The correct lighting of an environment and the use of colored LEDs can affect both our mood and our body. Lights and colors have specific frequencies that our eyes recognise and processes with very interesting effects.
Let’s think about, for example, the dancing fountains with colored lights or the emotional showers of the wellness center. Lights, colors and water are wisely used to create feelings of well-being, relaxation and pleasure in us. They take inspiration from chromotherapy, an alternative medicine that studies the effects of colors on our body.
According to it, through the correct exposure to various colors it would be possible to cure depression, stress, physical and mental weakness, pains and, for some, even some pathologies. From a scientific point of view, such benefits have never been demonstrated, but some correspondences between light, color and physiological reactions are undeniable.
Everything starts from our eye: to a specific visual stimulation, the cells send impulses to the hypothalamus, which starts and produces different types of hormones. This is the basic principle which regulates wake/sleep activity: at dusk, our body no longer perceives light and starts producing melatonin, a natural hormone that prepares us to sleep. In the morning the level of this substance is very low and the body, stimulated by the lights of dawn, begins to produce cortisol, which gives us energy to face the day.
The same principle can be applied to the range of colors, scientific studies have shown how for example the red light affects our heartbeat, increasing its pace, while the blue light reduces it. Each color would have precise effects on the human body, red would stimulate physical and intellectual activity, blue would be calming and relaxing, yellow would increase attention and so on.
How and in which quantity these phenomena affect man, still has to be verified, but some collected data are significant.
In 2009, during the use of blue LED lights in the Tokyo subway, the suicide rate decreased by 74%: a single episode too isolated to represent a scientific fact, but still an interesting case.
Despite the fact that science has not yet definitively expressed itself on these researches, it is undeniable that LED lights with certain sequences of RGB color, even better if associated and amplified by the effect of water, create certain reactions and emotions in us.
Being able to take advantage of these benefits is simpler than expected; a fountain, from inside or outside, with the correct sequence of colors and lights is able not only to embellish an environment, but to help create the right atmosphere to create a situation of rest and relax.
