Two Natural Fibres, Very Different Sleep Experiences
Cotton and silk are both natural, breathable fabrics - but that's roughly where the similarities end. When it comes to sleep quality, skin health, and long-term wellbeing, they perform quite differently. Here's how they compare.
Temperature Regulation
Silk: Naturally thermoregulating - it adapts to your body temperature, keeping you cool in summer and warm in cooler months. Ideal for anyone who wakes up overheated or chilled.
Cotton: Breathable but tends to trap heat and moisture over the course of the night, especially in warmer climates. Egyptian cotton is better than standard cotton but still can't match silk's adaptive properties.
Friction and Skin Impact
Silk: Its ultra-smooth surface creates minimal friction against skin and hair - reducing sleep creases, breakage, and irritation. Our Organic Silk Pillowcase in Natural White and Olive Green are specifically designed with this in mind.
Cotton: The woven texture creates more friction, which can tug at facial skin overnight and contribute to hair frizz and breakage over time.
Moisture Absorption
Silk: Less absorbent than cotton, meaning your overnight serums and moisturisers stay on your skin rather than being wicked into your pillowcase.
Cotton: Highly absorbent - great for towels, but less ideal when you want your skincare to actually work overnight.
Allergens and Sensitivities
Silk: Naturally hypoallergenic and resistant to dust mites and mould. A better choice for those with allergies, asthma, or sensitive skin.
Cotton: More susceptible to dust mite accumulation and can harbour allergens if not washed frequently.
Light Blocking
For total sleep support, fabric alone isn't enough. Our Silk Sleep Eye Mask with Light Blocking pairs the skin benefits of silk with complete darkness - something no cotton pillowcase can offer.
The Verdict
Cotton is a reliable everyday fabric. But for sleep - where your skin, hair, and nervous system are all in recovery mode — silk wins on almost every measure. Explore our range of Organic Silk Sleep Bundles and experience the difference for yourself.
