US Neurologists Raise Concerns Over Cold Water Therapy
The rising popularity of cold water immersion, often promoted for recovery and health benefits, is facing criticism from neurologists and sports scientists. Cold plunges, often touted for improving immunity, reducing inflammation, and aiding muscle recovery, may not deliver consistent benefits, according to recent research.
Medical experts warn that cold immersion can disrupt the body’s natural inflammatory response, which is essential for muscle repair. A recent meta-analysis suggested that while cold therapy can reduce muscle soreness immediately after exercise, it does not significantly enhance long-term recovery or performance. In some cases, regular cold immersion has been linked to reduced muscle growth when combined with resistance training, raising concerns for athletes seeking strength gains.
Beyond potential interference with recovery, cold immersion poses risks through what’s known as the “cold shock response.” Neurologists caution that the sudden exposure to cold water can trigger spikes in heart rate and blood pressure, which may stress the cardiovascular system. For individuals with underlying health conditions, this could increase the risk of adverse events like heart attacks.
Though proponents argue that cold water plunges offer psychological benefits, such as increased alertness and mental resilience, experts urge moderation. “If it makes you feel good, go for it,” one researcher noted, “but using it routinely may hinder muscle adaptation in the long run”.
As cold therapy continues to gain traction through influencers and wellness trends, experts advise users to balance its use with caution and evidence-based recovery practices. While occasional immersion may provide subjective relief, consistent reliance could limit long-term benefits for athletes and fitness enthusiasts alike.
