Have you ever wondered what’s in the air? Average people spend more than 90% of their lives indoor, with air that has been mechanically ventilated. The ventilation system in such places like hospitals protects people from airborne infections and the outdoor bacteria. Not only that, mechanical ventilation system filters, heats, and air-conditions the outdoor air which keeps the suitable environment for us; however, the mechanical ventilation also keeps the good microbes, which strengthens our health, from entering into our indoor environment.
A recent project states that there was a decrease in the microbial diversity in the ventilated indoor air in their research, but less microbial diversity is not necessarily good.Therefore they suggested that limiting certain microbes to enter our indoor environment and promoting the presence of the good microbes indoors could improve our health.
Another research shows that it is less likely to be prone to asthma, and protected from asthma. This shows that the exposure to the microbes in the environment can definitely benefit human health.
Because a lot of microbes are known to be harmful to human health, it is crucial, as mentioned before, to keep the micro-diversity under control, with the presence of good microbes promoted, and harmful microbes inhibited.
