Ice Bath / Cold PlungepracticeUnclear
A case series described 9 women who developed transient global amnesia during or immediately after cold-water sea swimming; all recovered within 24 hours, and no further episodes were reported during follow-up. The report describes these events but does not establish how often they occur.

How to read the evidence
Evidence tier — overall strength of the evidence for the whole compound
- StrongWell established — backed by strong, consistent human research.
- ModerateSome genuine support, but mostly from small or lower-quality studies. Promising, not proven.
- PreliminaryEarly-stage evidence — a promising hypothesis, not an established effect yet.
- LimitedVery limited evidence — treat this as a hypothesis, not proof.
- InsufficientNot enough good evidence to draw conclusions yet.
Certainty — how sure we can be that the effect is real
- Very highVery sure — strong, consistent evidence
- HighFairly sure — consistent evidence from good studies
- MediumModerately sure — new studies could change this
- LowNot sure — little or mixed evidence
- Very lowVery unsure — almost no usable evidence
Source — where the data comes from
- Meta-analysisPooled analysis of many trials — the strongest evidence
- RCTRandomized controlled trial — a strong human study design
- ClinicalA human clinical study
- Reference knowledgeFrom general health-science or pharmacology references, not a study of this exact claim
- Animal researchStudied in animals, not humans
- Community reportsAggregated user reports — anecdotal signal, not evidence
- TheoreticalMechanism-based reasoning, not yet tested
Study grade — quality of each underlying study (A best, D weakest)
- AHigh-quality — strong, consistent human trials
- BGood — solid evidence with some limitations
- CModerate — limited, small, or mixed-quality studies
- DWeak — preliminary, indirect, or animal-only
Confidence — how strongly the sources back a finding
A 0–100 score from study quality and agreement
Most supplement evidence is graded C–D. Read it as preliminary signal, not proof.
Full write-up
What is it
Transient Global Amnesia is categorized as a neurological health condition. This reference provides basic context about the condition and its classification. It is educational information, not a diagnosis or treatment recommendation; questions about symptoms, diagnosis, or care should be discussed with a qualified clinician.
Evidence-backed options
No evidence-backed options are listed for Transient Global Amnesia. As a result, there is no supported information to summarize about what was taken, how long it was used, how quickly effects appeared, or whether findings were consistent or limited. Anyone seeking information about this condition should discuss it with a qualified clinician.
What to avoid
Ice Bath / Cold Plunge is flagged because transient global amnesia has been reported during or immediately after cold-water sea swimming. This represents a temporal association rather than proof that cold exposure causes the condition, and the available evidence is limited to case reports rather than controlled research.
In the reported cases, the memory disturbance resolved within 24 hours, with no further episodes described during follow-up. Because the condition involves sudden, temporary changes in memory, cold-water exposure may be an important consideration for people with a history of transient global amnesia. Anyone with this condition should discuss the suitability of Ice Bath / Cold Plunge with a clinician.
