Beyond the ordinary
To understand why mobile phones are harmful before sleep, we first must understand what melatonin is and how the body’s circadian rhythm works. Provided below is information on how these processes work.
What is circadian rhythm?
A circadian rhythm is your body's internal clock that regulates your sleep, hunger, hormone, and body temperature.
What is melatonin?
Melatonin is a natural hormone produced by the brain pineal gland that signals your body that it is time to sleep. Your brain sends this hormone as a response to darkness. The supplement version assists in helping people fall asleep.
How it's all connected
Exposure to blue light from screens disrupts and harms your circadian rhythm and melatonin by stimulating intrinsically photosensitive retinal ganglion cells (iRGCs) in the eyes causing melatonin to suppress and confuse the brain to stay awake.
usage effects
This would cause difficulty sleeping, poor sleep quality, increased alertness, and health risk over time. Additionally, disrupted sleep can diminish rapid eye movement (REM) sleep, which plays an important part in emotional processing. The result of this reduced segment of sleep causes psychological distress, reinforcing the compulsive need to use a phone as a comfort.
