Hm...I wonder if a foam blower in the shower might make for reduced energy use, as well.

Hmmm. Not all air in water is beneficial. Specifically those shower heads that introduce air as a means to seemingly make more from less water. In this case the introduced air is supposed to act to cool the stream of water, requiring more heated water in the hot/cold mix in order to feel comfortable. To try and sort out what is actually best for environmental reasons is more than my head can handle.

I think bubbles on top of your bath would do this, but bubbles in the bath (like a hot tub) would cool it faster.
As far as foam in a shower - it is not the water that needs to be kept warm, it is you. Take a shower inside a foam wetsuit or bathrobe perhaps? Shower gels and oils can help retain some heat on the body.
I never seem to get warm from a shower even with the water very hot, unless the room itself is heated to steamy saturation. I stay warmer with a clothed, almost-dry sponge bath or spot-clean, and heat up chilled extremities by soaking my hands (or feet) in warm water. I use a hot bath occasionally when I am too chilled to fall asleep. A shower just doesn't deliver enough heat to offset the chill from drying off again.
Bubbles keep our bath hot is fact because bubbles insulate the water and remains hot. This bubbles bath gives the stimulation to the body and give the complete relax. This hot bubbled bath give the good comfortable relax to the whole body and at the take a time in the tub. And also play the silent or the melodious music while bath it give relax to your mind.

As Erica said, its not the shower that needs to be warm, its you. I plan on emulating sun frost's idea for a shower. Basically, the shower stall is sealed up tight, allowing no steam (and therefore less heat) to exit the shower. This keeps the temperature inside the stall higher while allowing one to use cooler water, but still feel warm.
