A randomized trial examining the effects of cold exposure and controlled breathing techniques has found that practicing the two together can significantly reduce perceived stress, offering insight into non-pharmaceutical approaches to winter wellness.

A growing body of research suggests that intentional exposure to cold environments, when paired with structured breathing techniques, may strengthen stress resilience and support overall health during the winter months, according to findings from a randomized trial conducted by researchers Cristopher Siegfried Kopplin and Louisa Rosenthal.
The study found that participants who combined a pranayama-inspired breathing technique with brief cold exposure over a two-week period experienced a clinically meaningful reduction in perceived stress of more than 20 percent. By contrast, participants who practiced only the breathing exercises or only cold exposure did not show statistically significant stress reductions compared with a control group.
Researchers reported that the combined protocol produced a medium-to-large positive effect on lowering perceived stress, highlighting what they described as a synergistic interaction between the two practices. The findings suggest that neither intervention alone was sufficient to produce substantial benefits, but together they activated adaptive stress responses linked to improved regulation of the nervous system.
The breathing technique used in the trial involved repeated cycles of deep inhalation followed by breath retention, while cold exposure was introduced through brief cold showers. According to the study, the breathing exercises appeared to induce a focused and regulated mental state, making participants more tolerant of the cold exposure and enhancing its overall physiological impact.
The researchers connected these findings to the concept of hormesis, a biological principle in which moderate, short-term stressors stimulate adaptive responses that strengthen the body. Cold exposure was shown to briefly activate stress hormones and the sympathetic nervous system, while controlled breathing influenced autonomic nervous system balance. When combined, the practices appeared to train participants to better tolerate discomfort and reduce their overall perception of stress.
The study arrives amid rising global rates of perceived stress, which researchers note is associated with increased risks of anxiety, depression, and inflammation-related illnesses. The trial also observed that perceived stress often contributes to unhealthy coping behaviors, including poor diet and substance use, reinforcing cycles of physical and mental strain.
In addition to modern clinical findings, the study aligns with historical practices in cold-climate regions, particularly in Russia and the former Soviet Union, where deliberate cold exposure was commonly incorporated into child-rearing and early education. From the mid-20th century onward, infants and young children were frequently placed outdoors to nap in winter temperatures, encouraged to play outside in cold conditions, and exposed to cold water following sauna use. These practices, often referred to as “hardening,” were intended to strengthen respiratory systems and improve resistance to illness.
Researchers noted that while such practices have become less common in recent decades, they reflect a long-standing belief that controlled exposure to cold environments can support immune function and physical resilience when applied carefully and consistently.
The trial’s findings suggest that structured breathing combined with deliberate cold exposure may offer a low-cost, accessible approach to stress management during winter months. The researchers emphasized that the benefits were achieved without medication and required no specialized equipment, relying instead on consistent practice and controlled exposure.
According to the study, the results underscore the importance of how stressors are applied, suggesting that moderate, intentional challenges may strengthen the body’s adaptive capacity rather than undermine it.
