The story behind silk

The domestication of silk originated in ancient China over 4,000 years ago and soon became a treasured and high-value commodity to trade. The luxurious fabric quickly spread across the world via the Silk Road and became a global symbol of wealth and status.
It was thought to have been introduced to the UK towards the late Middle Ages. As a luxury material that was difficult to produce, it was primarily reserved for royalty and wealthy elites who could afford the premium fabric for clothes, accessories and bed linen.

To this day, Mulberry silk, renowned for its softness, strength and lustrous sheen, continues to be a luxurious fabric choice, particularly for bed sheets, pillowcases and duvet covers.

How silk became a sleep essential

Silk is frequently used for clothing and accessories but the silky and supple fabric is also perfect for bed linen. When woven, the fabric is particularly suited to pillowcases due to its structure which feels soft and gentle against skin and hair so helps maintain its health. One of the many benefits of silk pillowcases is that they are smooth and breathable to sleep on.

The 9 benefits of sleeping on silk

1. Silk can help keep skin hydrated

Silk’s ultra-soft fibres may help retain moisture by being gentle against the skin, making silk pillowcases a great option for those with dry, dehydrated or sensitive skin. Silk is also less absorbent than a fabric like cotton, so one silk pillowcase benefit is that it may help to support skin moisture levels overnight, as it won’t draw out moisturising skincare products as readily as other fabrics.

2. Silk may reduce sleep creases

Some people believe that silk can minimise or prevent wrinkles. Though there is no significant evidence for this, silk’s soft texture and natural sheen can reduce the amount of friction on the skin, which could be a cause of morning creases from certain sleep positions. This may help to minimise premature skin creases over time.

3. Silk can be gentle on sensitive skin

Silk’s beautifully soft fabric may help to reduce irritation for sensitive skin. Another silk pillowcase benefit is that it’s naturally hypoallergenic and resistant to dust mites, which may be beneficial for those with eczema, allergies or other skin sensitivities. A pure-silk pillowcase also helps retains moisture while being gentle against delicate skin, which may help to support the skin’s health.

4. Silk can help smooth frizz

The naturally smooth and sumptuous texture of silk is softer than some other fabrics, making it gentler on your hair follicles as you change positions during sleep. Silk’s natural softness and surface sheen feel delicate against your hair, which may help to prevent additional frizz or breakage overnight.

5. Silk can help maintain hair hydration

Another of the renowned silk pillowcase benefits is that it could help to support hair hydration, making it a wonderful option for those with dry and damaged hair. Similar to its skincare benefits, silk’s low absorbency won’t draw moisture and natural oils away from hair as readily as a fabric like cotton will, which may help to prevent dryness.

6. Silk may maintain hairstyles for longer

Silk pillowcases are regularly used as a way of protecting hairstyles overnight. The smooth texture of silk can cradle your hair more gently as you sleep, which may reduce the need for frequent touch-ups.

7. Silk can help regulate temperature

Pillowcases crafted from pure silk are a popular fabric choice for temperature regulation. Cool to the touch even in summer, it’s great for sleeping in warmer climates and months. It’s also exceptionally breathable and can be naturally insulating when it gets chilly.
