Quran’s scientific miracle in revealing the fact of “chest constriction at high altitudes”
By: mohamad massarweh
Quran has revealed , fourteen centuries ago , that chest constricts when gaining altitude;
( And whomsoever Allah wills to guide, He opens his breast to Islam, and whomsoever He wills to send astray, He makes his breast closed and constricted, as if he is climbing up to the sky )
Gas molecules exert pressure on the walls of their container . According to the law of gases if the same amount of a gas was put it in a large and small containers , gas molecules will be densier and exert higher pressure in the small volume . Air density decreases as the distance from the earth surface increaes therefore we inhale less and less oxygen as we get higher consequently, heart rate increases as well as respiration. The decreased volume of the inhaled air exert less air pressure onto the lungs walls thereby reduces their capacity ( He makes his breast closed and constricted ). Midecine defines alttitudes of 8 kilometers and above as " danger zone" where humans will suffer from severe lack of oxygen which can be fatal.
