Generalised effect of cold water application on skin

  • The skin has two types of receptor:

(1)   Cold sensing receptor- for Feeling cold

(2)   Warm sensing receptor-for feeling warm

These receptors are nets of nerve tissue which develops action currents to brain. As the number of cold sensing receptors is more, so the action current developed by them is much stronger.

This action current reaches the hypothalamus.

When this cold water application is done to the skin which is warm and well supplied with blood, the cold current along with cold blood reaches the hypothalamus.

Body gears its nervous system for defence mechanism.

Body tries to stop any further cooling in the following ways:

→the skin gets tightened up to reduce the surface.

→Arterio-Venous anastomosis is closed, to reduce the blood supply.

→the blood vessels get constricted further thus reducing the blood supply.

Important points for hydrotherapy:
