Hot sleepers, rejoice. These cooling blankets will help you stay cool and comfortable in the heat of the night.

For those of you who toss off even lightweight comforters in the middle of the night because you’re sweating, a cooling blanket just may be the answer. In fact, you may want to pair it with cooling sheets and cooling pillows.

“Scientific studies show that we sleep better when it’s cooler,” says Dr. Smita Patel, DO, FAASM. “Instead of cooling down the entire house, though, a cooling blanket is more economically friendly. Also, many people don’t like to sleep with the air conditioning on because it can create a dry, uncomfortable environment to breathe in. A cooling blanket, especially when paired with a cooling mattress and a cooling mattress pad, is a great option all year round for hot sleepers and those experiencing night sweats. There are even cooling weighted blankets for those who like weighted blankets.”

According to Dr. Patel, cooling blankets work by absorbing the heat from your body while you sleep, then releasing it rather than trapping it and turning your bed into a sauna. Fabrics like cotton, linen, bamboo, and eucalyptus will wick moisture away, as will special technology like Outlast®, which was originally designed for NASA, and 37.5®, which has been proven to enhance athletes’ performance by keeping their core temperature at an ideal 37.5 degrees Celsius and a relative humidity of 37.5 percent.
