Living Style
Definition & theoretical foundation
Living Style integrates two traditions. From Alfred Adler (Lebensstil, Individual Psychology, 1929) it inherits the organising pattern of daily life: the stable way each person structures time, energy and relationships, reflecting values and life goals. From modern chronobiology it inherits chronotype, formalised by Horne & Östberg (1976) in the Morningness-Eveningness Questionnaire and refined by Roenneberg through the Munich ChronoType Questionnaire, which measures endogenous circadian rhythms and social jetlag (the mismatch between biological clock and social demand). To this base add dimensions of social energy (introverted/extroverted consumption), eating habits, physical activity and routine intensity versus spontaneity. The whole describes how a person lives, beyond what they are.
What you'll learn about yourself
You receive your chronotype (morning, intermediate or evening) computed from your answers, with the window in which your cognitive peak typically falls. Alongside it, a social jetlag indicator measures the gap between your ideal biological schedule and your actual social schedule, with a reading of the clinical signals associated when the value is high. The app translates your social-energy level into high, medium or low, based on how many close contacts you consume per week, and qualifies your routine intensity as structured, mixed or flexible, according to how much your daily life is orchestrated by habit versus improvisation. It adds your declared eating patterns (cooking at home, eating out, restrictions) with a read on relational impact, a map of physical activity and regular hobbies, and your weekend pattern (restorative rest or active adventure) in dialogue with your chronotype. It closes with suggestions: small adjustments to reduce social jetlag or align your rhythm with your productive peak.
Limitations & caveats
Chronotype has robust empirical support: heritability near 50% and predictable variation with age (Roenneberg). Social-energy and routine-intensity dimensions rely on self-report and are subject to cultural bias and social desirability. Living style shifts with life stages (children, career change, health), so periodic reassessment is advised. Alignment on non-negotiable dimensions (sleep, social rhythm) has strong predictive value, above situational complementarity.
