Stress is a normal response to situational pressures especially if the situation is perceived as threatening and causing harm to a person (20131 Stress. n.d.). When an individual experiences stress, hormones are released throughout the body to cause effects such as increased heart rate and blood pressure, tense muscles, and preparing to take action against the threat (20131 Stress. n.d.).
Each of the body systems plays an important role in the optimal functioning of the body, but if mental health is unwell, specifically if someone is stressed or anxious it can cause functioning in some of these systems to go array. Depending on the situation, the body will either go into ‘rest and digest’ or ‘fight or flight’. Normally, the body is in rest and digest but in a threatening or believed to
be threatening situation the body goes into fight or flight mode. Just as the name says, the body either prepares to fight the threat or flee from it (Tortora & Derrickson, 2016). When the brain recognizes a stressful situation it immediately sends information to the rest of the body through the autonomic nervous system (ANS). The ANS controls all involuntary processes, such as the heartbeat, blood pressure, and how fast blood runs through the body etc. (Harvard Health Publishing, 2011).
Depending on the situation, the body will either go into ‘rest and digest’ or ‘fight or flight’.
When the fight or flight response is triggered it immediately releases a surge of epinephrine (adrenaline) into the blood which is transported all over the body. The release of epinephrine causes many reactions including (Harvard Health Publishing, 2011):
An increase in a heartbeat to allow for faster circulation
More blood is forced to the muscles and organs to allow for immediate use
Increase in blood pressure due to more blood being forced through the vessels at a higher rate
Increase in breathing rate to allow for more oxygen uptake by the body, especially the brain to improve alertness
Triggers the release of sugar and fat from storage to be used as an energy source
These reactions may seem harmless but chronic activation of this response can impair health (Harvard Health Publishing, 2011). Epinephrine surges can damage blood vessels and arteries, leading to increased blood pressure and risks for health conditions such as heart attacks and/or strokes. This response also diminishes the ability of the body’s energy stores to replenish and contributes to the buildup of fat tissue and weight gain (Harvard Health Publishing, 2011).
Exercise has many benefits to reduce stress levels by:
Reducing the amount of cortisol (stress hormone) released in the body
Creating a distraction from daily life worries and concerns
Increasing resilience against stress (Depression and anxiety: Exercise eases symptoms, 2017)
Reducing the severity of stress (Star, 2019)
Reducing muscle tension
Improving sleep (The Mental Health Benefits of Exercise, 2019).
Exercise calms the nervous system by breaking down stress hormones and using the energy created during the fight or flight response to do work in combination with allowing the release of endorphins (feel-good hormones) to combat the stressful feelings (Soph, 2018).
Stress usually manifests negatively by emotional outbursts, such as crying or anger, but exercise can create a positive outlet as well as allowing the body to release a hormone called brain-derived neurotrophic factor (BDNF) which strengthens connections in the brain making it less susceptible to over-react to future stress (AlterG., 2017). Exercise also increases blood flow and oxygen to the brain allowing it to receive more nutrients to use as energy for sharper thinking and mental efficiency (AlterG., 2017).
Ways to Reduce Stress (Stress Management, 2019)
Take a deep breath
Lay in a dark quiet room
Yoga
Quick exercises help relieve short term stress
Ex. If you feel stress at work or after a phone call doing 10 jumping jacks can reduce the release of cortisol further reducing feelings of stress
Do longer exercise programs
This can create long term benefits for managing stress levels
Get enough sleep
Set aside leisure time for rest and relaxation, take a break from your busy schedule
Make sure to do something you love every day
Laugh!
Reduce caffeine and sugar intake
Avoid smoking
Simple Ways to Get Moving (Stress Management, 2019)
Put on your favorite music and dance
Take your pet for a walk
Park further away from the store or ride a bike instead of driving
Use the stairs more often than the elevator
Get off at an earlier bus stop and walk the rest of the way
Go for a walk with a friend
Do activities with your children/grandchildren
