Does increasing “allergy” histamine affect “wake” histamine? Do both respond to the same triggers?

I understand that histamine is used by the body as part of the immune response, widening blood vessels, etc., to aid the white blood cells in their attack. Often this ends up helping them attack perfectly innocuous foods, leading to allergy attacks.

I also understand that histamine is also used by the body in regulating the sleep/wake cycle; this is why first-generation non-discriminatory antihistamines cause people to feel sleepy.

Are these different histamines correlated with one another? Would intentionally causing an allergy attack, for instance, promote “wake” histamine, causing a person to feel more alert? (I imagine that’s a stupid idea, but in theory, would it work? I mean that it would cause a person to feel more alert because of increased histamine, regardless of any increased epinephrine levels that potentially might go along with it.)

Along similar lines, while I imagine you can’t directly measure the “wake” histamine due to blood-brain barrier issues, could you diagnose a sleep disorder by measuring “allergy” histamine and use that to indirectly determine how much “wake” histamine one has?

What is an allergy?

Is an allergy a negative response to a molecule that the majority of the population doesn’t have?

I’ve heard that people can be allergic to lactose, which the majority of people aren’t, while people aren’t considered “allergic” to poisons like bleach, which affect everyone.

Is the point of an allergy that it’s unusual for people in that population to have that reaction?

Does a vegan diet help to reduce allergy symptoms?

Several studies have shown the positive impact that vegan diet can have on gut microbiota1. At the same time several studies have shown the connections between a gut in a poor status and the occurrence of allergic reactions1,2. Can vegan diet play a role in the reduction (or elimination) of allergic symptoms? Has any study been conducted on this topic?

Question: Is my dad lactose intolerant or does he have an actual dairy allergy?

My dad is either lactose intolerant or is allergic to dairy. He told me when he first discovered he couldn’t have dairy anymore when I was a baby, he got diarrhea. Is that a sign of a milk allergy or just being lactose intolerant? What is the difference between lactose intolerant and having a dairy allergy?
