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 of the body and contains attachments such as epidermis, dermis, hair, nails, oil and sweat glands. Hygiene is more than just clean. Personal hygiene not only prevents the spread of certain infections, but also increases the self-confidence of individuals and contributes to mental health.
Taking ablutions five times a day cleans the nose from germs, dust and related pollutants. It is estimated that 500-1000 bacterial species live in the skin. By performing ablution, potentially pathogenic microbes can be washed on the skin." 1https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4099567/
"First, ablution was significantly associated with a reduced risk of eczema; this supports the idea that ablution can be useful to protect the skin and reduce the symptoms of eczema. This finding suggests that frequent rinsing of environmentally exposed body areas such as the face, nose, ears, hands and feet can remove allergens from the skin. Therefore, ablution can prevent penetration and inflammation of these agents from the skin. 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/
"Metycillin Resistant Staphylococcus Aureus nasal colonization can be reduced by nasal washing in the ablution; this can be an easy and effective method to reduce colonization by the organism or prevent it and thus reduce infection with serious staphylococcal 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 pre-ablution musk (tooth brushing) is also encouraged.
Colds can be prevented by gargling with daily water 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 craniofacial regions, which are important in the cooling system of the brain, and areas that are washed when ablution. Thus, washing the facial, ears, nape, mouth and nasal cavities 4-5 times a day and soaking the scalp can keep the brain cool all day long. This obviously means a cooler head area and a healthier brain with ablution." 6https://www.researchgate.net/publication/304567179_Medical_aspects_of_ablution_and_prayer
"Prolonged skin stimulation caused by the ablution process can increase cognitive abilities and prevent Alzheimer's disease. More research is needed to understand the mechanism by which ablution-based skin stimulation prevents neuro-degeneration." 7https://aanddjournal.net/article/S1552-5260(13)02008-6/fulltext
Biological Active Points
"Ablution also stimulates the biological rhythms of the body, and especially biological active points (BAN), such as the idea behind Chinese reflex therapy. We still know that a person has a complex system of electromagnetic fields, meridians, biological rhythms and so on. Human internal organs, in turn, offer a less sophisticated bio-energetic whole.
All have multichannel binary connections that are insoluble with leather, whose functions are home to special points that resemble buttons on the "control" and "charging boards" responsible for certain organs.
These points are called Biological Active Spots. Chinese medicine says more than 700 points and 66 have rapid reflex therapy effects, sixty-six of which are located in areas required for ablution, while the other five are located between the ankle and knee (an area desirable according to Prophetic traditions to wash). Thus, ablution becomes a kind of treatment complex that includes hydro massage of BAN's, thermal and physical stimulation." 8https://www.researchgate.net/publication/293821675_UNITY_OF_HEALTH_THROUGH_YOGA_AND_ISLAMIC_PRAYER_'SALAH'
"There is a lot of talk about a person who is angry that he needs to be absoled in order to overcome his anger. Abdullatif al-Baghdadi, an Islamic philosopher, says that anger exacerbates the human body, that is, it raises the temperature of man, so the Messenger of Allah advises to relax with ablution against anger. Sefa Respectful's findings in this regard are also noteworthy. He says: 'If anger is severe, the most potent remedy is to bring the body into contact with cold water. The refreshing and soothing properties of water are known. Narrows the veins on the surface of the body. Therefore, it relaxes the heart, removes sweat, facilitates breathing, relaxes the muscles. So it's not in vain for today's medicine to advise those with nervous breakdowns to take a shower, come into contact with water.' This assessment is actually a interpretation of the following hadith of muhammad (sav) in our opinion: 'Anger is the devil, and satan is made of fire. Fire is extinguished with water. If so, when one of you gets angry, get up and ablution.' "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."
