【May】

Even if the sun doesn't shine so strong,May is a month in which it's the strongest ultraviolet rays in the whole year.☀

While the sun's altitude is 30ﾟ in the winter solstice 冬至,its 78ﾟ in the summer solstice 夏至.The summer solstice is the longest day in a year,so the sun also shines right above us so much that its ultraviolet rays also become strong.☀

By the way,the summer solstice is 21 June, but its ultraviolet rays become relatively weak owing to the rainy season or many cloudy days in June or July.☀

In addition,the weather is so dry in May that its sunlight also reaches the earth enough.☀

It's said the ozone layer which protect us from the ultraviolet rays become thinner,the rays in may may be dangerous💀

It's said moderate being suntannd is healthy,but being too much suntannd isn't.To make matters worse,being much suntannd makes us have liver spots しみ,or fleckles.It sometimes causes skin cancer.💀
