Detailed answer

You can get sunburned through a window, especially if the window does not have any protective coatings. While glass can block some UVB rays, it does not provide sufficient protection against UVA rays which can still penetrate through and cause sun damage. Additionally, if you are sitting close to the window, the intensity of the sun's rays can be magnified, increasing the risk of sunburn. It is important to always apply sunscreen, even when indoors near a window, to protect your skin from harmful UV radiation.
