It's not good from the perspective of Feng Shui or science. On the mysterious terms in Feng Shui. From a scientific point of view, poor light will make the room dark and humid, and it is easy to breed bacteria. There are also bad effects on people's minds.
Scientifically speaking, insufficient light will make the bedroom too dark and humid. Too dark and damp bedroom is not only harmful to health, but also may affect the mood of the residents in the long run, leading to a new loneliness of the residents and reluctance to contact with people too much. At present, most of the urban housing patterns have such problems, but these defects can be basically solved by placing feng shui items and conditioning.
But a dark and damp house is no matter how cheap it is. It's best not to choose either, because the house with insufficient lighting and heavy internal humidity is especially unsuitable for people to live for a long time. Such a house is a damp place.
People live in a house with excessive yin for a long time, so that their own yang magnetic field is slowly consumed, which will not only affect the health of residents, but also have a negative impact on their luck and mood.
Dark and damp houses are even more unsuitable for single women, especially single women with poor physical fitness should avoid living in such houses. Because women themselves belong to yin, when they live in a dark and humid room, yin and yang are even more unbalanced. Residents not only have physical and emotional problems, but also have nightmares and paranormal phenomena when they are in poor health. Women had better stay away from such a house.
If a woman already lives in such a house, of course, she may simply say to change the house, but if possible, open more windows or vents to let the air circulate, let the outside light in, and increase the yang in the house. If you don't open the window, you can only choose a palliative.
