The Situation
You can sometimes sense darkness - both physical and atmospheric - which results from dense foliage, overgrown hedges and close proximity to a woodland.

The Effects
This stifles Yang, which is represented by light and creates a stuffy and heavy atmosphere in the house.

The Solution
The foliage should be cut back to reduce the negative effects of Yin. Where possible, more windows should be added. If this is not possible, light curtains should be used and drawn beyond the edge of the window where they open.
