The modern medical science does not consider a person mentally ill, if he or she can not be given a disease label to wear. But look around you and you will see so many ‘mentals’ moving around. Most of us are unable to recognize when our mental health starts to fail. The reason for this is that when our mind is affected, our ability to reason and judge ourselves is also affected. And so people often do not realize that they are not in optimum mental health, until the things start taking bad shape.
These are some of the major factors. One factor that I have left and which is commonly considered a cause for illness is – bacteria, viruses, and parasites. What about these? Are they not a major cause of disease? Yes, they are a cause of disease – but not a major one. The ability of these microorganisms to make a person sick relies on two factors:
Body cleansing and detoxification have been referred to as an elaborate hoax used by con artists to cure nonexistent illnesses. Most doctors contend that the 'toxins' in question do not even exist.[16][17] In response, alternative medicine proponents frequently cite heavy metals or pesticides as the source of toxification, however no evidence exists that detoxification approaches have a measurable effect on these or any other chemical levels. Medical experts state that body cleansing is unnecessary as the human body is naturally capable of maintaining itself, with several organs dedicated to cleansing the blood and gut.[18]

Finally, while many testimonial and anecdotal accounts exist of health improvements following a "detox", these are more likely attributable to the placebo effect; where people actually believe that they are doing something good and healthy. Yet, there is a severe lack of quantitative data. Some changes recommended in certain "detox" lifestyles are also found in mainstream medical advice (such as consuming a diet high in fruits and vegetables). These changes can often produce beneficial effects in and of themselves, and it is accordingly difficult to separate these effects from those caused by the more controversial detoxification recommendations.
So far, I have discussed the three components of health as separate entities to understand each one of them more thoroughly. But emotional health, mental health, and physical health are not separate entities. You cannot have a healthy mind without a healthy body or healthy emotions and vice-versa. The degree to which one of these components is affected can vary from person to person, but ultimately it is the person as a whole that is affected.
L’Inrae (Institut national de recherche pour l'agriculture, l'alimentation et l'environnement) a récemment fait le point sur les recherches en cours issues du mouvement One Health - une seule santé. Dans un contexte délicat, l’approche One Health vise à impliquer l’ensemble des acteurs de la santé humaine, animale et environnementale dans une réflexion commune.

The two previous health programmes from 2008-2013, and 2003-2007 generated knowledge and evidence that served as a basis for informed policymaking and further research.This included best practice, tools, and methodologies that secured benefits for both the public-health communities and citizens directly (e.g improving diagnostic tests, supporting EU countries in developing national actions plans on cancer, improving patient care).
Le département de Santé Animale de l'Institut, dirigé par Muriel Vayssier-Taussat, étudie les interactions entre la santé animale et humaine. “Pour préserver la santé de l'Homme, une des voies est de préserver la santé animale” explique-t-elle. Mais cette protection ne doit pas être menée n'importe comment. Ces dernières années, il a été observé que la résistance aux antibiotiques avait largement augmenté chez de nombreux animaux dû à un usage massif. Ceci contribue à l'apparition de nouveaux virus plus résistants et donc potentiellement plus facilement transmissibles à l'Homme. L'unité Génétique Animale et Biologie Intégrative, dirigée par Claire Rogel-Gaillard, se consacre à l'étude de la diversité génomique en élevage, et son lien avec les santés : “Comment sélectionner des animaux qui vont être en bonne santé [...] tout en limitant l'usage d'anti-infectieux et en réduisant l'empreinte environnementale ? Il y a en fait un lien assez fort entre la durabilité des systèmes d'élevage et la santé des Hommes et animaux de la Terre.” A l'aide de travaux sur la variabilité individuelle des réponses immunitaires (aux maladies et aux vaccins) sur les animaux d'élevage, Mme Rogel-Gaillard explique qu'il “n'existe pas d'animal complètement optimal dans toutes les conditions et dans tous les environnements [...]. Une génétique optimale dans un environnement peut ne pas être optimale dans un autre.” 
Now I come back to the first question as to how ‘anger’ is generated. The moment somebody abuses you, your mind perceives it as a threat or offence based on its social learning. To counter this threat, the mind needs to prepare the body and itself for some reaction. Based on the perception of stimulus, some neuro-hormonal reactions are generated which create ’emotions’. What we perceive as ‘anger’ is the after result of that processing. Our mind generate negative thoughts towards the concerned person. The concentration level of mind increases and it is focused on the current situation. Our eyes become prominent. The winking rate decreases, muscles in face and the other parts of the body become tense in anticipation of further action.. In this state we say a person is ‘angry’. But this is the primary response occurring as a reflex phenomenon. There can be a secondary phenomenon like you can also hurl abuses or hit the person, or just walk away. This secondary reaction is based on the intensity of emotions and the integrity of the regulatory mechanisms in our brain.
Le mouvement One Health souhaite développer des synergies qui feront – selon lui – mieux progresser les soins de santé au 21e siècle ainsi que la recherche biomédicale, tout en améliorant l'efficacité des dispositifs de santé publique, grâce notamment un à élargissement et meilleur partage des connaissances scientifiques, l'amélioration de la formation médicale et de l’efficacité des soins cliniques. 

The premise of body cleansing is based on the Ancient Egyptian and Greek idea of autointoxication, in which foods consumed or in the humoral theory of health that the four humours themselves can putrefy and produce toxins that harm the body. Biochemistry and microbiology appeared to support the theory in the 19th century, but by the early twentieth century, detoxification based approaches quickly fell out of favour.[6][7] Despite abandonment by mainstream medicine, the idea has persisted in the popular imagination and amongst alternative medicine practitioners.[8][9][10] In recent years, notions of body cleansing have undergone something of a resurgence, along with many other alternative medical approaches. Nonetheless, mainstream medicine continues to view the field as unscientific and anachronistic.[9]
