Stress — just the word may be enough to set your nerves on edge. Everyone feels stressed from time to time. Some people may cope with stress more effectively or recover from stressful events quicker than others. It's important to know your limits when it comes to stress to avoid more serious health effects.
What is stress?
Stress can be defined as the brain's response to any demand. Many things can trigger this response, including change. Changes can be positive or negative, as well as real or perceived. They may be recurring, short-term, or long-term and may include things like commuting to and from school or work every day, traveling for a yearly vacation, or moving to another home. Changes can be mild and relatively harmless, such as winning a race, watching a scary movie, or riding a rollercoaster. Some changes are major, such as marriage or divorce, serious illness, or a car accident. Other changes are extreme, such as exposure to violence, and can lead to traumatic stress reactions.
How does stress affect the body?
Not all stress is bad. All animals have a stress response, which can be life-saving in some situations. The nerve chemicals and hormones released during such stressful times, prepares the animal to face a threat or flee to safety. When you face a dangerous situation, your pulse quickens, you breathe faster, your muscles tense, your brain uses more oxygen and increases activity—all functions aimed at survival. In the short term, it can even boost the immune system.
However, with chronic stress, those same nerve chemicals that are life-saving in short bursts can suppress functions that aren't needed for immediate survival. Your immunity is lowered and your digestive, excretory, and reproductive systems stop working normally. Once the threat has passed, other body systems act to restore normal functioning. Problems occur if the stress response goes on too long, such as when the source of stress is constant, or if the response continues after the danger has subsided.
How does stress affect your overall health?
There are at least three different types of stress, all of which carry physical and mental health risks:
- Routine stress related to the pressures of work, family and other daily responsibilities.
- Stress brought about by a sudden negative change, such as losing a job, divorce, or illness.
- Traumatic stress, experienced in an event like a major accident, war, assault, or a natural disaster where one may be seriously hurt or in danger of being killed.
The body responds to each type of stress in similar ways. Different people may feel it in different ways. For example, some people experience mainly digestive symptoms, while others may have headaches, sleeplessness, depressed mood, anger and irritability. People under chronic stress are prone to more frequent and severe viral infections, such as the flu or common cold, and vaccines, such as the flu shot, are less effective for them.
Of all the types of stress, changes in health from routine stress may be hardest to notice at first. Because the source of stress tends to be more constant than in cases of acute or traumatic stress, the body gets no clear signal to return to normal functioning. Over time, continued strain on your body from routine stress may lead to serious health problems, such as heart disease, high blood pressure, diabetes, depression, anxiety disorder, and other illnesses.
How can I cope with stress?
The effects of stress tend to build up over time. Taking practical steps to maintain your health and outlook can reduce or prevent these effects. The following are some tips that may help you to cope with stress:
- Seek help from a qualified mental health care provider if you are overwhelmed, feel you cannot cope, have suicidal thoughts, or are using drugs or alcohol to cope.
- Get proper health care for existing or new health problems.
- Stay in touch with people who can provide emotional and other support. Ask for help from friends, family, and community or religious organizations to reduce stress due to work burdens or family issues, such as caring for a loved one.
- Recognize signs of your body's response to stress, such as difficulty sleeping, increased alcohol and other substance use, being easily angered, feeling depressed, and having low energy.
- Set priorities-decide what must get done and what can wait, and learn to say no to new tasks if they are putting you into overload.
- Note what you have accomplished at the end of the day, not what you have been unable to do.
- Avoid dwelling on problems. If you can't do this on your own, seek help from a qualified mental health professional who can guide you.
- Exercise regularly-just 30 minutes per day of gentle walking can help boost mood and reduce stress.
- Schedule regular times for healthy and relaxing activities.
- Explore stress coping programs, which may incorporate meditation, yoga, tai chi, or other gentle exercises.
How much do we know about relaxation techniques?
A substantial amount of research has been done on relaxation techniques. However, for many health conditions, the number or size of the studies has been small, and some studies have been of poor quality.What do we know about the effectiveness of relaxation techniques?
Relaxation techniques may be helpful in managing a variety of health conditions, including anxiety associated with illnesses or medical procedures, insomnia, labor pain, chemotherapy-induced nausea, andtemporomandibular joint dysfunction. Psychological therapies, which may include relaxation techniques, can help manage chronic headaches and other types of chronic pain in children and adolescents. Relaxation techniques have also been studied for other conditions, but either they haven't been shown to be useful, research results have been inconsistent, or the evidence is limited.What do we know about the safety of relaxation techniques?
