In central provinces and cities, this index is common at a high risk of harm, especially on June 12 at an average level. The UV index in the southern provinces and cities has a high and very high risk of harm, except for Ho Chi Minh City and Can Tho on June 12, which has a moderate risk of harm. On June 11, the ultraviolet index of provinces and cities in the North was very high. Illustration: Tuan Duc/VNA On June 11, the ultraviolet index of provinces and cities in the North was very high. This index in Ha Long city (Quang Ninh province) is from 8.4 to 9.1, in Hai Phong city it is from 8.9 to 9.2 and the same harm is very high from 11 to 13 hours. UV radiation in Hanoi city is very high at 12 o’clock with the highest index of only 7.8. In the southern and central provinces and cities, the UV index reached high levels. Except for Ho Chi Minh City, UV radiation reaches 8.3 – 8.9 and is harmful at very high levels from 11 to 13 hours. According to the World Health Organization (WHO), the UV index of 8-10 will cause burns to the skin if exposed to the sun for about 25 minutes. This index is 11 or higher, the skin is at risk of burns if exposed to the sun for about 10 minutes without protection. And ultraviolet rays at 12 will be very dangerous to health. Ultraviolet radiation is a component of sunlight, in which ultraviolet A and B rays (UVA and UVB) can damage the DNA of skin cells. When exposed to too much sunlight, the skin will burn, dry, darken, lose elasticity, create wrinkles, accelerate aging and can cause skin cancer. In addition to affecting the skin, UV rays can also cause eye problems. Experts recommend that everyone needs to wear goggles to protect their eyes. When outdoors, people should wear sunglasses that block at least 99% of ultraviolet rays. Sunglasses can help prevent cataracts, as well as wrinkles around the eyes, and it’s best to ask your ophthalmologist for the right glasses. The hot sun brings with it harmful ultraviolet rays that will also be dangerous to the skin. Therefore, besides sun protection measures such as wearing clothes, wearing a wide-brimmed hat… people need to pay attention to apply sunscreen and should apply it every 3 hours to protect the skin.

Komorebi [木漏れ日] is a Japanese word that means “sunbeams through the leaves”. According to AD9 Architects, the word Komorebi has many special layers of meaning, which are difficult to describe in other languages. . Therefore, the meaning of this word Komorebi we can understand with many other special meanings. The purpose of the project is to create a stopover for tourists here, the rooms are designed with sufficient area, minimalist interior, pure space for accommodation needs. The overall function of the project emphasizes the applicability as well as the living habits for guests to experience. Komorebi project has an area of ​​150 m² located in the center of Da Lat city. Komorebi stands out in the middle of Da Lat city because the house has white tones throughout with many different shaped windows. When starting the conceptual work for the project, Architects AD9 Architects identified Komorebi as a subject and the surrounding context as the core element. The elements around are linked in the most natural way. Here, the main shapes and colors chosen by the architect are simply self-perceptions derived from the above concept. People and scenes revolve around things become connected and harmonious, ensuring the new existence of the work is balanced and inseparable from the actual context. The building was renovated from an old house on a high slope. True to the meaning of the work, when stepping inside, it is filled with light, like “sunbeams through the leaves”. Architects AD9 Architects use wooden doorways and slats to express the meaning of the building “sunbeams through the leaves”. The change in light effects, shadows cast through each time of the day are different expressions of vision and emotions for the experience that each individual is different, but the interesting thing is that. It is a system of windows and wooden slats that create conditions for sunlight to enter. White horizontal blinds make the house more airy, but still ensure privacy when needed. The wooden beams and doorways also create a shadow effect on the walls of the house, and at the same time create an interesting feeling for the footsteps when going upstairs. The transparent glass roof helps natural light spread throughout the indoor space. The rooms are designed with sufficient area, minimalist interior, pure space for accommodation needs. Many trees, colorful flowers create accents in the front of the building. The toilet has a simple design, with blue tiles creating a cool and pleasant feeling.

