Health is a measure of the general condition of the body on a macroscopic and microscopic level, including the presence of any wounds, microbial infections and, in many cases, mental illnesses. The adjectival form of the word, healthy, often refers to the absence of impairing disease.

There are several factors influencing a person's health, including:

  • diet - drinking water
  • stress - rest
  • stamina
  • living conditions - pollution
  • personal hygiene - smoking
  • genetic factors
  • sedentarism - exercise

Exercise is health!

Be physically active. Any activity’s better than none. Health benefits grow the more you do. [1]

Nutrition

As far as academic achievement in university and college students, results suggest that diet may be associated with academic achievement, with the majority of studies associating more favourable dietary intake with higher academic achievement.[1]

Nutrition is the study that deals with food (nutrients) and nourishment.

There are several nutrients that the human body needs to acquire: protein, carbohydrates, fat, vitamins, minerals and water. Other elements include fiber and micronutrients like antioxidants, trace elements, and phytochemicals.

Nutrient-dense foods are those that provide substantial amounts of vitamins and minerals and relatively fewer calories.

The first principle of a healthy diet is simply to eat a wide variety of foods. [2] A poor diet can have an injurious impact on health.

Preventive medicine and health

See also: Preventive medicine

Preventive medicine refers to medical methods taken to prevent diseases and/or injuries rather than treating them once they have already occurred.

According to the medical journal Lancet:

A substantial proportion of poor health in populations is preventable. Previous work from the Global Burden of Diseases, Injuries, and Risk Factors Study1 suggests that nearly half of all health burden in the USA is attributable to a list of 84 modifiable risk factors. Globally, it is also generally accepted that a quarter, or perhaps up to half, of all deaths fall into the category of preventable deaths,2 making illness that can at least theoretically be avoided an accepted part of our health accounting.

In The Lancet Public Health, Howard Bolnick and colleagues extend this logic in the US context and quantify the proportion of US health-care spending in 2016 that was due to preventable causes.3 They found that more than a quarter (27·0%, 95% uncertainty interval [UI] 25·7–28·4) of health-care spending was due to these preventable illnesses.[2]
