It's hard to keep track of all the research that has determined kids' excessive use and exposure to screens is bad for their health.  A new study making headlines right now is that screen use and exposure can cause developmental delays in kids under the age of four.  A study published in June stated that excessive use of cell phones could shorten kids' lifespans.  One in April concluded it could lead to spinal problems and other risk factors (physical, physiological, psychological, and behavioral).  Of course, research has also determined that exposure to blue light from screens (and other sources) is biologically harmful.  Additionally, decades of research have also determined that exposure to electromagnetic fields (EMF) from cell phones and other wireless sources – including 5G –  is biologically harmful with children being especially vulnerable to it.  In fact, manufacturers are required to provide consumers with warnings about radiation exposure from cell phones and other wireless devices.

Weirdly enough, this new study with troubling results was conducted by requiring kids to wear smartwatches to monitor their behavior.  Of course, smartwatches (and other wearables) expose wearers to biologically harmful radiation too!

Inactivity and screen time among children linked to heart damage by young adulthood

by Study Finds

KUOPIO, Finland — Allowing children to consistently watch TV for extended periods can lead to heart-related issues years later, a new study warns. Researchers discovered that being inactive from childhood through young adulthood displays a link to heart damage, independent of factors like weight and blood pressure.

For every additional minute of inactivity between ages 11 and 24, there was a 0.004g/m (grams in relation to height) increase in the mass of the heart's left ventricle by the time these children reached 17 to 24 years of age.
