Immediate effect of neutral underwater massage on autonomic variables among Hypertensive Patients – A Prospective randomized control trial

Hypertension, often called high blood pressure or rising blood pressure, is marked by persistently high blood pressure within the arteries. Blood is circulated from the heart to every part of the body via the vessels. With each beat, the heart pumps blood into the veins. When blood is forced against the walls of blood vessels, or arteries, by the heart, blood pressure is created. When the pressure is higher, the heart has to beat harder.

High blood pressure is another name for hypertension (HTN). It results in several health hazards, such as raising the incidence of stroke and cardiovascular disease, which can cause death.

The prevalence of hypertension has increased, especially in lower- and middle-income countries. In 2010, it was estimated that 1.39 billion people globally (31.1%) suffered from hypertension. Adults with high blood pressure had a higher probability of being in low- and middle-income nations (31.5%), where 1.04 billion people lived than in high-income countries (349 million people), where the prevalence was 28.5%.

Men had a slightly greater prevalence of hypertension (18.7%) than women (18.3%). As people age, the incidence of hypertension rises; among those over the age of 65, it was 39.2%.

The prevalence of prehypertension and hypertension is higher in South Asian individuals aged 18 to 49 in Bangladesh (35.1% and 19.8%), India (43.2 and 14.9%), Nepal (25.2% and 13.8%), and worldwide. In developing South Asian cities, the incidence of prehypertension and hypertension is higher in those with greater financial stability and education rates.

Approximately 7.5 million deaths annually, or 12.8% of all deaths globally, are related to high blood pressure. It is anticipated that 1.56 billion people will have high blood pressure in 2025. In 2014, the Eighth Joint National Committee (JNC 8) published an evidence-based guideline for the management of high BP in adults these are the guideline recommends the initiation of drug therapy to lower (SBP ≥150 mmHg) or (DBP ≥90 mmHg) at 30 to 59 years of age or older.

Risk factors include Inadequate diets (the consumption of excessive amounts of salt, having a diet rich in trans and saturated fats, and consuming minimal fruits and vegetables), being overweight or obese, a lack of physical activity, and using tobacco, smoking, and alcohol.

Risk factors that cannot be modified include age over 65, a family history of hypertension, and other diseases such as diabetes or renal disease

The concept of complementary and alternative medicine (CAM), further referred to as "integrative medicine," embraces a wide range of numerous medical and healthcare practices, products, and systems that are nowadays recognized as parts of conventional medicine. Much research has revealed that naturopathy, ayurveda, breathing exercises, yoga, meditation, diet therapy, herbal remedies, acupuncture, spiritual therapies, manipulative therapeutics, homeopathy, and some essential oils are effective complementary and alternative medicine (CAM) therapies for hypertension (HTN)

In the world of science, naturopathy is a well-known complementary and alternative medicine (CAM). It is defined as a drug-free, non-invasive, and evidence-based system of medication that grants medicines with common ingredients dependent on the vitality, toxemia, and self-healing capacity of the body, as well as the standards of healthy living.

Maintaining people’s health is the aim of naturopathy. Since it sees the human being as a holistic health unit, it addresses the body’s physiological, psychological, social (moral), and spiritual needs to improve overall health.

The naturopathic system, which is referred to in complementary and alternative medicine (CAM) as primary health care medicine, is described as a skill, science, philosophy (beliefs), and practice of diagnosis and treatment. To implement its principles, the system used natural resources. A healing force that encourages the body’s innate capacity to heal itself, gets rid of the illness’s root causes and attends to the whole body

The primary modalities used in naturopathy are hydrotherapy, which includes steam, enema, and body wraps; mud therapy; nutrition and dietetics; fasting therapy; acupuncture; acupressure; reflexology; manipulative therapy; chromotherapy; magnetotherapy; energy healing; behavioral lifestyle interventions; and chelation therapy.

One of the main treatment techniques widely used in natural medicine is hydrotherapy, sometimes known as water therapy.

Hydrotherapy is the external or internal use of water in any of its states (water, ice, or steam) to promote health or treat several illnesses with a range of temperatures, pressures, times, and places. Using water in various ways and at varying temperatures can affect various biological systems in a variety of ways.

Immersion in water of different degrees of temperature can affect the body by influencing the endocrine system, baroreceptors, thermoreceptors, sympathetic or parasympathetic nervous system, and other systems. These reactions may have an impact on the systems that regulate heart rate and water balance.

The hydrotherapeutic benefits of immersion baths, which are brought on by hydrostatic pressure, include accelerating metabolism and raising sweat while reducing muscle tension, fever, pain, and emotional repression. Neutral underwater massage is a type of hydraulic massage.

The temperature of the water is determined to be the most crucial factor in underwater massage. The buoyancy force of water and the hydrostatic pressure of the body in the underwater massage produces a decided stinging sensation at each point of contact, a powerful reflex effect is produced by stimulation of the various sets of nerves which recognize temperature, pressure, pain, and tactile impressions hence various autonomic responses are given following underwater massage of neutral and cold temperatureAlthough numerous studies have been undertaken to investigate the impact of hydrotherapy on heart rate variability, it is noteworthy that no research has been documented regarding the effect of Underwater massage on heart rate variability among hypertension Consequently, our study is going to address this research gap by examining the effects of underwater massage on heart rate variability in hypertensive individuals.
