Stress, whether physiological, biological or psychological, is an organism's response to a stressor such as an environmental condition. Stress is the body's method of reacting to a condition such as a threat, challenge or physical and psychological barrier. There are two hormones that an individual produces during a stressful situation, well known as adrenaline and cortisol. There are two kinds of stress hormone levels. Resting (basal) cortisol levels are normal everyday quantities that are essential for standard functioning. Reactive cortisol levels are increases in cortisol in response to stressors. Stimuli that alter an organism's environment are responded to by multiple systems in the body. In humans and most mammals, the autonomic nervous system and hypothalamic-pituitary-adrenal (HPA) axis are the two major systems that respond to stress.
Stress management consists of a wide spectrum of techniques and psychotherapies aimed at controlling a person's level of stress, especially chronic stress, usually for the purpose of improving everyday functioning. Stress produces numerous physical and mental symptoms which vary according to each individual's situational factors. These can include a decline in physical health, such as headaches, chest pain, fatigue, and sleep problems, as well as depression. The process of stress management is named as one of the keys to a happy and successful life in modern society. Life often delivers numerous demands that can be difficult to handle, but stress management provides a number of ways to manage anxiety and maintain overall well-being.
Autogenic training is a relaxation technique first published by the German psychiatrist Johannes Heinrich Schultz in 1932. The technique involves repetitions of a set of visualisations accompanied by vocal suggestions that induce a state of relaxation and is based on passive concentration of bodily perceptions like heaviness and warmth of limbs, which are facilitated by self-suggestions. Autogenic training is used to alleviate many stress-induced psychosomatic disorders.
Functional gastrointestinal disorders (FGID), also known as disorders of gut–brain interaction, include a number of separate idiopathic disorders which affect different parts of the gastrointestinal tract and involve visceral hypersensitivity and motility disturbances.
Yoga nidra or yogic sleep in modern usage is a state of consciousness between waking and sleeping, typically induced by a guided meditation.
A relaxation technique is any method, process, procedure, or activity that helps a person to relax; attain a state of increased calmness; or otherwise reduce levels of pain, anxiety, stress or anger. Relaxation techniques are often employed as one element of a wider stress management program and can decrease muscle tension, lower blood pressure, and slow heart and breath rates, among other health benefits.
Systematic desensitization, or graduated exposure therapy, is a behavior therapy developed by the psychiatrist Joseph Wolpe. It is used when a phobia or anxiety disorder is maintained by classical conditioning. It shares the same elements of both cognitive-behavioral therapy and applied behavior analysis. When used in applied behavior analysis, it is based on radical behaviorism as it incorporates counterconditioning principles. These include meditation and breathing. From the cognitive psychology perspective, cognitions and feelings precede behavior, so it initially uses cognitive restructuring.
Yoga as therapy is the use of yoga as exercise, consisting mainly of postures called asanas, as a gentle form of exercise and relaxation applied specifically with the intention of improving health. This form of yoga is widely practised in classes, and may involve meditation, imagery, breath work (pranayama) and calming music as well as postural yoga.
Progressive muscle relaxation (PMR) is a method of deep muscle relaxation that does not involve any medications, meaning it is a non-pharmacological intervention. The idea behind progressive muscle relaxation is that there is a relationship between a person's mind and body. The body responds to its environment by creating certain mind or body states such as anxiety, stress, and fear. When the body is in these states, the muscles tense up. Progressive muscle relaxation aims to reverse these body states back to more neutral, relaxed states.
Conscious breathing encompasses techniques directing awareness toward the breathing process, serving purposes from improving respiration to building mindfulness. In martial arts like tai chi and qigong, breathing exercises are said to strengthen diaphragm muscles and protect organs, with reverse breathing being a common method. Meditation traditions, including yoga and Buddhist meditation, emphasize breath control. Yoga's pranayama is believed by practitioners to elevate life energies, while Buddhist vipassanā uses anapanasati for mindfulness of breathing.
Cardiac yoga is a system of stress management and health promotion designed specifically to focus on the needs of a heart patient. Cardiac yoga is basically artery gentle yoga exercises tailored to the special needs of people who have various cardiac problems, live with a cardiac condition or recover from cardiac diseases. Cardiac yoga allows for the participant to stay seated while learning the different movements, and eventually working their way up to a full yoga routine.
