This claim is true. According to the CDC, adults (college students) should receive 7+ hours of sleep each night. Those who don't receive enough sleep could face increased risks in developing chronic conditions like obesity, diabetes, heart disease, stroke, high blood pressure, etc. Good sleep has a positive correlation with good health.
According to the National Library of Medicine, "Among college-aged students, one of the most common causes of daytime sleepiness is sleep deprivation, ie, students get inadequate sleep because they go to bed late and wake up early." College students also struggle with sleeping 7+ hours due to other factors such as alcohol, caffeine, technology, and bad sleep/hygiene habits.
