Eating Dairy Before Bed Can Give You Nightmares, Study Suggests

  • Researchers Tore Nielsen and Russell Powell surveyed nearly 400 college students to examine links between food intake and nightmares in a study published in Frontiers in Psychology.
  • This study followed earlier claims by the British Cheese Board suggesting cheese affected dream patterns, but Nielsen criticized their unpublished findings and potential conflicts of interest.
  • Nielsen’s results showed a strong association between lactose intolerance severity and nightmare intensity, with unhealthy eating habits also linked to more frequent negative dreams and disturbed sleep.
  • Data revealed 43.8% of students reported dairy caused disturbing dreams, 30.8% linked sugary foods to bizarre dreams, and 18.8% associated spicy foods with nightmares, while women reported more food sensitivities and nightmares.
  • The findings suggest that modifying diet might reduce nightmares for sensitive individuals, but Nielsen emphasized the need for experimental studies with diverse populations to confirm causal effects.
