College students are among the most sleep-deprived people in the country. This may be due to the irregularity of their sleeping habits. According to a 2001 study, only 11% of college students have good sleep quality, and 73% have occasional sleep problems. This same study found that 18% of college men and 30% of college women reported suffering from insomnia within the past 3 months, and over half reported feeling sleepy during the morning.
