How does blue light affect sleep?
First, let's take a quick look at the right sleep pattern.
The body perceives day and night through the constant shift of the sun , and regulates all hormone secretion through the biological clock.
It works to keep you awake and focused during the day, and deep recovery and restful sleep at night.
The phenomenon of falling asleep and waking up through the hormone secretion process at the right time is called "circadian rhythm" . What is Circadian Rhythm?
The correct circadian rhythm is
During the day - it smoothly secretes cortisol , serotonin , dopamine and other essential hormones to help us wake up and focus.
At night - when the sun goes down and it gets dark, melatonin is released, essential for restful sleep and deep recovery.
A dark night is essential for the secretion of the sleep hormone (melatonin).
The circadian rhythm collapsed through excessive artificial light at night,
It suppresses the secretion of melatonin , which interferes with the secretion of a hormone essential for growth and recovery, and this pattern repeats itself, leading to insomnia !
Modern society cannot live without artificial light at night.
From LED bulbs and fluorescent lights to cell phones and computers , these are all sources of blue light, the dominant wavelength of artificial light.
And this blue light sends a signal through your eyes to your body that you need to be awake, suppressing your sleep hormones!ﾠ
In particular, exposure to artificial blue light 1-2 hours before bedtime has a fatal effect on the body in the long term.
How does blue light adversely affect sleep?
Blue light is a high-energy source of wavelengths.
Higher energy means that light travels deeper into the brain through the eyes.
What happens when you receive artificial blue light at night instead of during the day:
- High-energy blue light passes through the eyes and reaches the brain.
- The brain recognizes that it is morning time and sends a signal to every cell in the body to be awake.
- Hormones that should be secreted during the day continue into the night.
- Restoration, regeneration, and growth cannot take place properly because you cannot get deep sleep.
- As this process is repeated, various diseases and chronic fatigue are encountered through a vicious cycle.
Blue light is necessary during the day when we need to be awake,
At night, you need to give your brain and body clear signals that it's time to sleep .
Our eyes cannot detect the difference between natural and artificial blue light.
The brain only receives information from high-energy sources through blue light and sends signals to the human body.
However, before going to bed, blue light artificially brightens the dark night necessary for the secretion of melatonin (sleep hormone) and becomes the main factor that adversely affects sleep.
Then, what practices can effectively block blue light at night?
Wake up at sunrise , just like our ancestors did,
Meet the darkness in line with the sunset ,
If only fire could be used as a source of light at night,
You will be able to maintain an optimal circadian rhythm and sleep pattern.
However, for modern people who cannot realistically do this,
Lucid Eyes has developed glasses that block 100% of blue light so that modern people can set the circadian rhythm right away .
Lucid Eyes yellow day lenses are formulated to block 95% of the most harmful range of artificial blue light while allowing harmful colors necessary for perception, functionality and health to pass through.
Lucid Eyes red night lenses block 100% of artificial blue and green light that has been shown to be unhealthy and disruptive to sleep patterns and circadian rhythms.
