A new study looked into “America’s preferred sleep temperature”, and overall, the IDEAL TEMPERATURE at sleep time is 67 degrees Fahrenheit. Rhode Island likes it the next coolest, followed by Oregon, Connecticut, Vermont, Washington, Maine, West Virginia, New Hampshire, and Arkansas. On the flipside, Hawaii likes it the WARMEST at 70 degrees, which isn’t even THAT warm. (At least to someone who spent a lot of their life without A.C.)Florida likes it the next warmest, followed by Texas, Maryland, Arizona, Utah, Iowa, Minnesota, Ohio, and Nevada. And the states that get the BEST sleep are: Nevada, Indiana, Vermont, California, and South Dakota.
