A recent study has found that women who work night shifts are more likely to suffer from moderate or severe asthma compared to those who work during the day. This research, published in the journal ERJ Open Research, involved over 270,000 participants and highlighted a significant health concern for female night shift workers.
The lead researcher, Dr. Robert Maidstone from the University of Manchester, stated, “Our findings show that women who only work night shifts are about 50% more likely to experience moderate or severe asthma than those who work only during the daytime.” Interestingly, this increased risk was not seen in men, suggesting that the link between shift work and asthma may be unique to women.
The study analyzed data from the UK Biobank, which included a wide range of working individuals. Out of the participants, 5.3% had asthma, with 1.9% suffering from moderate or severe forms of the condition. Moderate or severe asthma means that these individuals used an asthma-preventer inhaler along with other asthma treatments, such as oral steroids.
Dr. Maidstone noted that asthma disproportionately affects women, who typically experience more severe cases and face higher rates of hospitalization and death from the condition. He pointed out possible reasons for the increased risk among night shift workers, such as disruptions to the body’s natural clock and changes in hormone levels.
In particular, the study found that postmenopausal women who worked night shifts and did not use hormone replacement therapy (HRT) had nearly double the risk of moderate to severe asthma compared to their day-working counterparts. Dr. Maidstone suggested that HRT might offer some protection against asthma for night shift workers, but more research is needed to confirm this.
Professor Florence Schleich, an expert in respiratory health based in Belgium, commented on these findings, stating that while the research indicates a potential risk factor, more studies are necessary to understand the relationship fully. She emphasized the importance of continuous investigation to help women who work shifts reduce their asthma risk.
The study’s results are crucial for understanding the unique health challenges faced by women in the workforce, particularly those in night shift positions. As shift work becomes increasingly common in various industries, addressing these health concerns will be vital for ensuring the well-being of female employees.
