The science BaroSit follows

A single "standard posture" that fits everyone has never been scientifically validated. A literature review concludes that the "standard posture" is, in effect, closer to a myth.

Synthesizing 41 systematic reviews, there is no causal consensus that any particular posture or physical exposure "causes" low back pain; the associations are weak and inconsistent.

The link between forward head posture and neck pain is weak in adults and not statistically significant in adolescents — and since all the evidence is cross-sectional, it cannot establish causation.

The risk of prolonged sitting depends heavily on how active you are. 60–75 minutes of moderate-intensity physical activity a day essentially offset the mortality risk linked to high sitting time.

About 5 minutes of light movement (walking) every 20–30 minutes was the break cadence with the strongest evidence for blood-sugar and fatigue measures.

Reminders such as on-screen prompts are reported to cut objectively measured sitting time by roughly 12 minutes a day (meta-analysis of 18 randomized controlled trials).
