Cooling Pillow Case

Sleep Environment

Your body needs to drop its core temperature by 1–2°C to initiate deep sleep. When your sleep surface retains heat, that process stalls — sleep onset is delayed, slow-wave stages are shortened, and the cognitive recovery your brain runs overnight is cut short.

The Papryka Cooling Pillowcase works with your body's natural thermoregulation. Its open-weave construction disperses heat away from your head and neck throughout the night — keeping your sleep environment in the 16–19°C range research identifies as optimal for deep, restorative sleep.

• Active heat dispersion — open-weave fabric draws warmth away continuously
• Stays cool to the touch — no flipping required
• Standard and king sizes — fits most pillows
• Machine washable — no special care needed

One of the highest-leverage, lowest-effort changes you can make to your sleep environment. Works the first night.
