Hand-held tech dangers are worse than we thought

[...]the term "washerwoman's strain" came into the lexicon After the advent of crank wringers and automatic washing machines, we did not hear too much about DeQuervain's until about 15 years or so ago when the first smartphones were released. Sara Thomée, Annika Härenstam and Mats Hagberg ("Mobile Phone Use and Stress, Sleep Disturbances, and Symptoms of Depression Among Young Adults - A Prospective Cohort Study,", BMC Public Health, 2011) found that "more usage equates to more mental stress." According to the U.S. National Safety Council (NSC), the use of mobile phones is implicated in 1.5 million vehicle accidents each year; 8.5% of all fatal motor vehicle crashes involve the technology and as many as 6,000 people die per year in these crashes. (Another poll taken during the AEC found that 44% of respondents limited screen time for their young children; 2% did not and the remainder answered N/A.) Jawad Fares, Mohamad Y. Fares and Youssef Fares reported in "Musculoskeletal Neck Pain in Children and Adolescents: Risk Factors and Complications" (National Center for Biotechnology Information, 2017) that adolescent spinal deformities from the use of hand-held technology are becoming more prevalent.
