Poor Sleep's Devastating Impact on Histamine & Mast Cells #shorts

[00:00:00]Okay, here we are, back to the histamine map. And I'm going to show you like, look where poor sleep impacts so many of these same mechanisms. Same five pathways, same mast cells, same nickel arrows, but I want you to see what sleep loss does on top of all of those things.

[00:00:16]So, it raises toll-like receptor four sensitivity. It's now firing on a hotter baseline. And then also, it raises bacterial waste from your gut. It damages the cells in your gut that make the DAO, so then you have reduced DAO to break down the histamine. Sleep loss is one of the strongest causes of free radical stress, and that damages HNMT, so histamine clearance drops systemically. And then on top of that, the central effect, sleep desynchronizes the mast cells' clock gene. And that will load even more IgE receptors on your mast cells. So, they become even more reactive at the same trigger level.

[00:00:54]So, these are like three direct hits on all five pathways, plus the mast cell clock itself. This is why one bad night of sleep can come right before a flare.
