In fact, diseases of the vertebral column are very rare among Muslims who observe Salat, which includes such movements as bowing, prostrating, and standing up, which very useful to the vertebral column. All kinds of Arthritis are also rare among Muslims who observe Salat.
Also, varices and deep vein clots are rare among Muslims, and so is vascular congestion in the pelvis, which causes hemorrhoids and uterus hemorrhage.
Difficulties in breathing, which are caused by increase of Carbon Dioxide in the lungs, are also rare among Muslims, because compulsory exhalation caused by bowing and prostration activates the heart and lungs.
Alzheimer and senility are also uncommon among Muslims, because prostration causes more blood to flow into the brain and prevents such diseases that are caused by deficiency of blood in the brain. Therefore, prostration forces more blood to flow into blood vessels of the head by the force of gravity. In this context, Allah’s Messenger, (PBUH), used to bid Bilal, the venerable Companion, may Allah be pleased with him, “O Bilal! Call (people) to Salat (Islamic Prayer)! Relieve us with it!” [Narrated by Abu Dawood (4985) and Ahmad (23137)] This is because Salat (Islamic Prayer) causes both physical and spiritual comfort.

An experiment carried out by some scientists showed that when the head is lowered downwards, blood gathers therein and pressure on arteries increases. But when the head is then suddenly raised up, the pressure decreases. This rise and fall of pressure makes blood vessel more flexible. This means that a person whose blood vessels are flexible can bear 23 degrees of pressure, while a person who does not perform Salat (Islamic Prayer) cannot bear even 18 degrees of pressure, the blood vessels of his brain will be torn out at such degree of pressure, and he will have a brain failure.
Uterus overturn, which is common among women, is treated by special exercises that resemble greatly movements done while performing Salat (Islamic Prayer).
