Waking up several times in the middle of the night to urinate could be symptomatic of an unhealthy diet.
This condition, called nocturia, is most common in people over the age of 60.
A recent study suggests that an over-consumption of salt could be the main cause of this condition.
Several researchers of Nagasaki University in Japan, a country with a high percentage of people consuming an excessive amount of salt on a daily basis, conducted a study in which they introduced a low salt diet to 321 participants.
Of the total, 223 participants saw a significant drop in both daytime and nighttime urination.
The researchers also emphasised that people who urinated less frequently at night benefited from a better quality of life.
Though the study was a success, the lead researcher, Dr. Matsuo Tomohiro, told AFP that more research was still needed to further study the relationship between a high salt diet and nocturia.
"This work holds out the possibility that a simply dietary modification might significantly improve the quality of life for many people," he said.
