A constant state of stress can affect all aspects of  students’ bodies: physical, mental, emotional, cognitive, and behavioral functions can go haywire under duress.   A critical issue concerning stress among students is its effect on learning. The Yerkes-Dodson law (1908) postulates that individuals under low and high stress learn the least and that those under moderate stress learn the most. A field study and laboratory tests support the notion that excessive stress is harmful to students’ performance.   Students react to college in a variety of ways.  For some students, college is stressful because it is an abrupt change from high school.  For others, separation from home is a source of stress. Although some stress is necessary for personal growth to occur, the amount of stress can overwhelm a student and affect the ability to cope.
