According to a study of 32 healthy women who were subject to repeated sleep disturbances over a period of 1 week, it was found that women whose sleep was disrupted showed an increase in spontaneous pain and decrease in pain inhibition. This effect was not seen in women who were sleep deprived or who slept a full night. The results suggest that people who are repeatedly awakened from sleep may become more susceptible to pain.
