Doctors Reveal That Eating Onions at Night Affects Sleep in Surprising Ways

Raw vs. Cooked Onions: Timing Matters

Doctors strongly emphasize that how onions are prepared makes a big difference.

  • Raw onions at night: More likely to cause bloating, reflux, and sleep disruption
  • Lightly cooked onions: Easier to digest and less likely to irritate the stomach
  • Caramelized or well-cooked onions: Generally safest for evening meals

Cooking breaks down some of the harsh sulfur compounds, making onions gentler on the digestive system.
