Around One-Third of Japanese Men Affected by Nocturia? Nationwide Survey Reveals | Integri News

New survey results on men's health in Japan have been announced. It has been found that about one-third of men aged 40 and over experience "nocturia," the condition of waking up to use the toilet two or more times a night.

These findings are based on data from "JaCS 2023," a nationwide online survey conducted in 2023. In this survey, participants answered 48 questions about urinary symptoms and daily life. The subjects were 6,210 participants aged between 20 and 99.

Nocturia is a condition in which waking up to use the toilet many times at night disrupts sleep. Because sleep becomes shallow, it can also lead to daytime fatigue and reduced concentration. The condition tends to increase with age and can be a familiar concern, particularly for middle-aged and older men.

Experts say that if nocturia is a concern, it is important to consult a medical institution early. They also note that paying attention to daily fluid intake and drinks before bedtime may help improve symptoms. This survey is considered an important resource for deepening understanding of urinary health among Japanese people.
