Do you ever look at the person driving the car next to yours or the person sitting on the subway next to you and wonder “what kind of sleeper is he/she?” Probably not. But what if you could determine even more about a person by knowing just a little about his/her sleep habits. The commonalities are based on sleep habits and more than 40 other factors including age, marital status, gender, employment status, diagnosed medical conditions, how often they feel tired/fatigued/not up to par, and the amount of caffeinated beverages consumed daily. Personalities were grouped into the following:

• Healthy, Lively Larks: You almost always get the sleep you need and you almost never feel tired or fatigued. You are younger than the other groups, often married or partnered and working full time. You consider yourself a morning person who is not diagnosed with a medical condition.
• Sleep Savvy Seniors: You are the most mature of the five groups (average age 60), about half are 65 or older. As a sleep savvy senior, you get the most sleep of any group, averaging 7.3 hours/night compared to 6.8 overall. Although many Sleep Savvy Seniors have been diagnosed with at least one medical condition, you do not feel you have a sleep problem, and you are less likely than other groups to be at risk for any sleep disorder.
• Dragging Duos: Dragging Duos are most likely to be partnered and employed, working more than 40 hours a week, and often doing job-related work within an hour of going to bed. As an early riser, you are nearly twice as likely as the other groups to get less sleep than you need to function at your best. More than one-third of Dragging Duos say they feel tired/fatigued at least three days each week.
• Overworked, Overweight and Overcaffeinated: As an evening person or “owl” who is employed, you have the longest work week of all the groups, and you are least likely to work regular day shifts. You sleep less than other groups but nap more, with two-thirds taking two or more naps each week. You feel like you need fewer hours of sleep each night to function at your best compared to the other groups and you believe you get as much or more sleep than you need.
• Sleepless and Missin’ the Kissin’: Your group has the largest proportion of “owls” and people who think they have a sleep problem or a symptom of insomnia. You are the least likely to say you frequently get a good night’s sleep. Nearly one-half of your group feels they are getting less sleep than they need, and the same number says they usually feel tired/fatigued.
