How to create a healthy living environment
Comfortable and elegant rooms have a good influence on people's physiology and psychology. If you want to design a reasonable room, you should design it according to the nature of use, lighting, space size, furniture and personal interests. Want to make the room comfortable, elegant environment, generally from the following aspects:
1. Color should be good for health. Generally speaking, the living room and dining room are decorated with light yellow, which can add a happy and soft atmosphere; Decorating the study with light green will make people feel quiet; Decorating the bedroom with light pink can make people sleep peacefully in a warm and comfortable atmosphere; You can use gray in the kitchen and bathroom, because gray gives people a relaxed feeling. If the room is well lit and the furniture is light, you can paint the wall with neutral and cold colors such as lake blue or light blue. If the room is dark and the furniture is dark, the walls should be warm colors such as beige and milk yellow. If you are a middle-aged or elderly person with weak constitution or bradycardia or hypotension, you should decorate the room with warm colors, which will help enhance the function of the circulatory system and promote metabolism; If you are a patient with hypertension or coronary heart disease, or have no patience, you should decorate your room with cool colors to create a quiet atmosphere for the patients.
2. The light should be soft and bright. Dim indoor light will make people feel depressed, lonely and depressed; On the contrary, too strong indoor light will make the cerebral cortex highly excited, and the heartbeat will accelerate, which will make people easily tired. Soft and bright light will make people feel comfortable and refreshing. Generally, a 40-watt fluorescent lamp or energy-saving lamp and a 25-watt incandescent lamp should be installed in a room with an area of 10 square meter or more, so that the indoor light at night will be close to the brightness during the day. When installing chandeliers, ceiling lamps or other lanterns, the brightness should also be based on the above principles. When writing at night, you can put a 25-watt light green lampshade desk lamp, which is good for protecting your eyes. A light blue wall lamp should be installed above the bedside of the elderly.
There should be a suitable indoor climate. A room with a good environment has plenty of sunshine, fresh air, quiet and tidy, and sufficient light. Indoor humidity, temperature, airflow, radiation, dust concentration, etc. , must meet the standards. The standard temperature is about 22 ~ 32 in summer and 14 ~ 20 in winter. The temperature difference between day and night should not exceed 4 ~ 6. The cooling time of air conditioner should not be too long and the humidity should not be too high, otherwise it will be cold in winter and not conducive to the evaporation and heat dissipation of human sweat in summer; Too low humidity is also bad, because it will dry the mucosa of population, nose, trachea and pharynx, make the capillaries fragile and easy to rupture, and also infect the upper respiratory tract.
4. Decoration and layout should be pleasing to the eye. According to personal hobbies, put some potted flowers indoors, hang some celebrity calligraphy and painting or raise some tropical ornamental fish to decorate the room elegantly, exquisitely and generously. It also has the function of nourishing emotions and making people enjoy it. You can also put some Tang tri-colors, small animal toys, plaster statues, wood carvings and other handicrafts in low cabinets or high and low cabinets, antique shelves and so on, giving people beautiful enjoyment.
What are the disadvantages in the room?
What are the disadvantages in the room?
Healthy people spend more than two-thirds of their lives indoors. Indoor microenvironment refers to classrooms, bedrooms, workshops, workshops, etc. Compared with other pollution, indoor environmental pollution is more rapid and direct to human health. It is harmful to human health in the following aspects:
1. Pollution of some commodities. With the improvement of people's living standards and the pursuit of a new life, detergents, cosmetics, pesticides, deodorants, adhesives, polishing agents for furniture and leather, and artificial mothballs in wardrobes are bought back by people because of their different functions, but these things are all toxic. Because they will seriously pollute the indoor environment, if you don't pay attention to indoor ventilation, you will be poisoned.
2. Human excrement pollution. Scientists' research shows that people who stay indoors for a long time will gradually increase the concentration of various chemicals discharged by themselves. Especially when there are too many people living indoors, due to the small room area, plus people's sweating, breathing and heat dissipation, these are easy to pollute the indoor air, which will easily lead to a significant increase in temperature and humidity, an increase in carbon dioxide content and a bad smell. It was found that 1 1 common poisons in indoor air were higher than those in outdoor air. When the indoor air condition worsens, it will make people dizzy, tired and memory decline, and at the same time, this environment is also easy to spread respiratory diseases.
3. Pollution of building materials and decorative materials. Modern home decoration uses marble, granite, wood floor, carpet, wallpaper, artificial fiberboard, paint adhesive and other materials. These materials are harmful to human body, because they will continuously release a variety of toxic chemicals into the room, among which radon and formaldehyde pollution are the most harmful. Fresh aerated concrete will release radon, and unqualified granite and marble will also release radon; Formaldehyde will be released from synthetic wood floors, man-made fiberboards, furniture and paints. Living in such an indoor environment will lead to a series of symptoms such as dizziness, headache, inflammation of eyes and eye mucosa, dry skin and inflammation of nasal mucosa.
4. Volatile organic compounds pollution. Up to now, 307 kinds of volatile organic compounds can be detected in indoor air. Some of these organic substances come indirectly from the outdoors, such as schools, houses or workshops located in chemical plants, smelters, cement plants, paint factories and traffic trunk lines, and there will be many kinds of organic substances indoors. In addition, organic substances that pollute the indoor environment will also be discharged from the gas stoves and stoves in the family kitchen. These organic compounds mainly include benzene, toluene, formaldehyde and so on. If the concentration exceeds a certain level, these organic substances are harmful to the pharynx, eyes, nasal mucosa and exposed skin, causing headaches and autonomic nervous disorders. Studies have confirmed that formaldehyde and benzene can cause cancer. Therefore, we should do more outdoor activities and be ventilated indoors. The number of natural ventilation in the living room generally requires 2 ~ 3 times a day, 2 times in the bathroom and 3 times in the kitchen.
A seemingly tidy room can also make people feel uncomfortable, because some building and decoration materials contain many toxic chemicals, which are harmful to human health.
A beautiful environment starts with you and me.
