A study conducted by Columbia University Irving Medical Center reveals that losing just 80 minutes of sleep nightly over six weeks can lead to measurable weight gain and increased sedentary behavior.Researchers observed 95 adults who reduced their sleep by 90 minutes each night, tracking changes in weight, physical activity, and hormonal markers.

Participants gained an average of one pound and spent 17 additional minutes daily in inactivity, with men and postmenopausal women showing even greater declines.

The findings highlight that chronic mild sleep loss, common among 30% of adults, may contribute to obesity-related risks like diabetes and heart disease.

Unlike extreme sleep deprivation studies, this research mirrors real-world sleep patterns, suggesting that even minor sleep reductions could lead to clinically significant weight gain over time.

The study underscores the importance of adequate sleep in preventing metabolic disorders and emphasizes the need for further research on sleep restoration strategies for those with chronic sleep insufficiency.
