Not getting enough sleep can raise the amount of fats floating in your blood, which might mess up how your body processes energy and makes it harder for insulin to work properly. This helps explain why a lack of rest can lead to broader health and metabolic problems.

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.

Not getting enough sleep is linked to how your body processes sugar and fat, which can raise your chances of gaining weight, developing type 2 diabetes, or getting metabolic syndrome. Basically, poor sleep messes with your body's hormone balance and heart health.

We know that not getting enough sleep is linked to problems with how your body handles sugar, but scientists still aren't exactly sure how this happens inside your body. More controlled studies are needed to figure out the exact biological steps that connect poor sleep to blood sugar issues.
