Answer: Stress can be defined as the mental and physical tension or pressure. The examples are:

• Lifting heavy objects that causes pain and discomfort.
• Increased work pressure which causes hypertension.

The three stages of stress response are:

• The alarm stage in which the response includes fight or flight. In this stage the brain send emergency signals and it is decided to face the situation or run away from it.
• The resistance stage when alarm stage doesn't decide to run away from situation, the body gets in to this stage where person gets prepared to face the stress.
• The exhaustion stage involves where the person gets exhausted with the stress and become emotionless for the results of stress.
