It is accepted that the Common cold is caused by viruses such as the rhinovirus and can be transmitted from one infected individual to the other. The cold viruses are easily spread by one human coughing or sneezing in the air surrounding a healthy subject.

According to Wikipedia, Rhinovirus infection proliferates in temperatures between 33-35 degrees Celsius (91 to 95) the temperature found in the nose.

Dr Fiset after being exposed to a child suffering from a cold's drect cough, developed symptoms of the common cold such as a sore throat.

She elaborated the premise that if she could lower the temperature in her mouth and nose by Breathing by her open mouth, the virus might not develop. During the first day, she breath with her mouth slightly opened letting in cooler air (room temperature air is normally around 22 degrees Celsius) and did not develop a common cold the next day.

Dr Fiset added to her Breathing Technique drinking a lot of cold water and gargling with cold water. She based her behavior on the premise that it is accepted knowledge that a person starting a cold needs to hydrate herself. The gargling aimed at removing the virus from her throat.

Dr Fiset then filed a provisional patent for her breathing technique and recruited volunteers to practice her breathing methods the moment they felt a cold coming. She wanted to test if other people could get similar results, that is to say stop a common cold from developing by breathing through their mouth the minute they felt it in their throat.

To do her breathing technique, she opened her mouth creating a space of one quarter to one half of an inch between her upper and lower lips (when she was in public not to stand out). She breathe through her mouth widely opened when alone. Her breathing rate was not modified. She did this breathing technique many times during the first day she felt the cold in her throat.

According to Webmd, between lost work and doctor visits, and cold medicine, the common cold costs the U.S. economy about $40 billion a year.

Further research with double blind controlled studies need to be done. Dr Fiset also questions if by having a shorter encounter with the rhinovirus a person might not develop as much antibodies as if she had developed the full course of the common cold.

The power of using Dr Fiset's breathing method to stop a cold from developing is that it is natural and theoretically can succeed against any virus causing the common cold, contrary to potent retroviruses that also carry important side effects.

Antiviral drugs cost a lot of money and can cause resistant viruses. Furthermore, some cold viruses would not be affected by antiviral drugs.

Dr Fiset's breathing technique is free. It also changes the environment in a natural way making it unsuitable for common cold viruses to develop fully.

There will always be viruses that give common cold. By developing her breathing technique, Dr Fiset is merely suggesting that an acute cold can be stopped, diminished or alleviated naturally.

Dr Fiset voices her concern that if her breathing method to stop the cold from developing spreads, a new generation of viruses that give a cold might develop, one that can thrive at lower temperature.
