Hormonal

Sleep deprivation and short sleep duration independently increase the risk of insulin resistance, glucose intolerance, and obesity.

Aim for 7-9 hours of sleep per night. Chronic sleep restriction (<6 hours) impairs your body's ability to process glucose and increases hunger hormones, making weight management and diabetes prevention significantly harder.

GoodSupportsHIGH confidence
Sleep deprivation has been shown to raise blood pressure... and evidence has recently emerged that sleep curtailment may be associated with glucose intolerance and insulin resistance, independent of obesity per se.
