You Jie, an associate professor in the Department of Agronomy of China Agricultural University, believes that this statement has some truth. If you must put flowers and plants indoors, it is recommended to put some plants that are small in size and can release oxygen at night, such as cactus, Phalaenopsis, Sedum, Chlorophytum, Aloe, Huwei Lan, keel and so on. These plants are not afraid of drying, they can release a proper amount of oxygen at night (due to their small size, the amount of oxygen released is just suitable for people to breathe), and at the same time, they can humidify the air. However, Professor You also pointed out that even these plants, if placed in the bedroom, should not be too much, just choose one or two pots. In addition, you should always spray water on plant leaves.
Wang Youjiang, Secretary-General of China Vanilla Industry Alliance, reminded that some plants with strong smell should not be placed indoors, otherwise it will easily stimulate nerves and affect sleep. Such as rose, rose, jasmine, Milan, tulip, lily, cordate telosma, clove, lavender, mimosa and so on. , smell sensitive, especially not suitable for people with hypertension and heart disease or pregnant women.
In addition, it is best not to put fresh cut flowers in the vase in the bedroom. Because fresh cut flowers are soaked in water in vases for a long time, the roots of flower branches will be soaked and rotted, moldy, and will breed mold or bacteria. They not only do not produce oxygen, but also release carbon dioxide, which affects health.
Don't put too fragrant potted plants in the bedroom.
Since ancient times, planting flowers and grass has been the cultivation of literati. In modern society, decorating rooms with plants and flowers can not only beautify the environment, but also add a little interest to life. However, the selection, placement and even collocation of containers in the living room are all learned. To this end, experts put forward some suggestions, let's create an elegant living environment together. Jasmine smells fragrant after flowering, and many people like to put it in the bedroom and sleep with the fragrance. However, this may be detrimental to the health of some people.
The fragrance of flowers such as jasmine is actually some volatile chemicals with complex components. Different people have different reactions to the same smell, which is related to the floral composition, concentration, environmental temperature, air velocity, people's physical condition and individual feelings of the plant itself. If the environmental space is large and the number of plants is small, it may not be a big problem. But for a long time in a rich floral environment, it is easy to cause adverse reactions such as poor breathing, dizziness, nausea and chest tightness.
In addition to jasmine, it is best not to put other fragrant flowers in the bedroom, such as lily, cordate telosma and epiphyllum.
Lily flower fragrance contains a special stimulant, which will stimulate people's central nervous system, make people excited and even cause insomnia; Cordate telosma will release a lot of waste gas, which will raise people's blood pressure. Patients with heart disease and hypertension will feel chest tightness and shortness of breath after smelling it, and long-term contact is easy to cause harm to health.
Epiphyllum will release a strong aroma when it blooms, and it will easily cause dizziness, nausea and other adverse reactions when the concentration is too high.
Milan, rose, Daphne and other flowers should not be placed in the bedroom.
In addition, a large number of plants should not be placed in the bedroom, because most plants breathe at night and release carbon dioxide, which affects air quality; Plant transpiration can also make the air humidity too high, which makes people feel uncomfortable.
If you like fragrant flowers, you can put them in the living room and other environments with large space and good air circulation.
If you need to put it in the bedroom, you can choose 12 pots of suitable flowers according to the size of the bedroom, and odorless green foliage plants are more suitable.
