6 EFFECTS OF POOR VENTILATION – Ventilation is the circulation of fresh air in a house or an enclosed space. The movement of fresh air in a house is facilitated by good ventilation. Poor ventilation occurs when the systems of controlling airflow inside the environs of a house have totally failed. Indoor air quality is determined by how much fresh air is entering the building and how effective is contaminated air exiting the house. People who stay in enclosed houses are mostly ignorant of the health conditions that come with it.
The following are the consequences of poor ventilation on the psychological and physical health of the occupants:
Poor Ventilation leads to low level of oxygen in the house.
Poor ventilation leads to a buildup of carbon dioxide and depletion of oxygen. Depletion of oxygen and buildup of carbon dioxide may result in shortness of breath, fatigue, and severe headaches.
Enhances the spread of transmittable airborne diseases and viruses.
Airborne diseases become transmitted into the air when a person talks, sneezes or coughs in an enclosed environment. Communicable Pathogens can move from one person to another in a house with poor air quality. Airborne diseases include meningitis, anthrax, chicken pox, avian influenza, measles, monkeypox, smallpox, tuberculosis, SARS etc.
Enhances stress build up to the occupants of the house.
Poor quality indoor air may lead to psychological shortcomings such as stress and discomfort. Psychological distress poses a very serious risk to the health of an individual.
Poor Ventilation Causes sinus, allergies, and nausea.
Irritating odor and stuffiness caused by congestion in the poorly ventilated house cause allergies, hypersensitivity, dizziness, and nausea.
Leads to serious health conditions like eczema, nervous system damage, and cancer.
A high level of humidity in a house leads to build up of volatile organic compounds in the house. The prolonged exposure to these volatile compounds is cancerous and may even lead to a damage of the nervous system.
Poor Ventilation Causes sick building syndrome (SBS).
Symptoms of SBS include irritation of the eyes, nose and the throat, fatigue, and susceptibility to flu. They occur when one is indoors and tend to disappear when one leaves the poorly ventilated building. This is why some people tend to have the flu when they enter a building, but if they stay away from it they recover very fast.
Therefore, better indoor air quality creates a healthier environment to reside in. Poor ventilation contributes to condensation and mold formation. Apart from damaging the walls and fabrics of the house, mold, mildew, and mites they can increase which are dangerous to the human respiratory system, circulation system, and mental faculty.