It is forecasted that from May 12-14, the UV index in all provinces and cities across the country is at a very high risk of harm, particularly in Ha Long city (May 12), Can Tho ( May 13-14), Ho Chi Minh City and Ca Mau (May 12-14) have a high risk of harm. According to the World Health Organization, the highest UV index is 11+ (too high) with a burn time of 10 minutes of continuous exposure; Index level 8-10 (very high) has a burn time of 25 minutes of continuous exposure. Ultraviolet radiation is a component of sunlight, in which ultraviolet rays A and B (UVA and UVB) can damage the DNA of skin cells. When exposed to too much sunlight, the skin will burn, dry, dull, lose elasticity, create wrinkles, accelerate aging and can cause skin cancer. In addition to its effects on the skin, ultraviolet rays can also cause eye problems. According to doctors, from 10-16 hours is the most intense sun, if not necessary, people should stay out of the street and when on the street should wear clothing that can protect the skin as much as possible, use a hat, hats cover the head, face … so wear a wide-brimmed hat that covers 2/3 of the face; use umbrellas, wear dark, black glasses, and seal the mask. People should choose thick, cross-woven, face-covered masks that are black and dark (90% sunscreen, light-colored masks only work against the sun by 60%). Blue medical masks are only dust-resistant, not sunscreen. In addition, people should use sun protection products with a sun protection factor (SPF) of 30 or more to protect the areas of the face, lips, arms, hands …, apply 15-20 minutes before Go out in the sun and reapply if you sweat a lot.

However, not everyone understands correctly about ultraviolet rays. Misunderstandings about ultraviolet rays can make you stay in the wrong way. Find out information about ultraviolet rays in the article below will help you have a better view of this ray as well as understand the best of ultraviolet rays. 1. What is ultraviolet rays? Ultraviolet or ultraviolet rays are also abbreviated as UV, from the English language is Ultraviolet. Ultraviolet rays are electromagnetic waves with shorter wavelengths to visible light but longer than X-rays. Ultraviolet rays can also be divided into near ultraviolet with wavelengths from 380 to 200 nm and far ultraviolet or vacuum ultraviolet with wavelengths from 200 to 10 nm. Specifically, when ultraviolet rays affect human health and the environment as follows: UVA rays, also known as long wave or black light, have a wavelength of 380-315 nm. UVB is also known as the average wavelength with a wavelength of 315-280 nm. UVC has a shorter wavelength of 280 nm and is also known as a short wavelength, or is sterile. 2. Understand correctly about ultraviolet rays In summer, the highest time of year ultraviolet rays appear because direct sunlight greatly affects the skin, eyes and human health. So what major myths do you often encounter in the summer about ultraviolet rays that affect your quality of life? 2.1. Subjects are more susceptible to exposure to UV rays Young people are more vulnerable to UV exposure. Research data shows that up to about 50% of people are exposed for life to ultraviolet rays before the age of 18. Young people are more often exposed to ultraviolet rays than young people spend more time outdoors than older people. In particular, young people under the age of 18 still do not fully understand the harmful effects of UV rays to their health, so they do not really pay attention to covering their skin, wearing a wide-brimmed hat or sunglasses to protect their eyes when going out in the sun. . Ultraviolet rays affect everyone if they do not protect the skin properly – Photo Internet 2.2. When do UV rays appear highest? It is known that the amount of UV rays in the sun will be the most from 10 am to 4 pm. This is also known as the time when the sun contains the most ultraviolet rays of the day affecting people. In addition, in Vietnam, ultraviolet rays are most active in the summer. Vietnam is a tropical country, ultraviolet rays are present in all seasons of the year but highest in the summer. 2.3. Effect of ultraviolet rays on the eyes like? Many people mistakenly believe that ultraviolet rays cause little effect on the eyes. In fact, the harmful effects of ultraviolet rays on the eyes often accumulate over time. In particular, many cases of harmful effects from ultraviolet rays to the eye once it has emerged can leave permanent consequences. 2.4. At what time does ultraviolet rays affect the eyes most strongly? Ultraviolet rays are most active from 10 a.m. to 4 p.m. It is wrong to assume that this is the time when ultraviolet rays have the strongest impact on the eyes. In fact, eyes and skin are not the same. The human eye tends to be most exposed to UV radiation in the early morning and late afternoon. This means that the eyes are exposed to ultraviolet rays before 10 a.m. and after 4 p.m. Read more: How are UV rays harmful to the eyes? How to protect eyes from the sun. 2.5. Wear sunglasses help protect against UV rays? Many people believe sunglasses can 100% protect eyes from UV rays. However, this is a misconception. In fact, not all sunglasses are created with the same process and quality. This shows that there are many types of sunglasses that do not provide the ability to protect the eyes from the harmful effects of UV rays. Especially the sunglasses sold on the market without brand. Research done confirms that up to 45% of ultraviolet rays can still reach the eye even when you wear glasses with UV protection. Therefore, experts make the mistake of choosing large sunglasses that surround the eyes and need to make sure that the sunglasses you use are effective in protecting the eyes from ultraviolet rays. In addition, glasses should be worn during outdoor activities. Absolutely not subjective because wearing sunglasses does not completely protect the eyes from UV rays as you think – Internet photo 2.6. Do you have ultraviolet rays in cloudy weather? Most people think that if the weather is cloudy, when it is not sunny, UV rays will not appear. In fact, more than 90% of the ultraviolet rays penetrate the clouds. And from there, ultraviolet rays affect your skin and eyes. For weather, even on cloudy days, UV rays have the ability to affect as well as affect human health. 