorption of calcium and protect the elasticity, luster and vitality of hair.

Infrared is also a kind of invisible light, accounting for 60% to 70% of sunlight. It can penetrate deep into subcutaneous tissue through skin, and has the functions of dilating blood vessels, accelerating blood circulation and promoting metabolism. At the same time, it also has anti-inflammatory and analgesic effects, and has a remarkable effect on hair care.

Is ultraviolet really harmful?

The saying that ultraviolet rays are harmful is widely circulated in contemporary times, and people have been blinded by the lies told by those who serve their own interests. In fact, most people who put forward this warning are practitioners in sun protection and medicine. In fact, sunshine is not only not fatal, but also a big project that gives us life and makes life survive.

Solar radiation has three kinds of visible light, infrared light and ultraviolet light. Because the wavelength of ultraviolet light is too short for human eyes to observe, most of the ultraviolet light is absorbed by the ozone layer, and a small part can reach the surface.

As mentioned earlier, ultraviolet rays have a very important influence on the normal function of the human body. Without ultraviolet radiation, our bodies will have a series of serious problems. As for diseases caused by sunlight, there is no evidence to support them.

Lack of sunlight can easily lead to many diseases.

In fact, there are countless diseases caused by lack of sunlight. Before the discovery of antibiotics in the 1930 s, sunlight was the most popular therapeutic energy, at least in Europe.

From the end of 19 to the middle of the 20th century, spotlight therapy was the most successful therapy for many natural therapists to fight infectious diseases. 1900 There was a famous doctor in Europe who opened 36 clinics at that time. His clinic used ultraviolet rays to treat many incurable diseases at that time, including tuberculosis, rickets, smallpox and lupus.

The results show that placing patients under controlled total sunshine has significant effects on lowering blood pressure, lowering blood cholesterol, inhibiting blood sugar and increasing white blood cells in diabetic patients.

Sunlight can increase the output of heartbeat and increase the oxygen content in blood. Gout, rheumatoid arthritis, colitis, arteriosclerosis, anemia, psoriasis, lupus erythematosus, asthma, acne and so on can all benefit from sunshine therapy.

Can sunbathing improve the skin? 1. Sunbathing can prolong life.

Modern research has found that when there is enough sunshine, the mortality rate is the lowest; The length of sunbathing is closely related to the life span. In a survey conducted by the World Health Organization, researchers obtained mortality data in different months in the northern and southern hemispheres and equatorial regions. Among them, the lowest mortality rate in the northern and southern hemispheres is in summer, and the equatorial region is relatively stable. The researchers speculate that this has something to do with sunlight.

In 20 13 years, the International Journal of Epidemiology studied 4.4 million Danes aged 0- 100 for 26 years, and found that more sun exposure can significantly prolong their life span. Even patients with skin cancer induced by excessive sun exposure have an average life expectancy of 6 years longer than that of ordinary people.

20 18 A 20-year study published in the journal Anti-Cancer Research also found that there is a strong inverse relationship between sunlight exposure and all-cause mortality: the more sunlight exposure, the lower the mortality rate.

Why sunbathing can prolong life? From the analysis of traditional Chinese medicine, because life depends on yang, Wang Yang is full of vitality, while yang deficiency reduces vitality. The sun is the source of the sun of life. More sunshine can make people's lives more energetic, and of course they can live longer.

Second, raise yang in spring and summer, and never leave the sun.

The sun shines in the sky, spring grows in summer, and autumn harvests in winter. People are endowed with the spirit of heaven and earth, and the four seasons are achieved, and people are also yang. If you want the sun to flourish, you can't do without the sun.

People need Yang. Where does Yang come from? One way is to bask in the sun directly. Especially before the arrival of the long summer in late autumn, more sunshine can satisfy the spirit of the sun and make people's sun spirit clear.

Neijing says: "Raise yang in spring and summer", how to raise yang? In spring and summer, the spirit of the sun grows and prospers. Raising the sun is to conform to the laws of natural change and enjoy the sunshine more. Sunbathing is the way the sun rises.

The way to keep in good health in spring is to raise yang. More sun exposure helps to generate yang. As the saying goes, "the sun is a treasure, just bask in it often."

In Neijing, it is said that Xia San keeps in good health every month, and "insatiable greed" is the key. In other words, don't be afraid of the hot weather, don't hide from the sun, go out to bask in the sun and sweat more. Some people think that the sun is too strong in summer and don't like to bask in the sun. We can bask in the sun more in the morning and evening of the day, so that the body can feel the existence of yang, thus automatically adjusting the balance of yin and yang in the body.

Third, get more sunshine when you are depressed.

From the analysis of traditional Chinese medicine, the sun provides us with vitality. The sun is yang, and yang takes the initiative, which can give birth to yang and cheer up the spirit. Especially in winter, you should get more sunshine. When the weather is cold, it is easy to cause insufficient hair growth due to yang.

Modern research also found that sufficient light can help our body to produce some specific neurotransmitters through the light stimulation of retinal ganglion cells, thus improving mood.

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. Studies in the United States have found that in sunny areas, the incidence of depression among residents is low. For example, in Florida in the south of the United States, there is plenty of sunshine, and 4% people show symptoms of depression; In Alaska, where the winter is long and the weather is gloomy, 28% of local people have depressive symptoms.

Studies have found that too little sun exposure will lead to an increase in melatonin secreted by the brain, which will aggravate the drowsiness and fatigue of the human body; At the same time, it can inhibit the production of "happy hormone" 5- hydroxytryptamine in the brain and promote depression. Clinically, seasonal depression caused by short days and long nights and reduced sunshine is very common.

The global disease burden survey conducted by the World Health Organization predicts that by 2020, depression will become the second largest disease after cardiovascular and cerebrovascular diseases. Depression seriously harms human health. We all want to prevent depression, and one way is to get more sunshine, which can make your mind clear and calm.

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, and light is just to ignite 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.

After winter, why is depression high? Because the yang is closed after winter, people's yang is not well developed, which easily leads to high incidence of depression. So be sure to get more sunshine, which will help prevent depression. There is really no sun, so come to the south.

Fourth, more sunshine can prolong sleep time.

The sun is the source of life, and more sunshine is good for sleep.

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.

How to avoid insomnia? It's good to get more sunshine. Studies have found that sunlight has an impact 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 yang circle of the human body bigger and rounder, which naturally contributes to sleep.

Five, the dog days bask in the sun and nourish the yang.

The dog days are the hottest time of the year. If you can bask in your back more during this time, you can not only cure diseases, but also cure serious illnesses.

The ancient book "Clinical Examination of Xiukunlun" said: "All male and female diseases, such as head wind, brain leakage, toothache, ear swelling, beriberi, scabies, pain in limbs, waist and back, wind cold, damp heat, weakness and soreness, can be cured and carved out from the roots in the hot noon sun and at the end of the dog days.

"The dog days are naked in the sun, sweating like a pig, and the air is cool, so I don't feel its heat. But the first sun will peel off, the thickness will follow its illness, and even blisters will appear. The sooner the less, two days, the real chemical industry. "
