Two Usage Ways: This grounding blanket is designed for 2 usages: grounding blanket and grounding sheet.The size is 55*80 inch, which is large enough as a blanket when you are napping and also is large enough as a bed sheet for a queen size bed. [PREMIUM MATERAIL]: The grounding sheet has 2 layers which are made with conductive silver fiber fabric as lining and extra soft flannel fabric as exterior. The white conductive fabric has 95% cotton and 5% silver fiber and the grey flannel fabric is very comfortable and warm enough as a napping blannket. When we use it as the grounding blanket or the bed sheet, we need have bare skin touching the grey fabric to grounding. Health Benefits: Sleeping with our grounding bed sheet is so much more than just better sleep. When you feel your body producing a positive change, it's a start with a strong nature cure energy of earth to enter your body. Grounding also helps us to reduce pain to help with arthritis, sprains, strains, back pain and more. Grounding Connection: The Grounding bed sheet connects to the Earth via a UK grounding cord and a ground socket of the wall electrical outlet while we are sleeping. When we are grounding, the positive and negative ions are attracted to clump together and the negative ions enter the human body to keep our health and better sleep. Wash & Care: Washing the sheet weekly or twice per month with warm water and liquid detergent. No bleaching, no softeners and whitening detergents. Both hand and machine wash are ok. Safe & Secure: We won't necessarily feel any instant sensations as it is completely natural using NO electricity.
