Showering?

Okay, this is a weird one to me.  To reduce depression, take a cold shower.  Really.  It's backed up by research, found here.   Here's an excerpt:    Exposure to cold is known to activate the sympathetic nervous system and increase the blood level of beta-endorphin and noradrenaline and to increase synaptic release of noradrenaline in the brain as well. Additionally, due to the high density of cold receptors in the skin, a cold shower is expected to send an overwhelming amount of electrical impulses from peripheral nerve endings to the brain, which could result in an anti-depressive effect.
