Environment and longevity: where people live

Chapter 1: Environment and Health Relations: Fundamentals

1.1. Determination of the environment and its components

The environment, in a broad sense, is a combination of natural, anthropogenic and social factors that affect human life and activity. These factors interact with each other, forming complex ecosystems that determine the conditions of existence. The key components of the environment are:

Atmosphere: The composition of the air, the concentration of pollutants (for example, solid particles, ozone, nitrogen oxides and sulfur), temperature, humidity, atmospheric pressure, ultraviolet radiation.
Hydrosphere: Water quality (drinking and surface), the presence of pollutants (for example, heavy metals, pesticides, bacteria), the availability of water resources, the nature of water bodies (rivers, lakes, oceans).
Lithosphere: The composition of the soil, the presence of minerals, geological features (for example, the presence of radon), the level of the radiation background, the stability of the soil.
Biosphere: A variety of plant and animal world, the presence of pathogenic microorganisms, pollen, allergens, the influence of biogenic factors on health.
Socio-economic environment: The level of infrastructure development (transport, housing, healthcare, education), the availability of medical services, the level of income of the population, social support, cultural features.
Artificial environment (anthropogenic): Urbanization, industry, agriculture, transport, technological disasters, electromagnetic radiation, noise.

1.2. Environmental impact mechanisms on human health

The environment has a multifaceted effect on human health, affecting various body systems and contributing to the development of various diseases. The mechanisms of exposure can be classified as follows:

Direct impact: Direct contact with harmful substances or factors (for example, chemical poisoning, ultraviolet radiation damage).
Indirect impact: Change in living conditions, leading to a deterioration in health (for example, air pollution, leading to respiratory diseases, a lack of pure water, leading to infectious diseases).
Cumulative impact: The accumulation of harmful substances in the body over time leading to the development of chronic diseases (for example, the accumulation of heavy metals, leading to neurological disorders).
Synergetic impact: The combined effects of several factors, enhancing their negative impact on health (for example, smoking and air pollution that enhance the risk of lung cancer).

At the cellular level, environmental exposure can lead to:

Oxidizing stress: Violation of the balance between the formation of free radicals and antioxidant protection, leading to cell damage.
Inflammation: Activation of the immune system in response to the effects of harmful substances, leading to chronic diseases.
DNA damage: Violation of the structure of DNA, leading to mutations and cancer.
Epigenetic changes: Changing the expression of genes without changing the sequence of DNA, leading to hereditary diseases.

1.3. Key environmental factors that affect life expectancy

Some environmental factors have the most significant impact on life expectancy:

Air pollution: Air pollution with solid particles (PM2.5 and PM10), ozone, nitrogen and sulfur oxides are one of the main risk factors for premature death. It is associated with respiratory diseases, cardiovascular diseases, lung cancer and other diseases.
Water quality: The lack of pure water and water pollution with pathogenic microorganisms and chemicals leads to infectious diseases, poisoning and other health problems.
Climate: Extreme temperatures (heat and cold), natural disasters (floods, hurricanes, droughts), climate change increase the risk of mortality.
Radiation: The impact of high levels of radiation (for example, from nuclear accidents or radon) increases the risk of cancer.
Noise: Long-term impact of noise (for example, from transport, industry) is associated with cardiovascular diseases, sleep disturbances and mental disorders.
Toxic substances: The effect of toxic substances (for example, heavy metals, pesticides, industrial chemicals) can lead to various diseases, including cancer, neurological disorders and reproductive problems.
Green spaces: The lack of green spaces in urban areas is associated with an increased level of stress, a decrease in physical activity and an increased risk of diseases.
Socio-economic factors: The low level of income, poor housing conditions, the lack of access to medical services also have a significant impact on life expectancy.

Chapter 2: Geographical features and longevity: the study of regions with a high life expectancy

2.1. “Blue zones”: Review of regions with exceptional longevity

“Blue zones” are the regions of the world where people live much longer than the average on the planet, and at the same time retain health and activity in old age. Studies of these zones allow you to identify factors that contribute to longevity. The main “blue zones” include:

Okinava, Japan: Okinava residents are characterized by healthy nutrition (mainly vegetable), high physical activity and strong social ties. They also practice the concept of “Ikigai” – the meaning of life.
Sardinia, Italy: Residents of Sardinia, especially in mountainous areas, have a high concentration of male centenarians. Their diet is rich in vegetable products, whole grain products and sheep’s milk. They also lead an active lifestyle and have close family ties.
Ikaria, Greece: Residents of Ikaria adhere to the Mediterranean diet, rich in vegetables, fruits, olive oil and fish. They also lead an active lifestyle, walk a lot and have strong social ties.
No one, Costa-Rika: Residents of Nico live in conditions of warm climate, engage in physical labor (for example, farming), adhere to a plant diet and have strong family ties. They also have a positive attitude to life.
Lomb Linda, California, USA (seventh -day Adventists): Seventh -day adventists living in Lomb Linda adhere to a vegetarian diet, do not smoke and do not drink alcohol, lead an active lifestyle and have strong social ties.

2.2. Comparative analysis of environmental factors in “blue zones”

A comparative analysis of environmental factors in the “blue zones” allows us to identify general patterns that contribute to longevity:

Pure air and water: In the “blue zones”, as a rule, there is a low level of air and water pollution. This is due to the fact that these regions are often located in rural areas or in areas with a low level of industrial development.
Warm climate: Most of the “blue zones” are located in regions with a moderate or warm climate, which contributes to an active lifestyle in the open air and reduces the risk of hypothermia.
Mountain relief: In some “blue zones”, such as Sardinia and Ikaria, a mountainous relief prevails, which stimulates physical activity.
Rich vegetation: In the “blue zones” rich in vegetation is often found, which provides clean air and access to fresh fruits and vegetables.
Low stress: In the “blue zones” a low level of stress is often observed, which is associated with a slow pace of life, strong social connections and a positive attitude to life.

2.3. Examples of other regions with a high life expectancy and their environmental features

In addition to the “blue zones”, there are other regions of the world with a high life expectancy that also deserve attention:

Switzerland: Switzerland occupies one of the first places in the world in terms of life expectancy. This is due to a high level of life, a developed healthcare system, clean air and water, as well as healthy nutrition.
Japan (in general): Japan as a whole is distinguished by a high life expectancy, especially among women. This is due to the traditional Japanese diet, rich in fish, vegetables and soy, as well as high physical activity and a developed healthcare system.
Singapore: Singapore also has a high life expectancy. This is due to a high standard of living, a developed healthcare system, strict control over environmental pollution and a healthy lifestyle.
