The Science of Sleeping Cool: How Temperature Impacts Your Sleep Quali – Stitchco

Let’s talk temperature - specifically, why you sometimes wake up at 2 in the morning, hot and uncomfortable, tossing and turning, desperate for some relief. We all know the simple joy of turning your pillow over to the cool side. That momentary relief can sometimes be all you need to settle in and drift off to sleep.

Unfortunately, most pillows only offer that - momentary relief - before they start to trap warmth and the heat and discomfort creep back in again, waking you up late at night and turning the next day into a drag.

Making small changes to your sleep environment is one of the easiest ways to get better sleep, and temperature is one of the biggest factors. But it’s not just about adjusting your thermostat! Learn how your pillow can help keep you sleeping cool and comfortable through the night.

🌙 Your Body Loves Cooling Down at Night

Did you know, as part of the natural circadian rhythm, your body temperature changes throughout the day? As your body prepares for sleep, your core body temperature naturally drops. It’s one of the signals your body uses to enter that cozy, restorative sleep mode.

Too much heat? Your body has a harder time completing that process — and you end up tossing, turning, and hunting for the “cool side” of the pillow.

Once you are asleep, your core temperature continues to drop throughout the night, reaching its lowest temperature between 2-4 am, and then rising a couple of hours before you wake up, signaling your body to start the day. Interrupting that cycle with a too-warm sleep environment can have serious consequences for your rest. If your core body temperature is too warm, you may struggle to enter the deep, restorative sleep you need to wake feeling rested and ready for the next day. [1]

🌬️ Why Your Pillow Matters

Pillows can either help regulate temperature… or trap heat like a thermal blanket you didn’t ask for. Your body releases heat through your extremities, like your arms, legs, and yes, your head. This means that your pillow is the first line of defense in keeping your body temperature regulated.

A cool-sleeping pillow supports a more comfortable night by:

Allowing air to flow through
Wicking away heat
Minimizing moisture
Staying cool to the touch

We chose to create our pillows with Talalay latex, a naturally temperature-regulating material, and designed the Stitchgrid core with built-in airflow, to help support your sleep. At StitchCo, we’re big fans of breathable materials because a cool pillow = a calmer night.

❄️ Tips for Cooler Sleep

Keep your room between 65–68°F — your body will thank you.
Choose bedding that breathes, not suffocates.
Opt for pillows with airflow-friendly fill.
Keep a consistent bedtime so your body temperature follows a predictable rhythm.

When temperature works with your body instead of against it, sleep feels effortless.

✨ The StitchCo Take on Getting Cooler Sleep

Cool sleep isn’t about blasting the AC — it’s about creating a naturally breathable sleep environment from the pillow up. That’s why we design our pillows to help keep airflow moving, so your nights stay comfortable, refreshing, and blissfully wake-up free.
