Sleep duration and mortality

摘要

Sleep patterns of quantity and quality are affected by a variety of cultural, social, psychological, behavioural, pathophysiological and environmental influences. Lack of sleep exerts deleterious effects on a variety of systems with detectable changes in metabolic, endocrine and immune pathways. Over recent decades there has been growing evidence to suggest that too little sleep and too much sleep are associated with adverse health outcomes including total mortality, cardiovascular disease, type II diabetes, hypertension, respiratory disorders and obesity in both children and adults.
