Reason is because stress on a system simply means "any imposed factor which upsets the balance in rates between the forward and reverse reactions. Stress factors may be changes in concentrations [], total pressure with gases only, volume changes (which cause the pressure changes), and temperature." LeChatelier's principle is used to predict the effect of pressure and or temperature applied to a system.
