Baobaojiu sleep in the light, but also affect the normal development of vision. We know that the benefits of light out sleep lie in the full rest of the eyes and ciliary muscles.
Hazards of light pollution - hazards of light pollution?
Light pollution
Now in the home decoration, people have taken indoor air quality as a top priority. However, another kind of pollution - light pollution is also quietly coming.
Human eyes can adapt to a certain range of light radiation due to pupil regulation, but when the light radiation increases to a certain amount, it will have adverse effects on the environment and human health, which is called light pollution.
Two thirds of people are in light pollution
According to a survey report in the United States, about two thirds of people in the world live in light pollution. Moreover, the pollution caused by man-made light is increasing year by year, with Germany increasing by 6%, Italy and Japan by 10% and 12% annually. One in 10 drivers around the world said that when driving in the hot sun, they would be suddenly attacked by the reflected light from the glass curtain wall, making them unable to see the direction for a moment. Dr. Russell Reiter, an endocrinologist at the center for Health Sciences at the University of Texas, even said that light is a drug. Abusing light is harmful to health.
Light is a drug
Whether it is incandescent lamp or colored light lamp, it has brought great aspects and interest to our life. But, you may not know, even Edison could not have predicted, that now the light will be criticized by experts as a drug. Sleeping at night is the inherent physiological rhythm of human beings, but in modern society, some of them are disturbed by the city lights. Light is an indispensable friend of human beings, but too strong, excessive and changeable light will cause interference and even great harm to human body, which many people have never thought of.
Harm of light pollution
When you are blinded by the light reflected from the glass curtain wall, you can instinctively raise your hand to cover your eyes or avoid the light. However, some light pollution and its harm may be unconscious. In recent years, the disputes caused by light pollution are increasing year by year, so we have to pay attention to its impact on health.
Damage to vision, leading to cataract
According to the investigation and research, the myopia rate of children who turn on the light to sleep at night before 2 years old is about 55%, while that of children who sleep with lights off is only about 10%. The bad visual environment caused by light pollution is considered to be an important factor in high incidence of myopia. More studies show that the incidence rate of cataract is 45% when working and living in white light pollution environment for a long time. Li Ying, chief ophthalmologist of Peking Union Medical College Hospital, told reporters that if the eye is exposed to strong light or color light for a long time, the function of eye lens will be affected, and cataract may be caused after injury. Therefore, when encountering strong light, we must avoid the naked eye.
Affect hormone secretion, even lead to precocious puberty in children
Dr Russell Reiter found that light on the retina at night reduces the production of melatonin, a hormone that regulates circadian rhythms. Light robs the night and disrupts the hormone secretion rhythm, which may lead to the imbalance of normal cycle. Wu Xueyan, Professor of endocrinology at Peking Union Medical College Hospital, said that if children are exposed to too much light, the secretion of melatonin will be reduced, leading to precocious puberty or genital overdevelopment. The secretion of other hormones also has a physiological rhythm. For example, the androgen reaches its peak at seven or eight o'clock in the morning, and the light will affect it. Light pollution will also affect people's mood, which will indirectly affect hormone secretion.
Upset, anxious, unable to sleep
Ms. Li, who lives on Nanjing West Road in the center of Shanghai, was disturbed by the neon lights of nearby high-rise buildings all night and had to seek a sleep expert. At first, I couldn't sleep, then I couldn't sleep. Then I was afraid, upset and anxious even at night. Shi Ming, a sleep expert and deputy director of the Shanghai insomnia Medical Cooperation Center, said that although people sleep with their eyes closed, light still passes through the eyelids, affecting sleep. According to his clinical statistics, about 5% - 6% of insomnia is caused by environmental factors such as noise and light, of which light accounts for about 10%. Once insomnia, the human body can not get enough rest, and will lead to deeper health problems.
It's depressing
Excessive exposure to light at night can lead to depression, Professor Randy Nelson of Ohio State University told the annual meeting of American neuroscience on January 21. Nie Jing also said that light pollution can lead to dizziness, upset, low mood, physical fatigue and other similar symptoms of neurasthenia.
For those who work at night or have a long-term night life, the damage caused by light pollution is greater. According to a study published in the Journal of the National Cancer Institute in 2001, the longer a woman works night shift, the higher the risk of breast cancer. Nie Jing also told reporters that long-term exposure to color light in dance halls can induce nosebleed, tooth loss, cataract, and even leukemia and other cancerous changes. Color light source is not only harmful to the eyes, but also interferes with the central nervous system of the brain, causing nausea, vomiting, insomnia, inattention, low libido and other symptoms.
What are the dangerous light sources
Hazard source: artificial day
Critical baby: Anzi 10 months old.
