Conclusion: Fitter into the day
Especially in the cloudy autumn and winter months, many people are struggling to get into the corridors. It's still dark when you get up and when you get out of work, it's already dark again. In addition, the sun rarely shows its radiance. But there are devices that brighten the day with artificial daylight or artificial sunlight: Daylight lamps and day-light alarm clocks. These not only combat fatigue, but also promote concentration and improve the mood.
What was the result of a daylight lamp?
The reason for fatigue and lack of energy can often be a high melatonin and a low serotonin level, caused by too little sunlight. Too much melatonin is responsible for making us feel tired. Too little serotonin, which is also considered a lucky hormone, negatively influences a person's mood. In order to alleviate the negative effects, many people benefit from an increased supply of artificial daylight. This stimulates, like natural sunlight, the formation of serotonin and lowers the melatonin value. For this reason, daylight lamps help healthy people to become more alert, while the luminaires help to combat a number of health problems.
Daylight lamps are like conventional lamps in living room, bathroom or kitchen. There they illuminate the rooms for working or reading optimally. In addition, healthy people receive an energy boost and get fit for the rest of the day when they are on for a period of time, such as during breakfast or drinking coffee. The light must stand directly in front of you and shine on you so that it has an effect.
A daylight lamp is also suitable for light therapy, which is used for medical purposes. Light therapy helps, for example, against winter depression, which accompanies many people through the cold season. This form of therapy is also an effective remedy for skin diseases such as psoriasis, migraine or sleep disorders.
To sit in front of a normal lamp, which is not explicitly marked as a daylight lamp, is useless by the way. Normal artificial light is too weak to stimulate physical processes.
How does a daylight lamp work?
Daylight lamps simulate sunlight in terms of brightness, spectral composition and color temperature of light.
The brightness is usually in lux by the manufacturer. This unit of measurement of illuminance is used to determine how much lumen (luminous flux)² falls to a given area in meters: Lux (lx) = lumen (lm) / square meter (m²).
Most daylight white light bulbs are 10,000 to 25,000 lux. To change the hormone balance, at least 10,000 lux is required. By comparison, 10,000 lux corresponds to a shady spot on a summer day, 20,000 lux to a covered summer day.
Note that the light intensity decreases as the distance to the light source increases. Therefore, you should observe the optimum distance to the daylight lamp, which is usually found in the operating instructions. For example, at a light intensity of 10,000 lux, a manufacturer recommends a distance of 15 to 20 cm.
In addition, a corresponding spectral composition is necessary, which reproduces the natural light. This is made up of light waves, which have different amounts of energy depending on the wavelength and which people perceive in different colors. The color spectrum visible to humans ranges from short-wave violet (400 nanometers) to long-wave red (700 nanometers). In addition, there are UV rays (290 to 380 nanometers) and infrared rays (700 to 770 nanometers). They are also part of light, but not visible to humans.
Many daylight lamps generate artificial daylight with the help of three light colors. Other luminaires, so-called full spectrum lamps, use all seven colors of the rainbow to produce the corresponding light.
Practical advice
Despite its spectral composition, the proportion of UV radiation in full-spectrum lamps is usually significantly reduced for everyday use. This prevents sunburn or long-term skin damage. For this reason, they are not suitable for stimulating vitamin D production in the body, as is the case in natural daylight. In the case of vitamin D deficiency, special luminaires with UV radiation are therefore used - preferably after consultation with a doctor.
The color temperature is another criterion for daylight lamps. These must have a color temperature between 5,300 and 6,500 Kelvin. People perceive this light as bluish-white.
How long should you use a daylight lamp?
Depending on the level of the lux and the intended use, the recommended service life is different. If the lamp is intended for light therapy, manufacturers recommend a minimum seat distance and a minimum duration of use. Depending on the light intensity, the distance is usually less than 50 cm and the time is between 30 and 90 minutes. The lamp works best during the day, for example at breakfast directly after getting up or at afternoon coffee. In the evening hours the light therapy with a daylight lamp should not take place anymore, since one should come to rest in order to fall asleep.
Purchase criteria for daylight lighting
Light intensity
Daylight bulbs are available for purchase with a light intensity between 2,500 and 10,000 lux. 10,000 lux is recommended for light therapy. Please note that the lux value has an effect on the duration and the distance between the seat and the lamp during light therapy. The lower the light intensity, the longer the duration and the lower the seat distance.
If the daylight lights are only intended to illuminate the room, a lower illuminance is sufficient.
Light bulbs
LEDs are usually used in the daylight lights. These are energy-saving and have a longer service life. In addition, classic fluorescent tubes are also installed in some models. In contrast to LED lights, the fluorescent tubes can be easily replaced. Manufacturers of daylight lamps offer corresponding replacement lamps for purchase.
Power consumption
Daylight lamps often consume a lot of energy for light therapy, since they have several integrated bulbs in order to achieve the corresponding brightness. Values of 45 or 72 watts are possible.
Dimmer
daylight lamps with dimmers are suitable for light therapy without dimming. In order to serve as room lighting, they can be dimmed to the desired brightness.
Mounting
Some lights have a stand to place on the table. Other daylight lamps also have a hanging attachment so that they can be hung up on a wall hook near the bathroom mirror, for example.
inclination angle.
A stand, which can be adjusted in several steps, makes the lamp more flexible. In this way, it can be adjusted to suit the height and size of the person. This means that the light shines directly on the one sitting in front of it.
Additional functions:
This includes, for example, timers that automatically switch off the device or the memory function. With it you can store light intensity and session duration and retrieve them comfortably by pressing a button.
What was the daily light alarm?
They are just so beautiful and suddenly the alarm clock will tear you out of sleep ungently. A start to the day that many people know and find rather stressful than beautiful. The so-called daily light alarm clocks wake up more gently, because they use light instead of sound in the first step.
