Excellent tips here. Cooling down on the bike is recommended because it is more effective than just standing around waiting. The last 5-10 minutes of my commute are for cooling down, my speed hovers in the 10mph area, and I open up the jacket (if it isn't raining) to let cool air in. I keep a package or two of clean smelling body wipes on site for the face, armpits, etc. Very effective!