Anzi's home is in the bustling area of Beijing, surrounded by shopping malls and business districts. You can see tall buildings, neon lights, glass curtain walls, etc. Especially at night, under the illumination of various lights, advertising lights and neon lights around the house, it is as bright as in the daytime. Anzi is more and more fond of playing outdoors. Every day, she always lies on the balcony, grabs the fence and looks down.
Expert opinion: lighting will seriously disturb the human body's normal biological clock and seriously affect the baby's growth and development. At the same time, it will make people dizzy, upset, and even appear insomnia, loss of appetite, depression, physical fatigue and other similar symptoms of neurasthenia.
Coping strategies: after listening to the expert's explanation, mom and dad immediately moved their home to a quiet community. The greening was very good, with small bridges and flowing water, big trees and grass, and flowers all over the garden. Anzi could also play freely in this world! At the same time, in the window, desk, balcony, corner and other places decorated with some green plants or seasonal flowers, the fresh breath of nature into the room, improve and adjust the living environment.
Source of danger: white light
Dangerous baby: running for 4 months.
Benbenjia is a two bedroom house with polished marble floors. Because the house is not big, so the wall of the room connected to the balcony has been broken down and replaced with glass decoration, which not only enhances the light, but also makes the room visually larger because of the connectivity. In order to make the light of the old house better, the wall surface is easy to be cleaned, the paint chooses the high brightness washable material.
Expert opinion:
Generally, the light reflection coefficient of the white powder wall is 69% - 80%, while that of the mirror glass is 82% - 88%. If the decorative surface is too bright, the reflection coefficient will be as high as 90%, which is beyond the scope of human body, and the retina and iris will be damaged in different degrees. Exposure to bright light is very easy to affect the visual development of the baby.
Try not to use glass, polished marble, aluminum alloy and other materials for large-area decoration, and try to use less white and metallic tiles, glazed tiles and mosaic decoration with strong reflection. The floor should use the wood floor with smaller reflection coefficient as far as possible. At the same time, the paint on the wall should also choose the one with low light reflection coefficient, the color should not be too white, and the color should be soft.
Coping strategies: after listening to the expert's advice, my dad immediately adopted practical and effective improvement strategies. First of all, the marble floor was replaced by wooden floor, and the glass wall was hung with cloth curtain, especially when the sun was strong. The wall is repainted, this time chose the green that has protective effect to baby's eyesight.
Source of danger: colored light
Dangerous baby: Qiqi, 6 months old.
Qiqi's parents are fashionable parents. The decoration of the house is very fashionable. All kinds of luxurious lighting are installed. Especially in the evening, the lighting makes the house very beautiful. Qiqi is always staring at these various and colorful lights with her small eyes open. Her mother likes it when she looks at her baby and hears that color can stimulate the development of her baby's eyes. So she often turns on all the lights at home and lets her dance and chase the lights with her eyes.
Expert opinion: the color is disorderly, too dazzling light, to the baby is also a kind of light pollution. Dazzling lights not only harm visual function, but also interfere with brain function. The baby is particularly sensitive to light stimulation. When stimulated by light, the brain will produce a series of adverse reactions, which not only affect the development of vision, but also may cause dizziness, dizziness, insomnia and depression, and even cause palpitation and fever.
Coping strategies: indoor lighting should be simple, reasonable distribution of light sources, the direction and intensity of light irradiation should be appropriate, to avoid glare, usually only turn on soft light, at the same time avoid direct contact with the baby's eyes.
Dangerous source: Yuba strong light
Dangerous baby: Angel 13 months old.
The weather is getting colder. In angel, who lives in the south, he often catches a cold after taking a bath. In order not to let her get cold, her mother used the strategy of turning on all the lights of Yuba, thinking that the bag would not freeze.
Expert opinion: Although Yuba is easy to use, you should be careful of radiation if you use it for a long time. Yuba's temperature rises rapidly. Most of Yuba's four bulbs add up to about 1200 watts. Strong light is easy to cause light pollution, and strong light is easy to burn infants' eyes and skin. When taking a bath, the baby mostly uses the small hand to rub the eye movement. Don't think it is caused by the water, shower gel and shampoo into the baby's eyes. It may be caused by the light of Yuba.
Coping strategies: when using Yuba, do not let the strong light directly on the baby. If you feel uncomfortable, you should stop using it in time. It's better to use other heating methods (such as hot hair dryer) to make the bathroom warm, and then take a bath for the baby.
Source of danger: night light
Critical baby: Sichuan 5 months old.
