Take it easy when the flowers and trees enter the house.

People who cherish flowers can't see their beloved flowers and trees buried by frost and snow. If the weather is a little cold, they will move indoors, thinking that they can not only maintain the evergreen scene of flowers and trees, but also purify the indoor air. I don't know. It's likely to backfire.

We know that green plants can carry out photosynthesis only when there is enough light during the day, inhaling carbon dioxide and releasing oxygen, which makes people feel fresh and pleasant. But when the flowers placed indoors do not have enough light or turn off the lights at night, the flowers enter the breathing stage, absorbing oxygen and releasing carbon dioxide.

According to the experimental determination, only when the 100-watt light bulb is placed at a height of 1 meter at night can the flowers carry out photosynthesis. There are no such conditions in the family. In this way, the more green flowers you put indoors, especially in the bedroom, the more carbon dioxide you exhale. Carbon dioxide is not easy to flow, but also heavier than the air, and doors and windows are closed in winter nights, limiting air circulation, carbon dioxide will accumulate more and more at the bottom. Especially in the latter part of the night, the indoor carbon dioxide concentration will be higher and the oxygen concentration will be less and less. Sleep in the state of hypoxia for a long time, it is easy to cause persistent fatigue, people will feel stuffy, sleep quality decline. In addition, the following flowers are particularly harmful and should be paid special attention to.

Mimosa and tulip plants contain a harmful alkali ingredient. Excessive contact with people will cause sparse eyebrows, yellowing hair and, in severe cases, hair loss and dizziness.

Poinsettia and Yu Meiren are poisonous and highly toxic. Eating Yumei by mistake can cause disorders of the central nervous system and, in serious cases, can be life-threatening. The white milk in the stems and leaves of poinsettia can cause redness and swelling of human skin, such as eating stems and leaves by mistake, there is a risk of poisoning and even death.

The bulbs of daffodils and southern bamboo daffodils contain biotoxins, which can cause enteritis and other diseases after eating by mistake, and their leaves and flowers will make the skin red and swollen. The whole plant of Phyllostachys pubescens is poisonous and contains poisonous ingredients such as Phyllostachys pubescens and Phyllostachys angustifolia glycosides. Accidental eating can cause systemic convulsions, convulsions and coma.

The fragrance of rose, orchid and lily is so strong that some people often feel chest tightness and discomfort, hold their breath and have difficulty breathing, while others will lose sleep because of excessive excitement.

When nocturnal incense stops photosynthesis and enters the respiratory stage at night, it can emit a large number of particles with strong irritating odor. Patients with high blood pressure and heart disease are easy to feel dizzy, depressed and uncomfortable, and may even aggravate the condition.
