Light in our lives plays an important role. According to biologists, 90% of the data is perceived through visual channels. It is for this reason that moderate light favorably affects the vital activity of all living beings. Lighting is not only an important component for the operation of the visual analyzer, but also affects the general condition of the body. In addition, light can positively or, conversely, adversely affect plants and animals.
Lighting value
It is important to realize that lighting has the ability to visually reduce or increase the size of the room. Not only the aesthetic appearance of the room depends on the light, but also the well-being of those who are in it. Incorrectly selected lighting can cause overwork. If the light in the room is too bright, its inhabitants are prone to neurosis and vision problems.
Life without light or with a minimal amount of it can lead to vitamin deficiency, a decrease in the activity of immunity and weakening of the body, as a result of which resistance to colds and other diseases decreases. In addition, disability decreases and the general condition worsens.
The role of sunlight in human life
Does everyone know what is the role of sunlight in human life? Perhaps its value is invaluable. Thanks to sunlight, we are able to distinguish objects around us. It is from interaction with natural light that vital Vitamin D is synthesized in the body. Thanks to light, calcium and phosphorus are also absorbed.
Sunlight plays a fundamental role in our life, it affects our well-being and state of mind. Its lack can cause apathy, depression and poor health. Sunlight has a detrimental effect on many pathogenic bacteria and is considered a natural antiseptic.
Varieties of lighting
Light is electromagnetic radiation visible to the human eye with a wavelength of 380 to 780 nm. It is natural, artificial and combined. The sources of natural light include the Sun, the Moon.
All that man has created for lighting is artificial light. Today, 5 types of such lighting are used:
- incandescent lamps;
- halogen incandescent lamps;
- fluorescent lamps;
- gas discharge lamps and LEDs.
Light in medicine
Surprisingly, from the ancestors we got the pineal gland - a place that is in the brain. It is interconnected directly with the eyes. As soon as the light level decreases, the pineal gland produces sleep hormone, which slows down the active processes in the body and warns of "hibernation". The presence of such a hormone can be destroyed by interacting with natural light, which, of course, is not enough in winter. In such cases, doctors recommend consuming foods that are high in vitamins, do not save energy and wear bright clothes.
Few people know, but in some European hospitals they adhere to a certain concept. Its creator is Van der Heide. The scientist believes that for a faster recovery for absolutely every patient, you need to choose your own light level. The researcher even created a “smart system” for this, which gradually illuminates the room in the morning and emits rays of different brightness. It is proved that such manipulations positively affect the state of nerve cells and the general well-being of a person. Numerous studies have shown: due to the interaction of the right light with the human body that is being treated, positive changes are observed in its state.
The researcher proved that correctly selected light in human life is an important component for the development of the body and brain activity.
A bit about education
From early childhood, it is important to understand exactly what benefit the sun and lighting bring to us. This year, all the schools of the Russian Federation held a class hour "Light in your life." At it, the children explained the full benefits of light and talked about the most famous scientists who were one of the first to study lighting. In addition, the poems of the greatest poets who exalt the light rays were presented. From this we can conclude that their benefits were discovered many years ago.
Lighting for baby
Light in the life of a child plays a very important role. Experts believe that its development depends on lighting. From early childhood, only proper lighting should surround the child. If you have not taken this issue seriously, you have every chance to earn a large number of health problems. As we said earlier, light can be natural and artificial. Let's take a closer look at what kind of lighting should be in the children's room.
Natural light in a children's room
Natural light in our life is a very important factor in the prevention of various diseases. When choosing a room for a child, remember that the most lighted rooms are located on the south side of the house. The morning rays will wake the baby. This has a positive effect on the nervous system. Biorhythms of children in such circumstances begin to work correctly, in accordance with the laws of nature. This is important for the development of habits, lifestyle and psychological state of the child.
In the event that there is no suitable room for the child, poorly lit rooms will need to be supplemented with artificial light sources, and a baby bed should be placed opposite the window.
Artificial light in a children's room
Artificial light in a child’s room can be divided into daylight and night lighting. When choosing lamps in a nursery, it is necessary to pay attention to the fact that crystal lamps are categorically not suitable. They create a large number of multi-colored flares that irritate the visual apparatus of the child.
The best choice for the nursery is horizontal light sources with a matte finish. Due to this, the lighting in the room will be scattered and thereby favorably affect vision and well-being.
Light in our life is necessary not only during the day, but also at night. Another important component of any children's room is a nightlight, which is located at the head of the bed. The benefits of such a light source are obvious. Thanks to the night lamp, the child will feel comfortable falling asleep. It is recommended to choose night lights with the ability to control the level of radiation.
The role of light in animal life
Lighting affects the development of all living things on the planet. Light in the life of animals plays a rather important role. It has long been noticed that, for example, for hens, good lighting is the most important component. Feathered eyes are very sensitive to daylight. In the spring, when interacting with bright light, a signal enters the brain, and they begin to lay eggs.
Without exception, all adapt to the length of the day. There are types of long and short day. A striking example is goats. An increase in the level of gonadotropin occurs when the day is shortened, namely in the second half of the year. From September to December, goats are fertilized. The duration of their pregnancy is about five months. In time for spring, when the young grass sprouts, goats appear. Thanks to this, it can be concluded that absolutely all animal vital processes are associated with daylight hours.
The relationship between lighting and the sexual cycle of cows is quite curious. There is even a term such as climate-control childlessness. The best ratio for the life of cows - 16 hours of the day and 8 - nights. This ratio occurs in different countries at different times of the year. We have the end of April and May. It was at this time that cows increased hormonal status. It is an important criterion for mating animals.
The reaction to a change in daylight hours can be attributed to many processes in the life of animals. For example, molting in mammals and feather change in birds. Scientists have proven that animals living in open areas have a protective layer of skin. It allows you not to overheat in hot weather.
Lighting in plant life
Light in plant life is an extremely important component. Lighting is necessary to create chlorophyll. Also, thanks to light, plants have a great influence on gas exchange processes, protein synthesis and cell division. It is lighting that regulates the timing of flowering and fruiting. There are three categories of plants, depending on light sensitivity:
- photophilous, which develop only in the presence of good natural light;
- optimal, which can bloom and develop both in the shade and in the light;
- shade-loving, who do not tolerate direct sunlight.
Few people know, but there are even plants that, with the slightest shift in daylight, will develop more slowly and cease to bloom. In plants, during the daytime, the movements of the light phase of photosynthesis are realized , and at night - the dark. Photoperiodism in plants is associated with the manifestation of phototropy - the movement of plant leaves toward the sun, for example, the shift of the head of a sunflower throughout the day according to the movement of the sun.
To summarize
The light in your life is one of the most important factors of life. Properly selected lighting in the house will allow you to get rid of depression, headache and chronic fatigue. As we said earlier, in addition to health effects, light allows you to visually increase or decrease the room.
Scientists have proved that too bright, or, conversely, dim light entails problems with vision and performance. It is recommended that you fix the lighting problems in a timely manner and enjoy your well-being right now. Be healthy!
