The weighted blanket has a laminated structure comprising: a bottom sheet; a top sheet having electromagnetic field (EMF) shielding embedded therein; a batting layer between the sheets; and Far-Infrared-emitting bioceramic beads. The blanket is quilted to retain the beads in quilted pockets. The blanket provides FIR emissions to the user, while protecting them from external EMF. ## Claims ### Claim 1 A weighted blanket having a laminated structure comprising: a bottom sheet; a top sheet having electromagnetic field (EMF) shielding embedded therein; a batting layer and Far-Infrared-emitting bioceramic beads between the sheets, wherein the laminate structure is quilted together to join the layers and retain the beads in quilted pockets. ### Claim 2 (depends on 1) The blanket of claim 1, wherein the bioceramic beads have a cumulative weight of 8 to 15 kgs. ### Claim 3 (depends on 1) The blanket of claim 1, further comprising a second batting layer between the sheets, the two batting layers arranged to sandwich the ceramic beads therebetween. ### Claim 4 (depends on 1) The blanket of claim 1, wherein the batting layer(s) is made of a non-glue cotton having air pockets that entrain the beads. ### Claim 5 (depends on 1) The blanket of claim 1, wherein the top sheet comprises metal threads or metal nanoparticles embedded on fabric threads to block EMF waves, the metal preferably selected from one of: silver, iron, steel, nickel or copper. ### Claim 6 (depends on 1) The blanket of claim 1, wherein the bottom sheet comprises FIR-emitting materials. ### Claim 7 (depends on 1) The blanket of claim 1, wherein the FIR-emitting bioceramic beads comprise one or more of: tourmaline ceramic beads, alkaline ceramic beads, titanium dioxide ceramic beads, graphene ceramic beads, maifan stone ceramic beads, negative ion ceramic beads, silver ion ceramic beads, sepiolite, quartz, kaulin, and charcoal. ### Claim 8 (depends on 1) The blanket of claim 1, further comprising a closable aromatherapy pocket, preferably located on the top sheet, preferably wherein the aromatherapy pocket is made of a porous material to permit passage therethrough of aerosolized aromatherapy particles. ### Claim 9 (depends on 1) The blanket of claim 1, wherein one or more margins of the blanket do not include beads, preferably wherein the margin has a width between 5 cm and 15 cm. ### Claim 10 A method of manufacturing a weighted blanket comprising: providing a first fabric layer; overlaying the first fabric layer with a batting layer; overlaying the batting layer with second fabric layer; distributing Far-Infrared-emitting bioceramic beads substantially evenly between the batting and one of the fabric layers; and quilting the layers to retain the beads in quilted pockets, wherein one of the fabric layers comprises electromagnetic field (EMF) shielding embedded therein. ### Claim 11 (depends on 10) The method of claim 10, further comprising embedding threads of the top sheet with metal nanoparticles, the metal preferably selected from one of: silver, iron, steel, nickel or copper. ### Claim 12 (depends on 10) The method of claim 10, further comprising providing a second batting layer over the first batting layer to sandwich the bioceramic beads therebetween; ### Claim 13 (depends on 10) The method of claim 10, wherein quilting is performed by sewing or gluing. ### Claim 14 (depends on 10) The method of claim 10, wherein the bioceramic beads have a cumulative weight of 8 to 15 kgs. ### Claim 15 (depends on 10) The method of claim 10, wherein the batting layer(s) is made of a non-glue cotton having air pockets that entrain the beads. ### Claim 16 (depends on 10) The method of claim 10, wherein the bottom layer comprises FIR-emitting materials. ### Claim 17 (depends on 10) The method of claim 10, wherein the FIR-emitting bioceramic beads comprise one or more of: tourmaline ceramic beads, alkaline ceramic beads, titanium dioxide ceramic beads, graphene ceramic beads, maifan stone ceramic beads, negative ion ceramic beads and silver ion ceramic beads. ### Claim 18 (depends on 10) The method of claim 10, wherein the FIR-emitting bioceramic beads comprises material selected from: sepiolite, quartz, kaulin, and charcoal. ### Claim 19 (depends on 10) The method of claim 10, further comprising providing a closable aromatherapy pocket on one of the fabric layers, preferably made of a porous material to permit passage therethrough of aerosolized aromatherapy particles. ### Claim 20 (depends on 10) The method of claim 10, wherein the beads are not distributed over one or more margins of the blanket, preferably wherein the margin has a width between 5 cm and 15 cm.
