It's a proven fact that a low body temperature is the key to a good night's sleep. In fact, research has shown that we get the best sleep when a room is between 60 to 67 degrees Fahrenheit—which can be hard to come by in the summertime, no matter how hard your poor air conditioner is working.

So, you can imagine how surprised we were to learn that the answer to a good night's sleep, even in the midst of a heatwave, could come in the form of an extra piece of clothing.

Now, before you get too worked up, don't worry: we're not about to suggest putting any additional items on your body. We're not crazy! But we'd by lying if we said that a brilliant tip from Apartment Therapy didn't have us rummaging through our sock drawer.

WATCH: This Is the Best Temperature for Sleep, According to a Sleep Doctor

For one writer, sticking a sock filled with rice in the freezer to use as a cold pack was all it took to get her sleeping soundly through the sweltering heat. How? Well, frozen rice socks have two important qualities that traditional ice packs do not: a soft fabric buffer and the ability to form around you as you sleep. It's like a DIY heating pad, but reversed!

To make one, simply place a sock (thin dress socks work particularly well) filled with rice in the freezer every morning when you wake up, or a few hours before bedtime. Take it out just as you're ready to hit the hay. According to Apartment Therapy, the sock should stay cold for approximately 20-30 minutes—just enough time for you to drift off peacefully off to sleep.
