Subject: Can’t sleep? How technology affects your sleep patterns and what you can do.
“That’s because of the short-wavelength, artificial blue light that digital devices emit, which delays your body’s internal clock and circadian rhythm, and suppress the release of melatonin, the sleep-inducing hormone, according to the National Sleep Foundation.”
“The more electronic devices that a person uses in the evening, the harder it is to fall asleep or stay asleep,” according to the foundation. “Besides increasing your alertness at a time when you should be getting sleepy, which in turn delays your bedtime, using these devices before turning in delays the onset of REM sleep, reduces the total amount of REM sleep, and compromises alertness the next morning. Over time, these effects can add up to a significant, chronic deficiency in sleep.” – https://www.businessinsider.com/technology-negative-bad-effects-society-2019-8#insomnia-can-be-another-side-effect-of-digital-devices-3
“We insist on using LED-based devices close to our eyes right up to bedtime even though it negatively impacts sleep and our brain’s nightly needs for synaptic rejuvenation harming our ability to retain information.” – Larry Rosen – https://www.pewresearch.org/internet/2018/04/17/concerns-about-the-future-of-peoples-well-being/
“Then there’s “social jetlag.” The idea is that people are so tired on Mondays because they follow different sleep patterns on workdays and the weekend. On the weekend, they tend to stay out later for socializing. On Monday, they have to get up earlier for work. This creates an effect similar to jetlag — since the body is forced to adjust to different sleep times throughout the week.” – https://www.vox.com/2015/2/10/8008005/sleep-facts
“The brain has a very habitual, routine structure. It likes to have its solid seven hours every night, seven nights a week.” – https://www.vox.com/2015/2/10/8008005/sleep-facts
“people who use iPads — or any light-emitting device — before bed are less sleepy at night, take longer to fall asleep, feel less alert in the morning, and spend less time in the REM stage. This is possibly because the blue light is suppressing production of melatonin, the hormone that makes people feel sleep.” – https://www.vox.com/2015/2/10/8008005/sleep-facts
