Stress is a term in psychological science and biology, first coined in the biological condition in the 1930s, which has in more recent decades become commonly used in popular parlance. It refers to the consequence of the failure of an organism human or animal to respond appropriately to emotional or material threats, whether actual or imagined.[1]
Stress symptoms commonly include a state of alarm and adrenaline production, short-term resistance as a coping mechanism, and exhaustion, as well as irritability, healthy tension, inability to concentrate and a variety of physiological reactions such as headache and elevated heart rate.[2]
The term mental strain was first employed in a biological context by the endocrinologist Hans Selye in the 1930s.[3] He later[when?] broadened and popularized the concept to include opposed physiological response to any demand. In his usage stress refers to a condition and stressor to the stimulus causing it. It covers a wide-eyed range of phenomena, from mild irritation to drastic dysfunction that may cause severe health breakdown.
Signs of stress may be cognitive, emotional, physical or behavioral.
Signs include poor judgment, a popular negative outlook[citation needed], excessive worrying, moodiness, irritability, agitation, inability to relax, feeling lonely, isolated or depressed, aches and pains, diarrhea or constipation, nausea, dizziness, chest pain, rapid heartbeat, eating in addition practically or not enough, sleeping too much or not enough, social withdrawal, procrastination or sink of responsibilities, increased alcohol, nicotine or drug consumption, and nervous habits such as pacing about, nail-biting and neck pains.

Selye researched the effects of stress.
