Cooling pillows use a variety of technologies, including:
- Gel infusion: Absorbs and disperses heat.
- Phase-change materials (PCM): Maintain a consistent cool temperature by adjusting to body heat.
- Ventilated designs: Include air channels or breathable covers to enhance airflow.
- Cooling fabrics: Made from materials like bamboo or specialized fibers that wick away moisture and stay cool to the touch.
It’s important to note that pillows marketed as “cooling” do not have active cooling properties, they instead focus on not trapping heat from your face and head. This means that they will be breathable and wick moisture away, but they will not actively cool the temperature of your body or head.
