Effects of Water Temperature on Cardiovascular System

Warm water temperatures (95.9°F/35.5°C) cause blood vessels to widen (vasodilation), increasing local circulation.

Cold water temperatures (below 80.6°F/27°C) cause blood vessels to narrow (vasoconstriction), decreasing local circulation.

A set of cardiovascular responses triggered when the face or body is immersed in water, leading to slower heart rate (bradycardia), narrowed peripheral blood vessels (vasoconstriction), and blood shunting to vital organs.

Hydrotherapy uses water temperature to influence blood flow and circulation within the body.

The study of how blood moves through the body, including blood pressure and volume.

The study of how water affects the cardiovascular system, including heart rate, blood pressure, and blood vessel diameter.

Hydrotherapy can be used to manage conditions by impacting blood circulation to specific areas of the body.

Hydrotherapy is a safe and effective modality, but it's important to be aware of precautions and individual health considerations.

When the whole body is submerged in water, breathing becomes harder due to increased blood flow in the chest and pressure on the chest wall, making it difficult for lungs to expand.

Immersion in water up to the neck reduces the amount of air you can exhale (expiratory reserve volume) by almost half and reduces the total volume of air you can breathe in and out (vital capacity) by 6% to 12%, ultimately increasing breathing effort.

The amount of air you can exhale after a normal breath.

The total amount of air you can breathe in and out.

The effort required to breathe is increased by 60% due to the combined effects of reduced expiratory reserve volume and vital capacity.

The movement of blood from the limbs to the chest area during water immersion.

The force exerted by the weight of water on the body during immersion.

The increased blood flow within the chest cavity during water immersion, making it harder for lungs to expand.

The upward force exerted by a fluid, such as water, that opposes gravity, reducing the weight of objects immersed in it.

The amount of effort needed to move through water, increasing with speed.

Using water's resistance to strengthen muscles and joints.

Using water's flow to assist movement, making it easier.

Therapeutic exercises and treatments performed in water.

Water therapy is typically recommended for treating conditions like arthritis, ligament injuries, and obesity.

Specific conditions or situations that make aquatic therapy unsuitable or risky for a patient.

Potential benefits of aquatic therapy, such as reduced joint stress, improved cardiovascular function, and enhanced strength.

Aquatic therapy is beneficial for patients with exercise-induced asthma, especially children, because the water environment reduces asthma symptoms while improving fitness.

Aquatic exercise is particularly helpful for older adults as it combats age-related decline, improving strength, mobility, balance, and overall quality of life.

Hydrostatic pressure and buoyancy in water provide support, making aquatic therapy beneficial for patients with balance issues.

Hydrostatic pressure in deeper water helps with circulation, making it valuable for managing cardiopulmonary conditions.

Aquatic therapy can be effective in reducing pain and improving health status for individuals with rheumatoid arthritis, though long-term benefits need further research.

Aquatic exercises show significant improvements in pain, physical functioning, stiffness, and quality of life for patients with lower limb osteoarthritis.

Aquatic exercise programs are beneficial for patients with chronic low back pain, providing relief and improving functionality.

Aquatic therapy helps athletes prepare for competitive sports by providing a safe and controlled environment to train and improve.

Aquatic therapy is a safe and beneficial option for individuals with hypersensitivity disorders, as it promotes gradual immersion and enjoyable activities to reduce sensitivity.

Exercise in water is particularly suitable for pregnant women as it reduces stress on weight-bearing joints, making it a safe and comfortable exercise option.

Bleeding in or near the treatment area is a contraindication for warm or hot water hydrotherapy as it can worsen bleeding due to increased blood flow caused by vasodilation.

Uncontrolled bowel or bladder incontinence prevents individuals from entering the pool due to the risk of contamination.

Infections present a contraindication for aquatic therapy as they pose a risk of spreading to others in the pool.

Tracheostomy, uncontrolled seizures, and severe epilepsy are contraindications for aquatic therapy due to respiratory and safety concerns.

Individuals with a vital capacity lower than 1 liter should avoid aquatic therapy immersion as it may exacerbate their respiratory symptoms.

Alcohol consumption is a contraindication for full-body water immersion due to impaired judgment and cognitive functions, increasing the risk of drowning.

Patients with indwelling catheters require proper clamping and fixation to prevent leaks or accidental removal during hydrotherapy.

Individuals with cognitive impairments may have difficulty understanding safety instructions or navigating the pool environment. Close monitoring and support are essential to prevent accidents.

Patients with tetraplegia or high paraplegia are at risk for heat prostration and hypothermia due to impaired temperature regulation. Careful monitoring of water and air temperature is crucial.

Open wounds must be covered with waterproof dressings to prevent infection and tissue damage from water exposure.

Dry skin or skin rashes may worsen with prolonged water exposure. Limit hydrotherapy time or consider using moisturizers.

Patients with impaired thermal sensation in the area to be immersed are at risk for burns from hot water. Always use a thermometer and hand to check the water temperature before immersion.

Elderly adults and infants may have impaired thermoregulation and are more susceptible to overheating or chilling during full body immersion. Limit hot or cold water hydrotherapy to small areas in these individuals.

Patients should be free from bowel and bladder accidents for at least 5 days before pool therapy to prevent contamination of the pool water.
