Health care, or healthcare, refers to the treatment and management of illness, and the preservation of health through services offered by the medical, pharmaceutical, dental, clinical laboratory sciences (in vitro diagnostics), nursing, and allied health professions. Health care embraces all the goods and services designed to promote health, including “preventive, curative and palliative interventions, whether directed to individuals or to populations”.

Before the term health care became popular, English-speakers referred to medicine or to the health sector and spoke of the treatment and prevention of illness and disease.
When considering the history of Universal Health Care and the giants of Canadian politics, T.C. Douglas surely stands at the forefront. Tommy Douglas was a remarkable Canadian whose contributions have helped to shape the great nation. Although he is most famous as the founding father of Medicare, the most advanced health-care system in the world, Douglas’ contributions to Saskatchewan and Canada were tremendous.

Tommy Clement Douglas was born on October 20, 1904 in Falkirk, Scotland. In 1911, Tommy, his mother and his sister moved to Winnipeg to join his father who had moved there the previous year. Shortly after settling in Winnipeg, Tommy was diagnosed with osteoarthritis in his right leg. Tommy’s family was not wealthy and subsequently his family could not pay for the best or most immediate treatment. The delay nearly cost Tommy his leg. This experience marked the beginning of Tommy’s quest for universal, public health care.

In 1961, In Saskatchewan, Canada, The North American Medical Establishment tried to defy Medicare, Douglas’s top priority project, and Saskatchewan politics became an intense battleground. This turbulent time was marked by the Doctor’s Strike as the physicians of the province protested socialized healthcare. However, the striking doctors were no match for Douglas. When the dust settled with the resolution of the strike, Medicare in Saskatchewan was born. Douglas showed Canada two things: that it was possible to develop and finance a universal Medicare system and that the medical profession could be confronted. Had Douglas not have made these first ground breaking steps, national Medicare would never have happened. This movement and political struggle helped pave the way for universal health care on a global scale. Since then, Canada's system of health care has been imitated and implemented in various countries around the world.

Health care can encompass a wide number of settings - from the informal (house calls, emergency medicine at an accident spot) to settings like nursing homes or rest homes, to 'typical' medical settings like doctor's practices, clinics and hospitals.

A health care provider or health professional is an organization or person who delivers proper health care in a systematic way professionally to any individual in need of health care services. A health care provider could be government, the health care industry, a health care equipment company, an institution such as a hospital or medical laboratory, physicians, dentists, support staff, nurses, therapists, psychologists, pharmacists, chiropractors, and optometrists.
Emergency medicine is a speciality of medicine that focuses on the diagnosis and treatment of acute illnesses and injuries that require immediate medical attention. While not usually providing long-term or continuing care, emergency medicine physicians diagnose a wide array of pathology and undertake acute interventions to stabilize the patient. These professionals practice in hospital emergency departments, in the prehospital setting via emergency medical service and other locations where initial medical treatment of illness takes place. Just as clinicians operate by immediacy rules under large emergency systems, emergency practioniers aim to diagnose emergent conditions and stabilize the patient for definitive care.
Chronic care management encompasses the oversight and education activities conducted by professionals to help patients with chronic diseases such as diabetes, high blood pressure, lupus, multiple sclerosis and sleep apnea learn to understand their condition and live successfully with it. This term is equivalent to disease management (health) for chronic conditions. The work involves motivating patients to persist in necessary therapies and interventions and helping them to achieve an ongoing, reasonable quality of life.
Patient safety is a new healthcare discipline that emphasizes the reporting, analysis, and prevention of medical error that often lead to adverse healthcare events. The frequency and magnitude of avoidable adverse patient events was not well known until the 1990s, when multiple countries reported staggering numbers of patients harmed and killed by medical errors. Recognizing that healthcare errors impact 1 in every 10 patients around the world, the World Health Organization calls patient safety an endemic concern. Indeed, patient safety has emerged as a distinct healthcare discipline supported by an immature yet developing scientific framework. There is a significant transdisciplinary body of theoretical and research literature that informs the science of patient safety. The resulting patient safety knowledge continually informs improvement efforts such as: applying lessons learned from business and industry, adopting innovative technologies, educating providers and consumers, enhancing error reporting systems, and developing new economic incentives. This patient safety page provides an evidence-based and peer-reviewed forum to learn about contemporary error and adverse event knowledge.

Traditional Chinese medicine

Traditional Chinese medicine (also known as TCM, simplified Chinese: 中医; traditional Chinese: 中醫; pinyin: zhōngyī) includes a range of traditional medical practices originating in China. Although well accepted in the mainstream of medical care throughout East Asia, it is considered an alternative medical system in much of the western world.

