From the Guidelines
Cold plunges are not recommended to prevent Deep Vein Thrombosis (DVT). There is no scientific evidence supporting cold water immersion as an effective preventive measure for DVT. In fact, exposure to cold can potentially cause vasoconstriction (narrowing of blood vessels), which might theoretically increase rather than decrease clotting risk in some individuals. For DVT prevention, established methods include:
- Regular movement (especially during long periods of sitting)
- Staying hydrated
- Wearingling compression stockings when appropriate, as shown in a systematic review of 11 randomized trials that included 2,906 individuals, which revealed the benefits of compression stockings (15–30 mmHg) on reducing the incidence of asymptomatic DVT 1
- Taking prescribed anticoagulant medications if you're at high risk, such as low-molecular-weight heparin, which was shown to be effective in the LONFLIT-3 study 1. DVT prevention works by either keeping blood flowing normally through the veins (through movement and hydration) or by directly reducing blood's ability to clot excessively (through medication). If you're concerned about DVT risk, particularly before long flights or periods of immobility, consult with a healthcare provider for personalized prevention strategies rather than attempting cold plunges.
From the Research
Cold Plunges for DVT Prevention
- There is no direct evidence in the provided studies to support the use of cold plunges for Deep Vein Thrombosis (DVT) prevention 2, 3, 4, 5, 6.
- The studies focus on the use of graduated compression stockings, anticoagulation, and other methods for DVT prevention, but do not mention cold plunges as a preventive measure.
- DVT prevention methods mentioned in the studies include:
- The effectiveness of these methods in preventing DVT is supported by the studies, but the use of cold plunges is not addressed 2, 3, 4, 5, 6.
