AI simplified
Abstract
Short sleep duration is associated with elevated body mass index (BMI).
- Sleep deprivation may lead to increased food intake and decreased energy expenditure.
- Changes in appetite-regulating hormones, such as leptin and ghrelin, are linked to sleep deprivation.
- Multimedia use, including television and internet, could contribute to sedentary behavior and increased caloric intake.
- Shift work and long working hours may favor weight gain due to their connection with shorter sleep durations.
- Epidemiological, biological, and behavioral evidence supports the link between sleep debt and obesity.
