Night sweats: silk, cotton or TENCEL™ lyocell

Waking up at night with a feeling of dampness, heat, or discomfort is more common than you might think.
Night sweats are not always related to room temperature: the material in contact with the skin plays a key role .

Silk, cotton or TENCEL™ Lyocell: here's how to choose the most suitable linen for better sleep, even when nights are restless.

Why do we sweat at night?

Night sweats can have several causes:

more sensitive temperature regulation during sleep,
a room that is too heated or poorly ventilated,
materials that retain moisture,
excessive friction on the skin.

👉 When the material absorbs moisture without wicking it away, the feeling of dampness persists — and sleep becomes less restorative.

Which material is the most comfortable when you sweat at night?

The best material is one that regulates temperature, wicks away moisture, and remains soft on the skin.
They do not all react in the same way.

Cotton against night sweats

Cotton is often seen as a safe investment. However:

It absorbs moisture , but retains it.
Once wet, it can become cold or sticky .
Friction is more pronounced, especially on sensitive skin.

👉 Cotton is suitable for sleepers who are not prone to sweating, but shows its limitations when nights become warmer or more humid.

Silk: thermoregulation and natural softness

Natural silk has a unique protein structure that allows it to:

regulate body temperature ,
to stay cool when it's hot and at a comfortable temperature when it's cooler.
to limit friction on the skin,
to offer a dry and enveloping sensation.

It is particularly appreciated in cases of light to moderate perspiration, and for sensitive or reactive skin.
👉 It accompanies the body without imprisoning it.

TENCEL™ Lyocell: breathability and a “clean” feel

TENCEL™ Lyocell — which we at CÉTOILE call vegetable silk — is known for:

its high breathability ,
its ability to quickly wick away moisture ,
its smooth and cool surface,
its “clean” and dry feeling on the skin.

Unlike cotton, moisture does not stagnate in the fiber.
👉 The fabric remains fluid, even after several hours of sleep.

Silk or TENCEL™: which to choose depending on your sleep?

Light perspiration, sensitive skin → silk provides softness and regulation.
Increased perspiration → TENCEL™ Lyocell ensures freshness and wicking.
Irregular nights, temperature variations → both materials offer superior comfort to cotton.

👉 The choice depends less on the season than on your sleeping habits .

The choice according to Maison CÉTOILE

At CÉTOILE, we made the choice of a founding duo:

Natural silk , for its softness and regulating properties.
TENCEL™ Lyocell , for its breathability and plant-based comfort.

Two materials designed to support the body, without ever restricting it.
