REM sleep

Rapid Eye Movement sleep, a sleep stage characterized by active brainwaves and vivid dreams, significant in infants for neurological development.

Stage 3 sleep

A deep sleep stage involved in growth hormone secretion and memory processes, notably decreased in elderly.

Sleep deprivation

A condition resulting from prolonged lack of sleep, leading to cognitive deficits, irritability, and increased disorientation.

Infant sleep cycles

Sleep dissatisfaction

A subjective feeling of poor sleep quality, often reported by elderly individuals despite objective measures indicating more sleep.

Sleep recovery

Influence of sleep on GPA

Research indicates that first-year college students with better sleep patterns tend to have higher GPAs.

Sleep patterns in elderly

Characterized by reduced total sleep amount and increased awakenings, often leading to complaints of insomnia.

Importance of sleep in development

Different life stages demonstrate varying amounts and types of sleep, with significant functions in early life for brain maturation.
