May is exciting with the refreshing scent of early summer, but I'm worried about the news that the rainy season will start earlier than usual all over the country. When it rains for a long time, you might think that UV protection will be a break, but in fact, it is said that the peak of UV rays is from May to August. The rainy season is also the same as midsummer, so it's a great enemy to be careless! This time, we will introduce the "sunburn mechanism" and "UV protection" that you should know now.

Wearing sunglasses on your skin is a sunburn!?

Do you know what mechanism causes sunburn? When UV rays pass through the skin and enter the body, active oxygen is generated in cells, damaging cells and DNA and promoting oxidation (aging). Therefore, in order to protect cells, the skin creates black melanin pigment when this active oxygen occurs and blocks it from damage. It can be said that the fact that the skin turns black means that the skin is creating sunglasses by itself to protect itself. This is the mechanism by which melanin darkens the skin. In other words, it is important to prevent UV rays from the outside and increase the antioxidant power in the body as a sunburn countermeasure.

What is the difference between UV-A and UV-B? Know the difference and take effective UV care.

We all know that UV exposure damages the skin, but there are different types of UV rays, and they affect the skin differently. "Ultraviolet rays (UV)" are divided into three types, "UV-A", "UV-B", and "UV-C", in order of wavelength. Of these, UV-C, which has the shortest wavelength, is the most harmful to the human body, but because it is absorbed by the ozone layer, it does not reach the ground. Therefore, we are exposed to two types of ultraviolet rays, "UV-A" and "UV-B", on a daily basis. Most of the causes of sunburn are "UV-B", and the skin affected by "UV-B" produces melanin, causing spots and freckles. "UV-A" has a weaker effect on the human body than "UV-B", but it has the property of penetrating clouds and glass, and without knowing it, it damages the skin and causes wrinkles and sagging. becomes. Therefore, be careful indoors even during the rainy season! According to data from the Japan Meteorological Agency, the amount of ultraviolet rays is about 80-90% when it's cloudy and about 30% when it's raining, compared to when it's sunny. On the other hand, however, it states that in cloudy weather, more ultraviolet light may be observed than in clear skies due to the addition of scattered light from clouds. In order to prevent accidental sunburn during the rainy season, it is necessary to take measures against UV rays regardless of the weather. Ultraviolet rays are often taken up as harmful effects, but ultraviolet rays are necessary for the production of vitamin D. Moderate going out is important. I want to face the sun positively while devising how to apply sunscreen and taking in nutrients frequently!
