Restful Sleep
37.5 active particles absorb the infrared (IR) energy that your body naturally emits, energizing the particles to speed evaporation and aid temperature regulation. Bedding with 37.5 Technology keeps you in your comfort zone more than two times longer.

37.5 Temperature Regulation
The Proof Is in the Testing
Both lab testing and consumer product testing has shown the unmistakable impact that 37.5 Technology has on helping to optimize your body’s ability to regulate temperature and humidity.
- Bedding products with 37.5 Technology show a relative temperature balancing effect between 5°F to 19°F, compared to standard bedding products without 37.5 Technology that have similar specifications and constructions.
- A temperature regulating bedding system containing 37.5 Technology keeps you in the comfort zone more than two times longer than traditional bedding without 37.5 Technology.
- In a study done at the Olympic Training Center, 80% of participants preferred a bedding system containing 37.5 Technology over one without our thermoregulation technology.
FAQs
Bedding
Temperature regulating bedding is designed to actively manage your body’s microclimate during sleep, helping to ensure optimal comfort and restfulness. Traditional bedding materials can trap heat and moisture, leading to discomfort and disrupted sleep. However, the temperature regulating bedding with 37.5 Technology features active particles derived from natural sources to capture and release moisture vapor, helping to maintain an ideal relative humidity in your sleep environment. Whether you’re a hot or cold sleeper, this dynamic temperature regulation can help you achieve a more comfortable and rejuvenating sleep experience.
Absolutely. Temperature regulating bedding powered by 37.5 Technology is proven to enhance sleep comfort. Testing at Inside Climate demonstrated a relative temperature balancing effect of 5 – 19° F (or 3 – 12° C) when the temperature regulating bedding products with 37.5 Technology were compared against standard bedding products. This means that you spend more than two times longer in your ideal comfort zone when you sleep in a bedding system featuring 37.5 Technology.
The best bedding to regulate temperature typically includes materials that actively manage heat and moisture, promoting a comfortable sleep environment. Breathable fabrics like cotton or linen can allow for better airflow and moisture wicking, helping to prevent overheating. However, when 37.5 Technology’s natural active particles are embedded in these fabrics and other textile materials, water vapor is removed before it turns to sweat, offering a far more dynamic management of the microclimate between the fabric and your skin.
During winter, the 37.5 natural active particles used in temperature regulating sheets absorb your body’s infrared energy, powering the particles to remove moisture, helping to keep you warm and cozy throughout the night. In the summer months, the same technology works to cool you down by speeding evaporation to remove excess heat and moisture, allowing for a refreshing sleep experience. This unique ability to regulate temperature helps ensure that sheets and other bedding with 37.5 Technology provide the perfect balance of warmth in winter and coolness in summer, for a restful night’s sleep year-round.
37.5 Technology traps odors and releases them when laundered or cleaned. Users have found fabrics made with 37.5 Technology stay fresher, longer.
No. 37.5 Technology is made from naturally occurring volcanic minerals. It is not a chemical finish and does not contain harmful chemicals.
No. 37.5 active particles are permanently embedded at the fiber level, work for the life of the product, and will not wash out during laundering.