TCM practices include such treatments as herbal medicine, acupuncture, dietary therapy, and both Tui na and Shiatsu massage. Qigong and Taijiquan are also closely associated with TCM.

TCM theory originated thousands of years ago through meticulous observation of nature, the cosmos, and the human body. Major theories include those of Yin-yang, the Five Phases, the human body Channel system, Zang Fu organ theory, six confirmations, four layers, etc.

Ancient (classical) TCM history

Much of the philosophy of traditional Chinese medicine derives from the same philosophy that inform Taoist and Buddhist thought, and reflects the classical Chinese belief that the life and activity of individual human beings have an intimate relationship with the environment on all levels.

In legend, as a result of a dialogue with his minister Qibo (岐伯), the Yellow Emperor (2698 - 2596 BCE) is supposed by Chinese tradition to have composed his Neijing Suwen (《内经·素问》) or Inner Canon: Basic Questions, also known as the Huangdi Neijing (Yellow Emperor's Inner Canon). The book's title is often mistranslated as Yellow Emperor's Classic of Internal Medicine. Modern scholarly opinion holds that the extant text of this title was compiled by an anonymous scholar no earlier than the Han dynasty just over two-thousand years ago.

During the Han Dynasty (202 BC –220 AD), Zhang Zhongjing (张仲景/張仲景), the Hippocrates of China, who was mayor of Chang-sha toward the end of the 2nd century AD, wrote a Treatise on Cold Damage, which contains the earliest known reference to Neijing Suwen. Another prominent Eastern Han physician was Hua Tuo (c. 140 – c. 208 AD), who anesthetized patients during surgery with a formula of wine and powdered hemp. Hua's physical, surgical, and herbal treatments were also used to cure headaches, dizziness, internal worms, fevers, coughing, blocked throat, and even a diagnosis for one lady that she had a dead fetus within her that needed to be taken out. The Jin dynasty practitioner and advocate of acupuncture and moxibustion, Huang-fu Mi (215 - 282 AD), also quoted the Yellow Emperor in his Jia Yi Jing (甲乙经/甲乙經), ca. 265 AD. During the Tang dynasty, Wang Bing claimed to have located a copy of the originals of the Neijing Suwen, which he expanded and edited substantially. This work was revisited by an imperial commission during the 11th century AD.

There were noted advances in Chinese medicine during the Middle Ages. Emperor Gaozong (r. 649–683) of the Tang Dynasty (618–907) commissioned the scholarly compilation of a materia medica in 657 that documented 833 medicinal substances taken from stones, minerals, metals, plants, herbs, animals, vegetables, fruits, and cereal crops.[2] In his Bencao Tujing ('Illustrated Pharmacopoeia'), the scholar-official Su Song (1020–1101) not only systematically categorized herbs and minerals according to their pharmaceutical uses, but he also took an interest in zoology. For example, Su made systematic descriptions of animal species and the environmental regions they could be found, such as the freshwater crab Eriocher sinensis found in the Huai River running through Anhui, in waterways near the capital city, as well as reservoirs and marshes of Hebei.

Contact with Western culture and medicine has not displaced TCM. While there may be traditional factors involved in the persistent practice, two reasons are most obvious in the westward spread of TCM in recent decades. Firstly, TCM practices are believed by many to be very effective, sometimes offering palliative efficacy where the practices of Western medicine fail or unable to provide treatment, especially for routine ailments such as flu and allergies, or when Western medicine fails to relieve patients suffering from chronic ailments. TCM has been shown to be effective[citation needed] in the treatment of chronic, functional disorders, such as migraines and osteoarthritis, and is traditionally used for a wide range of functional disorders. Secondly, TCM provides an alternative to otherwise costly procedures whom many can not afford, or which is not covered by insurance. There are also many who turn to TCM to avoid the toxic side effects of pharmaceuticals.

TCM of the last few centuries is seen by at least some sinologists as part of the evolution of a culture, from shamans blaming illnesses on evil spirits to "proto-scientific" systems of correspondence;[8] any reference to supernatural forces is usually the result of romantic translations or poor understanding and will not be found in the Taoist-inspired classics of acupuncture such as the Huang Di Nei Jing. The system's development has, over its history, been analysed both skeptically and extensively, and the practice and development of it has waxed and waned over the centuries and cultures through which it has travelled[9] - yet the system has still survived thus far. It is true that the focus from the beginning has been on pragmatism, not necessarily understanding of the mechanisms of the actions - and that this has hindered its modern acceptance in the West. This, despite that there were times such as the early 18th century when "acupuncture and moxa were a matter of course in polite European society"

The term "TCM" describes the modern practice of Chinese medicine as a result of sweeping reforms that took place after 1950 in the People's Republic of China. The term "Classical Chinese medicine" (CCM) often refers to medical practices that rely on theories and methods dating from before the fall of the Qing Dynasty (1911). Advocates of CCM portray it as less influenced by Western and political agendas than TCM.

