Optimum Sleep is Important for Reducing the Risk of Cardiovascular Mortality & Morbidity

Cardiovascular disease (CVD) is the leading cause of death worldwide. Humans spend up to a third of their life asleep, yet sleep problems are common in society [1]. Sleep disorders, such as insomnia and obstructive sleep apnoea, not only affect optimal functioning and productivity, but have long term impacts on health. Over the last two decades, emerging research has linked sleep duration, quality and sleep disorders with CVD, metabolic syndrome and obesity. This essay will explore the role of sleep in maintaining a healthy heart, and how strategies to improve sleep can reduce CVD risk.
