Stress & the student body

The adrenal glands produce “fight or flight” hormones. In some situations (e.g., when a tornado is heading your way) these can potentially save your life. These hormones get your body mobilized for action in order to survive (dodge that tornado).

In other situations (e.g., exam nerves) they are not so helpful—more of an overreaction. Your body doesn’t use that extra jolt of energy. Instead of earning tornado survival bragging rights, you’re at risk for the negative side effects of extended stress.

Epinephrine (adrenaline), a hormone, enters your bloodstream and circulates through your body. Here’s what it does:

• Your heart beats faster
• Your blood pressure rises
• Your muscles tense
• Your sweat production increases
• You may feel over-alert and struggle to fall asleep or stay asleep
• You may feel mentally foggy and unable to function and focus in the daytime

Cortisol, a hormone, gets your body mobilized and ready for action in order to survive. But in many cases (e.g., exam prep) this cortisol is not so useful. Elevated cortisol levels for an extended period of time can:

• Impair your memory and learning (and your exam performance)
• Impair your immune function
• Erode your bone density
• Cause digestion problems
• Contribute to weight gain
• Raise your blood pressure

The amygdala, a part of the brain that is key to emotional processing, sends a distress signal to the hypothalamus.

The hypothalamus, a part of the brain that regulates hormones and controls body functions, relays that distress signal via the autonomic nervous system. This manages involuntary body functions such as breathing and blood pressure.

Deep breathing & mindfulness reduce your stress hormones

Deep abdominal breathing engages the vagus nerve, which signals to slow down the heart rate, lower the blood pressure, and put the brakes on cortisol.

+ Deep breathing techniques

“If I ever get too stressed, I will try to take a moment, even if only a minute, to close my eyes, slow my breathing down, and consciously relax my muscles. It is a good way to ‘reset,’ I find.”
—Carson G., second-year graduate student, Portland State University, Oregon

Mindfulness & meditation are powerful tools for reducing stress hormones and boosting emotional resilience in demanding situations.

Set aside 10–15 minutes a day. Focus on taking deep breaths and recognizing which areas of your body are holding tension. For regular tips and guidance, see Mind your mind, a monthly series on our BetterU pages.

+ Mindfulness for college students

“Practicing mindfulness has helped me develop a greater consciousness of myself and what is around me. When I pay more attention to my thoughts and surroundings, I am better able to focus on the task at hand without stressing out.”
—Saira K., second-year student, Collin College, Texas

Physical activity manages your stress hormones

Physical activity channels cortisol productively.

Cardio workouts and competitive sports will do the job.

Low-intensity activities (e.g., tai chi and yoga) work too:

Fluid movement + deep breathing + mental focus = calm

“Exercise helps clear your head and makes it easier to sit and stay focused mentally. Choose whatever activity you love. It doesn’t have to be training for a triathlon or an hours-long workout. It can be going for a walk, playing Dance Central, or shooting hoops.”
—Dr. Laura Offutt, creator of Real Talk with Dr. Offutt, an interactive health website for teens

Student stories 
“I personally use exercise as a de-stressor! You’ll find me more at the gym during exam time.”
—John Handal, fourth-year undergraduate, Redeemer University College, Ontario

“Jogging alone while listening to music at night can really calm you down too.”
—Reza Wang-Lotfi, second-year undergraduate, New Jersey Institute of Technology

Laughter, joy, music, & downtime raise your feel-good hormones

Laughter and joy channel cortisol productively.

• They release endorphins (your brain’s feel-good chemicals)
• They are associated with lower levels of stress hormones

Making time for fun could actually improve your exam score. On weekends, make time to go to a funny movie or a live comedy show with friends. Even the anticipation of a good joke can start to lower stress hormones, according to a 2008 study in the Journal of the Federation of American Societies for Experimental Biology.

Music is uplifting. You knew this anyway, but a 2003 study in Neuroendocrinology Letters showed that listening to music lowers cortisol and stress levels.

Taking an hour before bed without cramming lets your brain and body slow down. If you get antsy, try reading (no textbooks!).

Student stories
“When I am overwhelmed I like to turn off my critical mind and just play music for a while to relax.”
—Sam C., third-year student, Ohlone College, California

“I take walks with my son and have conversations with him. A five-year-old can have you laughing in minutes, easing the stress.”
—Latasha C., fourth-year student taking online classes, Park University, Missouri

“People who are successful at reducing the negative effects of stress have a variety of tried-and-true techniques. This helps keep their techniques effective over time, and covers different environments and situations,” says Steve Lux, senior health educator at Northern Illinois University.

Your personal “black bag” can include strategies that are effective indoors or out, any time of the year, at no cost, and that address either your physical or emotional needs (or both).

Sample black bag

• Mindfulness
• Support group (e.g., Al-Anon)
• Guided relaxation 
• Nature or neighborhood walk
• Call friend or therapist
• Church or temple
• Music (e.g., Mozart’s Sonata for Two Pianos in D Major)
