As there are many causes of depression it's probably a bit much to say that there are no hacks. There are plenty of lifestyle changes that will possibly have a positive effect - exercise, diet and sleep being three obvious ones. Even if they don't lift depression they are going to be beneficial to health.

I cut out refined sugar from my diet and started taking turmeric in the form of golden paste (as a natural cure for tendinitis) a couple f months back. I noticed an improvement in my mood and outlook as a pleasant side effect.
