The Claim
In adults with overweight or obesity and insulin resistance, a 5.5-week sleep extension intervention that increases total sleep time by 1.1 hours per night has no effect on whole-body, hepatic, or adipose tissue insulin sensitivity as measured by hyperinsulinemic-euglycemic clamp with tracer infusions, and does not reduce 24-hour plasma glucose or insulin area under the curve.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Extending sleep by 1.1 hours per night for 5.5 weeks in adults with overweight, obesity, and insulin resistance does not improve how the body uses insulin in muscle, liver, or fat tissue, and does not lower average blood glucose or insulin levels over 24 hours.
See the scientific wording
In adults with overweight or obesity and insulin resistance, a 5.5-week sleep extension intervention that increases total sleep time by 1.1 hours per night does not improve whole-body, hepatic, or adipose tissue insulin sensitivity as measured by hyperinsulinemic-euglycemic clamp with tracer infusions, nor does it reduce 24-hour plasma glucose or insulin area under the curve.
Adding extra sleep does not change how the body's liver, fat, and muscle cells respond to insulin, so blood sugar and insulin levels stay the same.
What the research says
1 studyScientists gave overweight, sleep-deprived adults an extra hour of sleep each night for six weeks and found that their body’s ability to use insulin didn’t get better, and their blood sugar and insulin levels stayed the same.
