Boynton Health Service surveyed 9,931 students at 14 different two- and four-year schools. Then they matched grade point averages with health problems such as stress, smoking and drinking as well as typical lifestyle choices such as gambling and excessive screen time. They found that students with unhealthy behaviors had significantly lower GPAs. Stress was one of the biggest factors. Of the 69.9 percent of students who reported they were stressed, 32.9 percent said that stress was hurting their academic performance.
This shows that stress can lead to lower academic achievement
