There are multiple negative affects homework can have on a student. For example, according to a study by Stanford University, 56% of students considered homework a primary source of stress. Too much homework can result in lack of sleep, headaches, exhaustion and weight loss. Additionally excessive homework can also result in poor eating habits, with families choosing fast food as a faster alternative. Both the National Education Association (NEA) and the National PTA (NPTA) support a standard of “10 minutes of homework per grade level” and setting a general limit on after-school studying. For kids in first grade, that means 10 minutes a night, while high school seniors could get two hours of work per night. - - - Hope this helps :)
