I've found success without therapy through minimal exercise over no exercise & framing things as neutral
Framing things as neutral: I'm Canadian, so during Winter I've made a point to perceive the statement "I'm cold" as a neutral statement. A sensory experience as opposed to an affliction of pain. Also focussed on relaxing my muscles in the cold, which made it less uncomfortable. Shivering & clenching up are unnecessary until the temperature has dropped to a point that you really are in pain & should either get inside or get better atire
