Sleep talking, also known as somniloquy, is a sleep disorder characterized by vocalizations or talking during sleep. It is classified as a parasomnia, which is an abnormal behavior or occurrence during sleep. Sleep talking can range from simple sounds, mumbles or nonsensical utterances, to coherent and understandable conversations.

Causes of Sleep Talking:

Sleep talking can be caused by various factors, including:

  • Stress and anxiety: Emotional distress and anxiety may lead to sleep talking.
  • Sleep deprivation: Lack of sufficient sleep or poor sleep quality may contribute to sleep talking.
  • Alcohol or drug use: Substance abuse or certain medications can increase the likelihood of sleep talking.
  • Fever or illness: Sleep talking can occur during periods of illness or high body temperature.
  • Sleep disorders: Conditions such as sleep apnea, sleepwalking, or night terrors can be associated with sleep talking.


In most cases, treatment for sleep talking is not necessary. However, addressing any underlying causes or sleep disorders, as well as practicing healthy sleep habits, can help reduce the frequency or intensity of sleep talking episodes. In some instances, therapy or medication may be recommended to manage sleep talking associated with other sleep disorders.
