If you can’t wake up in the morning, and in the evening, on the contrary, you toss and turn in bed in an attempt to fall asleep, this is a sure sign that, most likely, it’s time to change the lamps in the house. Our productivity, mood and well-being in general depend on light. The eyes are very sensitive to the light entering them, transmit this information to the brain, which, in turn, produces certain hormones. For example, melatonin to relax and fall asleep, and cortisol to cheer up and wake up. Our brain will work much more productively if we turn on the right light temperature at the right time.

Color temperature - a physical concept, expresses the intensity of the radiation of a light source and is measured in kelvins (K). Information about the color temperature is always indicated on the packaging of the lamp or luminaire.



Light with a lower color temperature has a yellow tint, such light is closer to the red spectrum. Light with a higher color temperature has a white tint and is closer to the blue spectrum. The table below will help you understand how a particular color temperature looks in nature and how best to apply it in life.

Temperature, K	Hue	In nature	Application
2,500–3,000	Warm Orange	Sunrise	Adds a cozy atmosphere
3,000–4,000	Warm yellow	The sky 2 hours after sunrise and 2 hours before sunset	Relaxation
4,000–5,000	Neutral white	Midday Sun	Improves performance
5,000–6,500	Blueish	Cloudy sky	To display items

Which color temperature to choose for lighting your home depends on what you want to achieve from lighting: create a cozy and relaxing atmosphere, or, conversely, stimulate yourself to be active. These tasks may differ depending on the room.

Task: to create a cozy and relaxing "evening" atmosphere

Solution: luminaires with a low color temperature - 2700K, having an orange tint, are suitable for this purpose. They are recommended to be installed in home "resting places" - in the bedroom, living room, above the dining table. Most often, pendant lamps, sconces, bedside and floor lamps become the source of such subdued light. Those. It's more of an accent light than a main one. You should not get carried away with too dim light - the load on the eyes increases, which can lead to headaches.

Task: to choose a color temperature for the main lighting in the house

Solution: for the main lighting of most rooms, lamps with a color temperature of 3000K are intended, their light has a pleasant yellowish tint, it is not too relaxing, but not too invigorating. Such light adds coziness, comfortable for the eyes.

Goal: improve efficiency

Solution: Cool neutral white light from 4000 to 5000K will be an excellent tool to improve productivity and performance. It is closest to bright daylight, which helps it increase concentration and relieve fatigue. This light is suitable for the study, office, working area in the kitchen, reading area. For an office, for example, you can use ceiling lights, for a kitchen - an LED strip, for a reading area - a floor lamp with a corresponding lamp.

Task: to profitably show a product in a store or an exhibit in a museum

Solution: light with a bluish tint and a color temperature of 5000-6000K will cope with the task. In the home interior, such light is not used - it is too harsh and irritating to the body. But to show in all its glory a ring in a jewelry store or a picture in a museum - this light is perfect for this.

In order not to disrupt your own circadian rhythms, sleep well and feel better in general, the temperature of the light around you should change during the day. The cold daylight of the office is best replaced with warm and relaxing at home. To create at home zones with light of different color temperatures, you can do the following:

Use multiple light sources. For example, the main lighting with a temperature of 3000K, a floor lamp above the table or a bedside lamp with 2500K, a desktop table lamp with 4000K. The main thing here is not to get too carried away, so as not to arrange a light show from the interior - too sharp color transitions can irritate the eyes and look unstylish.

Set dimmable light sources. They are more expensive, but they allow you to quickly change the color temperature of the fixtures in the house.



By the way, pay attention to your mobile. It will be useful to switch the color temperature of the screen - make it lower in the evening and especially before going to bed, higher - during the day. Just like with interior lighting, this will either help you relax and fall asleep easier, or, on the contrary, cheer you up. Special "night" modes in many smartphones are built-in automatically, if not, you can use a special application (for example, Bluelight Filter), which blocks blue radiation.

Wish you cozy interiors and balanced feelings!
