Talking during sleep is known in the medical field as somniloquy and it is quite common and is not usually a cause or a result of medical or mental health problems. It is a type of parasomnia, an abnormal behavior that occurs during sleep. The range that this occurs varies drastically from occurring very infrequently to multiple episodes every night. It can also range from very quiet and indecipherable to loud, even angry, yelling. Most sleep-talkers have no recollection that they have spoken during their sleep. Talking during sleep usually occurs on its own with no associated medical conditions and is quite harmless. However, the fact that your boyfriend never feels well rested and has frequent awakenings suggest that something else is going on besides just talking in his sleep. This could be caused by many things such as insomnia
, stress, sleep apnea
, medications, etc and it is important that your boyfriend make an appointment with his primary care doctor
to discuss his symptoms and seek appropriate treatment. If your boyfriend's sleep talking is keeping you from getting adequate rest than you should invest in ear plugs or sleep in a different room. Most people need 8 hours of uninterrupted sleep a night.
