Scottish bar workers "substantially" healthier after smoking ban says study
The respiratory health of bar workers in Scotland has improved "substantially" since the country launched its smoking ban, say scientists.
The improvement was noticeable in tests taken just two months after the ban came into effect, said the Ninewells Hospital and Medical School research team.
The team examined 105 bar workers for the study, using a range of indicators of respiratory disorder, such as coughing, shortness of breath, painful throats and sneezing.
The number of bar workers with discernable symptoms fell by almost a third during the study, from 79.2 per cent at the beginning to 46.8 per cent two months after the ban.
They were also found to have improved lung functioning and less detectable nicotine in their bodies. Their throats were less inflamed and they reported a higher quality of life.
Secondhand smoke is a major worldwide health issue, with studies linking it to heart disease and lung cancer and US research linking it to premature death.
