The Claim

Chronic sleep deprivation is associated with reduced insulin sensitivity and impaired glucose metabolism, which may increase the long-term risk of developing metabolic disorders such as type 2 diabetes.

In plain English

Not getting enough sleep over a long period can make your body less effective at processing sugar, which might raise your chances of developing type 2 diabetes and other metabolic problems.

See the scientific wording

Sleep deprivation is consistently associated with a measurable decrease in insulin sensitivity across various experimental protocols, indicating a direct negative impact on glucose metabolism. This physiological disruption suggests that chronic insufficient rest may significantly elevate the long-term risk for developing metabolic disorders, particularly type 2 diabetes, by impairing the body's ability to regulate blood sugar effectively.

What the research says
