Why Sleeping Cool Matters—And How Your Pajamas Can Help

Why Sleeping Cool Matters—And How Your Pajamas Can Help

Designed for the way you sleep.

 

Your Body Was Built to Cool Down at Night

Ever wonder why you tend to get drowsy when it’s cooler—or why a hot room makes it hard to sleep? Note to self: Always make sure your Airbnb has working A/C. We're looking at you, Parisian apartment in July. 

It’s not random. It’s science.

As part of your natural circadian rhythm, your core body temperature drops slightly before and during sleep. This process—called thermoregulation—helps you fall asleep and stay asleep more deeply.

According to Psychology Today, the ideal room temperature for restful sleep is between 60–67°F (15–19°C). But even if you get the thermostat just right, your sleepwear (or if you’re lucky enough…your hormones!)  could be sabotaging your rest.

Most Sleepwear Traps Heat

You've probably come to think of cotton as the holy grail of underwear and pajamas, but what if we told you there is something better

Cellulocic fibers, like the lyocell we use in our A DOMANI sleepwear, are more moisture absorbent, quicker drying, softer, cooler and more breathable than cotton. They are also naturally antimicrobial!

Cotton may feel soft, but it tends to hold on to heat and moisture, and hence you feel like you’re pulling off a wet towel in the morning. And if you’ve ever wanted to wear your synthetic gym clothes to bed, we don’t recommend it unless you like ‘eau de gym locker’.  Midnight wakeups, tossing and turning, or waking up smelly and sweaty is no way to start off the day. 

That’s where we come in.

The A DOMANI Difference: Thermoregulating by Design

Our sleepwear is crafted with luxuriously soft MicroTENCEL™, a wood-based fiber that’s:

  • Naturally thermoregulating – adapts to your body temp to help you stay cool and comfortable

  • Breathable and moisture-wicking – no sweaty sheets or damp fabrics

  • Cool to the touch and exceptionally soft – It’s like a balm for overly sensitized skin.

  • Naturally antimicrobial = less laundry

Think of it as smart sleepwear—designed to support the way your body actually sleeps.

Why It Matters

Getting high-quality sleep isn’t just about comfort—it’s about health, focus, mood, and recovery. When your body is cool and undisturbed, you’re more likely to reach the deeper stages of sleep that help you truly restore.

And your pajamas? They’re the first layer in that equation. You deserve sleepwear that performs better than your sorority t-shirts and husband’s boxer shorts.
