What is the difference between moist and dry heat therapy and why is moist heat considered more effective?

Question:

Answers:
The difference is that moist heat does not dehydrate the tissue.
For example: a conventional electric heating pad heats your tissues by creating an intense heat though electrical wires, which over time will dehydrate your tissues.
Using a moist hot compress can be more effective to relax tired/stiff muscle tissue, without drying you out, because water can absorb and communicate large quantities of heat (physics - property of specific heat).
Also, your body needs the hydration to maintain healthy tissue. Always drink plenty of water regardless of the type of heat you use to keep you properly hydrated. And if there's any inflamation, I suggest not using heat at all, as this can further inflame the tissue. use ice.

moist heat is like a hot,wet towel or a hot water bottle or a hot tub soak. It makes the muscles and joints less likely to be stiff.

Dry heat is produced by heating elements like burners,electric bulbs,heating coils and most important the sun all are due to infra-red emission,if strong enough can cause damage to the skin, like sun tan if the skin exposed for longer periods can cause sun burns and blisters, so it should be well controlled for the therapeutic purposes. In contrasts the moist heat add the effect of water vapor or Even hot or warm water to the therapeutic modality to sooth the treated area an also help in opening the sweat pores and increase the the efficiency of the circulation through the treated region which is beneficial and less damaging effects.
