Exercise boosts your mood, whether you’re healthy, clinically depressed or chronically ill.
Movement heals.
Depression can make you sedentary, and being sedentary—watching TV, driving, using a computer—can make you depressed, yet movement heals.
Exercise increases blood flow to the brain, boosts neurogenesis, releases endorphins and BDNF—it’s basically your body’s very own antidepressant.
It may be the last thing you feel like doing, but it should be the first thing you schedule in your day.
Long-term, prospective studies show that the more you move, the less likely you are to be depressed (Teychenne, 2008) or to develop burnout (Lindwall, 2014).
Overall, the best scientific evidence proves that exercise boosts your mood whether you’re healthy, clinically depressed, or chronically ill. In one randomized trial in 946 depressed outpatients, exercise outperformed the usual care for depression (Hallgren, 2015).
When it comes to prevention, physically active people have a 45 percent lower chance of developing depression.
What works in terms of exercise?
▪Moderate exercise seems to be best—such as walking on a treadmill or outdoors—at about 64 to 76 percent of maximal heart rate for thirty minutes. (Maximal heart rate is 220 beats per minute minus your age.)
▪BDNF seems to rise the most in response to exercise in women who are not currently taking antidepressant medications and those who have greater pre-exercise depression.
▪Another study in women only shows that exercise of any intensity helps with a depressed mood.
▪For new moms, light- to moderate-intensity aerobic exercise improves mild to moderate depressive symptoms.
▪The optimal frequency isn’t as well defined, but five days per week is recommended.
👉Invest now: high levels of physical activity in middle age predict a lower chance of depression twenty-five years later.
