It may seem like a minor adjustment, but some people struggle with fatigue, irritability, and brain fog in the days following the transition. For others — especially night owls — the adjustment period can last for weeks.Circadian rhythms govern many physiological processes in plants, animals and even bacteria, highlighting life’s remarkable sensitivity to changes in environmental conditions.
