What flowers are put in the bedroom for human health?

It is reported that plants such as Zi Yuan, Astragalus membranaceus, tobacco and Celosia cristata can attract a lot of radioactive elements such as uranium. Aloe, chlorophytum and Eupatorium adenophorum can remove formaldehyde; Ivy, rose, rose, aloe and evergreen can effectively remove trichloroethylene, sulfur specific hydrogen, benzene, phenol, hydrogen fluoride and ether indoors; Pigeonpea, Phyllostachys pubescens and Eupatorium adenophorum can absorb more than 80% of indoor harmful gases; Asparagus can remove heavy metal particles; Citrus, rosemary and chlorophytum can greatly reduce bacteria and microorganisms in indoor air.

In addition, chlorophytum can effectively absorb carbon dioxide; Some fleshy flowers of cactus rarely emit carbon dioxide at night; Wisteria has strong resistance to sulfur dioxide, chlorine and hydrogen fluoride, and also has certain resistance to chromium. Some leafy and water-loving plants, such as radish, can keep the indoor air humidity in an excellent state.

Although raising flowers at home has many advantages, we should pay attention to the arrangement of flowers in the bedroom, because flowers release oxygen and absorb carbon dioxide during photosynthesis during the day; But at night, flowers do not carry out photosynthesis, not only spit out carbon dioxide, but also absorb oxygen. Therefore, in the bedroom, it is best to put less or no flowers at night to avoid them competing for oxygen and affecting health.

Some flowers can freshen the air, but at the same time, they also have some negative effects on people, so it is best not to put them in the bedroom. For example, although Chinese rose can absorb a lot of harmful gases, its rich fragrance will make people feel depressed and uncomfortable, hold their breath and even have difficulty breathing; Rhododendron, tulip, lily, poinsettia, etc. can also absorb volatile chemicals, but Rhododendron flavum contains a toxin, which can lead to poisoning and shock in severe cases (not for sale in the market), but most Rhododendron contains some volatile oil and azaleas, which have certain curative effects on tracheitis and asthma. On the other hand, tulip flowers contain a toxic alkali, which is reported to accelerate hair loss when exposed for too long; The fragrance of lily, if smelled for a long time, will make people's center excessively excited and cause insomnia.
