Stress may be considered as any physical, chemical, or emotional factor that causes bodily or mental unrest and that may be a factor in causing disease. Physical and chemical factors that can cause stress include trauma, infections, toxins, illnesses, and injuries of any sort.

Sustained or chronic stress, in particular, leads to elevated hormones such as cortisol, the stress hormone, and reduced serotonin and other neurotransmitters in the brain, including dopamine, which has been linked to depression.
