Stress is your body’s way of responding to any kind of demand or threat. When you sense danger—whether it’s real or imagined—the body's defenses kick into high gear in a rapid, automatic process known as the “fight-or-flight” reaction or the "stress response."
The stress response is the body’s way of protecting you. When working properly, it helps you stay focused, energetic, and alert. In emergency situations, stress can save your life—giving you extra strength to defend yourself, for example, or spurring you to slam on the brakes to avoid an accident.
Stress can also help you rise to meet challenges. It’s what keeps you on your toes during a presentation at work, sharpens your concentration when you’re attempting the game-winning free throw, or drives you to study for an exam when you'd rather be watching TV. But beyond a certain point, stress stops being helpful and starts causing major damage to your health, your mood, your productivity, your relationships, and your quality of life.

Explanation:
When some external system of forces is applied to a body, it undergoes some deformation. This deformation may be in the form of stretching, compression, bending, or twisting. As the body undergoes deformation, it sets up some resistance to the deformation. This resistance per unit area to deformation is called stress.
Stress is defined as the force per unit area that a body is subjected to when an external system of forces acts on it. It is denoted by the symbol ‘σ’ and is measured in Pascal (Pa) or Newton per square meter (N/m²).
Stress can be further classified into three types:
1. Tensile Stress: When a body is subjected to a force that tends to stretch it, the stress developed in the body is called tensile stress.
2. Compressive Stress: When a body is subjected to a force that tends to compress it, the stress developed in the body is called compressive stress.
3. Shear Stress: When a body is subjected to a force that tends to cause deformation by sliding one part of the body over another, the stress developed in the body is called shear stress.
The formula for stress is given by:
Stress (σ) = Force (F) / Area (A)
Where, F is the force applied on the body and A is the area of the cross-section of the body.
Stress is an important parameter in the study of mechanics of materials as it helps in determining the strength and stability of a structure. It is also important in the design of structures as it helps in selecting the appropriate materials for the structure based on their strength and resistance to deformation.

Stress is a second order tensor which is defined as the internal resisting force per unit area. Stress , in real situation, is always developed when a body comes in physical or mechanical contact with its surrounding things due to strain in the body.
Stress is always developed due to strain caused by external mechanical contact forces.
Eg. Even a perfectly rigid or completely constrained body from all sides subjected to the external load or temperature change always develops some strain (may be negligible but always non zero) which results in the development of stress in the body
