With light, comes life.

We are very certain that you are reading this in a well-lit environment, or just in natural daylight. Research shows that an adequate amount of light improves our mood and energy levels, while terrible lighting brings about deficiencies and mental ailments like depression. Not to mention, the amount and type of lighting available directly affect concentration, appetite, mood, and many other aspects of daily life.

It is important to note that natural daylight stimulates our brains to produce the ‘feel-good’ hormone serotonin, which makes us feel alert and motivated. Then as light levels begin to fade in the evening, our bodies respond by producing the hormone melatonin, to help prepare us for sleep. If you’re anything like us, you know changes in the weather and the seasons can have a significant effect on our state of mind. Just as we can feel more tired and unmotivated on a cold and gloomy day, so when the sun comes out the metaphorical clouds also seem to lift and we feel happier and more optimistic!

As lighting dealers, we at Rossa fully understand the importance of appropriate lighting. And our team is always very ready to help our customers understand this. The wrong type of light in the wrong place can bring about negative results in terms of both mood and revenue. And vice versa. 

In general terms, we recommend brighter and stronger lights for the morning and during the day, while dimmer lights are recommended for night. 


The reason for this is because, warm/natural lights make the environment feel more welcoming and relaxing, while cooler lights make the environment more stimulating. They make us feel more alert, more focused, and can increase our productivity levels. 

Blue Lights

Blue lights are what we refer to screen and mobile phone lights. Research shows that blue lightsreduce levels of the sleep-related hormone melatonin, making us feel more awake. Computers and mobile screens emit a lot of blue light, so that last email check before bed can easily lead to an extra hour of YouTube binging. 

But when used intelligently, blue light can be ideal for those spaces where the mind needs to work at full speed, such as meeting rooms and factories, where high concentration is expected.


Yellow Lights

These correspond more to dusk and dawn – times when the body is generally more relaxed. If you think about it, humans weren’t originally exposed to high-intensity lights at night, but simply to the light of the moon and the fire. 

Weak, indirect, and warm lighting tends to make environments quieter and people more relaxed. Although this may not be a good choice for a work environment that requires efficiency and productivity, it may be beneficial for a restaurant, a rest area, or a bedroom. 

Experts agree that taking advantage of sunlight during the day and avoiding direct exposure to cold or blue light at bedtime can improve quality of sleep and positively affect people’s well-being and productivity. And although it’s impossible to control the lighting of all the environments and spaces that we will inhabit, being aware of the impacts of lighting on our body can make us think twice about some of the choices we would otherwise make in a heartbeat – whether it be buying that lamp for sale in the supermarket, or even just checking our phone one last time before bed.

Thank you.
