ANYONE CAN EXPERIENCE a bout of the blues from time to time, but clinical depression can be long-lasting and debilitating. Symptoms include a change in appetite, loss of energy, and feelings of helplessness; and those who suffer from depression often experience significant anxiety as well.
But one route to recovery may start with some running shoes: Consistent exercise can join the ranks with other treatments for depression and anxiety, helping to boost mood, combat feelings of gloom, and prepare the brain to better handle stress [1] [2].
Battling blues – What’s the deal?
Health professionals give regular exercise a gold star for helping prevent disease, keeping off excess weight, and even spicing up that sex life. Another benefit is that different types of physical activity, from aerobic exercise to qigong, can help lessen depressive symptoms [3] [4]. One study found walking and jogging a few times a week was generally as effective as antidepressants in reducing symptoms of depression [5]. But it’s not only aerobic workouts that do the trick— researchers found depressed elderly people who trained at high intensities several times weekly saw improvement in their quality of life and sleep [6]. (Extra credit for older folks hitting the weight room, too!)
Besides increasing levels of feel-good endorphins, scientists suggest physical activity may work like some antidepressant drugs to alter brain chemistry[7] [8]. Recent research (albeit on mice) found that those who voluntarily ran on wheels had greater amounts of the brain cells that produce the neurotransmitter GABA (associated with feelings of calm) than those who just sat in their cages [2]. When all the rodents were placed in ice-cold water, the runners’ brains released more of that GABA, meaning they likely felt less anxious in the stressful situation.
Moreover, staying in shape can also help us gain confidence and distract us from worries. And research suggests this effect isn’t just temporary: In patients diagnosed with clinical depression, exercise may not only relieve sad symptoms, but could also help diminish symptoms for good. Some psychologists even advocate that mental health professionals prescribe physical activity to treat anxiety and depression the same way they would recommend medication.
Sweat away sadness – The debate
Gearing up for a workout is rarely a bad idea. But while exercise may help reduce depression and anxiety once they’ve become an issue, so far, research hasn’t proven that a few laps around the track will prevent the blues from arriving in the first place. One study failed to find evidence that exercise could reduce the risk of depression in vulnerable populations. Other research suggests exercise improves depressive symptoms only moderately [10].
Plus, exercise may not help treat depression the same way across the board: According to one study, light exercise helps depressed women slightly more than it helps men [11]. And when it comes to anxiety, some scientists say exercise works best in conjunction with medication [12].
In March, singer-songwriter Bressie spoke to John Murray on RTÉ Radio 1, saying that he had found exercise helped him gain control over panic attacks and depression – but noted that while it worked for him, it might not be the answer for everyone.
Still, it’s especially important to make physical activity a priority when feeling down, since research suggests people who are depressed are less likely to exercise. A therapist can help create an individual treatment plan for depression that might include some exercise. Along with eating well, getting enough sleep, and spending time with family and friends, getting a move on for 30 minutes a day, three to five days a week, can help keep that smile around.
