Based on conversations with friends and associates I have found the relationship between human health and jet noise difficult to communicate. Based on several studies the human body's negative connection to jet noise is made with the stress hormone cortisol as secreted by the adrenal glands. Under normal circumstances cortisol is responsible for the 'fight or flight' response. A problem develops when this hormone is stimulated over a period of time. An instantaneous secretion of cortisol protects humans from accidents and disaster. A prolonged secretion causes stress related damage and disease.
For example:
· Impaired cognitive performance
· Suppressed thyroid function
· Blood sugar imbalances such as hyperglycemia
· Decreased bone density
· Decrease in muscle tissue
· Higher blood pressure
· Lowered immunity and inflammatory responses in the body, slowed wound healing, and other health consequences
· Increased abdominal fat, which is associated with a greater amount of health problems than fat deposited in other areas of the body. Some of the health problems associated with increased stomach fat are heart attacks, strokes, the development of metabolic syndrome, higher levels of "bad" cholesterol (LDL) and lower levels of "good" cholesterol (HDL), which can lead to other health problems!
Conditions listed above are epidemic in our society. The relationship of these conditions is well know.

I tend a hobby farm and use power tools. Part of my work [aka play] process involves protection of life, limb and hearing. I use two layers of hearing protection, both OSHA approved. First I install foam plugs followed by muffs. This procedure negates most sounds to nearly zero. This procedure did not reduce jet over flight noise. I believe sound waves created by jets enter the body differently and affect the organs and adrenal glands in a more fundamental way.
This is serious and dangerous to us humans and presumably to other earth creatures.

The Purpose of This Blog
The purpose of this blog is to discuss and share information related to the harm perpetrated by the aviation industry. Over the past two years I have discovered a relationship between the onset of high blood pressure and the substantial increase of jet over flights. Further research indicates a direct relationship between over flights and many modern epidemics.
I used to be a frequent flier as a commuter between Southern California and Southeastern Kentucky. I always appreciated the quiet upon arriving at my rural Kentucky home. That quiet has been eliminated by the aviation industry in less than two years.
I tried to obtain information about the increase in flights from the various arms of the FAA. It didn't take long to determine the governmental side of this industry would offer nothing to a concerned citizen, except institutional lying. I was told several times 'there are no flights over your area'. I contacted a member of the House of Representatives to see if his office could determine why there was such a significant increase in flights. His office was told the same lie. There are often 2000 flights per day over my home.
The studies I have found regarding this matter are tedious and laced with technical terms. My professional training and experience has helped me understand the significance of the aviation industry to our health.
One European study of 5,000 participant found an increase of blood pressure under very normal circumstances. If you are asleep at a sound level equal to a quiet conversation in a library and a jet overflight is the loudness of a baby's breath your blood pressure will increase an average of 14%. Blood pressure elevations increase as the sound levels of over flights increase.
The health issues are many and significant. For example, a recent study from Stanford University indicates a 197% increase in breast cancer for citizens under flight paths.
Other issues include air pollution and the destruction of polar ice. I will post links to these and other studies in future posts.