Just when it's still dark outside and the natural sunlight is missing to wake up, day light alarms (also called light alarms or wake-up lights) promise a gentle start to the day. As with daylight lamps, the values of the hormone melatonin and serotonin play a decisive role in waking up. Accordingly, the light-minder whose light becomes Heller over a set period of time works. This simulates a sunrise.
The increasing light is intended to reduce the melatonin production, which is responsible for sleep. At the same time, serotonin production is increasing. This ensures that the stand-up is prepared slowly. You no longer fall back into deep sleep or REM phases, but remain in the light sleep or sleep phase.
Fall into bed tired at night and find sleep: The opposite is the case in the sleep function. Due to the weakening, artificial sunlight, the body distributes more melatonin and less serotonin. This way you get tired and falling asleep is easier.
Practical advice
In order to make the best use of the light alarm clock, its light should fall directly onto the face or eyes. It is best to test the Wake Up Light before using it for the first time. Lay down in bed and determine the location of the alarm clock so that it appears on your face at a distance of about 70 cm. For some devices, you can also set the light intensity or the alarm tone.
How does a light alarm function?
LED or halogen lamps are integrated in a daylight alarm clock. Depending on the device and setting, these start to simulate a sunrise about 20 to 120 minutes before the actual rise time. Some models start with dim white light that gets Heller until it is like daylight. Others start with red light and switch over orange and yellow to a white light - like a sunrise.
Color temperature and brightness are the most important factors in light-wackers. Whether you choose an alarm clock with white light or with the color of a simulated sunrise, it is a matter of taste. The only reason for waking up is the high amount of blue in the color spectrum, which is just as present in any colored light as in white.
It is important that the light is not too dark, so that the light can penetrate through the closed eye songs in any case. As a rule, day light alarm clocks have a luminosity of up to 300 lux at a distance of around 50 cm at the end of the wake-up phase. Values of over 100 Lux are absolutely recommended, optimum illumination is between 200 and 300 Lux.
Many Wake Up Lights provide the option to play music, sounds like wave noise or normal alarm sounds at the end of the wake-up phase.
Another feature that the light alarm clocks now often have is useful for falling asleep. If the alarm clock is set accordingly, it first lights up with bright daylight, which is gradually dimmed automatically. At a pre-set time, the lamp is reduced to a level that completely goes out. This is intended to help people who have problems falling asleep to put their body into sleep mode by reducing the light.
Purchase criteria for day light alarm clock
Wake-up phase
Make sure that the duration of the wake-up phase corresponds to your needs. There are models in which the wake-up phase can be individually adjusted. Often not by the minute, but in 15-minute intervals, for example. Other day-light alarm clocks specify the duration of the wake-up phase or offer a fixed number of possible times. However, a minimum recovery period of 30 minutes is recommended to allow the hormone level to change.
Sleep phase
you need not only assistance in getting up, but also in falling asleep, you should select an alarm clock that has a sleep or twilight function.
Light bulbs
are usually installed in light wackers as well as in daylight light bulbs LEDs. These are characterized by low energy consumption and a long service life.
Recovery phase
Make sure that the duration of the wake-up phase meets your needs. There are models in which the wake-up phase can be individually adjusted. Often not by the minute, but in 15-minute intervals, for example. Other day-light alarm clocks specify the duration of the wake-up phase or offer a fixed number of possible times. However, a minimum recovery period of 30 minutes is recommended to allow the hormone level to change.
Sleep phase
If you don't only need assistance getting up, but also falling asleep, it is best to select an alarm clock with a sleep or twilight function.
Light bulbs
As a rule, LEDs are installed in light wackers as well as in daylight lamps. These are characterized by low energy consumption and a long service life.
Illuminance
Optimum illumination is for Wake up Lights from 200 to 300 lux at a distance of approx. 50 cm. In order to get an idea of the brightness of this value: According to DIN 5035, for example, a lighting of 300 lux is required in sales rooms or meeting rooms. In offices with public transport or in the dining rooms of hotels there are 200 lux lights.
Color levels
Pure matter of taste - whether only white light in different brightness levels or color change as with a sunrise from red to orange to white. It doesn't matter for waking up. Because the blue content in the color spectrum of light alone causes you to become mumter. The amount of blue in each light is different.
Alarm time
If the rise time varies within a week, it is difficult to manually change the alarm time. It makes more sense to select an alarm clock that stores several alarm times. So it is no problem to program a later alarm time for the weekend, for example, than on the working days.
Alarm tones
In order to rely not only on the light as an alarm function, most day light alarm clocks also have alarm tones. Depending on the device, there is a built-in radio or USB port to play the playlist on your smartphone. In addition, alarm clocks provide a choice of classic alarm tones or play soft natural sounds such as bird chirping. So that no noisy radio station or wooden sounds of nature disturb the morning silence, you should pay attention to the corresponding sound quality.
Dimmable display.
Some people need absolute darkness to fall asleep and sleep through. Since the day light alarm clock is quite close to the face, the display can interfere with a bright time display. In this case, it helps when the display can be dimmed.
Function as bedside lamp
If the light alarm has a illuminance of 200 to 300 lux, it can also be used as a bedside lamp. For reading, for example, this level of brightness is absolutely sufficient.
Conclusion: Fitter into the day
The impact of light on humans should not be underestimated. This aspect is often not very much taken into account when you feel sleepy in the autumn and winter months. If you get out of your feathers early or feel tired all day, you should try a daylight lamp or a light-alarm clock. With the help of daylights you start your day more relaxed and waxed. Daylight lamps provide the necessary impetus for breakfast or throughout the day. In addition, they are also used for serious diseases such as winter depressions, migraine or skin diseases.
