A Guide to Traditional, 3D and 4D Baby Ultrasounds, Including Pictures, Safety and What to Expect. You may be worried about the cost of an ultrasound, or if itâs covered by your health insurance. Typically, the type of ultrasound (transvaginal) done very early in pregnancy is performed in an obstetricianâs office by the obstetrician. Thus, it is just part of the regular office visit and almost certainly covered by most forms of insurance in the United States.
The answer is that your heart does not stop or skip a beat when you sneeze â there is no scientific basis for this old belief. (Phew!) Sometimes, the heartâs rate or rhythm will change in relation to a sneeze, but in no way at all does it âstop.â.
Another is that people thought that sneezing could open you up to losing your soul or being invaded by the Devil or evil spirits and saying it was supposed to protect you from that. Another possibility is that people just didn't understand sneezing and so saying it was just a response to something worrisome. A couple other possibilities are mentioned in the source but those are the main ones imo. Source(s): http://en.wikipedia.org/wiki/Bless_you.
