Stress

 

 

What is stress? Stress can be defined as a state of worry or mental tension caused by a difficult situation. Stress is a natural human response that prompts us to address challenges and threats in our lives.

Stress responses help your body adjust to new situations. Stress can be positive, keeping us alert, motivated and ready to avoid danger. For example, if you have an important test coming up, a stress response might help your body work harder and stay awake longer. But stress becomes a problem when stressors continue without relief or periods of relaxation.

Considerations

Stress is a normal feeling. There are two main types of stress:

• Acute stress. This is short-term stress that goes away quickly. You feel it when you slam on the brakes, have a fight with your partner, or ski down a steep slope. It helps you manage dangerous situations. It also occurs when you do something new or exciting. All people have acute stress at one time or another.
• Chronic stress. This is stress that lasts for a longer period of time. You may have chronic stress if you have money problems, an unhappy marriage, or trouble at work. Any type of stress that goes on for weeks or months is chronic stress. You can become so used to chronic stress that you don't realize it is a problem. If you don't find ways to manage stress it may lead to health problems.

 

SIGNS OF TOO MUCH STRESS

Stress can cause many types of physical and emotional symptoms. Sometimes, you may not realize these symptoms are caused by stress. Here are some signs that stress may be affecting you:

• Diarrhea or constipation
• Forgetfulness
• Frequent aches and pains
• Headaches
• Lack of energy or focus
• Sexual problems
• Stiff jaw or neck
• Tiredness
• Trouble sleeping or sleeping too much
• Upset stomach
• Use of alcohol or drugs to relax
• Weight loss or gain

 

Causes

People react differently to stressful situations. What is stressful for one person may not be stressful for another, and almost any event can potentially cause stress. For some people, just thinking about a trigger or several smaller triggers can cause stress.

There is no identifiable reason why one person may feel less stressed than another when facing the same stressor. Mental health conditions, such as depression, or a building sense of frustration, injustice, and   anxiety can make some people feel stressed more easily than others.

Previous experiences may affect how a person reacts to stressors.

Common major life events that can trigger stress include:

• job issues or retirement
• lack of time or money
• bereavement
• family problems
• illness
• moving home
• relationships, marriage, and divorce

Other commonly reported causes of stress are:

• abortion or pregnancy loss
• driving in heavy traffic or fear of an accident
• fear of crime or problems with neighbors
• pregnancy and becoming a parent
• excessive noise, overcrowding, and pollution
• uncertainty or waiting for an important outcome

Some people experience ongoing stress after a traumatic event, such as an accident or some kind of abuse. Doctors will diagnose this as PTSD.

Those who work in stressful jobs, such as the military or the emergency services, will have a debriefing session following a major incident, and occupational healthcare services will monitor them for PTSD.

Stress effects on the body

Stress affects all systems of the body including the

 musculoskeletal, respiratory,

cardiovascular, endocrine, gastrointestinal, nervous,

and reproductive systems.

 

Respiratory system 

The respiratory system supplies oxygen to cells and removes carbon dioxide waste from the body. Air comes in through the nose and goes through the larynx in the throat, down through the trachea, and into the lungs through the bronchi. The bronchioles then transfer oxygen to red blood cells for circulation.

Stress and strong emotions can present with respiratory symptoms, such as shortness of breath and rapid breathing, as the airway between the nose and the lungs constricts. For people without respiratory disease, this is generally not a problem as the body can manage the additional work to breathe comfortably, but psychological stressors can exacerbate breathing problems for people with pre-existing respiratory diseases such as asthma and chronic obstructive pulmonary disease (COPD; includes emphysema and chronic bronchitis).

Some studies show that an acute stress—such as the death of a loved one—can actually trigger asthma attacks. In addition, the rapid breathing—or hyperventilation—caused by stress can bring on a panic attack in someone prone to panic attacks.

Working with a psychologist to develop relaxation, breathing, and other cognitive behavioral strategies can help.

 

Nervous system 

The nervous system has several divisions: the central division involving the brain and spinal cord and the peripheral division consisting of the autonomic and somatic nervous systems.

The autonomic nervous system has a direct role in physical response to stress and is divided into the sympathetic nervous system (SNS), and the parasympathetic nervous system (PNS). When the body is stressed, the SNS contributes to what is known as the “fight or flight” response. The body shifts its energy resources toward fighting off a life threat, or fleeing from an enemy.

The SNS signals the adrenal glands to release hormones called adrenalin (epinephrine) and cortisol. These hormones, together with direct actions of autonomic nerves, cause the heart to beat faster, respiration rate to increase, blood vessels in the arms and legs to dilate, digestive process to change and glucose levels (sugar energy) in the bloodstream to increase to deal with the emergency.

