Deep dives

Understanding Sleep Debt

Sleep debt refers to the gap between the required amount of sleep and the actual sleep received, usually highlighting that adults need seven to nine hours of sleep per night. Accumulating sleep debt can lead to various negative health indicators such as drowsiness, irritability, and trouble concentrating, reflecting a decline in both mental and physical well-being. Long-term sleep deprivation may weaken the immune system, affect appetite, and increase the risk of cardiovascular issues. Although sleep debt is not irreversible, research indicates that recovering from lost sleep can take a significant amount of time, with even an hour of missed sleep potentially requiring up to four days to recuperate fully.
