Impact of Phones on Sleep Quality
Sleeping next to a smartphone may have controversial effects on brainwaves and sleep quality. Concerns stem from the electromagnetic fields emitted by phones, which could potentially affect sleep architecture, such as delaying REM sleep onset. More conclusive evidence suggests that blue light from smartphones suppresses melatonin production, disrupting circadian rhythms and leading to poorer sleep quality. Additionally, the psychological effects of constantly reaching for the phone contribute to anticipatory anxiety that negatively impacts sleep, indicating that the distractions posed by these devices outweigh any direct electromagnetic concerns.