2.7. Do not use sunscreen A lot of people, especially women, because they use so many lotions, take care of their skin before the sunscreen step. The types of products used can also protect against the sun, so it is completely wrong to not use additional sunscreen on your skin. Only do not use extra sunscreen when the cosmetics you use have a sun protection factor of SPF 30 or higher. If not, be sure to apply an extra layer of sunscreen after using other lotions. Note, should re-apply sunscreen every 2 hours when participating in outdoor activities for a long time. Not only that, cosmetologists also said that most cosmetics do not provide enough functions to protect the skin from the harmful effects of ultraviolet rays. Meanwhile, if there is sun protection effect, the cosmetics only have an SPF of lower than 30. : Instructions on how to use sunscreen effectively and properly Mistakes when applying sunscreen that many people make 2.8. Sitting in a car is not harmful to UV rays? One of the many misconceptions about ultraviolet rays people encounter. In fact, even though the car’s glass has the ability to reduce the radiation intensity. However, it is also not possible to completely prevent UV rays from causing. Therefore, the effects of sunlight can still affect the skin if sitting in a car without other skin protection measures. Ultraviolet rays cause skin cancer for all skin types, not excluding oily skin as people mistakenly believe – Internet photo 2.9. Ultraviolet rays do not cause skin cancer in oily skin It is believed that ultraviolet rays do not cause skin cancer in people with oily skin. In fact, any skin type can suffer permanent damage or skin cancer if regularly exposed to ultraviolet rays. Therefore, people with oily skin still need to apply appropriate skin protection measures to combat the harmful effects of ultraviolet rays. 2.10. Get more vitamin D by getting plenty of sun exposure Many scientific studies have shown that prolonged skin exposure in the sun not only does not increase the absorption of vitamin D but also increases the risk of leading to cancer or other skin damage. Although the sun has many effects on the skin and eyes. However, the sun still has certain effects on mental health and metabolism of the body.

Ultraviolet rays, also known as ultraviolet rays, are rays emitted by the sun whose wavelengths are shorter than visible light and longer than X rays, the wavelengths of UV rays from 10nm to 380nm. Related to human health and based on the UV wavelength are divided into 3 categories: UVA: Wavelength from 380 to 315 nm; UVB: Wavelengths from 315 to 280 nm: UVB rays stimulate the metabolism of Melanin (skin pigmentation), making the skin dark and dull; UVC: Wavelength In addition to the ultraviolet rays emitted by the sun, there are also artificial ultraviolet rays such as those emitted by welding machines, from devices such as computers, phones, and televisions. According to BS. Dang Bich Diep – Stem Cell Research and Application Department, Central Dermatology Hospital said, too much exposure to sunlight will cause sunburns, eye damage such as cataracts, skin aging, If prolonged exposure, accumulation may cause skin cancer. According to BS. Diep, the ultraviolet index or the UV index (ultraviolet rays) is a measure of the intensity of ultraviolet radiation from the sun at a particular place on a particular day. The publication of this index will help people protect against UV rays, as too much exposure to sunlight will cause sunburns, eye damage such as cataracts, skin aging, if prolonged exposure. Long accumulation can cause skin cancer. The most common acute harm to UV ears is sunburn from short-term overexposure, doctors say. In particular, when the peak heat is hot it can cause heatstroke or heatstroke, affecting health. Accumulated UV exposure, or frequent and prolonged exposure to high UV rays, can lead to premature skin aging, especially skin cancer. The time of day that UV rays most easily affect the skin range from 10 to 16 hours depending on the season and region. So, to determine the dangerous UV index by standing in the sun and observing your shadow, if the shade is shorter than the height, it corresponds to the high UV index, now should use sun protection measures. . What to do to limit ultraviolet rays? At this time of prolonged hot weather, BS. Diep recommends that people take proactive measures to protect their bodies from UV damage such as: limiting peak sun exposure (shadow observation rule). When going out in the sun, you need to ensure sun protection measures: use sunscreen (choose a broad spectrum sunscreen that is resistant to UVB (SPF), UVA (PA), (SPF) rays. 30 and above, PA +++) Sunscreen should be reapplied every 2 hours or after exposure to water to ensure skin protection. You can use a combined sunscreen to protect your skin, UV-protective eyeglasses, wear a hat, and sun-protective clothing. Besides, drink enough water, eat fresh fruits and vegetables.
