Hydrotherapy - Reduce Stress and Relax

Hydrotherapy is supposed to alleviate body tension, muscle soreness and joint stiffness and instill a sense of calm. Here's what the science says.

Before engaging in any complementary medical technique, you should be aware that many of these techniques have not been evaluated in scientific studies. Often, only limited information is available about their safety and effectiveness. Each state and each discipline has its own rules about whether practitioners are required to be professionally licensed. If you plan to visit a practitioner, it is recommended that you choose one who is licensed by a recognized national organization and who abides by the organization's standards. It is always best to speak with your primary health care provider before starting any new therapeutic technique.

Background

Hydrotherapy (also called balneotherapy) involves the use of water in any form or at any temperature (steam, liquid, ice) for the purpose of healing. Water has been used medicinally for thousands of years by many cultures, including ancient China, Japan, India, Rome, Greece, the Americas and the Middle East. Modern hydrotherapy can be traced to the development of "water cure" spas in 19th century Europe.

Today, a wide variety of water-related therapies are used:

  • Immersion in a bath or body of water (for example, the ocean or a pool)
  • Placement of wet towels (hot or cold) over the skin
  • Douches with watering cans or hoses
  • Water birth
  • Arm and foot baths
  • Rising-temperature hip baths
  • Sitz baths (soaking in hot or cold water below the hips)
  • Steam baths or saunas
  • Rubbings with cold, wet towels
  • Spa-, hot tub-, whirlpool- or motion-based hydrotherapy
  • Purifying mineral baths with additives such as sea salt or essential oils
  • Dead Sea water treatments

 


Some therapies include the use of water as only one aspect of the technique:

  • Nasal irrigation
  • Colonic irrigation or enema
  • Physical therapy in pools (Physical therapy or exercise in water makes use of the ability to float and resistance of water against motion.)
  • Drinking of mineral water or "enriched" water
  • Steam inhalation or humidifiers
  • Coffee infusions
  • Aromatherapy or baths with added essential oils
  • Water yoga
  • Water massage (including Watsu, a form of bodywork conducted in pools)

Theory

Various theories have been proposed to explain how hydrotherapy works, depending on the specific technique used. Some hydrotherapy practitioners and textbooks suggest that water treatments and wraps may detoxify the blood, stimulate blood circulation, enhance the immune system and improve digestion. Scientific research is limited in these areas.

Some theories are based on the observation that applying warmth to the skin causes vasodilation (expansion of blood vessels), which brings blood to the body's surface. Warmth can also cause muscle relaxation. Cold temperatures have the opposite effect.


Evidence

Scientists have studied hydrotherapy for the following uses:

Low back pain
Several small studies in humans report that regular use of hot whirlpool baths with massaging jets reduces the duration and severity of back pain when used with standard medical care. Additional research is needed to make a strong conclusion.

Anorectal lesions (hemorrhoids, anal fissures)
There is early evidence that sitz baths may help relieve symptoms of anorectal conditions, although research is not definitive. Sitz baths are often available in hospitals.

Skin bacteria
There is not enough research to determine if hydrotherapy reduces bacteria on the skin, or if hydrotherapy offers any benefit.

Knee rehabilitation
Limited research is available. Further study is needed to make a conclusion. td>

Labial edema during pregnancy
Limited research is available. Further studies are needed.

Fibromyalgia
Research results are mixed. Further well-designed trials are needed to make a recommendation.

Heart failure
Study results are mixed in this area. For example, one randomized controlled trial suggests repeated sauna treatment may reduce the risk of arrhythmias. Another randomized trial suggests this therapy may improve heart failure-related symptoms and heart rate response to exercise. However, some studies report no benefits. Further well-designed research is needed before firm conclusions can be drawn.

Arthritis
Hydrotherapy is traditionally used to treat symptoms of rheumatoid arthritis and osteoarthritis. There is evidence that hydrotherapy may reduce pain and increase functional activity. Several studies have been published, but because of design flaws, the benefits remain unclear.

Atopic dermatitis
Research is limited, and no clear conclusions can be drawn.

Burns
Research is limited, and no clear conclusions can be drawn.


 


Chronic obstructive pulmonary disease (COPD)
It is not clear if deep breathing exercises in heated pools are beneficial in people with COPD. There is evidence that suggests water training may improve overall physical fitness, but additional research is needed to confirm these results.

