Which city in China has the weakest ultraviolet rays in summer? I m so photophobic!

It is stronger in the south and northwest, and weaker in the northeast.

Xia Gan (Liang Heng).

Filling the summer is a tense, hot, hurried melody.

It was as if a pot of water on the stove was gradually bubbling and steaming until it finally boiled. The fine grass on the hillside gradually grew into a dense thick hair, and the faint green smoke on the forest belt also condensed into a long wall of dark colors. The butterflies are gone, but they are replaced by annoying cicadas and a long chirp among the leaves.

The fiery red sun baked a golden earth, and the waves of wheat rolled, beating the distant mountains, the clouds in the sky, and the cars on the road, like the waves of the sea surging on ships. Gold reigns supreme in the world, and the hot wind floats across the fields, blowing the aroma of ripe wheat. After half a year of accumulation, the spirit of spring has become a majestic momentum, rolling on the fields and rising between heaven and earth.

Summer is here. The colors of summer are golden. From a painter's point of view, there is some truth to this. The color of spring is cold green, such as blue waves, such as tender bamboo, full of hope; The color of autumn is hot red, like the sunset, like red leaves, marking the ultimate of things.

Summer is just between spring and autumn, and naturally responds to this neutral color - the harvest has been there and the hope is not over, it is a peak season of succession and succession, and life alternates.

You see, the wheat has just been cut, and the cotton seedlings in the fields with seven or eight green leaves, the sorghum and corn holding the trumpets in the sky, and the melon seedlings crawling forward on the ground are all bursting with vigorous vitality. At this time, they are no longer growing slowly in the spring breeze and light rain, but under the steaming of the summer, they are vigorous and vigorous, making the final sprint to the end of autumn.

The melody of summer is tense, and every nerve of people is tense. You see the sickle-wielding peasants in the fields, bent over, sweating, just thinking about quick cutting, quick cutting; Maizi came on the field, and thought about it again, and he wanted to fight, fight. It is hard enough for them to get up early and go to bed late, and they wake up in the middle of the night to listen to the window paper, but the wind blows; Look out the window, the sky is covered with clouds.

When the wheat is finished, it is time to breathe a sigh of relief, and we must hurry to top dressing and watering the autumn seedlings. "The Tian family has few idle months, and the people are busy in May", they carry the summer and autumn seasons on their shoulders.

It is a pity that the literati of the past dynasties do not know how many spring flowers and autumn moons have written, but there are very few shadows of summer. Probably the spring is melting, the autumn waves are surging, and the summer is always soaked in bitter sweat. People who have leisure and leisure naturally don't like this tense melody.

I want to praise this golden summer between spring and autumn.

Top 10 UV Weak Countries USA, Canada, UK,Sweden, Finland, Australia, Russia, etc. The country with the weakest UV rays in the world is Finland. Finland is located between 60 and 70 degrees north latitude, in the north of Europe, and a quarter of the country is in the Arctic Circle.

Within. UV index.

It refers to the degree of possible damage to the human body caused by ultraviolet radiation in the sun's rays that reach the earth's surface when the position of the sun is at its highest in the sky, generally around noon, that is, from 10 a.m. to 3 p.m.

The dangers of ultraviolet rays

In recent years, due to the stratosphere.

The increasing destruction of ozone and the increase in the amount of ultraviolet radiation received by the ground have caused widespread concern. For this reason, environmental scientists around the world have reminded people to pay close attention to the dangers of ultraviolet radiation to the human body and take necessary precautions.

When ** is exposed to ultraviolet light, the human body epidermal layer of the black tardin cells.

Begins to produce melanin to absorb ultraviolet rays to prevent damage to **. Prolonged exposure to ultraviolet rays can cause large amounts of melanin to be deposited in the epidermis, becoming permanent tanning marks.

Lhasa, Urumqi and other cities, Yunnan, Guangxi, Guizhou and other provincesUltraviolet raysComparatively stronger.

Sun exposure will cause photoaging, resulting in dark spots and freckles.

Wait a minute. Sunscreen products can effectively resist the damage of ultraviolet UVA and UVB. To find out how long sunscreen protects you, you should first know that you are not using sunscreen at all.

How long do you need to stay in the sun before your ** will turn slightly reddish; Then multiply the required time by the SPF value to get the protection time of the sunscreen.

Although SPF is an important indicator of sun protection, it does not indicate an SPF value.

The higher it is, the more protective it is. For example, SPF15 has 93% of the protective ability, while SPF34 has only 97% of the protective ability, but the larger the SPF value, the worse its permeability, which will hinder the normal secretion and respiration of **.

Exterior sun protection:

1. Keep away from strong ultraviolet rays. At noon, stay away from the sun, and from 10 a.m. to 2 p.m., the sun's ultraviolet rays are caught in the atmosphere.

The rate of filtration is minimal, so the intensity of UV rays is the strongest of the day.

Therefore, whether it is a school teacher or a parent, when planning outdoor activities for children, it is best to avoid this time, and adults should also avoid going out during this time.

2. Choose sunscreen.

SPF and PA. Generally, in the morning and evening of summer, rainy days, products with an SPF index lower than 8 are sufficient; Under moderate sunlight exposure, an index of 8 to 15 is better; In the anterior nucleus under strong direct sunlight, the index should be greater than 15. In addition to the SPF index, we should also pay attention to the PA that can block the skin from tanning, and generally choose PA++.

3. Use sunscreen correctly. Apply sunscreen ten minutes before going outside and reach a volume of 2 mg per square centimeter for best results. Clean** before using sunscreen; If it's dry**, apply a little lotion.

When applying sunscreen, don't neglect areas such as your neck, chin, and ears.
