Getting a good night's sleep isn't just about having a comfortable mattress. It's also about regulating your body temperature.
As you drift off to sleep, your core body temperature naturally drops to signal that it's time to rest. If your bedding traps heat or makes you feel clammy, it can interrupt this process and cause fragmented sleep or early wake-ups.
That's why the fabrics you sleep on make a real difference.
The Science Behind Sleep and Thermoregulation
Your body is hardwired to cool down slightly before and during sleep. This dip in core temperature helps you fall asleep faster and stay in deeper, restorative stages of sleep.
But when your sleep environment is too warm, whether from heat-retaining fabrics like polyester or heavy weaves, your body struggles to regulate itself. This leads to tossing, turning, and disrupted sleep cycles.
Studies have shown that people sleep more soundly in environments between 16°C and 20°C. That's where cooling bedding steps in: by helping to dissipate excess heat, wick away moisture, and keep your skin temperature in an ideal zone for uninterrupted sleep.
What Is Cooling Bedding?
Cooling bedding is designed to help your body maintain an optimal temperature throughout the night. Unlike traditional materials that trap heat, cooling fabrics are lightweight, breathable, and moisture-wicking.
At Mynt Lab, our proprietary MyntFusion™ fabric goes a step further. It combines:
- Eucalyptus (TENCEL™ Lyocell) to draw moisture away from the body
- Pine (Naia™) for silky-soft strength and durability
- Mint infusion that activates cold-sensitive receptors in your skin, providing an instant cooling sensation
The result is a fabric that's naturally antibacterial, hypoallergenic, and lab-tested to feel 3x cooler to the touch than cotton (Q-max score of 0.34).

Why Overheating at Night Is More Common Than You Think
Overheating is one of the most common, and most overlooked, reasons for poor sleep.
Whether it's due to synthetic materials, layered bedding, night sweats, or hormonal shifts, heat build-up can disrupt sleep stages and prevent your body from reaching deep, restorative rest.
Many sleepers don't realise their bedding is working against them. If you regularly wake up hot, restless, or clammy, your sheets could be the problem.
How MyntFusion™ Cooling Technology Works
MyntFusion™ is the first fabric of its kind, developed after 18 months of research and testing. It's engineered to cool naturally, without chemical additives or synthetic finishes.
Lab-tested performance:
- 3x cooler to the touch than cotton (Q-max 0.34)
- Up to 99.7% antibacterial, keeping sheets fresher between washes
- Moisture-wicking to prevent that clammy, damp feeling
- Maintains cooling performance after 200+ washes, unlike synthetic "cooling" fabrics that lose effectiveness over time
The mint infusion is embedded into the fibres themselves using micro-encapsulation, so it doesn't wash out.
Who Benefits Most from Cooling Bedding?
Cooling bedding is especially helpful if you:
- Wake up hot or sweaty, even when the room is cool
- Experience night sweats due to menopause, medication, or hormones
- Sleep next to a partner who runs hot
- Live in a warm climate or don't have air conditioning
- Have tried "cooling" sheets before and been disappointed
Beyond Comfort: Sleep, Skin, and Sustainability
Cooling bedding doesn't just feel better. It supports your health.
Staying cool at night reduces the risk of irritation and overheating, which can disrupt your natural circadian rhythm. And because MyntFusion™ is antibacterial, it helps keep your sleep surface cleaner for longer, which is better for sensitive and acne-prone skin.
It's also a more responsible choice. Our production process recycles 99% of water and solvents, and our fibres come from FSC- and PEFC-certified sustainable forests.
