What does the Munich Chronotype questionnaire measure?
Measuring chronotype is helpful to diagnose circadian rhythm sleep-wake disorders. The Munich Chronotype Questionnaire (MCTQ) is a self-reported measure of chronotype that calculates the midpoint of sleep on free days based on self-reported bed and wake times. Self-reports of sleep are prone to bias.
How do you determine Chronotype?
Chronotype calculation
An individual’s chronotype can be assessed by mid-sleep on work-free days (MSF) [1]. Mid-sleep is calculated as the halfway point between sleep onset and sleep offset, for example, assuming an 8h sleep duration, a chronotype of 4:00 falls asleep at midnight and wakes up at 8:00 the next day.
Are sleep Chronotypes real?
Chronotype is the natural inclination of your body to sleep at a certain time, or what most people understand as being an early bird versus a night owl. In addition to regulating sleep and wake times, chronotype1 has an influence on appetite, exercise, and core body temperature.
What is chronotype in psychology?
Chronotype refers to individual differences in sleep timing and in preferences for a given time of day while sleep duration refers to the hours of sleep.
What is the rarest chronotype?
the dolphin

What are the 4 chronotypes?
People typically fall into one of four chronotype categories: the bear, the wolf, the lion, and the dolphin. Each chronotype is loosely based on the relative animal’s sleep patterns and habits, so let’s dive in to discover which chronotype you most closely align with.
What is the most common chronotype?
Bears
Bears are the most common chronotype—about 50 percent of the adult population are Bears. Because it’s the most common chronotype, Bear time has a dominant influence over our broader social time. Six o’clock is the standard dinner hour because that’s when Bears are ready for their evening meal.
How do you eat for chronotype?
How time-restricted eating can help you, based on your chronotype.
- With a time-restricted diet, you eat within an 8- or 12-hour window which can increase your metabolism and help you lose weight.
- Your unique biological clock — or, chronotype — determines when you naturally sleep and eat.