Birth control

Birth control, sometimes synonymous with contraception, is a regimen of one or more actions, devices, or medications followed in order to deliberately prevent or reduce the likelihood of pregnancy or childbirth. "Contraception" may refer specifically to mechanisms that are intended to reduce the likelihood of a sperm cell fertilizing the egg. Birth control is commonly used as part of family planning.

The history of birth control began with the discovery of the connection between coitus and pregnancy. The oldest forms of birth control included coitus interruptus, pessaries, and the ingestion of herbs that were believed to be contraceptive or abortifacient. The earliest record of birth control use is an ancient Egyptian set of instructions on creating a contraceptive pessary.

Different methods of birth control have varying characteristics. Condoms, for example, are the only methods that provide significant protection from sexually transmitted diseases. Cultural and religious attitudes on birth control vary significantly.
Probably the oldest methods of contraception (aside from avoiding vaginal intercourse) are coitus interruptus, lactational, certain barrier methods, and herbal methods (emmenagogues and abortifacients).

Coitus interruptus (withdrawal of the penis from the vagina prior to ejaculation) probably predates any other form of birth control. Once the relationship between the emission of semen into the vagina and pregnancy was known or suspected, some men began to use this technique. This is not a particularly reliable method of contraception, as few men have the self-control to correctly practice the method at every single act of sexual intercourse.[1] Although it is commonly believed that pre-ejaculate fluid can cause pregnancy, modern research has shown that pre-ejaculate fluid does not contain viable sperm.

There are historic records of Egyptian women using a pessary (a vaginal suppository) made of various acidic substances and lubricated with honey or oil, which may have been somewhat effective at killing sperm. However, it is important to note that the sperm cell was not discovered until Anton van Leeuwenhoek invented the microscope in the late 17th century, so barrier methods employed prior to that time could not know of the details of conception. Asian women may have used oiled paper as a cervical cap, and Europeans may have used beeswax for this purpose. The condom appeared sometime in the 17th century, initially made of a length of animal intestine. It was not particularly popular, nor as effective as modern latex condoms, but was employed both as a means of contraception and in the hopes of avoiding syphilis, which was greatly feared and devastating prior to the discovery of antibiotic drugs.

Various abortifacients have been used throughout human history in attempts to terminate undesired pregnancy. Some of them were effective, some were not; those that were most effective also had major side effects. One abortifacient reported to have low levels of side effects—silphium—was harvested to extinction around the 1st century.[5] The ingestion of certain poisons by the female can disrupt the reproductive system; women have drunk solutions containing mercury, arsenic, or other toxic substances for this purpose. The Greek gynaecologist Soranus in the 2nd century suggested that women drink water that blacksmiths had used to cool metal. The herbs tansy and pennyroyal are well-known in folklore as abortive agents, but these also "work" by poisoning the woman. Levels of the active chemicals in these herbs that will induce a miscarriage are high enough to perilously damage the liver, kidneys, and other organs. However, in those times where risk of maternal death from postpartum complications was high, the risks and side effects of toxic medicines may have seemed less onerous. Some herbalists claim that black cohosh tea will also be effective in certain cases as an abortifacient.

Aside from abortifacients, herbal contraceptives in folklore have also included a few preventative measures. Hibiscus rosa-sinensis, known in Ayurveda as a contraceptive, may have antiestrogenic properties. Papaya seeds, rumored to be a male contraceptive, have recently been studied for their azoospermic effect on monkeys.

During the medieval period, physicians in the Islamic world listed many birth control substances in their medical encyclopedias. Avicenna listing 20 in The Canon of Medicine (1025) and Muhammad ibn Zakariya ar-Razi listing 176 in his Hawi (10th century). This was unparalleled in European medicine until the 19th century.

The fact that various effective methods of birth control were known in the ancient world sharply contrasts with a seeming ignorance of these methods in wide segments of the population of early modern Christian Europe. This ignorance continued far into the 20th century, and was paralleled by eminently high birth rates in European countries during the 18th and 19th centuries. Some historians have attributed this to a series of coercive measures enacted by the emerging modern state, in an effort to repopulate Europe after the population catastrophe of the Black Death, starting in 1348. According to this view, the witch hunts were the first measure the modern state took in an attempt to eliminate knowledge about birth control within the population, and monopolize it in the hands of state-employed male medical specialists (gynecologists). Prior to the witch hunts, male specialists were unheard of, because birth control was naturally a female domain.