Chuanchuan's parents are researchers and typical night owl parents. In order to facilitate the night care of the baby, but also worried about the baby's fear of the dark room, so in the bedroom equipped with a long light, so that Chuanchuan used to sleep under the light. In this way, mom and dad can safely read books to check information, the baby can also obediently sleep.
Expert opinion: scientists have found that any artificial light source will produce a subtle light pressure, which will make the baby appear restless and emotional, so that it is difficult to sleep. At the same time, let the baby sleep under the light for a long time, and then affect the reticular activation system, so that their sleep time is shortened, sleep depth becomes shallow and easy to wake up. In addition, the baby does not get enough rest, which will lead to deeper health problems. So let the baby sleep in a dark room is conducive to the development of vision and physical health.
Coping strategies: Mom and dad should turn off the light when the baby is asleep to avoid light sleep, so that the baby's eyes and ciliary muscles can get sufficient rest. Turn on the lights in the corridor outside the bedroom, or let the natural light outside adjust the brightness.
Source of danger: camera flash light
Baby in danger: Nannan, 3 months old.
The baby has just passed 100 days. In order to get the best shot and make a good memory, my father spent a lot of time around the baby. He changed his way to take pictures of the baby's various shapes, even at night. Look at the baby's lovely video record, it is really a very happy thing!
Expert opinion: from a medical point of view, the baby's visual nervous system is not fully developed after birth to the age of 3, and strong light will cause adverse effects on the development of ophthalmic system. In particular, the strong light of the electronic flash has a strong impact on the retina. If the distance is within 1 meter, the damage to the baby's eyeball will be greater.
Coping strategies: when taking photos for children under half a year old, the flash lamp should be used with caution or not, and natural light should be used as far as possible; if used, the illumination angle of the flash can be changed to shoot from the ceiling or side to the wall, or take pictures with slow shutter speed and wide aperture, so as to obtain ideal baby photos. There are some automatic cameras, when the light is not good, will automatically activate the flash, must pay attention.
Source of danger: TV flash light
Baby in danger: didi is 9 months old.
When didi was eight months old, she was very fond of watching TV. Mom and dad found that the baby watching TV become very focused and quiet, not to watch will cry. They think that some children's programs are not only helpful to the intelligence development and early education of the baby, but also can increase their knowledge and make up for the problem that they are busy with their work and have little time to accompany their babies. Therefore, they will not stop them forcefully.
Expert opinion: the image of TV is more fuzzy than the real object, and it often vibrates. When the baby is watching TV for a long time, his eyesight will be tired and his eyesight will be reduced. Sometimes in order to see more clearly, some babies will involuntarily appear crooked head posture, a long time, will lead to strabismus. Especially for children under 2 years old, their refractive, eye position and other regulatory systems have not yet developed well, so watching TV can easily lead to myopia.
Coping strategies: do not let the baby watch TV programs with flickering pictures and rapid changes for a long time. Children under 1 year old should not watch TV; 2-year-old children should rest for a period of time after watching TV for 20-30 minutes; 3-year-old children should not watch TV for more than an hour, and should go outside to play after watching a program.
How to avoid light pollution
In the family decoration, the lighting design should first consider the health, and then can consider the coordination and function. It is understood that unreasonable lighting tools and improper lighting methods will have a great impact on health: bright light can change the internal clock of the brain and control sleep; working under the light for too long will reduce the absorption of calcium by the human body. Therefore, when people decorate their new homes, they must pay attention to the problem of light health.
Light color should not exceed 3 kinds
The choice of light color should consider people's feeling in the room. Bedroom had better not use stimulating light color, and should avoid strong color contrast, avoid red and green collocation. And restaurants can choose yellow, orange lights, because these colors can stimulate appetite.
In addition, red light looks festive, but it is easy to make people's blood pressure rise, breathing faster; and white light can make hypertension patients blood pressure lower, calm.
The most important thing is that the use of light color can not go extreme, do not design the light into colorful, in order to avoid harm to human health. If the color contrast of light is too large, it can make people dazzled, damage eyesight, and interfere with the function of brain central advanced nerve. If the color is too much, it is easy to produce light pollution. If the color light pollution is suffered for a long time, it will induce nosebleed, tooth drop, blood pressure rise, cataract, and even lead to leukemia and other cancer. In addition, unreasonable light color will affect the development of children's vision.
It is better not to have more than three kinds of light colors in a room, and all kinds of colors should be coordinated and unified.
