Stress and the Relaxation Response: What the Evidence Says

Many people who look into hands-on therapies are really asking about stress. They want to know why their shoulders sit up around their ears, why sleep is poor, and whether anything gentle can help the body settle. This page covers what public health bodies say stress is, what physician Herbert Benson meant by the relaxation response, which relaxation methods have been studied, and how touch-based therapies are sometimes described in this context. It also says plainly what that description does and does not show. Individual situations differ, and your own doctor or qualified health professional has the final word on anything that affects your health.

What stress is and what it does in the body

The U.S. National Institute of Mental Health (NIMH) defines stress as the physical or mental response to an external cause. A stressor can be a one-time event or something that repeats over a long time. In most cases, the page says, stress goes away once the situation is resolved. That is the ordinary pattern: a deadline passes, the body calms down.

Trouble starts when the pressure does not let up. NIMH describes anxiety, the related but more persistent state, as a reaction that can continue without any immediate threat, and says anxiety that does not go away can affect sleep and the immune, digestive, cardiovascular and reproductive systems. Both stress and anxiety can bring tension, headaches or body pain, high blood pressure and lost sleep. NIMH suggests talking to a professional when stress feels unmanageable or interferes with daily life.

Researchers describe the body's quick reaction in more mechanical terms. In a review in Minnesota Medicine, Jeffery Dusek and Herbert Benson call it the stress response. They say it is an involuntary set of physiological alterations that includes higher heart rate, blood pressure and breathing rate, plus metabolic shifts that release energy. The purpose is to get energy to the muscles and heart when something demands it. The same machinery, running for weeks without a break, is what people tend to feel as being wound up.

The relaxation response in the literature

Benson, a cardiologist, used the term relaxation response for a contrasting physiological state. The same review says it can be elicited voluntarily and is associated with decreases in oxygen consumption, breathing rate and blood pressure, along with an increased sense of well-being. It also reports a slowing of the heart rate and an increase in heart rate variability (the small beat-to-beat changes in timing between heartbeats). The authors note that, when similar measures are compared, the two responses tend to move in opposite directions.

The U.S. National Center for Complementary and Integrative Health (NCCIH) uses the same idea in plain terms. Its page on relaxation techniques says they aim to produce the body's relaxation response, described as the opposite of the stress response, with slower breathing, lower blood pressure and a reduced heart rate.

One caution about wording. "Relaxation response" names a measurable pattern of changes. It does not mean that everything unpleasant in a stressful life is switched off, and the Minnesota Medicine authors themselves point out that some of the blood-based measures they discuss are affected by other factors, such as diet and polluted air.

Which relaxation approaches have evidence

NCCIH lists several approaches. Progressive muscle relaxation means tensing and then releasing muscle groups in turn. Autogenic training uses mental exercises and self-suggestion to focus on a feeling of relaxation. Guided imagery means picturing calming scenes. Biofeedback-assisted relaxation uses a device that shows how heart rate or muscle tension respond. Self-hypnosis and slow, deep breathing complete the list, and the page names meditation, yoga, tai chi and qigong as related practices that can also produce the relaxation response.

What does the evidence say? The NCCIH page describes a mixed picture. Slow breathing exercises produced a modest reduction in blood pressure. Heart rate variability biofeedback reduced self-reported stress and anxiety, and diaphragmatic breathing showed preliminary stress reduction. Relaxation helped reduce anxiety before surgery and dental anxiety. For chronic low-back pain, progressive muscle relaxation is among the non-drug options mentioned in recommendations, while benefit for fibromyalgia is described as unclear.

The limits matter as much. For sleep, the page says relaxation alone does not look especially promising, and that cognitive behavioural therapy for insomnia is the recommended first treatment. It also says safety is generally good for healthy people, but that some people report increased anxiety, intrusive thoughts or fear of losing control, and that rarely certain techniques may cause or worsen symptoms in people with epilepsy, certain psychiatric conditions, or a history of abuse or trauma. Anyone in those groups has good reason to speak with a doctor before starting.

Touch-based therapies and relaxation

Gentle hands-on approaches, including massage and the Bowen Technique, are often described as relaxing, and many people find a quiet session calming. A session is also a rare hour of lying still with someone paying attention to you, which is a lot of what relaxation techniques try to create on their own. We cannot separate those ingredients from the touch itself, and neither can most studies.

What do the better sources say? NCCIH describes massage therapy as manipulating the soft tissues of the body. It reports that breast cancer guidelines list massage among approaches that may be helpful for stress reduction, but that for people with cancer the evidence for relieving pain and anxiety is not strong, and for people with HIV/AIDS studies of anxiety are small. The page rates the quality of the evidence as low or very low in several areas. It adds that the risk of harm from massage appears low, with rare serious events reported, mostly with vigorous massage or in people at higher risk.

For the Bowen Technique in particular, none of the sources we opened for this page measures whether it produces the relaxation response, so we make no claim either way. The wider state of the research is set out in what research does and does not show for manual therapies, and the way sessions are usually run is described in what a first session involves.

Honest limits

Feeling calm after a session is a real experience, and it is also a self-reported one. A calmer mood does not show that a condition has changed, and it does not show that a particular technique caused it. Rest, attention, a warm room and expectation can all contribute. This is why researchers use control groups, and why the word "may" appears so often in the sources above.

Stress also overlaps with pain, a connection explored in pain and manual therapy. If stress is accompanied by symptoms that will not go away, such as persistent depression or anxiety, NIMH and NCCIH both point toward a health professional rather than a relaxation method alone. NCCIH's massage page also advises not to use massage to postpone seeing a health care provider about a medical problem.

The short version

Stress is a normal bodily response that becomes a problem when it does not let up. The relaxation response is the documented opposite state, and several relaxation methods have been studied with modest, uneven results. Touch-based therapies are often experienced as relaxing, but the sources we read do not show that any of them reliably changes stress-related conditions, and they do not replace advice from your own doctor.
