Most people spend years optimising their sleep. Blackout curtains, white noise machines, magnesium supplements. And yet almost nobody questions what they are actually sleeping on. The fabric touching your face for eight hours a night matters more than most people realise.
Here is the science behind why silk is different.
Temperature Regulation
Silk is a naturally temperature-regulating fibre. Unlike cotton, which absorbs moisture and can leave you feeling damp and cold, silk adapts to your body temperature, keeping you cool in summer and warm in winter. This happens because silk is a protein fibre with a triangular cross-section that reflects light and regulates airflow at a microscopic level.
For people who run hot at night, or who wake up in the early hours feeling too warm or too cold, this alone is a significant upgrade.
Friction and Skin
Cotton has a relatively rough surface at the microscopic level. Over the course of a night, this creates friction against your skin, contributing to sleep creases, irritation, and over time, accelerated skin ageing around the face and décolletage.
Silk's surface is smooth and low-friction. Your skin glides across it rather than dragging. This is why dermatologists frequently recommend silk pillowcases for people with sensitive skin, acne-prone skin, or those undergoing skincare treatments they do not want disrupted overnight.
Hair Breakage
The same friction that affects skin affects hair. Cotton pillowcases cause hair to snag and tangle during sleep, leading to breakage, frizz, and split ends, particularly for people with curly, textured, or chemically treated hair.
Silk allows hair to move freely. You wake up with less breakage and less frizz. It is a small change with a surprisingly visible result.
Hypoallergenic Properties
Silk is naturally resistant to dust mites, mould, and other common allergens. For people with allergies or asthma, this makes it a meaningfully better choice than conventional bedding materials.
The Grade Matters
Not all silk is equal. The quality of mulberry silk is graded from A to 6A, with 6A being the highest classification available, the finest, most consistent, and most durable grade on the market. At Blume, we use only 6A grade mulberry silk, sourced from Suzhou, China, where silk cultivation has been refined over 2,000 years.
The difference between 6A and lower grades is immediately apparent in the hand feel. Smoother, heavier, more lustrous. It also holds its quality wash after wash.
The Simple Case for Switching
You spend roughly a third of your life in bed. The surface you sleep on affects your skin, your hair, your temperature, and the quality of your rest. Silk is not a luxury indulgence. It is a considered upgrade to something you do every single night.
Once you sleep on it, it is very hard to go back.