There should be at least two hours of sunshine every day
From the point of view of harmonious human settlement, the ideal home light environment is the organic combination of natural light and artificial light. As we all know, sunlight can kill harmful microorganisms in indoor air; human skin can produce vitamin D after receiving ultraviolet radiation in sunlight; sunlight irradiation can also prevent the occurrence of rickets in children; it can improve the immune capacity of human body. Experts believe that indoor sunshine for two hours a day is the minimum requirement for human health and development. In ancient times, people called the houses with abundant sunshine as Xiangyang mansion, and the houses with insufficient sunshine as shady houses, and considered the former livable and the latter not livable. At the same time, people also linked whether the house was sunny or not with the life span of the residents. The geomantic book said: how can people live a long life and welcome the sun without worry. Visible in the housing must have natural light, ancient and modern views are consistent.
In the stage of choosing residence, we should carefully investigate the lighting conditions of each space in the room, and it is appropriate to have a good vision without turning on the lights in the daytime. It is necessary to avoid direct sunlight and pay attention to the uniformity of illumination. Indoor half light and half dark is the performance of imbalance between yin and Yang. Some indoor spaces such as toilets and kitchens become black toilets and kitchens due to lack of sunshine, which is also harmful to the health of residents.
In the decoration stage, many people don't pay enough attention to the design of artificial light environment, and the installation of lamps and lanterns is not considered properly. As a result, the indoor lighting can not match the daily activities of the residents in the room, which makes the residents' eyes tired, eyesight reduced, and even headache, body fatigue, and mental fatigue. The survey shows that 70% of consumers don't know that improper lighting decoration will have a negative impact on Residents' health.
Indoor lighting should be soft, not too bright or too dark
Light and gas are two main factors to judge whether a house is livable. In ancient times, the lighting and air intake of houses were basically from the natural environment, so the ancients attached great importance to the location and orientation of houses, and tried to build the houses in places with sufficient light and wind accumulation.
With the continuous progress of human science and technology, in modern society, people can improve the indoor phosgene environment through various technical means to a certain extent, without completely relying on nature. When the air convection is not ideal, the air velocity can be adjusted by fan and air conditioner, and the artificial light can be used to keep the room bright when the illumination is insufficient.
Don't dazzle the lights
The correct indoor lighting color design has become another important thing that people consider when decorating the house: in the family decoration, lighting design should not make people dazzled and the contrast is too big. Lighting design should be good at the relationship between light and color: color has a great impact on people's psychology and physiology, for example, blue can slow down heart rhythm, adjust balance and eliminate tension; beige, light blue and light gray are conducive to quiet rest and sleep, and eliminate fatigue; red, orange and yellow can make people excited and vibrate Work hard; white can make the blood pressure of patients with hypertension lower, calm; red makes people's blood pressure rise, breathing faster, when the lighting and home color perfect combination, our home will be more beautiful.
Color selection according to children's personality
Children's furniture color selection, but also to consider the psychological problems of children: is usually we say according to different children's personality design color collocation: personality, gender, age are the starting point of the design, if the child is more mischievous, then in the color to choose static color system, such as blue, green coal, after singing into the room, his mood can be calmer, if the child Son itself is relatively introverted, which can use some relatively warm colors, such as orange and pink, so that after he enters the room, there is an emotional release. Through these details, children can do a little psychological counseling in the room, which is conducive to their healthy growth.
Living room lighting should take care of health
The core of home lighting is a light health problem: light is related to our healthy life. Experts believe that: the so-called light health includes two aspects: one is that lighting must meet the functional requirements of the place, that is, whether the light is bright or beautiful; the other is that lighting must meet people's psychological requirements, such as the influence of color temperature and brightness on people's mood, and whether the light and shadow are harmonious or not. Unreasonable lighting tools, improper lighting methods, will have a great impact on health: bright light, can change the internal clock of the brain, control sleep. However, working under the light for a long time will reduce the absorption of calcium by the human body; if the light wave is too strong, abnormal cells will increase and normal cells will die. We must pay attention to this.
Harm of sleeping with light on
Nowadays, some young parents are used to letting their babies sleep in the light when they are active at night. In fact, this is harmful to the health of the baby.
Scientists have found that any artificial light source can produce a subtle light pressure. The long-term existence of this kind of light pressure will make people, especially infants and young children, appear restless and restless, so that it is difficult to sleep. At the same time, let the baby sleep under the light for a long time, and then affect the reticular activation system, so that their sleep time is shortened, sleep depth becomes shallow and easy to wake up.
In addition, the baby long sleep under the light, will affect the normal development of vision. We know that the benefits of light out sleep lie in the full rest of the eyes and ciliary muscles. Long term sleep under the light, light on the eye stimulation will continue, the eyes and eyelashes can not get enough rest. This is very easy to cause damage to the retina and affect the normal development of vision for infants.
Young parents are advised to turn off the lights in the room when they are sleeping for the healthy growth of their babies. This is more important than keeping warm and quiet indoors.
