Efeito da privação de sono sobre a modulação autonômica cardíaca: uma revisão narrativa

Abstract

Currently, the lifestyle leads to sleep deprivation, fewer hours of sleep. These changes, alone or in association with extrinsic factors, can result in autonomic changes and increase the risk of cardiovascular diseases. In this sense, the present study is a narrative review, which aimed to understand what the specialized health literature, from the last 10 years (2013 to 2023), brings about the effects of sleep privatization on the control of the ANS . Searches for articles were carried out in the VHL, SciELO, LILACS and PubMed databases using the descriptors: sleep deprivation, sleep disorders, sleep quality, ANS and dysautonomia, as well as their English counterparts. After selecting the publications, analyzes were carried out according to the precepts of the theme. Studies demonstrate that

sleep deprivation triggers ANS imbalance, leading to a prevalence of sympathetic responses and a reduction in parasympathetic functions. These effects have significant short- and long-term health implications, increasing the risk of cardiovascular and metabolic diseases and compromising the body's ability to efficiently deal with environmental stressors.
