* Stress is "a force that is external in nature that causes strain upon the body, both physical and emotional."

Stress is described as a psychological and psychological and physical strain or tension generated by physical, emotional, social, economical or occupation circumstances, events, or experience that are difficult to manage or endure (Andrew M. Colman, 2015). Stress can affect all aspects of your life, which include your emotional, behaviours thinking ability, and psychical health (webmd, 2016). More than one in five Australian have reported mental health issue as a source of stress (psychology, 2014).

The definition of stress according to the Oxford dictionary is “A state of mental or emotional strain or tension resulting from adverse or demanding circumstances.”

“Stress is a state of mental or emotional strain or tension resulting from adverse or demanding circumstances”. It is generally known as “pattern of disruptive physiological and psychological reaction to events that threaten the ability to cope” (Oxford Living Dictionaries, 2017).

Stress is a nonspecific response of the human organism to any demand make upon it. It can influence the way we perform on tests and homework and how we act at home or work. There are different types of stress that can occur in the body. Acute stress is the body’s response to imminent danger. This short-term stress usually occurs when we are told we will have a quiz or have to give a speech in class. Chronic stress is a prolonged physical or emotional stress. This can cause damage to the body if the stress lasts for too long. Optimal stress is intense enough to motivate and physically prepare us to perform well but not enough to cause harm to the body.

The three types of stress are positive, normal, and negative stress. Normal stress is what we experience day to day. This type of stress is common for most people and does not have any major impact on our well being. Positive stress improves our performance and helps motivate us. Negative stress on the other hand decreases performance and can lead to both mental and physical problems.

There’s a difference between a chemical and physical prop-erties/changes. Physical properties are an aspect of matter that can be observed or measured without changing it. The Examples for Physical properties would include: color, smell, freezing point, boiling point, melting point, etc. While Chemical properies may only be observed by changing the chemical identity of a substance. An example for Chemical properties would be rusting iron.

So what is stress? Stress is a normal physical response that happens when you feel threatened or upset. When you feel that you are in danger whether it is real or imaged.

Hans Selye (1982) points out that few people define the concept of stress in the same way or even bother to attempt a clear-cut definition. According to Selye, an important aspect of stress is that a wide variety of dissimilar situations are capable of producing the stress response such as fatigue, effort, pain, fear, and even success. This has led to several definitions of stress, each of which highlights different aspects of stress. One of the most comprehensive models of stress is the Biopsychosocial Model of Stress (Bernard & Krupat, 1994). According to the Biopsychosocial Model of Stress, stress involves three components: an external component, an internal component, and the interaction between the external and internal components.
