Positive stress occurs when there is more air being provided than tired, and prevails to decrease the infiltration of outside contaminants. All-natural ventilation is an essential consider helping to reduce the spread of air-borne diseases and health problems such as tuberculosis, the common cold, influenza and meningitis. Natural air flow is the most convenient and easiest form of cooling and heating as it calls for little to no maintenance, is frequently totally free or at the very least low-cost as can be supplied by something as easy as opening doors, home windows, or usage of ceiling followers are all methods to increase natural ventilation and as a result lower the risk of air-borne transmission.
