This is the UV ray that can cause sunburn, as it is the second most potent radiation. There are two processes to get a tan.
UVA radiation first creates oxidative stress, which leads to the darkening of the melanin. The second phase is where UVB radiation triggers our skin cells, which increases the production of melanin.
As a result, the skin forms a tan. You might think that staying under the shade can lessen the likelihood of you getting a tan. The reason for it is that the sun is reflecting off of the objects in your environment. So, even though you are not directly under the sun, you can still be exposed to its UV rays. The type of shade you have can protect you from the UV rays.
And, although they provide some protection, no shade is completely safe. Take note, too, that not all shades are equal. For example, thick shades from buildings can offer more shade than a beach umbrella. Hence, taking care of your skin when tanning is a must. Ninety percent of the UV rays can still pass through the fluffy clouds. People with less melanin have fairer skin which burns more easily and are more likely to burn — they also may struggle to tan at all but it will mean having to tan gradually in short bursts.

In fact, you can land up badly burned from tanning in overcast weather.
Windows provide around SPF30 protection, so it is still possible to get a tan through a window, you will just have to be sitting next to a window with strong sunlight to notice a difference. It is possible to tan through clothing. While different fabrics and materials offer different levels of protection, UV rays can pass through most ordinary clothing, and you can wind up getting a tan through your clothing.
Truthfully, the best way to avoid sunburn is to stay indoors in a dark room. UV rays can still reach your skin while you are indoors, whether it is through your window or reflecting off of the floors by the open door.
This is why it is so important to always have some sort of sun-protection on you, as you never really know when you are being burned. At the end of the day, any contact with UV rays is harmful. They only damage your skin and can even cause lasting damage, no matter how much you want that golden glow. It is much safe to opt for a self-tanning lotion or a spray tan at a salon. Not to promote any paranoia about the sun, but it is very possible to get a tan even when you think you are safe from the sun.