Relaxation techniques are generally considered safe for healthy people, although there have been a few reports of negative experiences such as increased anxiety. People with serious physical or mental health problems should discuss relaxation techniques with their health care providers.What Are Relaxation Techniques?
Relaxation techniques include a number of practices such as progressive relaxation, guided imagery, biofeedback, self-hypnosis, and deep breathing exercises. The goal is similar in all: to produce the body's natural relaxation response, characterized by slower breathing, lower blood pressure, and a feeling of increased well-being.Meditation and practices that include meditation with movement, such as yogaand tai chi, can also promote relaxation.Stress management programs commonly include relaxation techniques. Relaxation techniques have also been studied to see whether they might be of value in managing various health problems.The Importance of Practice
Relaxation techniques include the following:Autogenic Training
In autogenic training, you learn to concentrate on the physical sensations of warmth, heaviness, and relaxation in different parts of your body.Biofeedback-Assisted Relaxation
Biofeedback techniques measure body functions and give you information about them so that you can learn to control them. Biofeedback-assisted relaxation uses electronic devices to teach you to produce changes in your body that are associated with relaxation, such as reduced muscle tension.Deep Breathing or Breathing Exercises
This technique involves focusing on taking slow, deep, even breaths.Guided Imagery
For this technique, people are taught to focus on pleasant images to replace negative or stressful feelings. Guided imagery may be self-directed or led by a practitioner or a recording.Progressive Relaxation
This technique, also called Jacobson relaxation or progressive muscle relaxation, involves tightening and relaxing various muscle groups. Progressive relaxation is often combined with guided imagery and breathing exercises.Self-Hypnosis
In self-hypnosis programs, people are taught to produce the relaxation response when prompted by a phrase or nonverbal cue (called a “suggestion”).What the Science Says About the Effectiveness of Relaxation Techniques
Researchers have evaluated relaxation techniques to see whether they could play a role in managing a variety of health conditions, including the following:Anxiety
Studies have shown relaxation techniques may reduce anxiety in people with ongoing health problems such as heart disease or inflammatory bowel disease, and in those who are having medical procedures such as breast biopsies or dental treatment. Relaxation techniques have also been shown to be useful for older adults with anxiety.On the other hand, relaxation techniques may not be the best way to help people with generalized anxiety disorder. Generalized anxiety disorder is a mental health condition, lasting for months or longer, in which a person is often worried or anxious about many things and finds it hard to control the anxiety. Studies indicate that long-term results are better in people with generalized anxiety disorder who receive a type of psychotherapy called cognitive-behavioral therapy than in those who are taught relaxation techniques.Asthma
There hasn't been enough research to show whether relaxation techniques can relieve asthma symptoms in either adults or children.Childbirth
Relaxation techniques such as guided imagery, progressive muscle relaxation, and breathing techniques may be useful in managing labor pain. Studies have shown that women who were taught self-hypnosis have a decreased need for pain medicine during labor. Biofeedback hasn't been shown to relieve labor pain.Depression
An evaluation of 15 studies concluded that relaxation techniques are better than no treatment in reducing symptoms of depression but are not as beneficial as psychological therapies such as cognitive-behavioral therapy.Epilepsy
There's no reliable evidence that relaxation techniques are useful in managing epilepsy.Fibromyalgia
- Studies of guided imagery for fibromyalgia have had inconsistent results.
- A 2013 evaluation of the research concluded that electromyographic (EMG) biofeedback, in which people are taught to control and reduce muscle tension, helped to reduce fibromyalgia pain, at least for short periods of time. However, EMG biofeedback didn't affect sleep problems, depression, fatigue, or health-related quality of life in people with fibromyalgia, and its long-term effects haven't been established.
Headache
- Biofeedback. Biofeedback has been studied for both tension headaches and migraines.
- An evaluation of high-quality studies concluded that there's conflicting evidence about whether biofeedback can relieve tension headaches.
- Studies have shown decreases in the frequency of migraines in people who were using biofeedback. However, it's unclear whether biofeedback is better than a placebo.
- Other Relaxation Techniques. Relaxation techniques other than biofeedback have been studied for tension headaches. An evaluation of high-quality studies found conflicting evidence on whether relaxation techniques are better than no treatment or a placebo. Some studies suggest that other relaxation techniques are less effective than biofeedback.
