Dairy consumption may cause nightmares and poor sleep

A new study suggests that consuming too much dairy may lead to nightmares and poor sleep quality. Researchers found a strong correlation between lactose intolerance and more frequent, severe nightmares. Gastrointestinal discomfort during sleep, potentially caused by dairy, may influence dream experiences. The study's lead author suggests that dietary changes for those with food sensitivities could improve sleep. This research may explain why people often blame dairy for bad dreams.
