In the fall, due to the end of daylight saving time, people gain an hour of sleep. This extra hour can have positive effects on health, including metabolic regulation and weight management. Research has shown that sleep loss may be a risk factor for obesity and type 2 diabetes. Lack of sleep is linked to reduced immune function, metabolic dysregulation, weight gain, and a greater risk of falls and accidents. Recovering from lost sleep is important, and it can take up to four days to recover from one hour of lost sleep and up to nine days to completely eliminate sleep debt. Additionally, extending bedtime for short sleepers may prevent weight gain or facilitate weight loss. Lack of sleep can hinder weight loss efforts or contribute to weight gain through its impact on hormones. Therefore, gaining an extra hour of sleep in the fall can have positive effects on overall health and well-being.
