Why are some hotel sheets cold and some are not?

The materials of the sheets are different and the seasons are different.

General bed sheets are made of cotton, polyester and blended fabrics. The somatosensory sensation of sheets made of different materials will be different, and the somatosensory temperature will be different.

During the check-in season of the hotel, the temperature in different areas will also affect the temperature sense of the sheets. For example, in winter, the south usually feels wet and cold, and if there are corresponding heating measures, the north will be warmer.
