Repaying sleep debt requires more sleep than usual. In most cases, though, sleep debt has a natural way of resolving itself because the relationship between wakefulness and sleep discourages us from becoming dangerously sleep-deprived. The natural active process the brain undergoes to ensure sleep helps to maintain natural sleep patterns even when we may overwork.
Health Consequences
Performance
Studies have shown that without enough sleep, a person’s ability to perform even simple tasks declines significantly. The average sleep-deprived individual may experience impaired performance, lack of concentration and daytime drowsiness. They are less alert and attentive and are unable to concentrate effectively.
Emotional Well-Being
Persistent sleep deprivation can cause significant mood swings, irritability, erratic behavior, hallucinations and in extremely rare cases, death. Activity in the parts of the brain that controls emotions, decision-making processes and social interactions is drastically reduced during sleep. This suggests that deep sleep may help people maintain optimal emotional and social functioning while they are awake.
Diabetes and Heart Disease
Lower rates of diabetes and heart disease are associated with adequate rest and recuperation. Studies have found that higher levels of glucose intolerance, a pre-diabetic condition, are associated with sleep deprivation.
