Abstract:
A shortage of oxygen in your blood can translate into low oxygen in your tissues when
enough blood is not being carried to your tissues to meet the body's quota. Confined
spaces are known to be linked with low environmental oxygen and/or the accumulation
of toxic gases. Atmospheres that have an increased amount of carbon dioxide in
combination with low oxygen can cause death suddenly. Scenarios such as these
include closed atmospheres where oxygen is used up and carbon dioxide builds up.
People can die suddenly in environments with abnormal composition. Supposedly about
60 per cent of our required air circulation came from areas we didn't know about; but in
highly efficient, airtight homes, reliance on incidental air leakage through leaky walls
and windows no longer provides a safety net. So, what is the importance of ventilation?
Well, poor ventilation can have serious consequences. Worse again, high levels of
relative humidity affect the concentration of volatile organic compounds in the home
and prolonged exposure to these compound leads to terrible health conditions such as
eczema, nervous system damage and cancer. So we do need ventilation, and good
ventilation. Better air quality means a healthier environment.
