Difference between sunlight and artificial light

Every color of natural light has a purpose and role.

Sunlight constantly fluctuates depending on the time of day, time of year, and location on Earth.

All of these changes and the harmony of light wavelengths play an important role in maintaining the circadian rhythm correctly.

As you can see in the photo above, all wavelengths of light are highest during the day (noon) . The reason is that this is the best time to be active and productive.

In the evening , as sunset approaches, the temperature of all light gradually decreases along with the intensity of blue light.

At night, until the invention of the light bulb in 1979, the only light source available to mankind was fire.

Red light (infrared ray), the main wavelength of fire, is a wavelength of light that minimizes inhibition of melatonin (sleep hormone) secretion and does not interfere with sleep.

However, as computers, smartphones, and indoor white lighting became popular,

Everything has changed .

Artificial light is light that is distorted and unbalanced when viewed from a natural perspective.

And distorted blue light, the main wavelength of artificial light, has a fatal effect on sleep .

All colors of light play a role in sending signals to the human body .

Blue Light - Awakening

Green Light - Activities

Yellow Light - Stable

Red Light – Recovery

Blue light increases in the morning and afternoon when sunlight is the right time for us to concentrate and be active.

As the sunrise approaches, the blue light begins to gradually decrease, and as the sun sets, a change that is rarely seen is visible.

However, artificially looking at blue light at night tells the body that it is daytime, and this is an unsuitable wavelength for the night when one needs to relax.

In other words, blue light at night is no different from a stimulant that signals the body to be awake.

Blue light can have detrimental effects on health and sleep when exposed to it in the evening when it is not balanced with other colors of light or when it is out of rhythm with nature .

While sunlight varies in balance across the entire wavelength range, artificial light emits distorted wavelengths of light that do not change with time.

Everything in nature is in balance and harmony .

Living with distorted wavelengths of light and a biased perspective causes disease and pain.

Indoor fluorescent lights emit excessive blue light during the day, which is a major cause of chronic eye fatigue and lethargy, and blue light emitted by cell phones and electronic devices at night is the cause of sleep disorders and insomnia.
