"Oranges have a fragrant aroma that can, to some extent, refresh the mind and purify the air." Professor Zhangfu Chang of Beijing University of Chinese Medicine suggests that placing an orange in the bedroom can provide a fresh scent that stimulates the nervous system, refreshing the mind, clearing the air, and beautifying the indoor environment.
Professor Zhangfu Chang points out that from the perspective of Traditional Chinese Medicine, the fragrant aroma of oranges can transform dampness, awaken the spleen, repel foul odors, and open the senses. In addition to refreshing the mind, when one feels fatigued, has a bloated stomach, and has no appetite, appropriately smelling the fresh scent of oranges can alleviate these discomforts. The aromatic fragrance can also calm the nerves and soothe the mind; placing an orange by the bedside is also beneficial for sleep. Furthermore, the soft color of the orange gives people a warm feeling, making it a clever decorative item for the indoors.
In addition to oranges, there are many other fragrant fruits, such as apples and bananas, which also have a certain impact on purifying the indoor environment. However, these scents can only serve as a supplementary means for maintaining health and need to reach a certain concentration to be effective.
