For cotton bedding, just like laundry, you should separate your lights and darks. Dark sheets should be washed in cool water, while light and white sheets can handle any temperature. For all else, pay attention to the manufacturer's instructions on the tag. Some bedding may even require dry cleaning. How often should you wash bedding? Weekly!
Fluorite (also referred to as "fluorspar") is the mineral form of calcium fluoride and can be found all over the world, including parts of Russia, China, South Africa, Canada, Mexico, the United States, and more, according to crystal expert and co-founder of Energy Muse, Heather Askinosie.. As she previously told mindbodygreen, "Fluorite has a …
