Outline of chronohygiene

G Hildebrandt

    Chronobiologia
    |April 1, 1976
    PubMed
    Summary

    Chronohygiene, focusing on biological time structure, defines health as harmonious temporal organization. It highlights how disrupting rhythms, like through night work, impairs recovery and increases health risks.

    Area of Science:

    • Chronobiology
    • Preventive Medicine
    • Health Management

    Background:

    • Chronotherapy manipulates biological rhythms; chronohygiene extends this to health definition and prevention.
    • Health is viewed as an optimal, harmonious internal time structure integrated with environmental temporal orders.
    • Circannual and circadian rhythms influence health, therapy, activity, and recovery.

    Purpose of the Study:

    • To define health from a chronobiological perspective for chronohygiene.
    • To explore the role of biological rhythms in preventive healthcare and education.
    • To assess the impact of environmental factors, like night work, on biological time structure and health.

    Main Methods:

    • Conceptual analysis of chronobiology and chronohygiene principles.
    • Examination of circannual and circadian variations in relation to health and therapy.
    • Evaluation of the effects of disturbed time structures, such as from night work, on physiological rhythms.

    Main Results:

    • Health is characterized by a harmonious biological time structure.
    • Seasonal variations (circannual) create risk cycles affecting therapy and health.
    • Night work disrupts circadian rhythms, impairs recovery, and negatively impacts overall time structure and physiological responses.

    Conclusions:

    • Chronohygiene is essential for preventive health care by considering biological time structure.
    • Disturbances in the organism's time structure, especially from night work, compromise recovery and health.
    • The pulse-respiration-ratio can serve as a chronobiological marker for assessing risks associated with night and shift work.
