When I first came to the States I could not work out why everyone was getting sick all the time and staying sick for long periods of time. A cold that would last for weeks with people running down to their doctors being diagnosed with pneumonia, having X rays taken of their chest. Doctors giving out antibiotics like they were candy. A running nose that would just not go away.
At first it was just an observation then I started asking questions and found people that would get small nose bleeds or bleeding when they blew their nose. Itchy skin was another condition that seemed prevalent in Dallas with many different moisture being applied to various parts of the body.
People getting headaches and migraines as they increased the thermostats in their homes higher and higher and not feeling the benefits, only resulting in a higher gas bill every month.
I spent many years in the UK working within Council properties (government owned rented accommodation) dealing with mold and ventilation problems caused in the main by fuel poverty, people that could not afford to pay for electric or gas so did not properly heat or ventilate their homes which lead to mold and health issues and sometime building structural problems.
I built a small website just for a certain area in West London which is www.ealingmold.co.uk. I was amazed in this affluent area how many people and homes were suffering from the same issues as the fuel poverty were. Much of these problems were due to high humidity levels.
Much of health problems in Dallas could be helped if we did not live in such low humidity. A home where ever it is should be kept at around 30% - 60% relative humidity for us humans to live comfortably.
I believe the driest place in the world with the lowest humidity is the Atacama desert of South America which can have a humidity level as low as 5% -10%. Death Valley has around 10% - 25% humidity. After much research we, here is Dallas, within our homes are living within a humidity level that is below 30% most of the time. This is just unhealthy for us and can cause many of the effects I have reported here. I am no doctor so just Google "living in a low humidity environment" to find out more.
It is also a fact that if you can raise the humidity higher than 30% RH you will feel the benefits in your heating bill because at 72 degrees F a higher humidity will actually feel warmer that 75 degrees F at a lower humidity.
The EPA reports that indoor air quality can be up to 100 times more polluted than outside air resulting in unhealthy living conditions and many other associated health risks. The American Lung Association reports that poor indoor air quality is among the top five environmental risks to public health. Poor indoor air quality and “sick building syndrome” are bi-products of the world’s attempts to be more energy efficient. We seal up our windows and doors and utilize special building products for energy efficiency. An unforeseen circumstance is that our homes, schools, and workplaces have very little, to no fresh air. Allergens, chemicals and cleaning products, pets, musty spaces, and mold can all contribute to poor air quality.
