Does Health Promotion Harm the Environment?

“Health promotion involves social and environmental interventions designed to benefit and protect health. It often harmfully impacts the environment through air and water pollution, medical waste, greenhouse gas emissions, and other externalities. We consider potential conflicts between health promotion and environmental protection and why and how the healthcare industry might promote health while protecting environments.

After probing conflicts between promoting health and protecting the environment we highlight the essential role that environmental resources play in health and healthcare to show that environmental protection is a form of health promotion. We then explore relationships between three radical forms of health promotion and the environment: (1) lowering the human birth rate; (2) transforming the food system; and (3) genetically modifying mosquitos.

We conclude that healthcare and other industries and their institutions and leaders have responsibilities to re-consider and modify their priorities, policies, and practices.”

Copper Kills Superbugs

In China, it was called “qi,” the symbol for health. In Egypt it was called “ankh,” the symbol for eternal life. For the Phoenicians, the reference was synonymous with Aphrodite—the goddess of love and beauty.

These ancient civilizations were referring to copper, a material that cultures across the globe have recognized as vital to our health for more than 5,o00 years. When influenzas, bacteria like E. coli, superbugs like MRSA, or even coronaviruses land on most hard surfaces, they can live for up to four to five days. But when they land on copper, and copper alloys like brass, they die within minutes. “We’ve seen viruses just blow apart,” says Bill Keevil, professor of environmental healthcare at the University of Southampton. “They land on copper and it just degrades them.”

Low-Cost Breathing Ventilators

The high price of machine ventilators forces many hospitals in the poorest regions of the world to rely on a simple solution known as an Ambu Bag that requires constant manual pressure in order to get oxygen to the lungs.The Umbulizer is a mechanically powered version of the Ambu Bag.

Biological Pest Control: Bat Towers

At the turn of the twentieth century, Dr. Charles A. Campbell, a physician and former city bacteriologist in San Antonio, Texas, began the first experiments with attracting bats to artificial roosts. Although he had the highest regard for bats, the motive behind his experiments was not that he thought bats needed homes. The real reason was to find a way to control a disease that caused millions of deaths throughout the world each year: malaria. In his native Texas, mosquitoes and disease rendered countless acres of fertile land uninhabitable, and Campbell, who treated victims of malaria, knew the suffering it caused. [Read more…]

Non-Electric Hearing Aids Outperform Modern Devices

Most people with hearing problems are not using hearing aids, mainly because the electronic devices often do not provide enough benefit. Research shows that non-electric hearing aids from earlier centuries are performing significantly better.

Low-tech Baby Care

Kangaroo Mother Care (KMC) is the brainchild of Colombian pediatrician Edgar Rey, who introduced it to the Instituto Materno Infantil in 1978. It was an idea born out of desperation. The institute served the city’s poorest—those who lived crammed in the rickety makeshift dwellings in the foothills of the surrounding mountains. At the time, this was the biggest neonatal unit in all of Colombia, responsible for delivering 30,000 babies a year.

Overcrowding was so bad that three babies would have to share an incubator at a time and the rate of cross-infection was high. Death rates were spiraling, and so too was the level of abandonment. Many young, impoverished mothers who never even got to touch their babies found it easier just to take off.

Scouting around for a solution to these problems, Rey happened upon a paper on the physiology of the kangaroo. It mentioned how at birth, kangaroos are bald and roughly the size of a peanut—very immature, just like a human pre-term baby. Once in its mother’s pouch, the kangaroo receives thermal regulation from the direct skin-to-skin contact afforded by its lack of hair. It then latches onto its mother’s nipple, where it remains until it has grown to roughly a quarter of its mother’s weight, when it is finally ready to emerge into the world.

This struck a chord with Rey. He went back to the institute and decided to test it out. He trained mothers of premature babies to carry them just as kangaroos do. Working alongside his colleague Hector Martinez, he taught them the importance of breastfeeding and discharged them just as soon as their babies were able. The results were remarkable. Death rates and infection levels dropped immediately. Overcrowding was reduced because hospital stays were much shorter, incubators were freed up, and the number of abandoned babies fell.
