Stress is the body responding to all of life demands. When your body is stressed, it releases chemicals into our blood to prepare us for these situations physically, mentally, and emotionally. Fight, flight, or freeze response is the name psychologists gave for our reaction to these reactions. There are different type of stress and the situations that causes stress are known as stressors.
Cause of stress varies for everyone. Typically cause of stress is associated with negative situations but can come from both negative and positive situations and can be cause by external factors as well as internally by yourself. Example of self-generated stress can be someone who worry excessively over something whereas external stress could be caused by politics, finances, school, work, health, pre-marriage jitters, public speaking just to name a few. Stress is different for everyone depending on the type of stressors, individual/group causing it, and even timing. Ultimately how prepared you are mentally, emotionally, and other preparation can indicate how stress you could be.

The three hormones provide our body with increased energy, help our body regulate, and increase our awareness. Stress in minor doses is fine for your body, but too much stress can negatively affect your body.
