People who wake up at night with an urge to go to the toilet may need to cut back on salt in their diets.
This is according to doctors in Japan.
The problem ‑ called Nocturia ‑ which mainly affects the over‑60s, leads to disrupted sleep and can significantly affect people's lives.
In a study of more than 300 volunteers, researchers found that reduced salt intake led people to urinate less.
They followed patients who had a high salt intake and sleeping problems for three months, after giving them advice to cut back on salt in their diet.
On average, trips to the loo fell from more than twice a night to just one.
This happened at night as well as during the day, and their quality of life also improved.