The psychological and physiological effects of meditation have been studied. In recent years, studies of meditation have increasingly involved the use of modern instruments, such as fMRI and EEG, which are able to observe brain physiology and neural activity in living subjects, either during the act of meditation itself or before and after meditation. Correlations can thus be established between meditative practices and brain structure or function.
Stress-related disorders constitute a category of mental disorders. They are maladaptive, biological and psychological responses to short- or long-term exposures to physical or emotional stressors. The National Institute of Environmental Health Sciences categorizes Obsessive-Compulsive Disorder (OCD) and Post-Traumatic Stress Disorder (PTSD) as stress-related disorders. However, the World Health Organization's ICD-11 excludes OCD but categorizes PTSD, Complex Post-Traumatic Stress Disorder (CPTSD), adjustment disorder as stress-related disorders.
Chronic stress is the physiological or psychological response induced by a long-term internal or external stressor. The stressor, either physically present or recollected, will produce the same effect and trigger a chronic stress response. There is a wide range of chronic stressors, but most entail relatively prolonged problems, conflicts and threats that people encounter on a daily basis. And several chronic stressors, including "neighbourhood environment, financial strain, interpersonal stress, work stress and caregiving.", have been identified as associated with disease and mortality.
Chronic headache, or chronic daily headache (CDH), is classified as experiencing fifteen or more days with a headache per month. It is estimated that chronic headaches affect "4% to 5% of the general population". Chronic headaches consist of different sub-groups, primarily categorized as chronic tension-type headaches and chronic migraine headaches. The treatments for chronic headache are vast and varied. Medicinal and non-medicinal methods exist to help patients cope with chronic headache, because chronic headaches cannot be cured. Whether pharmacological or not, treatment plans are often created on an individual basis. Multiple sources recommend multimodal treatment, which is a combination of medicinal and non-medicinal remedies. Some treatments are controversial and are still being tested for effectiveness. Suggested treatments for chronic headaches include medication, physical therapy, acupuncture, relaxation training, and biofeedback. In addition, dietary alteration and behavioral therapy or psychological therapy are other possible treatments for chronic headaches.
In psychology, relaxation is the emotional state of low tension, in which there is an absence of arousal, particularly from negative sources such as anger, anxiety, or fear.
Mindfulness-based stress reduction (MBSR) is an eight-week evidence-based program that offers secular, intensive mindfulness training to assist people with stress, anxiety, depression and pain. Developed at the University of Massachusetts Medical Center in the 1970s by Professor Jon Kabat-Zinn, MBSR uses a combination of mindfulness meditation, body awareness, yoga and exploration of patterns of behavior, thinking, feeling and action. Mindfulness can be understood as the non-judgmental acceptance and investigation of present experience, including body sensations, internal mental states, thoughts, emotions, impulses and memories, in order to reduce suffering or distress and to increase well-being. Mindfulness meditation is a method by which attention skills are cultivated, emotional regulation is developed, and rumination and worry are significantly reduced. During the past decades, mindfulness meditation has been the subject of more controlled clinical research, which suggests its potential beneficial effects for mental health, athletic performance, as well as physical health. While MBSR has its roots in wisdom teachings of Zen Buddhism, Hatha Yoga, Vipassana and Advaita Vedanta, the program itself is secular. The MBSR program is described in detail in Kabat-Zinn's 1990 book Full Catastrophe Living.

Trauma-sensitive yoga is yoga as exercise, adapted from 2002 onwards for work with individuals affected by psychological trauma. Its goal is to help trauma survivors to develop a greater sense of mind-body connection, to ease their physiological experiences of trauma, to gain a greater sense of ownership over their bodies, and to augment their overall well-being. However, a 2019 systematic review found that the studies to date were not sufficiently robustly designed to provide strong evidence of yoga's effectiveness as a therapy; it called for further research.
The science of yoga is the scientific basis of modern yoga as physical exercise in human sciences such as anatomy, physiology, and psychology. Yoga's effects are to some extent shared with other forms of exercise, though it differs in the amount of stretching involved, and because of its frequent use of long holds and relaxation, in its ability to reduce stress. Yoga is here treated separately from meditation, which has effects of its own, though yoga and meditation are combined in some schools of yoga.
