AndrewKFletcher ::: Favorites Question:Why does sleeping on a five degree head up angle reduce the heart rate by 10-12 beats per minute? And the respiration rate by 4-5 breaths per minute, yet increases circulation and the strength of the heart and respiration stroke? 07-08-21 06:22:18 _____________________________________________________