Presenters at a family planning conference told a tale of Arab traders inserting small stones into the uteruses of their camels in order to prevent pregnancy, a concept very similar to the modern IUD. Although the story has been repeated as truth, it has no basis in history and was meant only for entertainment purposes. The first interuterine devices (which occupied both the vagina and the uterus) were first marketed around 1900. The first modern intrauterine device (contained entirely in the uterus) was described in a German publication in 1909. The Gräfenberg ring, the first IUD that was used by a significant number of women, was introduced in 1928.

The rhythm method (with a rather high method failure rate of ten percent per year)[citation needed] was developed in the early 20th century, as researchers discovered that a woman only ovulates once per menstrual cycle. Not until the 1950s, when scientists better understood the functioning of the menstrual cycle and the hormones that controlled it, were methods of hormonal contraception and modern methods of fertility awareness (also called natural family planning) developed.

Margaret Sanger was an American birth control activist and the founder of the American Birth Control League (which eventually became Planned Parenthood). She was instrumental in opening the way to access birth control.

In 1960 the FDA approved the first form of hormonal birth control, the combined oral contraceptive pill.

Healthy diet

A healthy diet is one that helps maintain or improve health. It is important for the prevention of many chronic disease such as: obesity, heart disease, diabetes, and cancer.


A health diet involves consuming appropriate amounts all of the food groups, including an adequate amount of water. Nutrients can be obtained from many different food, thus a healthy diet may vary widely.
The WHO makes the following 6 recommendation with respect to both populations and individuals:

Achieve an energy balance and a healthy weight
Limit energy intake from total fats and shift fat consumption away from saturated fats to unsaturated fats and towards the elimination of trans-fatty acids
Increase consumption of fruits and vegetables, legumes, whole grains and nuts
Limit the intake of simple sugars
Limit salt / sodium consumption from all sources and ensure that salt is iodized
Other recommendation include:

Sufficient essential amino acids ("complete protein") to provide cellular replenishment and transport proteins. All essential amino acids are present in animals. A select few plants (such as soy and hemp) give all the essential acids. A combination of other plants may also provide all essential amino acids (except rice and beans which have limitations).
Essential micronutrients such as vitamins and certain minerals.
Avoiding directly poisonous (e.g. heavy metals) and carcinogenic (e.g. benzene) substances;
Avoiding foods contaminated by human pathogens (e.g. E. coli, tapeworm eggs).

Fruits and vegetables
The WHO recommends a minimum of 400g of fruit and vegetables per day. This groups excludes potatoes and other starchy tubers.[3] Fruits and vegetables also prevent several micronutrient deficiencies.


Sex
While a moderate amount of sex is required for health, a high amount of sex can have detrimental effects on blood pressure.


Healthy diets

DASH diet
See main article: DASH diet


Unhealthy diets
An unhealthy diet is a major risk factor for a number of chronic diseases including: high blood pressure, diabetes, abnormal blood lipids, overweight/obesity, cardiovascular diseases, and cancer.

The WHO estimates that 2.7 million deaths are attributable to a diet low in fruit and vegetable every year. Globally it is estimated to cause about 19% of gastrointestinal cancer, 31% of ischaemic heart disease, and 11% of strokes. Thus making it one of the leading preventable causes of death worldwide.


Food additive controversy
Some claim that food additives, such as artificial sweeteners, colorants, preserving agents, and flavorings may cause health problems such as increasing the risk of cancer or ADHD.

Several recent studies have also shown that artificial sweeteners, such as Aspartame, may increase risks of obesity. A study led by Sharon P. Fowler found that drinking two cans of either regular or diet soft-drink a day increased the risk of becoming overweight or obese by 50%.

There is a lot of controversy around the use of Aspartame alone, and one test has shown that the Aspartame in Diet Coke "decomposes into formaldehyde, methyl alcohol, formic acid, diketopiperazine and other toxins. In a study on 7 monkeys 5 had grand mal seizures and one died, a casualty rate of 86%." It has also been shown in studies that Diet Coke may cause 92 symptoms listed by the FDA, one of them being Death. However, Aspartame has not been actually "proven" to be dangerous in any way, and the makers of it claim that it is one of the safest artificial sweeteners, and that it has been tested several times by their company.
