What is Hydrotherapy and What are the Benefits


What is Hydrotherapy? 

Hydrotherapy, also known as aquatic therapy, is a therapeutic practice that leverages the physical properties of water for pain relief and treatment.  This treatment often involves performing specific exercises in warm water, for example in a pool or hot tub.


Hydrotherapy is rooted in historical practices observed in ancient civilizations like the Egyptians, Greeks, and Romans, who acknowledged and utilised water for its healing benefits. Today, these benefits are not just historical observations but are validated by scientific evidence.


It's important to note that hydrotherapy should be performed under the guidance of a qualified healthcare professional who can assess your individual needs and tailor the treatment accordingly.



What can hydrotherapy be used for?

  • Arthritis
  • Joint Replacements
  • Fractures
  • Spinal Decompression
  • Chronic Diseases
  • Post-Surgery Rehabilitation
  • Pain Alleviation
  • Mobility Enhancement
  • Balance and Coordination Improvement
  • Cardiovascular Fitness
  • Mental Health Improvement


Alleviation of Pain

Hydrotherapy can be particularly beneficial for managing joint pain, thanks to several key mechanisms:


Hydrotherapy utilises the principle of buoyancy to alleviate pain. When a person is submerged in water, the gravitational force on the body is reduced, lessening the weight placed on painful joints or injured areas. This reduction in weight allows easier movement, making it especially beneficial for conditions such as arthritis, injuries, or during post-surgery rehabilitation.

Hydrostatic Pressure

Being in water exerts a hydrostatic pressure on the body, which can aid in reducing swelling and improving blood circulation. Enhanced circulation can expedite the healing process, potentially minimising pain.

Thermal Effect

Many forms of hydrotherapy use warm water to soothe sore muscles, promote relaxation, and improve circulation. These processes can help the body remove waste products that can accumulate during periods of muscle tension or spasms, leading to pain relief.

Strength Training

Water provides a resistance that allows gentle strengthening exercises(link to hot tub exercise piece when live) without heavy weights. Strengthening the muscles around painful joints can improve stability, decrease strain, and consequently lessen pain over time.


Sensory Stimulation

According to the pain gate theory, the gentle pressure and warmth from water can stimulate sensory receptors in the skin, potentially blocking pain signals from reaching the brain.

Stress Reduction

The soothing nature of warm water can reduce stress levels, which often influence the perception of pain. High stress and tension can exacerbate pain, so therapies that promote relaxation can also aid in pain relief.

Ease of Movement and improved mobility

The buoyancy of water can make movements easier and less painful, particularly beneficial for individuals with arthritis, obesity, or recovering from orthopaedic surgery. Hydrotherapy allows these individuals to perform exercises that might be difficult or impossible to do on land.

Postoperative Rehabilitation

Hydrotherapy is often used in the postoperative phase of orthopaedic surgeries like joint replacements, spinal surgeries, or fractures. The buoyancy of water allows early mobilisation and accelerates the rehabilitation process.


Chronic Disease Management

Hydrotherapy can help manage symptoms of chronic conditions like arthritis, fibromyalgia, chronic fatigue syndrome, etc. It can decrease joint pain and stiffness, improve strength, and enhance overall function.

Spinal Decompression

For people with spinal problems, the buoyancy provided by water can help decompress the spine, providing relief from pain.

What are the different types of hydrotherapy?

In modern practice, hydrotherapy encompasses a wide range of techniques and treatments, including:

Hydrothermal therapy 

This involves the use of both hot and cold water to stimulate the body's natural healing processes. It can include techniques such as hot and cold showers, saunas, steam baths, swim spas, and hot tubs.

Water exercises

Water-based exercises are performed in a pool, swim spa or other water environment. The buoyancy of water reduces the impact on joints, making it an effective therapy for rehabilitation, improving strength and flexibility, and managing certain conditions such as arthritis. Water based exercises 

Whirlpool baths 

These baths, like Hydropoo’ls serenity hot tubs, use jets of water to create a swirling motion, providing a massage-like effect on the body. They can help relieve muscle tension, promote relaxation, and improve circulation.

Contrast hydrotherapy: 

This involves alternating between hot and cold water treatments to improve blood circulation, reduce inflammation, and promote overall healing. It may involve immersing a particular body part in hot and cold water or using hot and cold compresses

Hydro massage

Hydro massage involves the use of high-pressure jets of water directed at specific areas of the body. It can help relax muscles, reduce pain, and improve circulation.


Conditions Possibly Making Hydrotherapy Unsuitable

  • Infectious Diseases
  • Cardiovascular Conditions
  • Severe Kidney Diseases
  • Open Wounds or Severe Skin Conditions
  • Serious Lung Conditions
  • Incontinence
  • Fever or Acute Illness
  • Certain Types of Cancer
  • High-Risk Pregnancy

Infectious Diseases 

People with contagious diseases, particularly those that can be spread through water, should avoid hydrotherapy to prevent the spread of the infection.

Cardiovascular Problems

People with heart conditions, especially uncontrolled high blood pressure or heart failure, should consult their doctor before starting hydrotherapy as the hydrostatic pressure can put additional strain on the heart.

Kidney Disease

People with severe kidney diseases may need to avoid hydrotherapy due to potential difficulties in regulating electrolytes and fluid balance.

Open Wounds or Skin Infections 

Open wounds, skin infections, or conditions like severe eczema or psoriasis may worsen with exposure to water or chemicals used in the water.

Serious Lung Conditions

People with serious lung conditions may have difficulty with the increased pressure on the chest that comes from immersion in water.


For hygiene reasons, individuals with incontinence might be advised to avoid hydrotherapy.

Fever or Acute Illness

If someone has a high fever or acute illness, the use of hot water in hydrotherapy can increase body temperature even further, which may be harmful.

Certain Types of Cancer

Individuals with certain types of cancer, particularly those with compromised immune systems due to chemotherapy, might be advised to avoid hydrotherapy to reduce the risk of infections.


While some forms of hydrotherapy can be beneficial during pregnancy, others may not be recommended, particularly in high-risk pregnancies. It's always advisable for pregnant women to consult with their doctor before starting any new form of therapy.



How can you begin Hydrotherapy

Here are some general steps to help you get started on your hydrotherapy journey::

Step 1: Consult with a Healthcare Professional

Before you begin hydrotherapy, consult with a doctor or a physical therapist. They will evaluate your condition and determine if hydrotherapy is the right treatment for you.

Is Hydrotherapy different from aqua aerobics?


Unlike aqua-aerobics, which are often high-intensity, hydrotherapy is centred on gentle, controlled movements and relaxation techniques. Its primary aim is to alleviate discomfort and improve physical function.
