What is a Chronotype?

The concept of chronotype is almost 50 years old and was born with Öquist, who adopted it for the first time in his thesis in 1970.

O. Östberg and J. Horne revised this questionnaire in the following years, publishing the morningness-eveningness questionnaire (MEQ), which is still in use nowadays to understand if a person’s circadian rhythm produces a peak of alertness in the morning or the evening.
