Sleep and Circadian Rhythm in Peripheral Inflammation: Realm of Interconnected Frontiers

Sleep, a fundamental physiological process, intricately links with various facets of health, extending beyond mere rest and rejuvenation. This chapter deals with the intricate interplay among sleep, circadian rhythm, and peripheral inflammation, investigating deep into their complex interactions. Extensive research underlines sleep’s pivotal role in regulating immune function and maintaining bodily equilibrium, with disruptions correlating to shifts in inflammatory markers and susceptibility to inflammatory diseases. Unraveling this intricate network necessitates a comprehensive understanding of the molecular mechanisms governing the processes, with cytokines, chemokines, and immune cells emerging as key players. Recent technological advancements shed light on the molecular underpinnings of sleep-induced immune modulation. Interruptions in sleep processes have been implicated in disturbing immune responses, thereby contributing to the development of inflammatory disorders. This chapter employs an interdisciplinary approach to dissect how sleep influences immune signaling and reciprocally, exploring its implications for chronic inflammatory conditions and potential therapeutic avenues. This further scrutinizes the impact of sleep duration, quality, and architecture on peripheral inflammation, as well as how inflammatory mediators reciprocally shape sleep patterns and processes. Understanding these intricate relationships holds promise for targeted interventions aimed at mitigating the repercussions of sleep disturbances on inflammation, and vice versa, thereby shaping the landscape of health and disease.
