Stress can make the individual more susceptible to physical illnesses like the common cold.[38][need quotation to verify] Stressful events, such as job changes, correlate with insomnia, impaired sleeping, and health complaints.[39] Research indicates the type of stressor (whether it is acute or chronic) and individual characteristics such as age and physical well-being before the onset of the stressor can combine to determine the effect of stress on an individual.[40] An individual's personality characteristics (such as level of neuroticism),[15] genetics, and childhood experiences with major stressors and traumas[16] may also dictate their response to stressors.[40] ./cache/en-wikipedia-org-7027.html ./txt/en-wikipedia-org-7027.txt
