Silk textiles have long been recognized for their ability to help regulate body temperature in children and adults alike. Most commonly found in undergarments, long johns, and bed sheets today, silk has been helping people stay warm and keep cool for thousands of years!
The secret to silk's success boils down to very fine construction. Derived from the cocoons of silkworms, silk fibers are mostly constructed of natural proteins that have been spun together. The resulting long, double stranded fibers are much more similar to human hair than common plant-based textiles like cotton and linen, which helps explain why silk fabric is so well-suited to regulating body temperature. When you are too warm or too cool, silk acts as a permeable barrier between your skin and the surrounding air. It absorbs and dissipates excess heat, then reflects enough body heat back onto the wearer to keep temperature consistent.
