With today’s fast paced lifestyles, 24*7 activity and an increasing screen-time at night, sleep disorders are widespread. Indians are not getting enough sleep in both urban as well as rural India. Sleep loss and related disorders are a silent epidemic affecting adults as well as children. The objective of the current study was to investigate the overall impact of hours of sleep and sleep quality on the cognitive alertness of the research scholars and the Psychomotor vigilance Test (PVT) was used to measure the cognitive alertness. The final results of the study show that even though the research scholars are getting the required amount of sleep, their cognitive alertness is still affected and they are indeed suffering from sleepiness.