The SNS response is fairly sudden in order to prepare the body to respond to an emergency situation or acute stress—short term stressors. Once the crisis is over, the body usually returns to the pre-emergency, unstressed state. This recovery is facilitated by the PNS, which generally has opposing effects to the SNS. But PNS over-activity can also contribute to stress reactions, for example, by promoting bronchoconstriction (e.g., in asthma) or exaggerated vasodilation and compromised blood circulation.

Both the SNS and the PNS have powerful interactions with the immune system, which can also modulate stress reactions. The central nervous system is particularly important in triggering stress responses, as it regulates the autonomic nervous system and plays a central role in interpreting contexts as potentially threatening.

Chronic stress, experiencing stressors over a prolonged period of time, can result in a long-term drain on the body. As the autonomic nervous system continues to trigger physical reactions, it causes a wear-and-tear on the body. It’s not so much what chronic stress does to the nervous system, but what continuous activation of the nervous system does to other bodily systems that become problematic.

 

 

 

How is stress diagnosed?

Stress is subjective — not measurable with tests. Only the person experiencing it can determine whether it's present and how severe it feels. A healthcare provider may use questionnaires to understand your stress and how it affects your life.

If you have chronic stress, your healthcare provider can evaluate symptoms that result from stress. For example, high blood pressure can be diagnosed and treated.

What are some strategies for stress relief?

You can’t avoid stress, but you can stop it from becoming overwhelming by practicing some daily strategies:

• Exercise when you feel symptoms of stress coming on. Even a short walk can boost your mood.
• At the end of each day, take a moment to think about what you’ve accomplished — not what you didn’t get done.
• Set goals for your day, week and month. Narrowing your view will help you feel more in control of the moment and long-term tasks.
• Consider talking to a therapist or your healthcare provider about your worries.

Meditate

During meditation, you focus your attention and quiet the stream of jumbled thoughts that may be crowding your mind and causing stress. Meditation can instill a sense of calm, peace and balance that can benefit both your emotional well-being and your overall health.

Guided meditation, guided imagery, visualization and other forms of meditation can be practiced anywhere at any time, whether you're out for a walk, riding the bus to work or waiting at the doctor's office. You can also try deep breathing anywhere.

Laugh more

A good sense of humor can't cure all ailments, but it can help you feel better, even if you have to force a fake laugh through your grumpiness. When you laugh, it not only lightens your mental load but also causes positive physical changes in your body. Laughter fires up and then cools down your stress response. So read some jokes, tell some jokes, watch a comedy or hang out with your funny friends. Or give laughter yoga a try.

Connect with others

When you're stressed and irritable, your instinct may be to isolate yourself. Instead, reach out to family and friends and make social connections.

Social contact is a good stress reliever because it can offer distraction, provide support and help you tolerate life's up and downs. So take a coffee break with a friend, email a relative or visit your place of worship.

Got more time? Consider volunteering for a charitable group and help yourself while helping others.

Assert yourself

You might want to do it all, but you can't, at least not without paying a price. Learning to say no or being willing to delegate can help you manage your to-do list and your stress.

Saying yes may seem like an easy way to keep the peace, prevent conflicts and get the job done right. But it may actually cause you internal conflict because your needs and those of your family come second, which can lead to stress, anger, resentment and even the desire to exact revenge. And that's not a very calm and peaceful reaction.

Get enough sleep

Stress can cause you to have trouble falling asleep. When you have too much to do — and too much to think about — your sleep can suffer. But sleep is the time when your brain and body recharge.

And the quality and amount of sleep you get can affect your mood, energy level, concentration and overall functioning. If you have sleep troubles, make sure that you have a quiet, relaxing bedtime routine, listen to soothing music, put clocks away, and stick to a consistent schedule.

Keep a journal

Writing down your thoughts and feelings can be a good release for otherwise pent-up emotions. Don't think about what to write — just let it happen. Write whatever comes to mind. No one else needs to read it, so don't strive for perfection in grammar or spelling.

Just let your thoughts flow on paper — or computer screen. Once you're done, you can toss out what you wrote or save it to reflect on later.

Get musical and be creative

Listening to or playing music is a good stress reliever because it can provide a mental distraction, reduce muscle tension and decrease stress hormones. Crank up the volume and let your mind be absorbed by the music.

If music isn't one of your interests, turn your attention to another hobby you enjoy, such as gardening, sewing, sketching — anything that requires you to focus on what you're doing rather than what you think you should be doing.

Seek counseling

If new stressors are challenging your ability to cope or if self-care measures just aren't relieving your stress, you may need to look for reinforcements in the form of therapy or counseling. Therapy also may be a good idea if you feel overwhelmed or trapped, if you worry excessively, or if you have trouble carrying out daily routines or meeting responsibilities at work, home or school.

Professional counselors or therapists can help you identify sources of your stress and learn new coping tools.
