Most bed sheet is made of synthetic fibers.  When in use, these bed sheet create a large amount of static.  The skin will feel sticky and uncomfortable.

When large amount of static are stored inside the body, the positive and negative ions in the body will become unbalanced and will thus make human body uncomfortable. 

During sleep, the body will come in contact with the  cover of comforter which is usually made of cotton.  Cotton absorbs the moisture released from the human body and becomes wet.  The heat preservation of cotton is also relatively poor. Sometimes the human body can feel even colder after a while under the comforter.  And after leaving the bed for a while during the night, the comforter will quickly cool off.

This Smart Healthy Thermo Bed sheet will release moisture generated from the human body.  The body temperature is memorized and maintained by the super fine memory stainless steel fiber.  During winter night, after leaving the bed for a while coming back, the bed sheet is as warm as before.  There is a heat preservation layer between the bed sheet and the body, which will absorb the heat, and static released from the body and reach a condition of balanced positive and negative ions within the body.  It will thus improve blood circulation and make the sleep sweet and sound.

Notes:  This bed sheet is also flame resistance.  In case of fire, it can be used to protect body from being burned.
