Sleep is an essential physiological process necessary for maintaining physical health, mental well-being, cognitive functions, and overall quality of life. Disturbances in sleep cycles and inadequate sleep duration have become increasingly common because of changing lifestyles, stress, and technological influences. The present study entitled “Assessment of the Sleep Cycle Effect on Human Health” was conducted to evaluate the relationship between sleep patterns and various health parameters among different age groups. A total of 100 participants from different age groups were selected and categorized into adolescents, young adults, middle-aged adults, and older adults. Information regarding sleep duration, sleep quality, stress level, fatigue level, and concentration ability was collected using questionnaires and health surveys. The findings indicated that sleep duration significantly affected stress level, cognitive performance, and physical health conditions. Young adults showed lower sleep duration (6.5 ± 0.5 h/day) compared with adolescents (7.8 ± 0.6 h/day). Individuals sleeping less than five hours exhibited higher stress scores (85%) and lower concentration levels (45%) compared with individuals sleeping more than seven hours. The study concludes that adequate sleep duration and healthy sleep habits are essential for maintaining physical and psychological well-being. Proper sleep management may reduce risks associated with chronic health conditions and improve overall quality of life.
