Can I sunbathe through the glass?
Before answering the question, whether it is possible to tan through glass, it is necessary to understand what factors cause sunburn.
The human skin contains melanocyte cells,and they darken under the influence of sunlight, providing a beautiful tan. However, melanocytes become active not from heat rays, but from ultraviolet.
There are three types of ultraviolet rays: A, B and C.
- The rays of C reach the ground in such small quantities that they practically can not be taken into account, considering such a phenomenon as sunburn.
- The greatest activity is caused by rays B, it is under their influence that the greatest activity of melanocytes occurs and the strongest and most intense sunburn turns out.
- The rays of type A are more sparing. But under their influence, you can also tan. However, the process will take much longer than tanning under type B rays.
Now back to the window pane. It perfectly passes heat rays, does not pass ultraviolet rays of type B, and rays A passes in a diffused form. And if a very long time to sit under the glass, then, in the end, you can slightly tan. But this process will take a week.
