On average, most college students get 6-6.9 hours of sleep per night, and the college years are notoriously sleep-deprived due to an overload of activities. An insufficient number of hours of sleep per night may not only impact our moods and health but also GPA. As college students we all have been accustomed to dealing with not going to sleep until the wee hours of the morning, but studies have proven that this does more harm than good. Lack of sleep can lead to a weakened immune system, increases weight gain and obesity, mental health issues, as well as the extremely important decreased academic performance. So even though it may seem like a smarter idea to stay up late getting some late minute cramming in, the simple solution to study better and more efficiently is to get between 6 and 8 hours of sleep a night. I promise you that your body and your grades will thank you for it later.
