Exposure to cold temperatures raises blood pressure.

INSUFFICIENT LEANING
Recorded sources
7 sources for · 0 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that exposure to cold temperatures raises blood pressure?

Unclear. Several peer-reviewed studies and reference sources indicate that cold exposure is associated with higher blood pressure, including a small lab study reporting large systolic and diastolic increases during cold water immersion and reviews of winter hypertension. However, the evidence is partial: it covers specific populations, settings, or seasonal patterns rather than establishing the general claim outright.
