A circadian rhythm is a roughly-24-hour cycle in the physiological processes of living beings, including plants, animals, fungi and cyanobacteria. The term 'circadian', comes from the Latin circa, 'around', and dies, 'day', meaning literally 'about a day'. The formal study of biological temporal rhythms such as daily, weekly, seasonal, and annual rhythms, is called chronobiology. In a strict sense, circadian rhythms are endogenously generated, although they can be modulated by external cues such as sunlight and temperature. Most of a person's body systems demonstrate circadian variations. The body systems with the most prominent circadian variations are the sleep-wake cycle, the temperature regulation system, and the endocrine system. The malfunctioning of a person's circadian system, or biological clock, causes circadian rhythm disorders. Circadian rhythms and their relation to health outcomes in the globalised hyper world of the 21st century are now understood to be extremely important.

Circadian clocks are endogenous and temperature-compensating timekeepers that provide temporal organization of biological processes in living organisms. Circadian rhythms allow living organisms to adapt to the daily light cycles associated with Earth's rotation and to anticipate and prepare for precise and regular environmental changes. This book discusses the fundamental advances of how the circadian clock regulates critical biological functions as well as the cellular and molecular mechanisms controlling circadian rhythm in living organisms. It also provides new insights into and sheds new light on the current research trends and future research directions related to circadian rhythm. This book provokes interest in many readers, researchers and scientists, who can find this information useful for the advancement of their research works towards a better understanding of circadian rhythm regulatory mechanisms.

Circadian rhythms are biological processes displaying endogenous and entrainable oscillations of about 24 hours. They are driven by a group of genes called clock genes that have been widely observed in plants, animals and even in bacteria. In mammals, the core clock genes are rhythmically expressed in both the suprachiasmatic nucleus (SCN), the master clock residing in the hypothalamus, and almost all peripheral tissues where they control numerous target genes in a circadian manner, and thus affect many physiological and biochemical processes. Evidence suggests that disruption of the circadian rhythms (or desynchronization) is a significant risk factor for the development of metabolic diseases, cardiovascular diseases, cancer and sleep disorders. Evidence also suggests that the disruption suppresses immune function and increases vulnerability to infectious diseases. Restoring or strengthening the circadian rhythm may be therapeutic for these conditions. This becomes exceptionally important in modern societies because many people are suffering from frequent desynchronization due to shift working, exposure to artificial light, travel by transmeridian air flight, and involvement in social activities. Besides, the temporal variations in the incidence and severity of many diseases, such as the onset of cardiovascular events, chronic obstructive pulmonary disease (COPD), inflammatory diseases and mental disorders have also drawn increasing attention to the circadian clock. The circadian rhythms affect not only the health status, but also the drug efficiency. The effects (and side effects) of many drugs vary with biological timing. The tolerance of many medications displays circadian variation as well. The timing of medical treatment in coordination with the body clock may significantly increase the desired effects of drugs, and lower the dose and toxicity. In addition, circadian rhythms can also be modulated by some therapeutic drugs, for example, melatonin and modafinil, which are used to treat circadian rhythm sleep disorders. In this Research Topic, we assemble a series of critical review and research articles that focus on the therapeutic implications of circadian rhythms. Topics include, but are not limited to: • Circadian disruption caused diseases or disorders and related intervention • Temporal manifestation of diseases or disorders and therapeutic implications • The effects of circadian rhythms on drugs • The effects of drugs on circadian rhythms

"Circadian rhythm is the mechanism for measuring time by organisms in units of around 24 hours. Almost every organism has the ability to predict daily events such as sunrise and sunset, which is essential for their optimal survival strategies. Circadian rhythms persist even in the absence of time cues and ensure that behavioral, physiological and metabolic processes align with changing environmental conditions. Most organisms, irrespective of whether they are prokaryotic or eukaryotic, have evolved certain mechanisms to sense their external environment in order to prepare a biological response. Often, these biological responses result in changes in physiology and biochemistry of organisms for the optimization of their survival. There is no unified mechanism among organisms by which sensory environment can be applied to control their lifespan. In humans, disruptions of the circadian rhythm may have an increased risk of age-related neurodegenerative diseases such as cancer, diabetes, etc. This book encompasses the most recent knowledge and modern trends in the field of circadian rhythms research. It is also expected to provide a must-read guide for beginners as well as advanced researchers in this field of study. Undergraduate, post-graduate and research scholars of several disciplines such as chemistry, botany, microbiology, biochemistry, biotechnology, bioinformatics, life sciences and bionanotechnology will benefit from this book"--

Biological rhythms time the ebb and flow of virtually every physiological process, and their mutual coordination guarantees the integrity of the organism over space and time. Aging leads to the disintegration of this coordination, as well as to changes in the amplitude and/or frequency of the underlying rhythms. The results of this are accelerated loss of health during aging, and in experimental model systems curtailed lifespan occurs. This book will examine the machinery that constitutes circadian systems and how they impact physiologic processes. It will also discuss how disturbances of circadian rhythms can lead to complex diseases associated with aging. Much of this treatment will focus on metabolism and genome stability. Importantly, the chapters in this book will encompass work in several different models, in addition to human. The book will conclude with a discussion of modeling approaches to biologic cycles and chronotherapy, for future research and translation.

This edited volume focuses on the interplay between sleep and circadian rhythms with health, aging and longevity. Sleep is absolutely important for human health and survival, as insufficient sleep is associated with a plethora of conditions, including the poor quality of life, onset of several diseases, and premature death. The sleep–wake cycle is an evolutionary conserved neurobiological phenomenon, and is a prominent manifestation of the biological clocks localised in the suprachiasmatic nucleus (SCN). Understanding bidirectional relationship between sleep and circadian rhythms is of utmost importance and urgency, especially in the context of modern lifestyle where sleep is often out of phase with the internal body clocks, social jetlag, artificial lights and so on. The 25 chapters by leading researchers and experts from 11 countries are arranged into seven sections: understanding sleep and clock interlink in health and longevity; sleep, aging and longevity; clock, aging and longevity; melatonin, sleep and clock; genetic regulation of sleep and clock; therapeutic interventions in sleep disorders and clock misalignment; and experimental models to study sleep and clocks in aging and longevity. This book is useful for advanced undergraduate and graduate students, and researchers, educators, and other biomedical professionals.
