Dave Asprey, known as the 'Father of Biohacking', suggests a technique using red light on phones to improve sleep quality by not disrupting the circadian rhythm. Blue light from screens interferes with melatonin production, essential for sleep, making it harder to fall and stay asleep. Research shows that such exposure can diminish deep sleep and REM sleep, critical for cognitive function and mood regulation. With most Americans using screens before bed, Asprey's method becomes a practical solution to mitigate sleep disturbances caused by blue light exposure.
"This is what biohackers do so that their phones don't wake them up at night," Asprey told The Post.
"You should be able to wake up, check your alarm and go back to sleep, but if your iPhone is on this standard blinding mode, it doesn't work," Asprey said.
Studies show that nighttime exposure can reduce the time we spend in deep sleep and rapid eye movement (REM) sleep, which are both crucial for consolidating memories, regulating mood and supporting overall cognitive function.
The Sleep Foundation recommends powering down your electronic devices, like cellphones, at least 30 minutes before bed.
