Students who are into their sports and who play competitively no doubt have a cutting edge over others in terms of physical health which likely translates into better mental health, but they also have the added pressure of additional commitments.
Students have a lot to juggle. At no other time in life is a person expected to complete full days of study, as well as up to 30 hours of work every week, and maintain household and familial/social relationships. It is an extraordinary expectation! Some students thrive on the pace and pressure while others struggle, turn to counselors or professional services for help and sadly others just pack it in and quit; only 54% of university entrants in the U.S. come out with a graduate degree.