Chronic venous insufficiency
Hydrotherapy is used in Europe for chronic venous insufficiency, a syndrome that may include leg swelling, varicose veins, leg pain, itching and skin ulcers. A few studies report benefits of leg stimulation with cold water alone, or in combination with warm water. However, this research is only preliminary, and additional study is necessary to make a firm conclusion.

Common cold
Research is limited, and no clear conclusions can be drawn.

Diabetes mellitus
Research is limited, and no clear conclusions can be drawn.

Claudication (painful legs from clogged arteries)
Research is limited, and no clear conclusions can be drawn.

High cholesterol
One randomized controlled trial suggests that repeated sauna therapy may protect against oxidative stress, which leads to the prevention of atherosclerosis. Further research is needed before firm conclusions can be made.

Insomnia
Preliminary study of hydrotherapy for insomnia shows inconclusive results.

Labor, childbirth
There is preliminary research examining whether giving birth in water reduces labor pain, the duration of labor, perineal damage to the mother and birth complications. However, this research is not reliable enough to form clear conclusions about safety or benefits.

Pain
Hydrotherapy has been studied for various types of pain, with inconclusive results.

Pelvic inflammatory disease
Research is limited, and no clear conclusions can be drawn.

Pressure ulcers, wound care
Research is limited, and no clear conclusions can be drawn.

Psoriasis
Evidence regarding hydrotherapy for psoriasis is varied. There is not enough research available to make a recommendation.

Spinal muscular atrophy
There is not enough research available to make a recommendation.

Varicose veins
There is not enough research available to make a recommendation.

Bone density in menopause
There is preliminary evidence suggesting that aquatic exercises, like other forms of weight-bearing exercises, may help increase bone mass.


Unproven Uses

Hydrotherapy has been suggested for many uses, based on tradition or on scientific theories. However, these uses have not been thoroughly studied in humans, and there is limited scientific evidence about safety or effectiveness. Some of these suggested uses are for conditions that are potentially life-threatening. Consult with a health care provider before using hydrotherapy for any use.

Potential Dangers

The safety of some hydrotherapy techniques is not well studied.

Sudden or prolonged exposure to extreme temperatures in baths, wraps, saunas or other types of hydrotherapy should be avoided, particularly by patients with heart disease or lung disease or by pregnant women. Warm temperatures can lead to dehydration or low blood sodium levels, and hydration and electrolyte intake should be maintained. Cold temperatures may worsen symptoms in people with circulatory disorders, such as acrocyanosis, chilblains, erythrocyanosis or Raynaud's disease.

 


Water temperature should be carefully monitored, particularly for patients with temperature-sensitivity disorders, such as neuropathy. People with implanted medical devices such as pacemakers, defibrillators or liver infusion pumps should avoid high temperatures or therapies that involve electrical currents.

Contact with contaminants or additives in water (such as essential oils or chlorine) can irritate the skin. Skin infections may occur if water is not sanitary, particularly in patients with open wounds. There are several reported cases of dermatitis and bacterial skin infections after hot tub or whirlpool use.

People with fractures, blood clots, bleeding disorders, severe osteoporosis or open wounds and pregnant women should avoid vigorous therapy with water jets in. Although water births are popular, safety is not well studied. The effects of prolonged labor in hot or cold water are not known.

Hydrotherapy should not delay the time it takes to see a health care provider for diagnosis or treatment with more proven techniques or therapies. And hydrotherapy should not be used as the sole approach to illness. Consult with your primary health care provider before starting hydrotherapy.

Summary

There are many hydrotherapy techniques used for a wide variety of health conditions. Early evidence suggests that regular use of hot whirlpool baths with massaging jets improves the duration and severity of low back pain. Additional research is necessary to make a strong recommendation. There is no conclusive evidence for any other condition.

Prolonged treatments, particularly in extreme temperatures, should be avoided. Skin irritation or bacterial infections may result from additives or contaminants in the water. People with fractures, blood clots, bleeding disorders, severe osteoporosis or open wounds and pregnant women should avoid vigorous therapy with water jets. Although water births are popular, safety has not been well studied. Hydrotherapy should not be used as the sole approach to any illness. Consult with your primary health care provider before starting hydrotherapy.
