Because a person is at home, after all, he is not always sleeping, nor is he always lying on the sofa doing things, but he still needs to move around frequently and do something related to life or work. And at home, after all, we don't close all the curtains and all the windows, so once exposed, it will also have a bad influence on ourselves. So as long as you are not sleeping or working, it is recommended to wear clothes at home when you are not working.
