What is circadian rhythm?

Circadian rhythm, a biological clock, refers to all changes that occur periodically in our body in accordance with the change of day and night in a 24-hour cycle.



The reason why circadian rhythm is important is because it is responsible for producing serotonin, dopamine, growth hormone, testosterone and other hormones essential for health in the body.


Above all, the circadian rhythm controls the cycle and depth of sleep .



According to the body clock, the sympathetic nervous system is activated during the day to help you stay awake, and the parasympathetic nervous system is activated in the evening to help you fall asleep.


In other words, in order to live a healthy life, it is most important to be able to sleep deeply through a regular pattern.




Blue light is the most damaging cause of circadian rhythm!



Blue light, a high-energy wavelength at night, suppresses the secretion of sleep hormone (melatonin) and sends a signal to the brain that it is still daytime, signaling the body to stay awake.


This leads to insomnia, poor sleep quality, sleep cycle disorders, and ultimately becomes the root of all diseases!



So how can circadian rhythm be improved?

It's important to signal to your body that it's morning by going outside immediately after waking up and starting your day with sunlight.



Spend as much time as possible in natural light during the day ,


Stay as dark as possible at night and stay away from harmful blue light.


Spending time outdoors should be a priority, but just in case you can't avoid it , you'll need Lucid Eyes Premium Blue Light Blocking Glasses!



When should I wear which glasses?


AM/PM - Day lenses protect your eyes and body by blocking 95% of blue light from indoor lighting.




Evening - The night lens blocks 100% of blue and green light, allowing you to get a deep, comfortable sleep.

Day lenses are designed to block blue light emitted from the screen while allowing harmful colors to pass through.


Night lenses block the entire spectrum of blue light/green light, which has been proven to adversely affect sleep.



Now is the time to understand how much light affects the human body.


A healthy life begins with creating a light environment.


Correct your circadian rhythm with Lucid Eyes and experience deep sleep and a healthy life.
