[edit] Addiction to exercise
Physical exercise releases opioid peptides or endorphins, opiates that exhibit synergetic effects with other neurotransmitters, causing exercise euphoria, also known as "runners high",[1] and causing addiction to physical exercise and possibly decreased sex drive. This usually leads to over-exercising; a person suffering exercise addiction is often described as a "gym rat", "body nazi", "exercise freak", etc.
Stopping excessive exercise suddenly can also create a change in mood. Feelings of depression and agitation can occur when withdrawal from the natural endorphins produced by exercise occurs.

- increasing growth factors that help create new nerve cells
- increasing chemicals in the brain that help cognition[2]
