One night you’re staring at the ceiling for an hour, willing your eyelids to feel heavy. The next you conk out immediately—only to wake up and see the numbers 4-0-0 glowing on your alarm clock. Sound familiar? Sadly, it’s the status quo for American women, 67 percent of whom report trouble sleeping multiple times a week, according to the National Sleep Foundation (NSF). But not all members of the fairer sex wage this battle: In its most recent international poll, the NSF found that our counterparts in Mexico, Germany, the U.K. and Canada doze regularly—and with relative ease. Women in America? We’re sleeping an average 30 to 40 minutes less per night than our peers abroad. We looked at the data and tapped experts to find out what foreigners are doing differently and why it works. Read on and slumber soundly (at last!).
