“Why Exercise” is the second in a series of posts from the Student Wellness Center.  We appreciate the expertise of the staff at the Student Wellness Center to guide our students to better health and better academic success.  Our author this week is Dr. Molly Sherrill, a resident physician in the Student Wellness Center.

In addition to its physical benefits, exercise plays a vital role in maintaining mental wellness.  People who consistently exercise sleep better at night, feel more energetic during the day, have higher self-esteem, and have better memory spans. Exercise plays an integral role in mental health.

Benefits for Mental Health

• Depression: Studies have shown that exercise can be as effective as antidepressant medication to treat mild to moderate depression. Regular exercise can also help prevent recurrent depressive episodes. How does it do this? By inducing neural growth, reducing inflammation, and releasing endorphins, the happy chemicals in your brain. Having a schedule and some quiet time to yourself every day also helps fight depression.
• Anxiety and PTSD: Exercise can be a wonderful mindfulness activity, and mindfulness is an excellent treatment for anxiety. As you work out, pay attention to all the sensations in your body and focus on the here and now, rather than on ruminating about past or future stressors. Both mindfulness and exercise relieve tension and stress.
• ADHD: Exercise increases the brain’s dopamine, norepinephrine, and serotonin levels leading to improved motivation, memory, mood, and concentration. In milder cases of ADHD, exercise may effectively replace stimulant medications.
• Addiction: As mentioned above, exercise increases dopamine, the brain’s reward chemical also released by sex, drugs, alcohol, and food. As a result, working out can aid addiction recovery by providing a healthier way to release dopamine into the brain. Additionally, exercise can be a good distraction from using and helps to reset the body’s circadian rhythm, which is often thrown out of whack by substance abuse.

Tips for Getting Started

• A little activity is better than nothing. You don’t have to become a cross-fit junkie or a marathon runner to gain the benefits of exercise. A healthy dose of exercise would be five 30-minute sessions of moderate exercise per week. If you can’t squeeze that in, a 5 minute yoga session or a walk around the neighborhood is better than no exercise at all. In fact, starting small is the smartest thing to do. If you push yourself too hard in the beginning, it will be difficult (and possibly dangerous) to maintain your new level of activity – leading to feelings of failure if you can’t follow through.
• You don’t have to make yourself miserable. If you feel like you can’t breathe, take a break. Don’t push yourself too hard. You should be able to chat comfortably with someone next to you, but aim for a slightly elevated heart rate and slightly more difficult breathing than your baseline. You should feel warm as you exercise, but you don’t necessarily need to be extremely sweaty. If you start to feel overheated, take a break and grab some water. Schedule your workout at a time of day when you feel the best. If you’re not a morning person, don’t make yourself get up at 5am for a jog. You’ll start to dread that alarm clock, and it is unlikely you will maintain the routine.  Also, choose an activity you’re likely to enjoy – dance, yoga, jogging, biking, soccer, hiking – the possibilities are vast. If you hate running, don’t run. If you hate going to the gym and lifting weights, don’t.
• Recognize obstacles you are placing for yourself. It’s easy to make excuses about why we can’t exercise today – recognize these as excuses and push through the barriers. Too tired? Good news: exercise boosts energy. Too overwhelmed? Take some time for yourself and go for a walk. In pain? Talk to your healthcare provider about safe options for your limitations, then keep in mind that movement can improve most causes of joint and muscle discomfort. Feeling hopeless about getting into shape? Remember that any little bit of exercise can help, and you have to start somewhere.
