The Science of Cooling Bedding: How Temperature Affects Your Sleep

Why Temperature Plays a Key Role in Sleep Quality

Getting a good night’s sleep isn’t just about having a comfy bed — it’s also about regulating your body temperature. As you drift off to sleep, your core body temperature naturally drops to help 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 in — and on — make a world of 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 — due to heat-retaining fabrics like polyester or heavy weaves — your body can struggle 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 patent-pending blend of eucalyptus, pine and mint fibres goes a step further. The mint activates cold-sensitive receptors in your skin, providing an instant cooling sensation that helps you fall asleep faster. Eucalyptus draws moisture away from the body, and pine gives our fabric its silky-soft strength — all while being naturally antibacterial, hypoallergenic and vegan.

Why Overheating at Night Is More Common Than You Think

Overheating is one of the most common (and overlooked) reasons for poor sleep. Whether it’s due to synthetic materials, stacked bedding, night sweats or hormonal shifts, heat build-up can disrupt sleep stages and prevent your body from reaching REM. 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 culprit.

How Mynt Lab's Cooling Technology Works

Mynt Lab’s MyntFusion™ fabric is the first of its kind, created after 18 months of research and development. It’s engineered to cool naturally, without chemical additives or synthetic finishes. The combination of FSC-certified plant fibres provides breathable airflow, odour resistance and moisture control. Plus, it maintains its cooling performance even after 200+ washes — unlike many “cooling” synthetics that lose effectiveness over time.

Benefits Beyond Comfort: Sleep, Skin and Sustainability

Cooling bedding doesn’t just feel good — it supports your health. Staying cool at night reduces the risk of acne, irritation and overheating, which can disrupt your natural circadian rhythm. It’s also a sustainable choice. Our production process recycles 99% of water and solvents, and our materials are biodegradable, vegan and cruelty-free. Better sleep, better skin, better for the planet.

Final Thoughts: Upgrade Your Sleep Environment

If you’re struggling to stay asleep or constantly wake up hot, it might be time to rethink your bedding. Cooling fabrics like those used by Mynt Lab help regulate temperature naturally — giving you deeper, more restorative sleep. It’s not just luxury — it’s sleep science.
