Flowers are a symbol of beauty and a sign of health and progress. There are many flowers in life, which not only have ornamental value, but also have the effects of beauty beauty, nourishing and prolonging life, treating diseases and strengthening the body. Flowers and people's lives are inextricably linked directly and indirectly.
First, beautify the environment.
Choose all kinds of flowers with certain ornamental value indoors and outdoors, plant and place them according to certain aesthetic principles, so that people can live, live and study in a beautiful and comfortable environment and bring people a happy mood.
Second, adjust the climate.
Flowers and trees can adjust the temperature and humidity of the air. Where there are flowers, you can form a small environment that is warm in winter and cool in summer. According to the measurement, the temperature can be reduced by 3 ~ 5℃ and the humidity can be increased by 10% ~ 20% in places with trees in summer.
Third, purify the air.
Many flowers have the function of adsorbing and filtering all kinds of dust in the air. According to the measurement, the dust in the place where there are trees and flowers is 56.7% less than that in the open space, which is also 1.5 meters from the ground. Flowers can also provide a lot of oxygen. According to the measurement, it can absorb carbon dioxide 1.5g per square meter of leaf area per hour (equivalent to 3 times of carbon dioxide exhaled by an adult every day) and release 3.8g of oxygen. The huge leaf area can continuously provide oxygen and fresh air through continuous photosynthesis. Indoor, the room with flowers contains 50% less mold and bacteria than the room without flowers. Flowers can absorb toxic gases harmful to human health, such as sulfur dioxide and hydrogen fluoride, but the flowers themselves are not harmed. Flowers and trees transmit the absorbed harmful gases to the roots, and microorganisms parasitic on the roots will decompose them. It has also been found that there are some succulents similar to cactus that grow in tropical arid areas, and their photosynthesis mode is completely different from that of ordinary plants. They only open their stomata at night to absorb carbon dioxide, and completely close their stomata during the day, so that the carbon dioxide produced in the process of breathing at night can be absorbed and digested by themselves, and will not be excreted, thus making the air fresh. According to the measurement, a pot of pineapple can absorb more than100g of carbon dioxide every night. A person emits about 300 grams of carbon dioxide in 8 hours at night. In this way, as long as you put two pots of pineapple in the room of 10 square meter, the indoor air can be completely fresh.
Fourth, medical care.
According to statistics, there are hundreds of kinds of flowers that can emit different scents. The fragrance of flowers can make people feel comfortable, eliminate fatigue and treat diseases at the same time. For example, cloves can relieve pain; Pine and cypress can secrete some fungicides.

These vitamins can reduce the wrinkles of human skin, increase the elasticity of skin, and have a strange effect.
The monitoring role of intransitive verbs
Some flowers will react quickly when they encounter some toxic substances, thus playing a role in forecasting. They can be called guardians of the environment. If pine and fir trees encounter sulfur dioxide, the needles will turn yellow and dry. Dingshan, apricot and walnut are sensitive to automobile exhaust. Rhododendron, peony, tulip, cherry blossom, evergreen, gladiolus, etc. Sensitive to hydrogen nitride, when exposed to toxic gases, purple or dark brown spots will appear on the tips or edges of leaves. This flower is very sensitive to ozone. The universe is sensitive to chlorine. They become alarms about the presence and concentration of toxic gases.
Seven. Predict special disasters
Some flowers and trees changed abnormally before the earthquake. For example, before the 1976 Tangshan earthquake, some willow branches in Tianjin died, bamboo blossomed, and fruit trees blossomed again after bearing fruit. Many apricot trees bloomed for the second time before the February earthquake in Liaoning sea area, 1976. These phenomena can be used as a reference for earthquake prediction.

Bloom is warm in spring. Flowers are not only a symbol of beauty, but also a natural "health care doctor" for human beings.
In this spring when birds are singing and flowers are fragrant, let's go out of the room and enjoy the beautiful scenery of nature's red flowers and green grass, which is equivalent to taking part in the best health-keeping exercise. "Flower viewing is an elegant thing, which makes people feel happy and prolongs life." Indeed, flower viewing is an activity that is beneficial to your physical and mental health.

Why does aroma have such obvious and magical effect and influence on people's emotions? Experts in the scientific field believe that after being absorbed by human respiratory mucosa, fragrance molecules stimulate human olfactory cells, thus affecting the excitement or inhibition of cerebral cortex, regulating systemic metabolism and balancing neurological function. After contacting with olfactory cells in nasal cavity, the smell of aromatic oil will be transmitted to cerebral cortex through olfactory nerve, which will make people feel "refreshed" and make blood vessels harmonious and unobstructed, thus naturally regulating various physiological functions of people.
"If you often walk among flowers, you can live to be 99 years old." When people are full of sadness and step into the world of flowers, the fragrance of flowers is refreshing and the sadness naturally disappears; When people are burning in anger, when they come to the flowers, the aroma will attack people, and it will also make you calm down and have the feeling of "looking at flowers and nourishing your heart". "The disease of seven emotions is also fragrant." Flowers can explain words. The fragrance of flowers is rich, and the flowers are like people. Seeing and smelling them seems to solve people's suffering and happiness. The faint fragrance seems to be telling softly, the strong fragrance seems to be singing happily, the faint fragrance seems to evoke good memories, and the faint fragrance seems to appease the troubled thoughts. The ancients said, "The pen doesn't look good at Yan dance, and the text is irrelevant to enjoy flowers." Yuan Mei, a famous litterateur in Qing Dynasty, also wrote a poem: "After three days of blue smoke, I only feel light and want to get up." These poems all illustrate the close relationship between flower appreciation and health preservation.
It is better to take medicine than to see flowers in spring. The famous writer Lao She wrote in his essay "Raising Flowers": "I always write dozens of words, so I went to the yard to have a look, watered the tree, moved the pot, then went back to the house to write more, then went out, and so on! The combination of mental labor and manual labor is beneficial to the body and mind and is better than taking medicine. " Mr. Lao She's experience in flower cultivation and appreciation is a good inspiration for our work and leisure. Zhang Henshui, a famous modern writer, loves to grow flowers all his life. Besides Four Treasures of the Study, his bookcase is full of flower arrangements. He once wrote: "Wild flowers collected in the countryside are often packed in water bottles for pens and inkstones. If you smile in the green leaves, flowers are sometimes charming. I throw a pen to get a small interest, and I feel embarrassed every time ... This is the most affectionate person in the case. " Caring for red flowers and green leaves will add endless fun to your life.
Going to the suburbs to enjoy flowers in spring can not only appreciate the beauty of nature, but also cure diseases. Isn't this a pleasure?
