According to WebMd, getting more exercise, avoiding caffeinated beverages, increasing REM sleep and keeping a sleep journal are all ways to help avoid talking while sleeping. Decreasing stress levels and focusing on stronger REM sleep also decreases the likelihood of sleep talking.
Stress is common cause of restless sleep, which contributes to sleep talking, according to WebMd.
An easy way to monitor sleep patterns and ensure the recommended amount of sleep is to keep a sleep journal. Recording sleeping hours, bed times and wake times gives insight into basic sleep patterns.
Sleep talking may be rooted in psychological issues, so WebMd recommends seeking help in analyzing the fundamental causes if the condition persists.
The National Sleep Foundation suggests avoiding heavy meals before bedtime to promote sleep health and adequate duration of REM sleep. This could reduce the likelihood of sleep talking. However, there is no cure for the condition, nor are its causes fully understood.
Sleep apnea is a possible cause, as it disrupts normal sleep patterns and restricts REM sleep. In individuals age 25 or older, a medical or psychiatric condition such as confusional arousal or nocturnal seizures may stimulate or exacerbate sleep talking, and treatment may alleviate it.
