He loves those who keep themselves pure and clean.
(Al-Baqara 222. Verse)
The word ablution is defined as cleansing, beauty and light in Arabic ( vudû). Islam attaches great importance to material and spiritual cleansing. Ablution has both material and spiritual benefits. A Muslim who receives ablutions many times a day creates a cleansing habit that protects him from diseases and purifies germs.
Body wrinkles and hair are the ideal places for bacteria to grow. Ablution involves washing hands, feet and hair with clean water. It is an indispensable part of daily prayers that are mandatory for every Muslim. Oral hygiene is an integral part of both preventive medicine and Islamic teachings. Genital hygiene is recommended in Islamic teachings, especially after urination and defecation, and is known to prevent urinary and vaginal infections in contemporary medicine. Circumcision is an Islamic practice. Recently, circumcision men were found to be less likely to have sexually transmitted diseases, including HIV.
You can find the ablution studies compiled from scientific articles and journals below.
Benefits of Ablution
"The skin is the largest organ in the body and contains attachments such as the epidermis, dermis, hair, nails, fat and sweat glands. Hygiene is more than just clean. Personal hygiene not only prevents the spread of certain infections, but also increases the self-esteem of individuals and contributes to mental health.
Ablution five times a day cleanses the nose from germs, dust and related pollutants. It is estimated that 500-1000 species of bacteria live on the skin. By performing ablution, potentially pathogenic microbes can be washed off the skin." 1https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4099567/
"First, ablution was significantly associated with the decrease in the risk of eczema; this supports the idea that ablution can be useful to protect the skin and reduce the symptoms of eczema. This finding shows that frequent rinsing of environmentally exposed body areas such as face, nose, ears, hands and feet can remove allergens from the skin. Therefore, ablution can prevent these agents from penetrating the skin and inflammation. In addition, ablution can reduce sweating on the skin, which causes itching and exacerbates the symptoms of eczema." 2https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5946159/
"Meticiline Resistant Staphylococcus Aureus nasal colonization can be reduced by nasal washing in ablution; it can be an easy and effective method to reduce or prevent colonization by organism and thus reduce infection with serious staphinfection diseases." 4https://www.researchgate.net/publication/314082545_Pilot_Study_to_Detect_the_Presence_of_MRSA_among_Healthcare_Workers_Who_Practice_Ablution
"The obvious reason behind washing the mouth during ablution is the removal of food particles that can cause tooth and gum problems, which is why misvak (toothbrushing) is also encouraged before ablution.
Colds can be prevented by mouthwash ing with daily water and over 30%. This simple hygienic habit can contribute to public health." 5https://www.researchgate.net/publication/293821675_UNITY_OF_HEALTH_THROUGH_YOGA_AND_ISLAMIC_PRAYER_'SALAH'
"The brain is protected from thermal damage by a brain cooling system called radiator system. When exposed to human temperature stress, high brain temperature triggers autonomic nerves to lower brain temperature. This is important because the overheated brain; can cause contractions, fainting and brain damage. Veins and a number of craniophobic gaps are the main components of this system. As the human warms up, the veins of this radiator system bring the cooled blood because its temperature is emitted by the evaporation of water (sweat or mucus) from the surfaces of the skin and craniophageal cavities. Activation of the brain cooling system thus protects the brain from thermal damage."
"You can easily see the similarity between the regions that are important in the cooling system of the brain and the areas washed while ablutioning. Thus washing the facial, ears, neck, mouth and nose cavities 4-5 times a day and soakthe scalp can keep the brain cool all day long. This is obviously a cooler head region with ablution and a healthier brain." 6https://www.researchgate.net/publication/304567179_Medical_aspects_of_ablution_and_prayer
"Long-term skin stimulation caused by the ablution process can increase cognitive abilities and prevent Alzheimer's disease. More research is needed to understand the mechanism in which ablution-based skin stimulation prevents neuro-degeneration." 7https://aanddjournal.net/article/S1552-5260(13)02008-6/fulltext
Biological Active Points
"Ablution also stimulates biological rhythms of the body, and especially biological active points (BAN), such as the idea behind Chinese reflex therapy. We still know that a human being is a complex system of electromagnetic fields, meridians, biological rhythms and so on. Human internal organs offer a bio-energetic whole, in turn less sophisticated.
They all have skin-free multi-channel binary connections, with special points that resemble buttons on "control" and "charging boards" that are responsible for specific organs.
These points are called Biological Active Points. Chinese medicine says more than 700 points and 66 have fast reflex therapy effects, and from sixty-six points, sixty-one is located in the areas required for ablution, while the other five are between the ankle and knee (an area desirable according to the Prophetic traditions to wash). Thus, ablution becomes a kind of treatment complex involving the hydro massage, thermal and physical stimulation of The Bans." https://www.researchgate.net/publication/293821675_UNITY_OF_HEALTH_THROUGH_YOGA_AND_ISLAMIC_PRAYER_'SALAH'
"The results have proven that ablution is effective in aggressiveness on students of the Department of Psychology at the Islamic University of Indonesia." 9https://journal.umy.ac.id/../download/8518/pdf_5
"There are many rumors that a person who is angry must take ablution to overcome his anger. Abdullatif al-Baghdadi, one of the Islamic philosophers, says that anger has heated the human body, that is, it raises the fire of man, so the Messenger of Allah recommends relief with ablution against anger. Sefa Saygı's findings on this subject are also remarkable. He says, pointing out that ablution relaxes man in spirit and physically: 'If anger is violent, the most effective remedy is to bring the body into contact with cold water. The refreshing and relaxing properties of water are known. It narrows the vessels on the surface of the body. Therefore, it relaxes the heart, relieves the sweat, facilitates breathing, relaxes the muscles. Therefore, it is not in vain for today's medicine to advise those with impaired nervous system to shower and come into contact with water.' This assessment is actually a interpretation of the prophet Muhammad(h): 'Anger is satan, and satan is created from fire. Fire is extinguished with water. So let one of you get up and ablutions when you get angry.' "10https://dergipark.org.tr/tr/download/article-file/495230
As you can see, ablution is a worship with a wide range of common physical and spiritual effects, rather than just cleaning. So much so that it even caused many non-Muslims to become Muslims;
"On a hot day, I wanted to sit next to your friend in the shaman and wash my face to cool off a little bit. And my friend said, "If you want to cool off, at least get ablutions." He showed me how to do it, and I did. It was like I felt a post-meditation relief that I spent hours working in two minutes. I asked my friend if there was anything special about ablution. Because it didn't feel like a faith to me, it seemed like a method. And he said, "We do it because God commands you." So I thought, 'How good is God', and from that day on, I began to investigate Islam."
