Even reducing your intake by just 2g a day could make all the difference, and give you a deserved full night's sleep, say researchers from Nagasaki University in Japan.
They noticed a connection between nocturia and salt intake when they surveyed a group of 321 men and women, whose lifestyles and diets they monitored for 12 weeks.
Most were consuming around 10.7g of salt a day, and they were averaging more than two trips to the bathroom at night—but reducing the intake by 2g also translated into one fewer trip. Daytime visits to the toilet also went down.
Conversely, those who increased their salt intake during the study also had to visit the bathroom more frequently at night.
Nocturia becomes more of a problem once we reach the age of 60 anyway, says lead researcher Dr Matsuo Tomohiro, but we can help the problem by consuming less salt every day
