Merino Wool & Silk
Cuddling up in natural fibres doesn’t just bring peace of mind—it creates the conditions for deep, restorative sleep, from the earliest newborn days through old age.
There is something supportive in merino wool and silk. These fibres work in harmony with the body, helping us settle, rest, and truly restore.
A Foundation for Sleep
Research continues to point toward what many families historically experienced: babies sleep more peacefully in wool.
Studies have shown that underweight newborns experienced a 61% higher rate of weight gain when sleeping on a wool underlay than on a cotton one. In another observation, jaundiced newborns resting on wool were more settled—only around 30% cried, compared with 67% on cotton.
Researcher Dr. Paul Swan from the University of Sydney, a leading expert in Wool Science, reflects:
“Wool regulates your body temperature far better, keeping you in the ‘thermal comfort zone’. You not only fall asleep quicker, but sleep longer and more deeply.”
For a baby finding their way in the world, this kind of comfort can make all the difference.
Why Temperature Matters So Much
Babies and young children are still learning how to regulate their body temperature.
Because they lose heat more quickly than adults—up to four times faster—they can easily become unsettled when too warm or too cool. When this happens, their bodies use valuable energy just to maintain warmth.
Merino wool helps keep our bodies in that steady, balanced place—neither too hot nor too cold. When the body can rest in comfort, energy can go toward growth, development, and gentle restoration.
The result is often what every parent hopes for:
longer sleeps, deeper rest, and a more settled child.
Breathable, Living Fibres
Merino wool is often called an “active” fibre—and for good reason.
It responds to the body, adjusting to changes in temperature and environment. Unlike synthetic materials, which can trap heat and moisture, merino allows the skin to breathe naturally.
Blending merino with silk adds softness and lightness—ideal for sleepwear worn close to the skin. The result is a fabric that feels calm, gentle, and unobtrusive, supporting rest without distraction.
Dry Comfort Through the Night
One of merino’s most remarkable qualities is its ability to manage moisture.
It can absorb up to 35% of its own weight in moisture while still feeling dry to the touch. This helps maintain a comfortable microclimate between the body and the fabric—especially important for babies and children who may perspire during sleep.
Instead of waking from dampness or overheating, children remain dry, warm, and settled.
For women moving through menopause, wool offers support. As the body’s temperature shifts, merino helps to release excess heat and gently restore warmth, reducing that hot, clammy feeling. Its natural breathability and moisture management can support more comfortable, uninterrupted sleep during this time of change.
From Babies to Grown Ups
While these benefits are meaningful in the newborn stage, they don’t end there.
Children also thrive when their sleep environment supports natural regulation. Whether it’s a baby in their first months, a toddler transitioning to longer nights, or a child needing deep rest after full days outdoors, merino wool and silk offer support.
Base layers, sleepwear, and breathable bedding all contribute to a rhythm of rest that feels grounded and easy.
Shift to Support Rest
If a baby or child is unsettled, it’s not always obvious why. Sometimes, the smallest environmental changes—what they are sleeping on, or wearing—can have a meaningful impact.
Choosing natural fibres like merino wool and silk is an easy step toward creating a more supportive sleep environment.
And in that space, rest comes more easily.
As Dr. Paul Swan reminds us:
“Anything that helps sleep is beneficial for both mental and physical health.”
