I get outside for an hour before work everyday and try to get acclimated. Nude except for shoes, for some reason my feet get cold well before the rest of me. Being naked in the cold still feels good and it helps to get moving in the morning!
Our thermostat stays at 68F all winter. The hot tub is on the deck about 20 feet away from the doorwall. When it snows, I always shovel the entire deck nude to experience the cold. It usually takes me about 20 minutes to get the job done (barefoot too). I drag the trash can out to the end of the driveway through the snow, also nude and barefoot. It just makes me feel more alive. Every morning before I get in the shower, about 4:30 am, I make a nude trip to the end of the drive and check the mailbox. I've only been seen once in 11 years. No big deal.
