| | |
Adults and children with breathing difficulties may be interested to know that decommissioned mines maintain a microclimate that is virtually free of allergens and dust.
The cool air inhaled into the lungs is warmed to body temperature. Because warm air is able to absorb more water, the mucous membranes of the lungs shrink, thus clearing the airways.
According to air measurements there is a constant temperature of approx.
9 °C, a relative humidity of approx 95% and a very low absolute humidity.
