Why does Feng Shui say that the head of the bed should not face the west?

The reason why "the head of the bed faces west" is considered unlucky by most people can be summarized as follows:

First, it is said that the Paradise of Paradise is in the West, so there are often " "Gui Xi" is used to describe a person's death; because of this, the world believes that sleeping with the head to the west is unlucky and even means illness and death.

Second, the sun rises in the east and sets in the west, and the west is where the sun sets. Therefore, it is not suitable to sleep in this gloomy direction, otherwise it will be harmful to the body and career, and will go downhill.

Third, the west-facing sunlight in summer is the strongest, so bedrooms and beds facing the west are particularly hot, and people in them are susceptible to the heat and fall ill, so the head of the bed facing the west is the best choice. Not very appropriate.

However, from a modern scientific point of view, the earth rotates from east to west. If you sleep with your head facing the west for a long time, it will cause blood to rush to the head, resulting in poor health.
