Do you have to have a window in a bedroom?
Yes,it's very important to have a window in a room because fresh
air will circulate in the room when we open the window, you need
ventilation in a room, otherwise it will be very stuffy and it
won't be good to stay very long period in an unventilated room.
Furthermore, light will shine into a room with window...you will be
disoriented and get sick easily in a room without window. The other
plus point is you will be able to see the scenery outside your
room...that is nice..isn't it?
this is also a emergeny exit incase the other exit is
blocked
