Screens and Sleep
Technology and Our Healthy Sleep
Research shows that light from screens and radiation from wireless can impact our sleep. The quality of our sleep profoundly impacts learning and memory and is essential for retaining new information. A sleep-deprived child cannot focus their attention as well as a child who had a good night’s sleep. Early research showed that teenagers who use their phones more had more trouble falling asleep and staying asleep and were more tired and stressed than those who sparingly used their phones. New research confirms these associations and strongly suggests that simple basic changes to our tech use and nighttime routines can result in a better night’s sleep.
Furthermore, research shows that sleep is a time when the brain cleans out toxins accumulated during the daytime. Ensuring a healthy sleep is one of the most powerful steps we can take to prevent illness and protect our family’s health and wellbeing.
Wireless radiation impacts sleep in several ways.
Research has shown that exposure to wireless radiation results in delayed entrance into deep non-REM sleep and decreases time spent in certain sleep stages.
- The blue light from screens has been shown to disrupt sleep cycles. The American Medical Association issued a policy to develop and implement healthier technologies recognizing “that exposure to excessive light at night, including extended use of various electronic media, can disrupt sleep or exacerbate sleep disorders, especially in children and adolescents.”
- Research on wireless radiation has shown that it inhibits the production of a hormone called melatonin (see the scientific references at the bottom of this webpage). Melatonin is secreted in the pineal gland in the brain. One of its primary functions is to regulate our sleep cycle. When inadequate amounts of melatonin are produced, our sleep cycle is compromised.
