Human Health

Constant Climatic changes pose a great challenge to Human Health. Even though toxins and disease pathogens are a threat to health, Climate change may cause health effects that are potentially harmful. These threats include impacts from heat waves, air pollution that causes ailments, severe storms and many infectious diseases.

Assessing the glaring effects of climate change to human health should realistically include setting up a capacity to manage the unpredictable climate conditions. Due to the health risks occasioned by the climatic change, there is needed to set up and run a vibrant public health infrastructure.

Since we live in a global village, increased of risks associated with diseases emanating from other countries should be considered. Climate change has made poor countries suffer greatly. Due to global trade that requires a lot of travelling between different countries, diseases are bound to flare-up in any part of the world. Extreme climatic conditions such as severe draught and storms also undermine the public health infrastructure that is in place.

It is worthy noting that;

• There has been a significant increase recorded in illness and death that has been caused by extreme heat waves. There is also death caused by extreme cold weather.

• It will be difficult to protect human health because set air quality standards won’t be met due to Warming of the environment.

• Weather conditions that are extreme have caused physical and psychological problems to mankind. This has led to stress and depression related ailments.

• There is a marked increase in diseases that are transmitted by water, food and insects.

• Due to rising carbon dioxide concentration and temperatures, production of pollen is increased hence a number of plants with high rate of allergenic pollen have a prolonged pollen season. This presents a health risk to human beings.

Environmental contamination and emergence of infectious diseases has caused public health concerns world wide. Health threats have also affected the relationship between human beings with physical, biological and chemical conditions of our natural environments. » Read more: Human Health

Five Potential Health Consequences of Reverse Osmosis Systems

September 25th, 2010

Water quality has been on pollution and removing contaminants to a level considered safe for drinking water. Now there is also concern that we may be taking out essential nutrients needed for our health. As early as 1980, the World Health Organization(WHO) began to notice some effects on the populations that were using desalinated water. They concluded then that completely demineralised water has a “definite adverse influence on the animal and human organism.”

In 2005, WHO presented a publication titled: Nutrients in Drinking Water. One whole chapter was devoted to the health risks of consuming water that had the minerals removed. All methods of artificially producing demineralised water were discussed, including the home use of reverse osmosis systems.

The WHO publication discussed Five possible health consequences of consuming water with a low mineral content:

There is a negative effect on water and mineral homeostasis mechanisms of the body. It causes an increase in urine output that, in turn, causes an electrolyte imbalance.
No intake of calcium and magnesium from low-mineral water is associated with an increase in death from cardiovascular disease, a higher risk of fracture in children, some neuro-degenerative diseases , low birth weight of babies and even some types of cancer.
Intake of other essential elements and micro elements is reduced in low mineral water. It is needed since, the modern diet may not be an adequate. Even the low intake of the element with drinking water is important. This is because the elements are more easily absorbed from water than from food.
Loss of calcium, magnesium and other essential elements can be as high as 60%, or even more, when preparing food with low mineral water. Since the diet may not provide adequate amounts of these minerals, further reductions may cause severe deficiencies of these nutrients.
There is a possible increase in intake of toxic metals due to leaching from pipes or storage tanks. » Read more: Five Potential Health Consequences of Reverse Osmosis Systems
