Choking during sexual activity should be avoided as it is associated with markers of brain injury.

This advice is based on an observational study of 32 women published in the 'Journal of Forensic and Legal Medicine'. The study observed an elevation in the S100B biomarker among participants who reported frequent choking practices; this is a biological indicator used clinically to screen for suspected brain trauma (e.g., in cases of head injury). However, although the correlation is statistically significant within this small sample, this is an observational study: it shows an association but does not formally prove that choking is the direct cause of injury in all individuals, nor does it establish the extent of long-term damage. The S100B marker is sensitive but lacks specificity, as it can be elevated following intense physical exertion or other physiological stressors. Extrapolation to the general population is limited by the study's small sample size. The claim is therefore biologically plausible and cautious, but requires further research to confirm precise causality.
