Hydrotherapy for Health & Wellness

 Why Hydrotherapy?

Hydrotherapy is an essential therapeutic transformational option as a modality for holistic health & wellness. From the most ancient traditions of holistic health & wellness to modern times, hydrotherapy has been an essential element of integrated and multiple approaches in the pursuit of optimal health & wellness. The following is a brief summary of ideas on hydrotherapy. A complete description of these key concepts can be found in the book, Hydrotherapy for Health & Wellness, Milady Publishing, June, 2008. 

During a hydrotherapy treatment, a therapist brings water into contact with client's body to create a therapeutic health & wellness transformation. The first step of the process is that the therapist prepares the water to be used in the treatment in various ways, including heating or cooling the water, adding products to the water, transforming the water into a shower, mist or underwater hydro-pressure or in many other ways. The water is then brought into contact with the client's body to produce a desired therapeutic transformation. All water used for hydrotherapy, as well as any other purpose, comes from some source in the hydrosphere. The following is an brief explanation of what is meant by the hydrosphere.


There is a fixed amount of water on Planet Earth, which scientist have measured to be about 332,000,000 cubic miles of water. The hydrosphere is one ancient dynamic water system, that is in a continual cycle of evaporation (purification), movement up into the atmosphere as water vapor, cooling & condensation to form clouds and eventual precipitation mainly in the form of rain & snow. Water then returns to the Earth's surface (land, lakes, ocean, ice caps), completing natural water cycle . Water will then begin to flow from higher to lower elevations, under the force of gravity, until it reaches the ocean or evaporates along the way. Even water in the frozen state as snow or ice will eventually melt or evaporate as part of this dynamic process. From the beautiful view of Earth and the hydrosphere from NASA photos, we see that the Earth's water system as one dynamic system in continual process of renewal that brings re-circulating. purifed water to all living systems (including us) on the planet. See Photos of the Hydrosphere.

In these photos, we see the beauty of this one water system that connects and unites all living systems. And the hydrosphere is comprised of many different elements, each that reveals a different expression of essence of water. In these different expressions, we see the beauty, synergy, orderliness and dynamic energy that makes water the most essential element the very matrix of life itself. And, we can experience these various dynamic expressions of water by direct interaction with them, by riding an ocean wave, bathing in a hot spring or swimming in a mountain lake. Much of the knowledge of hydrotherapy, from ancient to modern times, has come from the direct experience of the health & wellness benefits of water in natural settings. This link takes you to a presentation on the different expressions of hydrosphere on Planet Earth. 

From modern science, we learn that water has different behavioral properties that allows water to behave in a variety of ways. We see these principles of the behavior of water expressed in the dynamic behavior of water in the hydrosphere, in the complex functioning of the human body and in the how therapists use water for hydrotherapy. The following are the same dynamic basic principles in each of the above:

  • Buoyancy
  • Heat Capacity/Exchange
  • Movement (pressure): Evaporation, Gravity, Pumping (muscle contraction in living systems), Osmosis
  • Solvent (diffusion)
  • Suspension (mixing)

Hydrotherapy & the Human Body

Hydrotherapy is such a powerful transformational tool because the human body is a dynamic fluid system. The essence of hydrotherapy is that we use water to transform the behavior of water inside the human body and in doing so, we can produce therapeutic transformations at every levels of the anatomy & physiology of the human body. Water is an essential dynamic component of every element of human physiology. The following are some of the elements of the human body from the paradigm of the body as a dynamic fluid cellular system:

Human Body A&P 

  • 60% H2O (water). This means that a person that weighs 140 lbs. has 10 gallons of water (84 lbs. of water)
  • 66% of the water inside the cells (6.6 gallons), 27% (2.7 gallons) of the water is in the interstitial fluid which is the fluid matrix cells live in, 7% (.7 gallons) of water is in the blood plasma. Illustration of Human Body Fluid Elements  Link
  • The heart pumps 3,600 gallons of blood a day through a vascular system of arteries, veins and capillaries that is greater than 60,000 miles long.  Illustration of Human Body Circulation  Link
  • The main purpose of the circulatory system is bring a continual supply of nutrients and oxygen to each of the 100 trillion cells of the human body.
  • Each day, 5 gallons of blood plasma will flow through the capillaries into the interstitial fluid (to bring nutrients to the cells) and each day 4.25 gallons of interstitial fluid will flow back into the blood plasma in the capillaries and .75 gallons will flow through the lymphatic system back to the blood plasma. This allows the removal of the by-products of cell metabolism and purification of the interstitial fluid.
  • Each day, 45 gallons of blood plasma will be removed and processed by the kidneys. About 44.5 gallons will be returned to the blood plasma and about 2 quarts/liters will be removed from the body in the form of urine.
  • Each day, on average the human body naturally loses 2.5 quarts of water, mainly in the form of urine, sweat and evaporation from the skin and lungs. More will be lost if there is sweating due to the body being heated. The amount of water lost each day must be replaced to stay optimally hydrated. Every 20 days, a person will lose more than 12 gallons of water!

