Hu Yajun, director of the Reproductive Medicine Center of Wuhan First Hospital: "During the examination, we found that she was a very homely woman, thin and weak, and she did not like to exercise. The examination found that her vitamin D level was very low, only about a dozen micrograms per liter, and it was probably related to vitamin D deficiency that she had never been pregnant. So I advised her to relax and get more sun. ”

Hu Yajun, director of the Reproductive Medicine Center of Wuhan First Hospital, said: "In our center, we mainly have infertility or recurrent miscarriage patients, and we usually do vitamin D testing, and it can be said that more than 90% of them are vitamin D deficiency. ”
Vitamin D is very important for the human body, but what does it have to do with sun exposure? According to doctors, vitamin D required by the human body is difficult to supplement through food, and is mainly synthesized by ultraviolet rays irradiating the skin. That's why she advised Ms. Hu to spend more time in the sun.
Hu Yajun, director of the Reproductive Medicine Center of Wuhan First Hospital: "Some women are particularly beautiful and wrap themselves tightly under the sun, which is actually very unfavorable to the synthesis of vitamin D, so the vast majority of people will have vitamin D deficiency. ”

For this reason, doctors recommend that the public choose to avoid exposure to the sun in the morning or at 5 or 6 o'clock in the afternoon in summer, and have proper exposure to the sun.
