What flowers can make people sleep peacefully in the room?

Because not all plants are suitable for indoor display, it is necessary to distinguish indoor plants and invite only those that are healthy. And all this, we must fully understand the relationship between indoor plants and human health in advance.

Aloe, chlorophytum, Eupatorium odoratum, Eupatorium odoratum and Dendrocalamus giganteum are natural scavengers. The research shows that aloe vera, Eupatorium odoratum and chlorophyllin have strong absorption ability to indoor harmful gas formaldehyde.

Cycas evergreen, chrysanthemum, kumquat, pomegranate, mirabilis jalapa, Scutellaria barbata, rose, camellia, Milan, daisy, wintersweet and marigold can absorb harmful gases emitted by household appliances and plastic products.

The volatile oils of rose, osmanthus fragrans, violet, jasmine, lemon, rose, carnation, lily of the valley and Lagerstroemia indica have obvious bactericidal effect. Crape myrtle, jasmine, lemon and other plants can kill protobacteria, such as diphtheria and dysentery bacteria, within 5 minutes. The fragrance of jasmine, rose, carnation, lily of the valley, violet, rose, osmanthus and other plants has obvious inhibitory effect on the growth and reproduction of mycobacterium tuberculosis, pneumococcus and staphylococcus.

Hupilan, Huweilan, tequila, palm, dwarf kale, striped kale, Sedum, and cultivated pineapple can purify the air at night. If you put two pots of this plant, such as pineapple, in a room of 10 square meter, you can absorb all the carbon dioxide discharged by a person at night.

Cactus, lotus, fairy finger, ruler and epiphyllum can increase negative ions. Turn on the TV or computer indoors, and the negative oxygen ions will decrease rapidly. The stomata on the fleshy stems of these plants are closed during the day and opened at night, which absorbs carbon dioxide and releases oxygen at the same time, increasing the concentration of negative ions in indoor air.

Orchids, osmanthus fragrans, wintersweet, cauliflower taro and osmanthus fragrans can absorb suspended particles and smoke in the air. Lilac, jasmine, rose, violet, chrysanthemum, mint, these plants can relax people and help them sleep.

In addition, plants that are too bright and harsh, have peculiar smell or are too fragrant should not be placed indoors. Such as: oleander, oleander and Datura flower. These flowers and plants are poisonous and harmful to human health. The fragrance of cordate telosma has a strong stimulating effect on people's sense of smell, and it will also discharge a lot of waste gas at night, which is not good for people. Evergreen stems and leaves contain dumb enzymes and calcium oxalate, which will cause strange itching when touching the skin, and poisoning when eaten by mistake. Other plants, such as tulips, contain poisonous alkali; Mimosa, frequent contact will cause hair loss; Narcissus, contact with leaves and flower juice, can cause skin redness and swelling.

And:

Recently, NASA scientists found that many evergreen foliage plants and green flowering plants have the function of eliminating toxic chemicals in buildings. The study also found that plants not only rely on leaves to absorb substances, but also the roots of plants and bacteria in the soil contribute to the removal of harmful substances. Zhou, an engineer at the Indoor Environmental Monitoring Center of China Decoration Association, believes that the following two types of plants are most suitable for indoor use.

Plants that can absorb toxic chemicals.

Aloe, chlorophytum, Eupatorium odoratum, Eupatorium odoratum and Dendrocalamus giganteum are natural scavengers, which can remove harmful substances in the air. Studies show that Eupatorium adenophorum and Eupatorium adenophorum can absorb more than 80% of indoor harmful gases, and their ability to absorb formaldehyde is super strong. Aloe vera is also a good hand at absorbing formaldehyde, which can absorb 90% formaldehyde contained in 1 m3 air.

Ivy, cycad, chrysanthemum, kumquat, pomegranate, Scutellaria barbata, rose, camellia, pomegranate, Milan, daisy, Chimonanthus praecox, marigold, etc. can effectively remove harmful substances such as sulfur dioxide, chlorine, ether, ethylene, carbon monoxide and nitrogen peroxide.

Orchids, osmanthus fragrans, wintersweet, cauliflower taro and osmanthus fragrans are natural dust collectors, and their cilia can intercept and absorb suspended particles and smoke in the air.

Plants that can kill bacteria

Volatile oil produced by fragrant flowers such as rose, osmanthus fragrans, violet, jasmine, lemon, rose, carnation, lily of the valley and crape myrtle. Has obvious sterilization effect.

Crape myrtle, jasmine, lemon and other plants can kill diphtheria, dysentery bacteria and other protobacteria within 5 minutes. The scents of roses, carnations, lilies of the valley, violets, roses, osmanthus flowers and other plants have obvious inhibitory effects on the growth and reproduction of mycobacterium tuberculosis, pneumococcus and staphylococcus.

Cactus and other succulents native to tropical arid areas, the stomata on their succulent stems are closed during the day and opened at night, which absorbs carbon dioxide and produces oxygen at the same time, increasing the concentration of negative ions in indoor air.

Plants such as Hupilan, Huweilan, Tequila, Palm, Kale, Sedum, Rooting and Pineapple can also purify the night air.

Climbing plants such as Parthenocissus tricuspidata, grape, morning glory, wisteria, rose, etc. Planting around the house can make it climb along the wall or along the shelf to form a green arbor, which can effectively reduce sunlight radiation and greatly reduce the indoor temperature.

Lilac, jasmine, rose, violet, mint and other plants can make people relax, feel happy, help sleep and improve work efficiency.
