Shift workers have a "metabolic health burden" to manage because their schedules often conflict with their need for proper sleeping and eating, and the demands of everyday living. This contributes to the tendency for shift workers to be overweight relative to their daytime counterparts. Managing wellness is a skill for shift workers to prevent illnesses like diabetes. Just because you can get by with 4 or 5 hours of sleep does not mean you require less. Talk to your doctor and seek guidance on how to get more sleep.
