A New Study Says There Are 4 Different Sleep Types. What's Yours?

You’re probably well aware of your personality type, like whether you’re an introvert or extrovert. You might even know your love language. But have you ever considered your sleep type?

Researchers from Pennsylvania State University recently released a study that helps people determine their sleep type and what it means for their overall health.

• Insomnia sleepers: Those who didn’t sleep for very long and had daytime sleepiness
• Nappers: Individuals who had good sleep but took frequent naps during the day

“I think that the four categories that they explained was a good way to kind of sum up the broad spectrum of what we see within clinical sleep disorders… and [the] kind of patients that come to our clinic,” said Dr. Kenneth Lee, the medical director of the University of Chicago’s Medicine Sleep Disorders Center. Lee was not affiliated with the study.

“Now, obviously, we don’t see the good sleepers. If you’re sleeping well, you’re not going to see a sleep doctor. But oftentimes, we see the other categories,” he said.

More than half of the study participants fell into the “suboptimal” napper or insomnia-sleeper categories. Throughout the 10-year study period,
