As soon as you lie on the pillow, the cooling cover absorbs your body heat. Due to the heat absorption, the cooling cover does not feel as cold as before use.

However, this does not affect the cooling effect of the cover:

The absorbed heat is released into the air via the exposed cushion surface, so that the cushion cover can absorb further heat from your body. Thanks to this constant cycle of heat absorption and release, your head is cooled continuously.

After use, the cooling cover recovers within a few minutes and reaches its initial cooling strength.

The balanced dosage of the cooling effect prevents you from waking up with muscle stiffness or other discomfort due to too much cooling the next morning.
