Many popular claims about trauma therapy based on The Body Keeps the Score rely on limited or promotional sources rather than solid scientific evidence. This leads to confusion between compelling body-memory ideas and the actual, often inconclusive, research on trauma treatment effectiveness. Recognizing these gaps helps avoid uncritical acceptance and encourages demand for rigorous data that can truly improve trauma therapy outcomes.

Hour caps are the popular fix, yet much of the evidence points elsewhere. These views argue over content quality, context, and co-viewing versus raw hours, with some critiquing the research itself and others insisting sleep and community matter more than screens do. Weigh the panic against the evidence and decide what screen time means for your family.

Longevity medicine offers varied guidelines on exercise intensity, supplement timing, medical screening, and cold exposure.
