Cardiovascular Health Sleep

Meaning

Cardiovascular Health Sleep denotes the quality and duration of nocturnal rest that optimally supports the integrity and function of the circulatory system. Adequate sleep architecture, particularly the deeper stages of Non-REM sleep, is physiologically necessary for the parasympathetic nervous system to dominate, facilitating a natural reduction in heart rate and blood pressure. This essential period allows for endothelial repair and modulates the release of vasoactive hormones like aldosterone and renin. Insufficient or fragmented sleep is clinically recognized as a chronic stressor that elevates sympathetic tone and contributes significantly to hypertension and other cardiovascular morbidities.
