Cool by Nature: Why Silk Is the Best Fabric for Hot Sleepers

If you constantly flip your pillow to the “cool side” or wake up sweaty no matter the season, your bedding may be to blame. Most people don’t realize that the material you sleep on plays a major role in how well you regulate body temperature throughout the night.

That’s why more and more hot sleepers—and even dermatologists—are turning to Mulberry silk pillowcases. Naturally breathable and thermo-regulating, silk is one of the best fabrics for cooling comfort. And at MYK Silk, we’re here to help you sleep cooler, deeper, and better.

🌡️ 1. Silk Is Naturally Thermoregulating

Unlike synthetic fabrics or heavy cotton, silk reacts to your body temperature in real time. It helps wick excess heat and moisture away from the skin while keeping you comfortably insulated—without trapping body heat.

Silk’s protein fibers allow for:

• Excellent breathability

• Rapid evaporation of sweat

• Comfort across seasons—cool in summer, cozy in winter

In fact, silk has been used for centuries in both warm and cold climates for its climate-adaptive properties.

💤 2. The Best Fabric for Hot Sleepers & Night Sweats

If you’re a hot sleeper or experience hormonal fluctuations, menopause, or anxiety-induced sweating, traditional bedding can worsen discomfort. Fabrics like polyester and satin (which is often polyester-based) trap heat and moisture, creating a sticky, suffocating sleep environment.

Silk does the opposite:

• Keeps your pillow cool to the touch

• Prevents the buildup of dampness or bacteria

• Allows skin to breathe and regulate itself naturally

That’s why dermatologists and sleep specialists often recommend silk for people who struggle with overheating or skin irritation at night.

🌬️ 3. Cooler Fabric = Better Sleep Quality

According to the National Sleep Foundation, a cooler sleeping environment—ideally between 60–67°F—is one of the most important factors in falling and staying asleep. Your bedding can either help or hinder that process.

Silk supports:

• Faster sleep onset

• Fewer night-time awakenings

• Deeper, more restorative REM sleep

MYK Silk pillowcases are ultra-lightweight and breathable, helping regulate your body temperature so your sleep cycle isn’t disrupted by overheating.

🌱 4. Unlike Satin, Silk is a Natural, Breathable Fiber

Many people confuse “satin” with silk due to its sheen, but satin is a weave, not a material. Most satin pillowcases are made from synthetic polyester, which traps heat, doesn’t breathe, and contributes to microplastic pollution.

Silk, by contrast, is:

• A natural protein fiber

• Free of plastics and synthetics

• Moisture-wicking without absorbing your skincare

That means better skin, better sleep, and a lighter environmental footprint—all while staying cool and dry throughout the night.
