What’s Your Sleep Type?

Identify yourself as an early riser, a late-night individual, or perhaps somewhere in the middle with our "chronotype" assessment tool.

Early risers hit the ground running, while night owls prefer to wait for the evening hours to get productive.

Scientists refer to this innate inclination as a chronotype, shaped by the body's internal clock, or circadian rhythm, which in turn influences energy levels, hormone regulation and hunger patterns.

Individuals whose internal clocks clash with societal expectations often struggle to stay alert during daily activities like education, employment or social gatherings. Unbeknownst to many, their unique sleep patterns remain unidentified, according to Dr. Michael Terman, a psychologist specializing in chronobiology based in New York City.

Discover your unique sleep type with this quiz, a tool used by Dr. Terman in his studies.

The Morningness-Eveningness Questionnaire, developed by Michael Terman and his team in 2005, built upon the foundational work of J.A. Horne and O. Ostberg's original questionnaire from 1976. This adapted quiz was made available to The with permission, where it was enhanced with bird labels.
