What are the ailments that need to be avoided from the sun?

Diseases that cannot be exposed to the sun include photogenic ** disease, lupus erythematosus, albinism and other diseases. 1. Solar dermatitis: If you suffer from solar dermatitis or vegetative solar dermatitis, polymorphic sun eruption, etc., sunlight will cause allergic reactions or phototoxic reactions to the body, and symptoms or aggravation will occur after exposure to ultraviolet rays in the sun.

2. Lupus erythematosus: ultraviolet radiation will lead to the onset or aggravation of lupus erythematosus symptoms, manifested as **erythema, the original symptoms worsen after exposure to sunlight, and patients with severe conditions will lead to more complications. 3. Albinism:

Albinism is a hereditary disease caused by a lack of melanin in its appendages, and if the patient is not protected by melanin, they cannot be exposed to sunlight. If you are active in the sun, wear a sunhat or parasol, wear long sleeves and long pants, and avoid ultraviolet radiation**, which can aggravate the condition**.

In addition to visible light, there are also ultraviolet rays in sunlight, and the damage caused by ultraviolet rays to the skin is the most effective and cumulative among the exogenous aging factors buried in the eggplant. Solar ultraviolet rays can be divided into long-wave ultraviolet (UVA), medium-wave ultraviolet (UVB) and short-wave ultraviolet (UVC) according to the wavelength, and the longer the wavelength, the greater the harm to **. Short-wave ultraviolet (UVC) rays are normally absorbed by the ozone layer and rarely reach the ground.

In hot weather, the damage caused by not wearing sunscreen is mainly manifested as the problem caused by ultraviolet ultraviolet (UVA) and ultraviolet (UVB).

1. Long-wave ultraviolet (UVA) can lead to aging, such as wrinkles, blindness, roughness, sagging, weakened elasticity, pigmentation, etc.;

2. Medium-wave ultraviolet (UVB) can induce or exacerbate various light-related diseases, such as solar dermatitis, polymorphic light eruption, acne, facial dermatitis, and even cancer.

Therefore, sun protection is particularly important. General sunscreen methods include applying sunscreen products, using sunscreen clothing, hats, umbrellas, sunglasses and other items, and eating sunscreen foods. In addition to this, it should be avoided to avoid exposure to sunlight at the most intense time of day; Sunscreen is best applied 20-30 minutes before going out, and the amount should be enough to cover**, it is recommended to reapply it every 2 hours or so; Whether it's cloudy, rainy, or indoors, apply sunscreen as usual. If necessary, scientific skin care can be done with the help of medical aesthetic means.

The benefits of sun exposure to the human body are manifold. Basking in the sun on a sunny day in the cold season not only warms people, promotes blood circulation and metabolism, but also enhances the body's absorption of calcium and phosphorus, and has certain benefits for rickets, rheumatoid arthritis, and anemia patients to recover their health, especially for infant hypochondriasis. The ultraviolet rays in the sunlight have a strong bactericidal ability of the roller, and generally bacteria and some viruses will be killed after half an hour or several hours in the sun.

For example, Mycobacterium tuberculosis can survive for several months in a dark, damp environment, but only for a few hours in sunlight. In addition, ultraviolet rays can also turn dehydrocholesterol in the human body into vitamin D, which promotes bone calcification and growth, so sunlight also directly affects people's height. Excessive ultraviolet radiation will dull people's reactions, which can induce ** and lung diseases.

The reason why the "sunbathing" that prevailed in the West in the seventies and eighties of this century failed to continue to be popular all over the world is because in the process of sunbathing, it was exposed to the sun for a long time, which damaged the tissues and had adverse effects on health. Although it is not suitable to be exposed to the sun in the middle of summer, even in winter, the more sun is not as much as possible, you should choose the "** period" before 10 o'clock in the morning and after 3 o'clock in the afternoon, and insist on basking for 30 60 minutes every day. For the elderly and infirm, it is best to choose half an hour after sunrise as the start time of sunbathing, when the air is moist and fresh, and the sun is warm and soft.

1. Frequent exposure to the sun can promote VD synthesis and promote calcium absorption, which can prevent rickets in children and osteoporosis in the elderly 2. Exposure to the sun can prevent infection, promote the formation of melanin, and prevent vitiligo, purpura and fungal infections and other diseases 3. Long-term exposure to direct sunlight will be burned by the sun, infrared rays will heat the dermal tissue and cause damage to the dermis, and ultraviolet rays can easily lead to cancerous changes such as melanoma, so avoid direct sunlight when receiving sunlight, and use sunscreen to block ultraviolet rays.

1. Photoaging: The photoaging damage caused by ultraviolet radiation will have a great impact over time, such as premature aging, fine lines, pigmentation, enlarged pores, sagging and other problems. 2. Sunburn:

During the period when the light is relatively strong, **directly exposed to the sun, it is easy to have an inflammatory reaction due to ultraviolet damage**, that is, solar dermatitis, which is manifested as redness, swelling, peeling, blisters, accompanied by burning and stinging. 3. Aggravation of vitiligo: Sun exposure is the cause of aggravation of vitiligo, when the melanocytes are hyperactive after exposure, when the melanin intermediate substances are overproduced or agglomerated to damage the melanocytes, resulting in vitiligo.

