A recent study from the University of Chicago Medical Center demonstrates how recovery sleep can safeguard your health. Researchers found that extending sleep over two nights positively impacts well-being, potentially offsetting the effects of chronic weekday sleep loss.
For the experiment, 19 men restricted sleep to just 4.5 hours per night for four consecutive nights. They then recovered by sleeping as long as needed, averaging 9.7 hours nightly.
After the sleep restriction, participants' insulin sensitivity dropped by 23%, raising their diabetes risk by 16%. A single full recovery night normalized these metrics.
Neurologist W. Christopher Winter, M.D., involved in the study, explains: "You can make up for a lack of sleep in the short term. So if you've had a big presentation or just stayed up late, you can catch up on your lack of sleep this weekend." No more Sunday morning guilt!
