The United States dietary guidelines, based on the 2005 Institute of Medicine report, recommend that the general population aim for sodium levels of 1,500 to 2,300 milligrams a day because those levels will not raise blood pressure.
One of the symptoms of the plague was coughing and sneezing, and it is believed that Pope Gregory VII suggested saying âGod bless youâ after a person sneezed in hopes that this prayer would protect them from an otherwise certain death. The expression may have also originated from superstition.
Another explanation is that when people sneezed it was believed that the heart would miss a beat; in that microsecond, the skip would allow the devil to enter the body. Therefore, saying God bless you would stop the devil from entering one's body uninvited.
