the link between stress and

the interactions between stress and sleep,

acute physical

A stressor is anything in the outside world that knocks you out of homeostatic balance, and the stress-response is what your body does to reestablish homeostasis.

The neural route represented by the sympathetic system is a first means by which the brain can mobilize waves of activity in response to a stressor.

If a neuron (or any cell) secretes a messenger that, instead, percolates into the bloodstream and affects events far and wide, that messenger is a hormone.

sustained psychological stress is a recent invention, mostly limited to humans and other social primates.

chronic physical

The body has a surprisingly similar set of responses (which he called the general adaptation syndrome, but which we now call the stress-response) to a broad array of stressors. If stressors go on for too long, they can make you sick.
