Why we all need some green in our lives - Deepstash
Green:The Universal Colour of Healing

Green, the mixture of blue and yellow, can be seen everywhere and in countless shades. In fact, the human eye sees green better than any colour in the spectrum.

In the Bible, meaning of colour green is immortality because green is obtained by mixing yellow (trials) with blue (Word of god). (The leaf shall not wither-psalm1:3)

Along with many other facts about this earthly colour, makes it an essential part of our everyday lives.



Humans are trichromats, meaning we perceive three primary colours: blue, green and red. The retina in a human eye can detect light between wavelengths of 400 nanometres (lowest-violet) and 700 nanometres(highest-red), a range known as the visible spectrum.

In the middle of the spectrum resides the colour green(around 555 nanometres). This wavelength is where our perception is at its best. Because of its position in the center of the spectrum, both violet and red light waves are enhanced and better perceived with the help of green waves.



At fist our ancestors lived in the forests full of greenary.As they scavenged for food, the ability to differentiate its colour among the other colours of nature evolved.

The evolution of eyesight and the increasing ability to detect colour with fine detail gave our primate ancestors an evolutionary advantage over other mammals who could not discern such differences as well.

Colour changes in leaves, fruits and vegetables can indicate age or ripeness and even offer a warning that something may be poisonous or rotten.

Today, we use this ancestral instinct at a farmers market or grocery store.



Bananas, though widely considered to be a yellow fruit, start off as green due to the presence of chlorophyl. Just as grass and leaves have chlorophyll to give them colour, so do fruits.

Located in the cells of plants, chlorophyl plays a crucial role in photosynthesis, allowing plants to harvest energy from sunlight and convert it into energy that the plant can use to grow.

The molecule absorbs blue and red light well while reflecting the green light that we see.



Natural environments, full of green vegetation, might help you live longer.

A 2016 study found that living in or near green areas can was linked with longer life expectancy and improved mental health in female participants.

After the eight-year study was completed, the data revealed that participants who lived in the greenest areas had a 12% lower death rate than women living in the least green areas.

With more green space came more opportunity to socialize outdoors and the natural settings(compared with residential regions where plants were sparse) proved to be beneficial to mental health.
