To be clear, it's not that sleeping while horizontal is better than being awake while horizontal. We all need solid sleep, but being horizontal should otherwise be minimized as it is the ultimate sedentary lifestyle.[0] This causes heart atrophy.

Your references are due to sedentary, not laying down. You can have a sedentary life standing in place most of the day. Likewise, the problem is being sedentary, not what position your sedentary in.
