These Copper-Infused Bed Sheets Will Keep You Cool (and Bacteria-Free) All Summer Long

Everyone needs a comfortable, quality night's sleep, and while we often consider our mattress to be the biggest factor, perhaps we should spend more time thinking about our sheets. Right now, as warmer weather is approaching and you may be swapping your winter flannels for summer cotton, a new brand has launched a Kickstarter campaign promising cool, comfortable bedding during those sweaty summer nights.

The sheets and pillow cases from Savmos are made with high-end cotton-bamboo-blend fabric to provide an ultra soft feel. The key component, though, is the copper-infused fibers imbedded in the weave. The copper serves as a dispersion conductor, pulling your body heat away from you and distributing it more evenly across the surface area of your bed. This helps regulate your body temperature as you sleep, allowing you to sleep more comfortably and not wake up in a sticky pool of your own sweat.

And to top things off, the copper in the sheets naturally repeals dust mites and other allergens, and is said to be 99.4 percent antibacterial. Our oft-neglected sheets can become a breeding ground for bacteria if they aren't washed often enough. Savmos sheets promise to not only control moisture and airflow throughout the nights, but naturally stave off bacterial growth between laundry days.

The sheets are offered in twin, king, and queen sizes with prices ranging from $150 to $325 for a full set. Pillow cases come in two sizes, starting at $39. You can check them out here on Kickstarter.

Mastering new languages can open up new ways to communicate with others you may have not been able to before, and over the past few years, studies have shown that being multilingual can help slow cognitive decline and strengthen neural pathways as you age.

Alongside using a program like Rosetta Stone to learn a language, it can help to have periodic conversations in the dialect you’re studying—even if they are with yourself. Check out our other tips for mastering another language.
