The new frontier of the lighting sector has a specific name – Human Centric Lighting<\/strong><\/a> \u2013 and specific areas of application, such as school and aged care homes.
\u201cOffice lighting<\/strong>\u201d topic is also well represented among the human centric designing subjects: the working spaces represent those places where a human being spends most of her\/his time and therefore they deserve to be studied.<\/p>\n\n\n\n

Humans and nature <\/h2>\n\n\n\n

Nature has always marked our biological rhythms<\/strong> through the sunlight exposure or not. Within 24 hours, the light-dark cycle sets the pace<\/strong>, giving time to our body for a well-defined cycle of activity and rest that has cadenced the human life from the beginning.<\/p>\n\n\n\n

So, the day-night cycle is a key factor that controls the hormone release, the sleeping and waking
patterns, along with the blood pressure<\/strong>.<\/p>\n\n\n\n

The blue light<\/h3>\n\n\n
\n
\"\"<\/figure>\n<\/div>\n\n\n

It has particularly been shown that a light colour<\/strong> can make a difference: a lighting stimulus of specific blue<\/strong> frequencies at night signals to our brain that it is still daylight<\/strong>, inhibiting the melatonin production and making harder to sleep. Therefore, the exposure to this light in the evening is potentially harmful for our health because it desynchronizes our biological clock<\/strong> at the base of life on Earth (the circadian rhythms). During daylight hours, the correct usage of the same light can provide positive effects on people\u2019s performances instead<\/strong>.<\/p>\n\n\n\n

MOOD and MEMORY <\/h4>\n\n\n\n

It has always been quite clear that light has effects on mood<\/strong> too: just think about the long winter days, when the lack of light brings bad mood<\/strong>, irritability and energy lack, especially during the delicate transition from a season to another.<\/p>\n\n\n

\n
\"\"<\/figure>\n<\/div>\n\n\n

The chronobiologist Samer Hattar<\/a> from John Hopkins University has carried out a study recently where he has shown that light activates particular eyes cells<\/strong> (intrinsically photosensitive retinal ganglion cells or IPRGC) that, in turn, transmit signals to the brain centres in charge of our mood<\/strong>, learning<\/strong> and memory<\/strong>. That is thus light to regulate the behaviours related to mood and cognitive functions.<\/p>\n\n\n\n

The advent of the electric lighting<\/strong> enabled people to carry out daytime activities after sunset, introducing night work or on shifts<\/strong>. Anyway, that change has brought other consequences: in fact, flipping days for nights<\/strong> can lead to depression<\/strong>, along with memory issues<\/strong>. It is noteworthy that the results of the experimentation show the onset of learning problems just after <\/strong>finding mood disorders.
The chronobiologist\u2019s research highlights that the major cause of those alterations is not much
about the lack of sleep, but they are due to the exposure to the bright light of the light sources<\/strong>.<\/p>\n\n\n\n

LIGHT THERAPY <\/h4>\n\n\n\n

Therefore, it is no coincidence that light is increasingly being used as a real therapy: Michael
Terman the author of Chronotherapy, has highlighted that the change of light during the various
phases of the year or the change of lighting inside the buildings can affect the human behaviour<\/strong>.
The research carried out shows that 53,3% of people with seasonal affective disorder (SAD) have
benefited from a significant improvement of depressive symptoms by the light therapy (Light
Therapy<\/a>).
So, the blue light is not only harmful: if it used at the right time of the day, it can be a real ally to
ensure an individual\u2019s well-being<\/strong>.<\/p>\n\n\n\n

HUMAN CENTRIC LIGHTING IN THE WORLD <\/h4>\n\n\n\n
TOKYO <\/h5>\n\n\n

\"\"<\/figure>\n<\/div>\n\n\n

In Tokyo, blue lights<\/strong> have been installed in the subway<\/strong> and at the railway stations of the city in order to hinder the high suicide rate.
The outcome has been amazing<\/strong>: the introduction of these installations has reduced the deaths by 84<\/a>%.<\/p>\n\n\n\n

MOSCOW <\/p>\n\n\n\n

In Moscow<\/a>, the latest generation subway<\/strong> has given prominence to lighting too. Trains equipped with
LED lights adapting to the time of the day<\/strong>: a cooler light during the daytime that gradually becomes
warmer as the evening advances.
The system, coherent with the basic principles of human centric lighting, enables the commuters to
reach high levels of vigilance and productivity<\/strong>. The night lighting, lower on the Kelvin scale, fosters
the melatonin production for a quality sleep, instead.<\/p>\n\n\n\n

Flexible spaces and a dynamic light <\/h2>\n\n\n
\n
\"\"<\/figure>\n<\/div>\n\n\n

Times change and, along with them, the traditional office work too. Pandemic has speeded up the transformation, making office activities increasingly more dynamic and flexible. Working models are changing and, along with them, their spaces<\/strong>: the static workstations, where each place was assigned in a strict and inflexible way, have been becoming a thing of the past. The fragmentation in place is going to give rise to real work areas.<\/p>\n\n\n\n

Therefore, offices are changing into a multifunctional environment<\/strong>, where we can make room for interaction and human connection, along with production: technology and architecture have to help to provide answers to the new worker\u2019s needs<\/strong>.<\/p>\n\n\n\n

A resilient design <\/h3>\n\n\n\n


In an increasingly evolving work world, lighting design has to be able to adapt to change<\/strong>.
Human Centric Lighting solutions are combined in a holistic way to ensure the emotional<\/strong>, biological<\/strong> and visual<\/strong> effects of light.
The lighting impact affects a variety of factors:<\/p>\n\n\n\n
