New Research Challenges the Benefits of Ice Baths and Cold Plunges
From Joe Rogan to Jennifer Aniston, many celebrities and influencers have praised the benefits of ice baths and cold plunges. These popular wellness practices are believed to reduce stress, ease exercise-induced muscle damage, and boost immune system function.
Cold Water Immersions Become Questioned
However, a recent study published in the PLOS One journal has cast doubt on these purported benefits. Conducted by researchers at the University of South Australia, the analysis reviewed data from 11 studies involving 3,177 participants who engaged in cold water immersions, typically characterized by being submerged in water at 15 degrees Celsius or lower for at least 30 seconds.
Unexpected Findings on Inflammation
One of the most surprising revelations from the study is the apparent contradiction regarding inflammation reduction. Critics of cold water immersions have long argued that the practice can increase inflammation levels rather than decrease them. The study supports this notion by showing a significant spike in inflammation both immediately and one hour after immersion.
“A significant increase in inflammation immediately and one hour” after the practice was observed, according to the findings. Researchers explain this as an acute inflammatory response—basically, the body’s reaction to cold as a stressor, which can actually aid in recovery over the long term by helping the body adapt.
Co-author Ben Singh acknowledged the apparent contradiction in a press release, explaining that the increase in inflammation is a normal, adaptive response similar to the muscle damage incurred during exercise, which eventually leads to strength and recovery.
Health Risks for Some Users
While the acute inflammatory response may be beneficial for certain groups, particularly elite athletes, it poses potential risks for individuals with pre-existing health conditions. Singh emphasized the importance of caution for participation in cold water rituals, given that the initial inflammation could have adverse health impacts.
Reduction in Stress and Increased Wellness
The study did uncover some advantages associated with cold water immersions. Notably, it found a significant reduction in stress levels 12 hours after the immersion process. However, this stress-reducing effect was not evident immediately after, or one, 24, or 48 hours post-immersion.
Another benefit highlighted in the study was a 29 percent reduction in sickness absence among participants who took cold showers regularly. This suggests that while the practice might not alleviate all concerns, it can play a role in promoting general wellness by boosting the body’s resilience against illnesses.
Further Research Needed
Despite these insights, the researchers emphasized that more high-quality research is required to fully understand the effects of cold water immersions. Co-author Cain mentioned the need for long-term studies involving diverse populations to identify who benefits most from these practices and to determine the optimal method of using them.
“Whether you are an elite athlete looking for an edge or a health enthusiast seeking wellness improvement, it’s crucial to be aware of what your body goes through,” Cain stated. “Currently, we don’t have a comprehensive understanding of cold water’s lasting effects and best applications. Ongoing research could provide clearer guidance on these matters.”
