21 Aug 2018 --- The need to urinate is by far the most common cause of sleep disruption in older men, a survey by wellness company Lycored has shown. The research also reveals high demand for natural supplements to address the problem. The survey included 313 men over the age of 50 (163 in the UK and 150 in the US). Almost all (96 percent) say sleep quality was either important or very important to their health.
