Blue: calmness, serenity, peace

It's also associated with wisdom, creativity, and spirituality. Light blues are serene and can help with insomnia, while too much exposure to dark shades can trigger feelings of sadness, loneliness, or lethargy .

This creates abnormally high exposure to harmful blue light wavelengths which are much higher than we would receive naturally outdoors from the sun. These high levels of blue light cause an increase in our stress hormones cortisol and adrenaline which leave us feeling highly stressed, irritable, and anxious.

Blue Light and Your Skin

Research shows blue light from electronic devices can lead to changes in your skin cells, including cell shrinkage and death. These speed up the aging process. Even exposures as short as 60 minutes can trigger these changes. Too much blue light could also lead to pigmentation.

How does blue light affect children? ›

Exposure to high levels of blue light could be causing changes in your child's brain. Children who spend more than two hours using screens — like smartphones, tablets, and gaming devices — have been shown to score lower on thinking and language tests (9).

Wavelength of blue light

Blue light has very short, high energy waves. In fact, they're only slightly longer and less powerful than UV waves, which are too short for people to see with the naked eye. Health experts have warned against the harmful effects of UV rays, which can damage your skin and your eyes.

It's certain that blue light in the 380–400 nm range is problematic, although the risk seems to lessen somewhat toward the top end, at 500 nm.

When you stare at a screen for hours at a time, whether it is a computer, TV, phone or tablet, you are exposed to blue light from the device.

However, inappropriate lighting exposure (especially from artificial sources of blue light in the evening or at night) may lead to harmful effects on health [2]. Due to its high energy, blue light can cause and accelerate photochemical reactions and retinal cell damage [3].
