Sleep deprivation increases the risk of cardiometabolic diseases (hypertension, type 2 diabetes, obesity) by promoting systemic inflammation, insulin resistance, and sympathetic nervous system overactivity.
Aim for 7-8 hours of sleep to protect your heart and metabolic health. Chronic sleep restriction (<6 hours) significantly increases your risk of obesity, type 2 diabetes, and hypertension by promoting inflammation and insulin resistance. Prioritizing sleep is a foundational strategy for preventing cardiometabolic disease.
StrongSupportsVERY_HIGH confidence
Sleep deprivation increases the risk for obesity (about 55% higher risk), insulin resistance, T2DM (28% higher risk), and hypertension (21% higher risk)... experimental sleep deprivation (acute or chronic) is accompanied by increased sympathetic outflow, with consequent higher blood pressure and heart rate.
Why this rating
Supported by robust prospective epidemiological data, experimental studies, and clear mechanistic pathways.

- Sleep deprivation (defined as <6-7 hours/night or acute/chronic restriction) increases the risk of infectious diseases by impairing innate and adaptive immune responses, including reduced T-cell efficacy and antibody production.Good
- Sleep deprivation accelerates the progression of neurodegenerative diseases, particularly Alzheimer's, by impairing the glymphatic clearance of beta-amyloid (Aβ) and increasing neuroinflammation.Good
- Sleep deprivation increases the risk of cancer development and progression by suppressing anti-tumor immune responses, specifically reducing Natural Killer (NK) cell activity and CD8+ T-cell numbers.Moderate
