If you find yourself waking up in the middle of the night to use the restroom, researchers say it may be time to cut some salt from your diet.
According to recent research presented at the European Society of Urology congress in London, the need to pee at night is related the amount of salt in your diet.
A group of researchers from Nagasaki University in Japan found that nighttime peeing, or nocturia, was significantly reduced when the amount of salt in a person's diet was also significantly reduced.
The researchers, led by Dr. Matsuo Tomohiro, studied more than 300 men and women who had high salt intake and problems sleeping through the night. The participants were instructed to reduce salt consumption, monitored for 12 weeks. Any salt that was consumed was measured and recorded.
More than 200 participants cut back how much salt they ate from nearly 11-grams per day to about 8-grams per day resulting in nightly visits to the bathroom dropping from about two times per night to one. A group of more than 90 participants increased how much salt they ate and their trips to the bathroom increased from about two times to nearly three times each night.
"This is the first study to measure how salt intake affects the frequency of going to the bathroom, so we need to confirm the work with larger studies," Dr. Tomohiro said. "Nighttime urination is a real problem for many people, especially as they get older. This work holds out the possibility that a simply dietary modification might significantly improve the quality of life for many people."
Researchers also found that frequent daytime urination was also reduced when people cut salt from their diets.
