Five Minutes of Extreme Cold Might Help You Sleep Better, Study Finds
Introduction
Imagine standing in extreme cold, all for the promise of deeper sleep. A new study, published on November 21, 2024, suggests this icy approach might just work. Researchers from the University of Montreal and University of Poitiers explored how cryostimulation—exposure to freezing temperatures—can improve sleep quality.
Could five minutes of shivering lead to hours of rejuvenating rest? Let’s dive into the findings.
What is Cryostimulation?
Cryostimulation involves short, intense exposure to extreme cold, often in chambers cooled to temperatures as low as -130°F (-90°C). While commonly used by athletes for recovery, its effects on sleep are now under scrutiny.
This study tested the idea with 20 healthy adults, aged in their 20s, over five consecutive days. Each evening, participants stepped into a cryochamber for exactly five minutes at 6 p.m.. Their sleep patterns, heart rates, and brain activity were closely monitored using wearable devices and self-reported surveys.
Key Findings: The Science of Sleep and Cold
The results showed a promising trend—improved deep sleep, the most restorative stage of the sleep cycle:
- Slow-Wave Sleep Gains
- After five days, participants experienced an average of 7.3 extra minutes of deep sleep. Considering most adults get about two hours of deep sleep per night, this increase is significant.
- Perceived Sleep Quality
- Participants, especially women, reported feeling more rested.
- Delayed Benefits
- The improvements became evident only after several sessions, suggesting that consistency is key.
A Small Sample, Big Implications
Although the results are encouraging, the study had limitations. With only nine women and 11 men participating, the sample size was small. The researchers emphasized the need for larger studies to validate these findings.
Nonetheless, the results point to a potential application of cryostimulation for those with chronic sleep issues. According to Olivier Dupuy, an associate professor at the University of Montreal, “Cryostimulation could be especially beneficial for people with sleep problems.”

More Than Just Sleep: The Other Benefits of Cryostimulation
Cryostimulation isn’t just for sleep. The therapy is part of a larger research initiative exploring its potential health benefits, such as:
- Pain and Inflammation Relief
Studies suggest that extreme cold can reduce inflammation, making it popular among athletes. - Enhanced Recovery
Elite athletes have used cryotherapy to recover faster, including during the recent 2024 Summer Olympics in Paris.
Should You Try Cryotherapy?
Before you book a cryotherapy session, consider these points:
- Incremental Gains: The study showed modest improvements, not life-changing ones.
- Safety First: Always consult with a healthcare professional before trying extreme therapies.
- More Research Needed: The findings are preliminary, and further studies will determine how effective cryostimulation is for broader populations.
The Future of Cryostimulation
As research continues, cryostimulation might soon find its place in clinics, particularly for treating sleep disorders. Dupuy and his team plan to publish additional studies, which could solidify its benefits.
With its potential to help both sleep and physical recovery, this therapy could redefine how we approach rest and wellness.
Conclusion
While you may not be ready to step into a cryochamber just yet, the idea of chilling out for better sleep is intriguing. As science delves deeper, we might soon have a cold, new remedy for restless nights.
Would you take the plunge into freezing temperatures for a shot at a better night’s rest?
