Sodium and sleeping through the night

A group of researchers from Nagasaki University, led by Dr. Matsuo Tomohior has studied salt intake in a group of 321 men and women who had a high salt intake and had problems sleeping. This was the first study to measure how salt intake affects the frequency of going to the bathroom so they need to confirm the work with larger studies. Nocturia or nighttime peeing was reduced with lower salt intake. The need to pee at night affects most people over the age of 60 and the lack of sleep can lead to other problems such as stress, irritability or tiredness. 223 members of the group reduced their salt intake from 10.7 gm per day to 8.0 gm/day. Night time frequency of urination dropped from 2.3 times to 1.4 times. The researchers also found that daytime urination was reduced when salt int he diet was reduced.
