[YEA] Forget all about cold showers! Much too brutal. Cold water baths are the thing but then only early in the morning and before the brain is in gear & knows what is happening. You run the cold water bath tap whilst brushing your teeth & washing your face.This gives you a perfect 12 inches of water to which you add some good quality lavender lotion. Then it's in you go, feet first folloiwed by the bottom. A good sponge down of the torso follows. Then stand up & soap the forked bit. After this lie down slowish until everything but the head is submerged. ( At this point I say my morning prayers). A final sponge down completes the process & you step out of the tub feeling taut, fit & very self-righteous having been no more than about 3 minutes in the bath. I've been doing this for nearly 25 years now & am healthy & fit as a fiddle.
