The cooling effect of sweating occurs because of the breaking of NO chemical bonds.

Explanation:

#H_2O(l) + Delta rarr H_2O(g)#

Evaporation, the transition liquid to gas, is intrinsically an ENDOTHERMIC process, and certainly no chemical bonds have been broken in the given equation. However, a change of state has occurred. When the water evaporates its intrinsically high heat of vaporization must be supplied from somewhere, i.e. your body heat, and a cooling effect results.
