A non Muslim Uropean Scientist described the Sajdah as the best way to inactive the electro magnatic waves that human body has to take every day from our daily used insruments and mechineries and even electric light. He said when a Muslim touch his forehead on the ground in sajdah the electro magnatic waves of his body go to the earth and it's become inactive. Thus, he who regular perform salat and sajdah, he stays free from various dangerous diseases by the grace of Almighty Allah.
Sajdah is really a unique position as this is the only position in which brain (or head) becomes lower than the heart and hence for the first time the blood gushes towards the brain with full force whereas in all other positions (even when lying) brain is above the heart when it has to work against gravity to send blood to the brain.
In the position of Sijdah, with Sajdah as a result of enhanced blood supply the brain receive more nourishment and it has good effect upon memory, vision, hearing, concentration, phyche and all other cognitive abilities. People who offer their prayer regularly have more will power and may overcome the issues associated with existence throughout a lot better manner. They have less incidence of headaches , psychological problems and other defects of cognitive function.
In the unique position of sijdah the neck muscles receive greatest physical exercise. They have to bear the load when the forehead lies at the ground hence the the neck muscles become stronger. Anybody can take note this stressed strain at the neck muscles in the position of Sajdah especially this active motion of the neck and the facial muscles when the head is being lifted. (e.g one inch above the ground) in addition to it will be observed that they are in a really very active motion.
It is uncommon that a person who offers his prayers regularly will get the usual neck myalgias or servical spondylosis as the neck muscles particularly become very strong due to 34 sajdahs offered daily in five prayers.
Position of sajdah is also said to be a good treatment for the retroversion of uterus, a disease of women.
Most of us don't know that the position of sajdah is an excellent exercise for men (for manpower). It may be a good information to the viagra dependents.
After performing sajdah either the Musulli stands up or he sits to pray Attahiyyat. In this position the person sits calmly while his hand rests at his things which are folded backwards.This is much similar to the relaxation position of yoga and has soothing effect upon one's health and mentation.
The Prophet Muhammad (Sallallaahu alayhi wa sallam)used to elongate the position of Ruku (bending) and sajdah positions and he advised to do so.In the light of the above facts it is appropriate to say that from medical point of view as well this advice is a golden rule for health.
Finally it must be reminded that prayer is not meant to be an exrecise. However there are a lot of medical advantages associated with it.
Still the best blessing is the peace of mind, which a person derives by the accomplishment of his duty to Allah by fulfilling an obligation.
