This Common Sleep Habit Could Be Making You Gain Weight

A Columbia University study linked about 80 minutes less sleep per night for six weeks with an average one-pound weight gain.

Participants also became more sedentary, suggesting sleep loss may reduce daily activity.

The findings point to modest but chronic sleep restriction as a possible driver of gradual weight gain.

Researchers say this could increase long-term risk for obesity, insulin resistance, heart disease, and diabetes.
