5-Minute Daily Exposure to Extreme Conditions Enhances Sleep and Mood

A study by the University of Montreal and the University of Poitiers suggests that five minutes of cryotherapy at -130°F for five consecutive days can enhance sleep quality and mood, particularly benefiting women. The research found an increase in slow-wave sleep by 7.3 minutes and improved psychological wellness. While the study focused on healthy young adults, it indicates potential benefits for those with sleep issues and athletes, with additional advantages like reduced anxiety and inflammation.