Water can be used in hydrotherapy to produce significant positive therapeutic changes in the A&P of the body which can produce holistic benefits to attain all health & wellness goals 

  • Increases the metabolic activity of the cells of the body. For every degree centigrade increase in the core temperature, there is a 12% increase in the metabolic activity of the cells.
  • Increase of the core temperature of the body has a stimulating influence of the immune functions of the body.
  • Circulation to cells can be increased as increased cellular metabolism increases circulation to the cells to provide more oxygen and nutrients. 
  • General circulation, including lymphatic circulation can be stimulated.
  • Improvements can be produced in vascular and cellular alignment. All cells have a natural alignment relative to every other cell in the body and no cell is more than 5 cells from a capillary (exceptions are the epidermis and cartilage disks)
  • Heating the core temperature of the body allows the body's fascial matrix, ligament, tendons and muscles to stretch with less resistance. This allows for greater alignment when using therapeutic alignment approaches.
  • Hydrotherapy treatments, when properly done, create unique and profound states of relaxation. Deep states of relaxation helps balance the autonomic nervous system, which is general over-stimulated. Greater autonomic balance can have a beneficial influence on most physiological activities of the body.

Deepest Connections with Water

Another important element of hydrotherapy is that every person has a natural connection with water and our deepest connections with water come from our first life experiences. All people are all born in the warm fluid environment of the mother's womb and our earliest memories are warmth, movement and gravity-free sensations. And once we are born, our earliest experiences are of being constantly touched and bathed in warm water while being touched. These earliest memories of being nurtured, comforted, loved are associate with our earliest experiences of different sensations of water and are naturally awakened during soothing, relaxing hydrotherapy treatments, especially when touch is involved. In the same way that are memories and associations with different smells can be enlivened with aromatherapy, our earliest water memories and associations can be enlivened by water treatments. And, water therapies can be enhanced by the addition of other sensory stimulations in the form of smells, sounds, sights and tastes. Enlivening our deepest memories of nurturing, comfort and security produce profound therapeutic benefits.

Why Hydrotherapy? Summary

 The following is a summary of some the key reasons why offering hydrotherapy treatments and programs offers such great potential to enhance a total approach to health & wellness:  

  • Hydrotherapy uses water as the essential transformation tool and these treatments include hydrotub, hydro-massage, steam, shower, misting, cryotherapy (ice), hydro-massage table & hydration. Hydrotherapy treatments are a powerful modality to help clients attain and maintain all of their health & wellness goals.
  • Hydrotherapy treatments have an continuous history of use from ancient times to modern time. Hydrotherapy has such a long and successful history because they work.
  • Scientific theory and research offers support for the use of hydrotherapy Scientific Theory & Research
  • Hydrotherapy treatments & programs can increase the number treatments and programs that can offered to your clients. The positive experiences of the treatments and the benefits can increase the number of treatments current clients are receiving, client retention and the number of new clients getting treatments.
  • Leaning the art & science of new treatment modalities is rewarding and enriching for therapists. Continuing education is not just a requirement for professional therapists, but is a natural part of a therapist's motivation to continually develop their professional skills.
  • Through education and training in hydrotherapy, we learn more about the natural universe we live in. Water, in all its beautiful expressions, is one of key elements of the Earth's dynamic natural systems. By becoming more aware and conscious of all of the expression of water, how water behaves and the nature of water as the essence of every living system, we learn more about water in Nature and increase our connection with water. From a distance, we can view the total water system of Earth as one system that unites and connects all living systems.
  • And by using water as a key element in health & wellness transformations, we become more intuitively connected with the deeper process of true healing and wellness transformations. Water is the essence of the matrix of life and and a part  natural healing transformations of the human body.
