I agree with Goodnightelizabeth. You should use lukewarm water all of the time. The key is to treat your skin gently, and not shock it with extreme temperatures. Hot water also has the danger of causing broken capillaries. Cold water cannot close the pores; that's a myth. Pores cannot open and close.
I will go with the lukewarm water washing with a splash of cold at the end. Seems I've been using very hot water recently because of the extremely cold temps here in the northeast US. Gotta break the habit I guess. Thanks for all your insights.
