Does the air freshener in the bedroom affect sleep?
The shadow doesn't affect sleep, I don't know, but it's not as good as a green plant.
No, as long as you get used to the taste, it's very slight to the human body
You'd better not. Use a humidifier
If it weren't particularly sensitive to odors, wouldn't the air freshener have reported bad health early in the year? Suggest putting some plants in the bedroom and the like
