If white spots can't be exposed to the sun, is it better to work at night?

There is a big misunderstanding about whether patients with leukoplakia can bask in the sun. Some patients mistakenly believe that more sun exposure can increase melanin, so exposure leads to aggravation of the disease. In addition, some patients do not see the sun all day and hide at home, which is not conducive to the treatment of leukoplakia. Leukoplakia can occur in spring, summer, autumn and winter, but it is more common in late spring to summer, and most of them have a history of sun exposure before the onset.

This is because the sun shines directly on the ground in summer, and the irradiation intensity is large. After exposure, it is easy to cause skin inflammation, leading to the damage of melanocytes and the loss of the ability to produce melanin, so there are depigmentation, erythema, even blisters, and burning sensation. The white point is larger than the main range. In daily life, the color of human skin is constantly influenced by the external environment and seasonal changes, and the most important factor is sunlight.

People's skin color will gradually deepen in summer and become lighter in winter. The skin color of outdoor workers is much darker than that of indoor workers, and it is also because they have more opportunities to contact the sun and often contact the ultraviolet rays under the sun.

Hua Hai said that moderate sun exposure can promote the production of melanin, accelerate the transfer of melanin from melanocytes to all layers of epidermis, deepen skin color, and be beneficial to the treatment of leukoplakia. We can't generally say that sunbathing for patients with leukoplakia is not good, and of course we can't say that sunbathing for patients with leukoplakia must be very good. The key is to grasp the timing and degree when sunbathing.
