In experiments, researchers monitored three groups of participants who slept 4, 6, or 8 hours a night over an extended amount of time. After just two weeks, the group who slept 6 hours had a similar reaction time as a person whose blood alcohol concentration was 0.1 percent. Those who slept 4 hours would fall asleep during their cognitive tests. People who consistently sleep less than 7 to 8 hours a night may suffer cognitive issues.
