Understanding Stress
Signs, Symptoms, Causes, and
Effects
What is stress?
The Body’s Stress Response
When
you perceive a threat, your nervous system responds
by releasing a flood of stress hormones, including
adrenaline and cortisol. These hormones rouse the
body for emergency action.
Your heart pounds faster, muscles tighten, blood
pressure rises, breath quickens, and your senses
become sharper. These physical changes increase your
strength and stamina, speed your reaction time, and
enhance your focus – preparing you to either fight
or flee from the danger at hand.
Stress is a normal physical response to events that
make you feel threatened or upset your balance in some
way. 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.
The stress response also helps you rise to meet
challenges. Stress is 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.
Effects of chronic stress
The body doesn’t distinguish between physical and
psychological threats. When you’re stressed over a busy
schedule, an argument with a friend, a traffic jam, or a
mountain of bills, your body reacts just as strongly as
if you were facing a life-or-death situation. If you
have a lot of responsibilities and worries, your
emergency stress response may be “on” most of the time.
The more your body’s stress system is activated, the
easier it is to trip and the harder it is to shut off.
Long-term exposure to stress can lead to serious
health problems. Chronic stress disrupts nearly every
system in your body. It can raise blood pressure,
suppress the immune system, increase the risk of heart
attack and stroke, contribute to infertility, and speed
up the aging process. Long-term stress can even rewire
the brain, leaving you more vulnerable to anxiety and
depression.
Many health problems are caused or exacerbated
by stress, including:
- Pain of any kind
- Heart disease
- Digestive problems
- Sleep problems
|
- Depression
- Obesity
- Autoimmune diseases
- Skin conditions, such as eczema
|
How much stress is too much?
Because of the widespread damage stress can cause,
it’s important to know your own limit. But just how much
stress is “too much” differs from person to person. Some
people roll with the punches, while others crumble at
the slightest obstacle or frustration. Some people even
seem to thrive on the excitement and challenge of a
high-stress lifestyle.
Your ability to tolerate stress depends on many
factors, including the quality of your relationships,
your general outlook on life, your emotional
intelligence, and genetics.
Things that influence your stress tolerance level
- Your support network – A strong
network of supportive friends and family members is
an enormous buffer against life’s stressors. On the
flip side, the more lonely and isolated you are, the
greater your vulnerability to stress.
- Your sense of control – If you
have confidence in yourself and your ability to
influence events and persevere through challenges,
it’s easier to take stress in stride. People who are
vulnerable to stress tend to feel like things are
out of their control.
- Your attitude and outlook –
Stress-hardy people have an optimistic attitude.
They tend to embrace challenges, have a strong sense
of humor, accept that change is a part of life, and
believe in a higher power or purpose.
- Your ability to deal with your emotions.
You’re extremely vulnerable to stress if you don’t
know how to calm and soothe yourself when you’re
feeling sad, angry, or afraid. The ability to bring
your emotions into balance helps you bounce back
from adversity.
- Your knowledge and preparation –
The more you know about a stressful
situation, including how long it will last and what
to expect, the easier it is to cope. For example, if
you go into surgery with a realistic picture of what
to expect post-op, a painful recovery will be less
traumatic than if you were expecting to bounce back
immediately.
Am I in control of stress or is stress
controlling me?
- When I feel agitated, do I know how to
quickly calm and soothe myself?
- Can I easily let go of my anger?
- Can I turn to others at work to help me calm
down and feel better?
- When I come home at night, do I walk in the
door feeling alert and relaxed?
- Am I seldom distracted or moody?
- Am I able to recognize upsets that others
seem to be experiencing?
- Do I easily turn to friends or family
members for a calming influence?
- When my energy is low, do I know how to
boost it?

