Night-time trips to the loo cut our productivity by a quarter, research shows Those with nocturia lose 24% productivity at work Sufferers have to wake up once or more at night to urinate People who get up to go to the toilet in the middle of the night are less productive in work than those who sleep throughout, research suggests. Nocturia - where a person wakes up once or more in a night to urinate - leads to "notable work productivity loss," a study presented to the European Association of Urology congress in Milan claims. Researchers examined 261 women and 385 men with the condition and gave them a standardised work productivity and activity impairment questionnaire Sufferers of nocturia have to wake up during the night to urinate causing them to lose productivity at work It examines the effect of health problems on a person's ability to work and perform regular activities. They found that nocturia was found to reduce work productivity by 24% - greater than the productivity loss shown by people with asthma or chronic obstructive pulmonary disease. Philip Van Kerrebroeck, professor of urology at the University of Maastricht in the Netherlands, said: 'Nocturia is a common problem affecting around a third of adults, but its burden is underestimated and it is often dismissed as being less serious than other chronic conditions in terms of impact on quality of life and societal costs. A study by the University of Maastricht shows that those with the condition lose 24 per cent productivity, more than those with asthma or lung conditions These data show that nocturia negatively affects both sleep and daytime performance and its impact on work productivity is in line with many other chronic conditions. Patients with nocturia should seek specific treatment for this debilitating condition.
