What about focus? Laying down means different blood pressure in brain than it is in vertical position.

I don’t think focus would be a problem but sleeping problems. When body is accustomed to stay awake even when lying then it’s much harder to fall asleep.

Better? It is relaxed pose. My brain usually slows down when lying on bed.
