Heat to heal injuries ??

[Joseph Kissima]

hi, i've question there.

we know that cold make blood vessel to constrict (vasoconstriction) and heat do what we call vasodilatation. when we use for instance ice were aiming to reduce inflammation by restricting massive blood (bleeding) in injured tissue i.e; by doing vasoconstriction. But after 5-7 days we can use heat therapy like using of hot packs to bring nutritious blood to damaged tissue by means of vasodilatation. whats your comment?

After the initial days of cold therapy (vasoconstriction), yes, you want to increase the blood flow for more nutrients and accelerated healing. Hot packs do help and are very effective at relaxing tense muscles (which in turn helps take the strain off the injury), but this doesn't do much for the damaged tissues below the surface of the skin. This is a great write up about both hot and cold and how to use them: Heat or Ice?
