Updated Nov 5, 2026 ## Key points - No pathognomonic sign: the diagnosis rests on circumstances, risk factors and exclusion. - Wischnewski spots: pinpoint brown erosions of the gastric mucosa; supportive, but their sensitivity and specificity are poorly defined. - Paradoxical undressing: the victim takes off clothing in the final phase; it can mimic an assault. - Pink livor and red-violet patches over the joints; pink livor also appears in refrigerated bodies and carbon monoxide poisoning. - A cold body cannot be used to estimate time of death from cooling. ## What it is Death from hypothermia occurs when core temperature falls so far that the heart fails. It has no pathognomonic sign: it is diagnosed from the circumstances (cold, wind, wet, mountains or páramo), the risk factors (alcohol, old age, homelessness, illness) and the exclusion of other causes. Supporting findings are Wischnewski spots (small brown erosions in the stomach lining), red-violet patches over the knees, elbows and hips, and pink livor. Some victims undress in the final phase (paradoxical undressing) or hide in corners, which can mimic sexual assault or robbery. ## How to tell it apart - Versus sexual assault or robbery: removed clothing and a disordered scene may be due to paradoxical undressing. - Versus carbon monoxide poisoning: also gives reddish livor; carboxyhaemoglobin settles it. - Versus natural or toxic death in a cold place: cold may be the cause or only a contributor. - Deep hypothermia can mimic death: do not declare death without proper criteria. ## How to recognise it - Pink or light-red livor. - Red-violet patches over the knees, elbows, hips and hands. - Wischnewski spots: many small brown or blackish erosions in the stomach lining. - Clothing removed and scattered, body hidden in a corner or under furniture. - Leg abrasions and a disordered scene from the confusion of the final phase. ## How it forms - Cold leads to confusion, bradycardia, arrhythmias and finally cardiac arrest. - Peripheral vasoconstriction gives way in the final phase and causes a sensation of warmth that may explain paradoxical undressing. - Cold keeps oxyhaemoglobin in the skin and gives livor its pink colour. ## Next step: what to do and document - Before certifying death in a person found in the cold, check the criteria of death: deep hypothermia can mimic it. - Document the ambient temperature, weather, clothing (worn and removed) and the exact place of the body. - Request a full medico-legal autopsy and toxicology (alcohol and drugs) with a chain of custody. - Describe separately in the report the findings that support hypothermia and those that suggest another cause. - In older or dependent people found in the cold, consider abandonment or neglect and report if appropriate. ## Common mistakes - Using body temperature to fix the time of death in a cold environment. - Reading paradoxical undressing as proof of sexual assault. - Diagnosing hypothermia without ruling out intoxication and natural disease. - Declaring a person in deep hypothermia dead without proper criteria. ## Test yourself Think of the answer, then tap the question to see it. ## What are Wischnewski spots? Small brown or blackish erosions in the stomach lining, found in some hypothermia deaths; they support the diagnosis but do not prove it. ## What is paradoxical undressing? Taking off clothing in the final phase of hypothermia; it can wrongly suggest sexual assault or robbery. ## Can body temperature be used to estimate time of death in a death from cold? No. The body was already cold before death, so cooling does not allow the postmortem interval to be calculated. ## Which other cause of reddish livor must be ruled out in a death from cold? Carbon monoxide poisoning, confirmed by measuring carboxyhaemoglobin.
