>>1168242I take cold showers actually, I've found it works better than caffeine to wake me up, and I don't get headaches anymore. Though I attribute that to dropping caffine not taking cold showers.
I also used to swim during the winter, I lived on a river, and would jump in and scrub clean before going into the sauna. It was awesome to go from shivering uncontrollably, and painfully numb extremities to being so warm you have to step out.
