How to get up early in cold weather

My practice is to turn on the music when I know I have to stay in bed. That's very effective. Of course, I will update the songs regularly according to my own preferences. That's really good, at least I think so. The book says it's good for your health to turn on the music in the morning and taste it slowly. I like that very much. I will wake up naturally when I hear music. You can also listen to the light music of guzheng or pipa, which feels good and lays a good foundation for a happy day. For reference only.
