Atmospheric Pressure

In the Holy Qur’an Allah, All-Mighty, says:

“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 were climbing up into the sky. Thus Allah puts wrath on those who believe not.” (Surat Al-An’am 6:125).

This verse is an example of the scientific miracles of the Holy Qur’an, and it also provides clear evidence of Prophet Muhammad’s being Allah’s Prophet and Messenger.

It has now been proved in medical science of aviation and space that excessive heights above the Earth’s surface cause physiological changes in the human body that are manifested by a feeling of closeness and constriction in the breast until one reaches the critical stage mentioned in the Holy Qur’an:

“He makes his breast closed and constricted, as if he were climbing up into the sky”.

This is because the higher one goes up into the sky, the lesser atmospheric pressure and the lesser oxygen is there.

If man goes up to a height of 10,000 feet above sea level, he feels decrease of both oxygen and atmospheric pressure. If he goes higher up to 16,000 feet high, his pulse increases and so do his breathing and blood pressure, in order to provide his body with the necessary oxygen.

If, however, he goes up higher to 25,000 feet high, his body fails to cope with such an unfamiliar height. So what happens? Certain symptoms begin to show.

First, he feels that his breast is closed and constricted: “He makes his breast closed and constricted, as if he were climbing up into the sky”.
