Light and its color temperature have a major impact on our health. A healthy life also includes healthy light-especially in our eyes. Although daylight is the healthiest, there are now LEDs that can create an ideal lighting atmosphere according to the time of day and season. The following medical discoveries have been incorporated into light sources and luminous bodies, and are revolutionizing our daily lives.
The light color or color temperature of lamps, LEDs, or electrical equipment has a great influence on our happiness and even health. A typical example in practice: After a long night watching TV, do you have difficulty falling asleep? Even if this is not a very exciting movie?
This is usually due to the blue light emitted by most televisions: the cool blue light sends a signal to our body that it is sunny today. Looking at the smartphone screen for a long time before going to bed may be worse. Because mobile phones also have blue light, and this light is closer to the eyes, often only 30 centimeters away. There, on the retina, some receptors respond sensitively to the color temperature of light, helping to determine our rhythm of life.
How does the color temperature of light affect our body?
Light affects not only the visual cells in our eyes but also the so-called ganglion cells. Under the stimulation of light, they release messenger substances, readjust our internal clock and regulate a large number of processes in the body: pulse and body temperature, and wakefulness. If the light is blue and bright, then the serotonin hormone will increase, which will send a signal to our body: to be active! If it gets dark, or the light emits a warm red hue like a campfire, this means relaxation for us: the sleep hormone melatonin is released.
There is no evidence that if we ignore these rhythms for a long time in our lifestyle, it will be harmful to our health. In principle, human beings, therefore, depend on light, just like the plant world. It wasn't until 2017 that the Nobel Prize Committee awarded medicine prizes for studying such internal clocks.
Housing advice: which room to use what light?
Fortunately, lighting technology has made significant progress in the past few years. Medical knowledge and medical knowledge of color temperature implemented in lighting products: the use of modern LEDs can produce many light colors. You can see this on the packaging. There, in addition to power (in watts) and brightness (in lumens), the color of the light emitted is also noted.
Warm light is more suitable for the lighting in the bedroom or the living room, neutral or cool, rather than the workspace kitchen lighting and corridors. Light colors are also usually given in "degrees Kelvin": a value of about 3,000 degrees corresponds to a fairly warm light, and a value of about 5,000 degrees (or higher) is quite blue and cool.
For some light sources, these colors can be specifically affected and changed according to the time of day. Sunmory floor lamps already exist in homes and offices. It is a kind of light in line with human rhythm. The concept of biodynamic lighting is used in the workplace to improve employee happiness and productivity. For the Industrial Floor Lamp, compared with other transparent glass lampshades, the frosted hanging glass lampshade filters the strong light into soft natural light, protects your eyes from direct sunlight, and creates a warm and comfortable atmosphere for the home. Smart sockets that support Alexa, Google Home Assistant, or Apple HomeKit can be used together.
