Neurologist Explains Cognitive Effects of Sleeping Six Hours Nightly for Two Weeks

Dr. Sudhir Kumar, a neurologist at Apollo Hospitals in Hyderabad, explains that consistently sleeping six hours per night for two weeks significantly impairs cognitive functions. Studies show this sleep restriction reduces attention span, disrupts prefrontal cortex activity, and slows reaction times to levels comparable to staying awake for 24-48 hours. Despite these effects, individuals often feel they are functioning normally, which poses risks to memory, learning, and decision-making.