The situations and pressures that cause stress are known
as stressors. We usually think of stressors as
being negative, such as an exhausting work schedule or a
rocky relationship.
However, anything that puts high demands on you or forces
you to adjust can be stressful. This includes positive
events such as getting married, buying a house, going to
college, or receiving a promotion.
What causes stress depends, at least in part, on your
perception of it. Something that's stressful to you may not
faze someone else; they may even enjoy it.
For example, your morning commute may make you anxious
and tense because you worry that traffic will make you late.
Others, however, may find the trip relaxing because they
allow more than enough time and enjoy listening to music
while they drive.
Common external causes of stress
Not all stress is caused by external factors. Stress can
also be self-generated:
- Major life changes
- Work
- Relationship difficulties
|
- Financial problems
- Being too busy
- Children and family
|
Common internal causes of stress
Not all stress is caused by external factors. Stress can
also be self-generated:
- Inability to accept uncertainty
- Pessimism
- Negative self-talk
|
- Unrealistic expectations
- Perfectionism
- Lack of assertiveness
|
What's Stressful For You?
What's stressful for you may be quite different from
what's stressful to your best friend, your spouse, or
the person next door. For example:
- Some people enjoy speaking in public; others are
terrified.
- Some people are more productive under deadline
pressure; others are miserably tense.
- Some people are eager to help family and friends
through difficult times; others find it very
stressful.
- Some people feel comfortable complaining about
bad service in a restaurant; others find it so
difficult to complain that they prefer to suffer in
silence.
- Some people may feel that changes at work
represent a welcome opportunity; others worry about
whether they'll be able to cope.

Signs and symptoms of stress
overload
It’s important to learn how to recognize when your stress
levels are out of control. The most dangerous thing about
stress is how easily it can creep up on you. You get used to
it. It starts to feels familiar – even normal. You don’t
notice how much it’s affecting you, even as it takes a heavy
toll.
The signs and symptoms of stress overload can be almost
anything. Stress affects the mind, body, and behavior in
many ways, and everyone experiences stress differently.
How do you respond to stress?
Psychologist Connie Lillas uses a driving analogy to
describe the three most common ways people respond when
they’re overwhelmed by stress:
- Foot on the gas – An angry or
agitated stress response. You’re heated, keyed up,
overly emotional, and unable to sit still.
- Foot on the brake – A withdrawn or
depressed stress response. You shut down, space out, and
show very little energy or emotion.
- Foot on both – A tense and frozen
stress response. You “freeze” under pressure and can’t
do anything. You look paralyzed, but under the surface
you’re extremely agitated.
The following table lists some of the common warning
signs and symptoms of stress. The more signs and symptoms
you notice in yourself, the closer you may be to stress
overload.

If you’re experiencing any of the warning signs of stress,
it’s important to see a doctor for a full evaluation. Your
doctor can help you determine whether or not your symptoms
are stress-related.
Dealing with stress and its
symptoms
While unchecked stress is undeniably damaging, there are
many things you can do to reduce its impact and cope with
symptoms.
Learn how to manage stress
You
may feel like the stress in your life is out of your
control, but you can always control the way you respond.
Managing stress is all about taking charge: taking charge of
your thoughts, your emotions, your schedule, your
environment, and the way you deal with problems. Stress
management involves changing the stressful situation when
you can, changing your reaction when you can’t, taking care
of yourself, and making time for rest and relaxation.
Strengthen your relationships
A strong support network is your greatest protection
against stress. When you have trusted friends and family
members you know you can count on, life’s pressures don’t
seem as overwhelming. So spend time with the people you love
and don’t let your responsibilities keep you from having a
social life. If you don’t have any close relationships, or
your relationships are the source of your stress,
make it a priority to build stronger and more satisfying
connections.
Tips for reaching out and building relationships:
- Help someone else by volunteering.
- Have lunch or coffee with a co-worker.
- Call or email an old friend.
|
- Go for a walk with a workout buddy.
- Schedule a weekly dinner date
- Take a class or join a club.
|
Learn how to relax
You
can’t completely eliminate stress from your life, but you
can control how much it affects you. Relaxation techniques
such as yoga, meditation, and deep breathing activate the
body’s relaxation response, a state of restfulness that is
the opposite of the stress response. When practiced
regularly, these activities lead to a reduction in your
everyday stress levels and a boost in your feelings of joy
and serenity. They also increase your ability to stay calm
and collected under pressure.
Invest in your emotional health
Most people ignore their emotional health until there’s a
problem. But just as it requires time and energy to build or
maintain your physical health, so it is with your emotional
well-being. The more you put in to it, the stronger it will
be. People with good emotional health have an ability to
bounce back from stress and adversity. This ability is
called resilience. They remain focused, flexible, and
positive in bad times as well as good. The good news is that
there are many steps you can take to build your resilience
and your overall emotional health.
