According to this researched I heard an interview with about 15-20% of the population has some level of intolerance for histamines. Having high histamine levels affect sleep. I find it interesting that it is never addressed in these common list of what to try to improve sleep. It's not rocket science managing it, just a matter of avoiding high histamine food after 5pm or so. Good sleep might be worth it.
