| Risk Factor | Reason | |-------------|--------| | | Higher inert gas loading | | Long bottom times (>60 min) | More time for micronuclei formation | | Repetitive dives | Residual gas loads | | Cold water dives | Peripheral vasoconstriction traps gas | | Fast ascent rates (even within deco) | Supersaturation stress | | Dehydration | Slower gas washout | | Post-dive hot shower | Vasodilation + bubble mobilization | | History of mild DCS | Possible subclinical bubble predisposition | | High body fat % | Nitrogen solubility in adipose tissue | 6. Differential Diagnosis (What Else It Could Be) Before labeling an itch as “divelocked,” rule out these mimics: Cool a glove if needed
