Heart Rate and Blood Pressure Responses to Warm Whirlpool Treatment Article

Heart Rate and Blood Pressure Responses to Warm Whirlpool Treatment - Article Example The human body in normal conditions has a temperature set point of 37 degrees Centigrade, which may get altered during the circadian rhythm, after sleep loss, during hypobaria, and subsequent to dehydration. The stability in temperature that the body maintains is achieved by maintaining a balance between the rate of heat production that occurs mainly through metabolism and rate of heat lost or gained from the environment. Normal rules of thermodynamics are involved in this transfer of heat from the body and to the body. Differences between the temperature the skin and the environment is the governing factor in the thermodynamics involved (Lloyd, 1994). The thermodynamics involved in the attempt of the body to maintain the setpoint temperature of 37 degrees Centigrade is responsible for the thermal stimulus on hemodynamics, and it is for this reason that causes Ishijima and Togawa, 1999, to maintain that bathing in hot water puts stress on the heart.  The human body in normal condit ions has a temperature set point of 37 degrees Centigrade, which may get altered during the circadian rhythm, after sleep loss, during hypobaria, and subsequent to dehydration.

The thermodynamics involved in the attempt of the body to maintain the setpoint temperature of 37 degrees Centigrade is responsible for the thermal stimulus on hemodynamics, and it is for this reason that causes Ishijima and Togawa, 1999, to maintain that bathing in hot water puts stress on the heart.   According to Press, 1991, this stress on the heart originate s from the increased pressure from the water causing vasodilation, profuse perspiration leading to a decrease in the extracellular volume of blood, increase in hematocrit levels with shortened clotting times, and an increase in the consumption of oxygen, due to the conditions of the environment saunas, spas, and hot tub baths. This raises the possibility of cardiac arrests resulting in patients during their use of saunas, spas and hot water tubs, with particular emphasis on individuals with a history of cardiovascular problems (Press, 1991). Such an understanding of the hemodynamics associated with an individual in the environmental conditions of hot tub baths, has caused physicians to warn individuals with elevated blood pressure levels and cardiac problems on the possible risks they face in hot water baths (Shin, Wilson & Wilson, 2003). Nagasawa, et al, 2001, points out that there is the risk of sudden death from hot water baths as such deaths have been associated with bathing in hot water.   This study aims to answer the question of how heart rate and blood pressure changes during a full body warm whirlpool treatment. The purpose of the study is to observe changes in the heart rate and blood pressure that occur with a warm whirlpool treatment as against the heart rate and blood pressure at rest and hypothesize the reason why certain special populations are advised precautions in the use of warm whirlpool treatments or hot tub baths. The study revolves around the hypothesis that heart rate will increase with warm whirlpool treatment and there will be a decrease in blood pressure.
