WHY BLOOD IS STOPPED WHEN ICE IS PUT ON THE CUT INJURY?

காயம் பட்ட இடத்தில் ஐஸ்

In the place of cut injury, fracture occurs in the micro vascular vessels and this is the reason for the leakage of blood. When ice is put in that place,   the blood vessels shrink.  When it shrinks, blood clots easily, the leakage is stopped.

Likewise, when head ache affects without adequate blood -circulation, blood vessels widens if you drink hot water.  By this, more blood comes to the blood vessels , head ache is cured.
