Sleep Cooler and Deeper: Discover the Benefits of Kailu Silk

Why does temperature regulation matter so much for women’s sleep—and what makes Kailu Mulberry Silk a natural solution?

When we set out to find the perfect partner for sleepwear and bedding that could truly support women at every stage of life, Kailu stood out for one reason above all: temperature regulation.

Fluctuating body temperatures, night sweats, and hot flashes are a major disruptor for so many women, particularly during perimenopause and menopause. We wanted a material that could adapt as the body changes—keeping you cool when you’re overheated, warm when you’re chilled, and dry through it all.
Kailu’s Grade 6A Mulberry Silk delivers on all fronts.

Here’s why we chose them—and why their silk makes such a difference:

How Kailu Mulberry Silk Helps Regulate Temperature

1. Breathable, Porous Structure
Mulberry silk is composed of fibroin, a natural protein with a very fine, porous structure. These tiny air pockets allow silk to breathe exceptionally well, trapping just enough air to insulate in cooler conditions and ventilate when it’s warm. This dynamic breathability helps counter the sudden heat spikes and chills that can accompany hot flashes.

2. Powerful Moisture Wicking
Silk can absorb up to 30% of its weight in moisture without ever feeling damp. When a hot flash strikes and sweating follows, Kailu silk draws moisture away from the body and releases it into the air—keeping your skin feeling cooler, drier, and more comfortable throughout the night.

3. Natural Thermal Control
Unlike synthetic fibers that trap heat, silk has low thermal conductivity, meaning it slows the transfer of heat. This creates a buffering effect:

• In hot conditions (like post-hot flash), it cools and releases excess heat.

• In cooler moments, it retains a comfortable warmth without overheating.

This adaptability is crucial for women whose bodies are constantly recalibrating internal temperatures during hormonal changes.

4. Clean, Hypoallergenic Freshness
Kailu’s mulberry silk is naturally resistant to mold, dust mites, and bacteria—common allergens that can clog fabrics and contribute to trapped heat. A cleaner fabric means better airflow, maintaining that crucial breathability night after night.

Why Temperature Regulation Matters for Menopause and Perimenopause

During perimenopause and menopause, fluctuating estrogen levels affect how the body regulates heat.

• Hot flashes can cause sudden, intense bursts of heat, flushing, and sweating.

• Night sweats can soak through bedding and disturb sleep cycles.

• Temperature sensitivity makes it harder to find and maintain a comfortable sleeping environment.

Without the right support, these symptoms can lead to disrupted sleep, increased fatigue, and a negative spiral that impacts overall health.

Kailu Mulberry Silk responds naturally and intelligently to these shifts—offering relief without complicated technology or chemical treatments. It’s a simple, beautiful way to help women find more restorative, uninterrupted sleep during one of the most transformational periods of life.
