The smog phenomenon and its health consequences seem to be nowadays a real problem for many societies, including Poland. In addition, the question arises as to what impact it may have on urban planning and architectural design. Scientists believe that there are only three methods to avoid the dangerous smog pollution: trying to stay indoors during smog alerts, avoiding outdoor exercise and using special masks. However, using masks during exercising is unhealthy due to the reduction of the body’s oxygenation. Special attention should be paid to the location of open sports areas for young citizens. Air-conditioned sports halls would be the best option for those who want to be physically active during smog alerts.
