Should I apply sunscreen at home?
The short answer is yes. You should apply sunscreen even when you are indoors. But there is no actual black and white answer to this. It depends.
What are the benefits of using sunscreen indoors?
We couldn't stress enough that sunscreen is important not only if you are stirring for good skin but more importantly to protect it from harmful UV rays that pose threats such as skin cancer and other skin related diseases. The SPF rating on the sunscreens represents the level of protection you'll get from UVB rays. UVB is shorter wavelength sun rays that make your skin age faster and cause skin burns. While the effectiveness of a sunscreen against the longer wavelength sun rays, UVA can be measured with its PPD or PA or UVA Rating or sunscreen labelled as broad spectrum. Although UVA rays do burn the skin they may cause skin tanning, skin ageing and hyperpigmentation.

Factors to consider
Coming back to the main question ~ 'Should we apply sunscreen at home?' there are two factors that you must consider, let's dig deeper into it:
Level of Exposure
How sensitive your skin is to sun damage?
Questions to ask yourself!
It is quite obvious that you are more exposed to UV rays outside than indoors. However, even if you are inside the house, you must check whether you are exposed to the sun directly even indoors? May be sitting by the window or a glass door or anywhere where sunlight is hitting you directly. Or if you have sun exposure indoors diffused by the surrounding particles or the objects, for example, trees right outside your window where you are sitting or if you are a few meters away from the open exposure via doors or windows but even then with diffused exposure, the UV rays are reaching to you.
Usually, it is recommended to wear sunscreen if the UV index is 3 or more. The summers in India are hot as hell, and with the scorching sun over our heads, the UV levels average around 10-11 during the day (although it depends on the day and time of the year) across the country. Indian summer reaches its peak during May and June resulting in a higher UV index and thus, more exposure to UV rays.
Skin sensitivity to the sun
Coming to the second point in consideration is how susceptible your skin is to sun exposure. It depends on the condition of your skin and the products that you are using and thus, varies for each person. If you are using activities in your skincare routine such as AHA, Retinol, Vitamin C etc., it increases skin sensitivity and thus will lead to more UV damage if left unprotected. Or if you have a special skin condition that makes your skin more photosensitive (sensitive to sunlight or ultraviolet light and may burn easily), then you'll have to be more careful about sun care.
If you are reading this and want to develop a decent skincare routine, you are somewhat a skincare enthusiast even if it is at a subtle level. The benefits of wearing sunscreen outweigh the not using one by large. Direct sunlight even indoors is worth considering, as it can cause sun damage and therefore in such cases it is necessary to apply sunscreen at home. Having diffused exposure will cause less damage as compared to when you are outside or direct. In this case too, though we recommend you to apply for one as the sun rays are still reaching you.
But if you are in a well-secured room indoors with no such windows or doors where you are all secured from the outdoors, then you can skip sunscreen at home.
