The Principles of General Health in Islam
Islam has directed both sexes to wash all of the body, with water soon after any sexual intercourse or wet dream. God says:
And if you are under an obligation to perform a total ablution, then wash yourselves.
Modern science has proven that the human body loses a part of its vitality and activity after each sexual intercourse, and will not return by any action other than washing all of the body with water. It is also obligatory upon women to wash their bodies and remove the dirt of blood after purification from the blood of menstruation. This washing recovers the womenâ€™s vitality and activity. Muslim jurists refer to other obligatory and recommended baths that make Muslims clean, in most cases, and away from dirt and filth.
Ablution is obligatory before the five daily prayers in addition to other obligatory prayers except the Funeral Prayer. It is obligatory to wash the face and the two arms, and pass the hand over, for Shias, the head and the feet. Similarly, it is recommendable, in the ritual ablution, to wash the hands and rinse the mouth and the nose in addition to the other actions. The specialist physicians mention important advantages for the ablution. They are as follows:
1. Water that is shed on the face and the hands helps in activating the dermal capillaries. This increases the heart vivacity, activates the body respiratory processes, and helps in inhalation and exhalation. Consequently, the perceptive motivated nerves are stimulated. Then, the stimulation moves to the whole cardiac, gastric, and pulmonic nerves, as well as all of the organs and glands.
2. Eyes are protected against ophthalmia because they are washed with water several times a day.
3. The nasal channels are cleaned from the germs gathering there by rinsing the nose.
4. The skin is protected against dermatoses. The face and the hands are uncovered organs that are vulnerable to the affection of microbes. Immunity will certainly be obtained if those organs are washed several times a day.
5. The oral cavity is protected against the germs that penetrate because of the pollution of hands. If the hands are always clean, they will not carry any microbe. Diseases that affect the human body through polluted hands are the digestive parasites, typhoid, and paralysis. At any rate, the ablution is the most notable means of protecting the human bodies against such serious diseases.
