IT'S ALL IN YOUR HEAD:

Here's some not-so-great data on antidepressants:

Only 60% of patients respond positively to antidepressants.

Antidepressants can help people improve 9.6 points on a depression scale, but a placebo can help them improve 7.8 points.

People with depression actually don't have less serotonin than people without depression.

That's not to say SSRIs don't work, only that, according to some data, they're about 25% more effective than a Skittle. (Not to mention, they can induce long-term side effects like weight gain or sexual dysfunction.)

Looking to bridge this treatment gap, researchers have started looking into other options for relief. And somewhat surprisingly, exercise has emerged as a capable alternative.
