Abstract. Circadian rhythm disorders are disruptions in the div’s internal clock, affecting
sleep-wake cycles and various physiological processes. This article provides a detailed
examination of circadian rhythms, their biological underpinnings, and the impact of their
disruption on health and wellbeing. The article categorizes types of circadian rhythm disorders,
such as Delayed Sleep Phase Disorder (DSPD), Advanced Sleep Phase Disorder (ASPD), Shift
Work Disorder, and Jet Lag.
It also explores the causes, symptoms, and potential consequences of these disorders,
including increased risk for mental health issues, cardiovascular diseases, and metabolic
disorders. Treatment options, including behavioral interventions, light therapy, and
pharmacological approaches, are discussed. Understanding circadian rhythm disorders is crucial
for developing effective management strategies and promoting overall health.
Keywords: Circadian rhythm, sleep disorders, internal clock, health impact, treatment.
РАССТРОЙСТВА ЦИРКАДНОГО РИТМА
Аннотация. Расстройства циркадного ритма — это нарушения внутренних часов
организма, влияющие на циклы сна и бодрствования и различные физиологические
процессы. В этой статье подробно рассматриваются циркадные ритмы, их биологические
основы и влияние их нарушения на здоровье и благополучие. В статье классифицируются
типы расстройств циркадного ритма, такие как расстройство задержки фазы сна
(DSPD), расстройство опережающей фазы сна (ASPD), расстройство сменной работы и
смена часовых поясов.
В ней также изучаются причины, симптомы и потенциальные последствия этих
расстройств, включая повышенный риск проблем с психическим здоровьем, сердечно-
сосудистых заболеваний и нарушений обмена веществ. Обсуждаются варианты лечения,
включая поведенческие вмешательства, светотерапию и фармакологические подходы.
Понимание расстройств циркадного ритма имеет решающее значение для
разработки эффективных стратегий управления и укрепления общего здоровья.
Ключевые слова: циркадный ритм, расстройства сна, внутренние часы, влияние на
здоровье, лечение.
Introduction:
Circadian rhythms regulate numerous bodily functions, including sleep, hormone release,
and metabolism. Disruptions to these rhythms can lead to significant health issues.

Circadian rhythms are controlled by the suprachiasmatic nucleus (SCN) in the brain, which
responds to light and regulates hormonal and behavioral patterns.
Types of Circadian Rhythm Disorders
-Delayed Sleep Phase Disorder (DSPD): Difficulty falling asleep early and waking up.
-Advanced Sleep Phase Disorder (ASPD): Early sleep onset and wakefulness.
-Shift Work Disorder: Disruption due to work schedules that conflict with natural sleep
patterns.
-Jet Lag: Temporary condition resulting from rapid travel across time zones.
Causes and Symptoms
Causes include genetics, lifestyle factors, and exposure to artificial light. Symptoms range
from insomnia and excessive daytime sleepiness to mood disturbances.
Health Impacts
Circadian rhythm disorders are linked to various negative health outcomes, including
depression, anxiety, obesity, and cardiovascular diseases.
Treatment and Management
Treatments may involve cognitive-behavioral therapy for insomnia (CBT-I), light therapy,
melatonin supplementation, and lifestyle modifications focusing on regular sleep patterns.
Conclusion:
Awareness of circadian rhythm disorders is crucial for identifying at-risk populations and
implementing effective interventions, thereby improving public health outcomes.
