Does the house shade for too long have an effect on health?

Yes, it does affect people's health, and it is really bad in Feng Shui. Because everything depends on sunshine. If plants can't see sunlight, they won't do photosynthesis, and they will stop growing or die gradually. If animals and humans don't get sunlight, they will lack nutrition, such as vitamin D, which will breed bacteria and viruses, and people will get sick and affect human health. The house has not been in the sun for a long time, and it has been dark for a long time. If coupled with unfavorable factors such as humidity and lack of ventilation, if people live in this environment for a long time, it will inevitably affect people's thoughts and emotions, bring certain psychological pressure to people, and thus make people suffer from different degrees of mental illness. At the same time, because the house breeds bacteria and viruses, it seriously affects people's health and produces diseases. Geomantic speaking, the so-called auspicious house must be a room with sufficient sunshine, good ventilation, clean and bright. This is why when people buy a house and choose a house now, they all like to buy a house with the sun shining in the east room facing south or west, instead of choosing a house facing south or west where the sun can't shine. Therefore, sunshine is very important, which not only affects people's health, but also affects the quality of house feng shui.