4. Pigmentation: When it is difficult to block ultraviolet damage and the stratum corneum crystal that resists ultraviolet rays is destroyed, more melanin will be produced locally, and if the metabolic ability of the company is weak, sunspots will appear. 5. Turning black:

The sun will turn black, which is a common knowledge that many people know, because the irradiation of the ultraviolet chain will activate the tyrosinase activity in the **, resulting in a large amount of melanin production, making the ** black. How to properly protect yourself from the sun? In addition to applying safe and appropriate sunscreen for daily travel, we should also pay attention to "hard sun protection", such as using hats, umbrellas, clothing, sunglasses and masks.

In addition, travel will be reduced during the midday period. Remember to remove makeup even if you only wear sunscreen, otherwise it is easy to clog pores. Sunscreen should not be just a whim for everyone, but also not only in summer, if you want to slow down photoaging, photodamage, sunscreen should become a lifelong topic for everyone, if there is sunburn, white spots and other conditions should be timely to the regular hospital for treatment.

Basking in the sun is harmful to the sun, the sun contains ultraviolet rays, and long-term exposure to the sun will turn black, because the ultraviolet rays will shut down and make the paracutaneous melanin in our ** precipitate and turn black. UVA and UVB in ultraviolet rays can accelerate aging, burns, and if this is done for a long time, the risk of cancer increases.

Without sun protection, it is easy to get sunburn**, **allergies, melanin precipitation, etc.

1.If the skin is exposed to ultraviolet rays for a long time, it will cause the skin to become envious and dry, and at the same time, it will lead to the accumulation of melanin, thus forming a balanced sun spot.

2.Not wearing sunscreen can cause wrinkles to grow prematurely. After applying sunscreen, it can effectively block the sun's ultraviolet rays and form a protective barrier on the surface of the skin, but if you do not use sunscreen, it will cause problems such as dry lines and fine lines prematurely due to lack of moisture in the skin.

3.Not wearing sunscreen can make your skin irritated. The strong ultraviolet radiation reaches the dermis from the surface of the skin, causing serious damage to the skin, causing the skin to appear red, swelling, itching and other allergies.

4.Not wearing sunscreen can cause your skin to sunburn. Since moisture is an important nutrient for the skin, prolonged exposure to UV rays can accelerate the loss of moisture from the skin, resulting in dry and dehydrated skin, causing severe burns to the skin.

For example, it makes ** aging in advance, and there are fine lines, pigmentation, enlarged pores, sagging, and other problems. 2. Sunburn: During the period when the light is relatively strong, ** directly leaks into the sun, and it is easy to have an inflammatory reaction due to ultraviolet damage**, that is, solar dermatitis, which is manifested as redness, swelling, peeling, blisters, and burning and stinging.

3. Aggravation of vitiligo: Sun exposure is aggravated by vitiligo.

1. Washing the mu without sunscreen will lead to sunburn, and ultraviolet rays will make the *** inflammation state-resistant, redness, broken skin and even water digging.

First of all, it will tanize, and ultraviolet rays are also easy to accelerate the aging of the sun, making it sunburn.

Too much sun exposure and too much ultraviolet radiation can make people prone to cancer.

Long-term exposure to the sun is easy to cause photoallergic reactions, and ultraviolet rays of sunlight are still relatively easy to cause allergies, rashes or cancer. Frequent exposure to too much sun will cause aging, pigmentation and darkening, skin aging, mainly manifested in: dryness, loss of elasticity, and premature appearance of wrinkles.

It is best not to directly expose yourself to excessive sunlight. And Yu Zheng.

The best time to bask in the sun.

There are two phases to the best time to bask in the sun. The first stage is 9 a.m. to 10 a.m., during this period of time, the infrared rays of the sun prevail, and the ultraviolet rays are low, making people feel warm, comfortable and soft, which can play a role in promoting blood circulation and stasis and promoting metabolism. The second stage is 4 p.m. to 5 p.m., during these two time periods, the A beam in the ultraviolet rays prevails, which can promote blood circulation in the body, and can also promote the absorption of calcium and phosphorus in the intestines.

It doesn't take too long to bask in the sun, about half an hour, and 15-20 minutes a day can play a role in supplementing vitamin D.

Pay attention to the following 4 points when basking in the sun.

But many people don't know how to bask in the sun, and some people are afraid of tanning their faces, so they bask with their backs to the sun; Others bask in the shade of trees; There are also people who bask in the sun through the glass at home, but in fact, these are not scientific methods of basking in the sun. The following 4 things are beneficial when basking in the sun.

1.These foods should not be eaten before sun exposure.

It is not advisable to eat mustard greens, pickled cabbage, lettuce, snails, shrimps, crabs, mussels and other photosensitive foods before basking in the sun, so as not to cause photosensitive drug eruptions or solar dermatitis. Drink more water, eat more fruits and vegetables, and supplement vitamin C after sunburn, which can inhibit the production of melanin.

2.Sunlight should be in direct contact with **.

When basking in the sun, the sunlight should be in direct contact with the spring stove**, which can synthesize vitamin D by itself, which is conducive to the absorption of calcium. It's best around 10 a.m. and 4 p.m., and around 11-12 p.m. in the cold winter.