Heart Disease
In people with heart disease, studies have shown relaxation techniques can reduce stress and anxiety and may also have beneficial effects on physical measures such as heart rate.High Blood Pressure
Stress can lead to a short-term increase in blood pressure, and the relaxation response has been shown to reduce blood pressure on a short-term basis, allowing people to reduce their need for blood pressure medication. However, it's uncertain whether relaxation techniques can have long-term effects on high blood pressure.Insomnia
There's evidence that relaxation techniques can be helpful in managing chronic insomnia. Relaxation techniques can be combined with other strategies for getting a good night's sleep, such as maintaining a consistent sleep schedule; avoiding caffeine, alcohol, heavy meals, and strenuous exercise too close to bedtime; and sleeping in a quiet, cool, dark room.Irritable Bowel Syndrome
An evaluation of research results by the American College of Gastroenterology concluded that relaxation techniques have not been shown to help irritable bowel syndrome. However, other psychological therapies, including cognitive-behavioral therapy and hypnotherapy, are associated with overall symptom improvement in people with irritable bowel syndrome.Menopause Symptoms
Relaxation techniques have been studied for hot flashes and other symptoms associated with menopause, but the quality of the research isn't high enough to allow definite conclusions to be reached.Menstrual Cramps
Some research suggests that relaxation techniques may be beneficial for menstrual cramps, but definite conclusions can't be reached because of the small number of participants in the studies and the poor quality of some of the research.Nausea
An evaluation of the research evidence concluded that some relaxation techniques, including guided imagery and progressive muscle relaxation, are likely to be effective in relieving nausea caused by cancer chemotherapy when used in combination with anti-nausea drugs.Nightmares
Pain
Evaluations of the research evidence have found promising but not conclusive evidence that guided imagery may help relieve some musculoskeletal pain (pain involving the bones or muscles) and other types of pain.An analysis of data on hospitalized cancer patients showed that those who received integrative medicine therapies, such as guided imagery and relaxation response training, during their hospitalization had reductions in both pain and anxiety.Pain in Children and Adolescents
A 2014 evaluation of the scientific evidence found that psychological therapies, which may include relaxation techniques as well as other approaches such as cognitive-behavioral therapy, can reduce pain in children and adolescents with chronic headaches or other types of chronic pain. The evidence is particularly promising for headaches: the effect on pain may last for several months after treatment, and the therapies also help to reduce anxiety.Posttraumatic Stress Disorder
Studies of biofeedback and other relaxation techniques for posttraumatic stress disorder have had inconsistent results.Rheumatoid Arthritis
There's limited evidence that biofeedback or other relaxation techniques might be valuable additions to treatment programs for rheumatoid arthritis.Ringing in the Ears (Tinnitus)
Only a few studies have evaluated relaxation techniques for ringing in the ears. The limited evidence from these studies suggests that relaxation techniques might be useful, especially in reducing the intrusiveness of the problem.Smoking Cessation
- Limited evidence suggests that guided imagery may be a valuable tool for people who are working to quit smoking.
- In a study that compared the two techniques, autogenic training was found to be less effective than cognitive-behavioral therapy as a quit-smoking aid. However, this study involved patients in an alcohol detoxification program, so its results may not be applicable to other people.
- Preliminary research suggests that a guided relaxation routine might help reduce cigarette cravings.
Temporomandibular Joint Dysfunction
Problems with the temporomandibular joint (the joint that connects the jaw to the side of the head) can cause pain and difficulty moving the jaw. A few studies have shown that programs that include relaxation techniques may help relieve symptoms of temporomandibular joint dysfunction.What the Science Says About the Safety and Side Effects of Relaxation Techniques
- Relaxation techniques are generally considered safe for healthy people. However, occasionally, people report negative experiences such as increased anxiety, intrusive thoughts, or fear of losing control.
- There have been rare reports that certain relaxation techniques might cause or worsen symptoms in people with epilepsy or certain psychiatric conditions, or with a history of abuse or trauma. People with heart disease should talk to their health care provider before doing progressive muscle relaxation.
Who Teaches Relaxation Techniques?
A variety of professionals, including physicians, psychologists, social workers, nurses, and complementary health practitioners, may teach relaxation techniques. Also, people sometimes learn the simpler relaxation techniques on their own.
