Paraffin bath is another form of conductive heating. Paraffin baths are
particularly useful for contractures due to rheumatoid arthritis, burns, and
progressive systemic sclerosis (scleroderma). Paraffin usually is applied to the
hands, arms, and feet. Paraffin wax is melted and mixed with liquid paraffin.
For therapeutic use, the paraffin bath is maintained at the melting point of
51.7-54.4°C in a thermostatically controlled insulated container. The 2
application methods include:
(1) the dip method
(2) immersion.
The dip method
The hand or foot is placed in the liquid paraffin bath and withdrawn when a
thin layer of warm solid paraffin forms, becomes adherent, and covers the skin.
The dipping procedure is repeated until a thick paraffin glove is formed. The
heat can be retained by wrapping with towels for a period of 20 minutes; then,
the cool solid paraffin glove is peeled away and the paraffin is recycled. The
dip method is a mild heat application because only a limited amount of heat is
available for transfer to the skin.
Immersion
Alternatively, the body part is immersed in the paraffin bath for 20-30
minutes. The immersion method transfers heat not only from the solid paraffin
block but also from the liquid paraffin bath itself. The heat transfer rate from
the liquid paraffin bath to the skin is slowed as the solid paraffin glove
provides a poor thermal conductor. This modality represents a vigorous heat
application, causing a significant increase in skin tissue temperature, up to
46°C, with a marked temperature decrease in the subcutaneous tissue. Water at
the same temperature applied by the same method would be intolerable because of
the high specific heat and thermal conductivity.
Paraffin Wax Bath - Why and How they work
Since 1962, physicians,
physical therapists, and arthritis specialists have recommended the TherabathPRO
Paraffin Therapy Bath because warm paraffin therapy is one of the most effective
methods of delivering heat to aching joints.
But do you know how it
works?
Paraffin wax has a very
high heat capacity, meaning it is able to absorb and retain a great amount of
heat. A paraffin wax spa takes advantage of paraffin's heat-retaining capacity
in a simple process called heat transfer. In technical terms, heat is
transferred to the core of the affected area as paraffin goes through a phase
change. As it melts, the paraffin becomes a liquid and is able to retain more
heat. Then, when a hand, foot, or other area is dipped into the heated bath, the
phase of the paraffin that surrounds the dipped area quickly changes into a
solid. The heat that is given off is called the heat of fusion.
More simply, the heat that
goes into melting the paraffin comes out when it solidifies into a comforting
paraffin coating, thus transferring the heat into the affected limb. Another way
to look at it is the paraffin is the medium that transfers heat from the
TherabathPRO to the painful area.
At the same time, the heat
from the paraffin opens pores and increases circulation in the skin. This is why
paraffin is so beneficial to skin, leaving skin softened and more radiant.
Paraffin therapy is one of
the most effective methods of applying deep heat to relieve pain and stiffness.
The warm paraffin also moisturizes for healthier looking, softer skin
