How Does Stress
Affect Health






How does stress affect health? Stress can affect a person's physical, emotional and mental health adversely in many ways.

It is estimated that 90% of diseases are caused by stress. If we can get a handle on the stress that affects our lives, we might be able to live longer, healthier, happier lives.

Merriam-Webster defines stress as: "a physical, chemical, or emotional factor that causes bodily or mental tension and may be a factor in disease causation; a state resulting from a stress: one of bodily or mental tension resulting from factors that tend to alter an existant equilibrium".

Stress can be a positive force that keeps us alert, ready to avoid or handle danger or meet deadlines. It can also enhance our emotional intelligence and creative capabilities.

Stress can come from your external environment, your inner thoughts and your body itself.

During a 'fight or flight' instance, the body releases stress hormones to allow a burst of strength and endurance.

Your heart speeds up, your breathing quickens, your muscles tense, digestion stops, and blood flow to your muscles and brain increase up to 400%.

When you are under stress, the 'fight or flight' hormones still flood your system, and after repeated instances, this reaction can harm your physical, mental and emotional health.

Stress is known to build up and when symptoms start to surface, it's the body's way of getting our attention to do something about it.
