The Environmental Sensitivities Cycle
Increasingly, scientists are identifying a two-phase process leading to environmental sensitivities.

The onset of the illness takes place either after chronic low-level exposure to contaminants or after one high-level exposure to a chemical substance, electromagnetic radiation, or a biological agent. The factors involved are called initiating agents (Table 1).

- Volatile organic compounds (VOCs: solvents, perfumes, formaldehyde and other petrochemical products, exhaust gases from vehicles)
- Electromagnetic radiation and/or fields
These agents can emanate from the structure of a building, some types of furniture and equipment, neighbourhood surroundings, cleaning products, etc. There are also environmental factors which can worsen the symptoms of environmental sensitivities such as lighting, humidity, heat, cold and noise.
The initiating agents cause a loss of tolerance in affected people, thereby triggering the environmental sensitivities cycle.

Once environmental sensitivities are triggered, people who are affected often react to several other http://www.porttalbotwheelers.co.uk/?kisko=daily-weekly-cosa-significa-nella-opzioni-binarie&5c3=3e triggering agents (Table 1), even at very low doses or concentrations. A series of metabolic reactions then brings about many follow symptoms (figure 1), resulting in a chronic condition.
