What Researchers Did
Researchers investigated whether a predive far infrared-ray dry sauna session influenced venous gas bubble formation and hemodynamic parameters after a simulated dive.
What They Found
A single predive sauna session significantly reduced venous gas bubble formation by 27.2% at rest and 35.4% after flexions following a simulated dive. The sauna also led to extracellular dehydration, a 2.7% decrease in plasma volume, a 0.6% bodyweight loss, increased flow-mediated dilation, and a rise in plasma HSP70.
What This Means for Canadian Patients
For Canadian divers, incorporating a predive sauna session might offer a practical way to reduce the risk of decompression sickness by decreasing bubble formation. This simple intervention could potentially enhance dive safety, especially for those engaging in activities with decompression risks.
Canadian Relevance
This study has no direct Canadian connection as it was not conducted in Canada nor involved Canadian researchers or participants.
Study Limitations
The study involved a small sample size of 16 divers and used a simulated dive environment, which may not fully reflect real-world diving conditions.
