Brief Cold Exposure Linked to Improved Sleep Quality

A study by researchers from the University of Montreal and the University of Poitiers suggests that spending five minutes daily in extremely cold temperatures can improve sleep quality, particularly deep sleep. The study involved 20 young adults who underwent cryostimulation in a -130°F chamber for five days, showing increased deep sleep duration and improved sleep quality, especially among women. While the findings are promising, they are based on a small sample size, and further research is needed to confirm the benefits for those with sleep issues. The study is part of broader research into the health benefits of cryostimulation.
