Roughly half of college students will have some degree of depression at some point during their time in school. Even more startling 6. 2 percent of college students surveyed in 2012 considered suicide and 1.3 percent attempted it, according to an American College Health Association study released this spring. If you’re feeling depressed on campus, you may find the following tips helpful.

Exercise: Physical activity releases endorphins—chemicals that produce an overall positive feeling within the body, which fight depression naturally. Mental health experts claim that exercise is a solution to those feeling mild or moderate depression. However, for those severely depressed, simply doing sports is not enough.

Use school counseling services: Campuses don’t employ mental health experts simply to throw thousands of dollars down the drain. Their job is to help students, so experts recommend you use them. Most students, however, are hesitant to take a trip to their college’s counseling center, fearing being laughed at by peers. As a result, some schools like Texas Christian University, are testing students for mental health problems when they get sick and visit the campus health clinic.

Take advantage of technology: Staying in touch with family members and friends from childhood and high school has become easier than ever with the coming of Facebook and video chat services like Skype. While mental health experts insist that it’s important to make friends in your new environment and be involved in the college community, it’s also significant to keep in touch with the people you knew before college.

Go to sleep: Following a fairly regular sleep pattern can defend you against depression. In college, many students’ sleep patterns are irregular thanks to late-night studying and partying, which is harmful to their mental health. Research strongly suggests that sleep is the key to learning and memory formation.
