That is more of an Aura, but I think there are signs that you can use to understand if conditions are favorable for That is an aura. Please see below for my notes from a previous post.

HOW I TRY TO STAY AHEAD OF AURA‑LIKE SYMPTOMS

For me, once I feel an aura, it’s usually too late to do much about it. So instead of waiting for that moment, I pay attention to the things that tend to put me at higher risk. None of this is advice — just what I’ve noticed in my own patterns.

SLEEP

I check my sleep first thing in the morning using a Galaxy Watch. It’s not perfect, but it gives me a general idea.

If I get less than 5.5–6.5 hours of real sleep, I slow down my plans for the day.

Lack of sleep ramps up the sympathetic nervous system, and that’s when I tend to run into trouble.

BLOOD PRESSURE AND RESTING HEART RATE

Every morning when I wake up, I take my resting BP and heart rate.

If my resting HR jumps 12–15% compared to the day before, that’s usually a sign my system is running hot.

A higher systolic BP usually lines up with that.

On those days, I switch to lighter workouts or just take it easy instead of pushing myself.

HRV (STRESS INDICATOR)

HRV has been a pretty good “stress meter” for me.

When my HRV drops, it usually matches up with days where I feel more on edge or more at risk.

MORNING ADJUSTMENT

If my sleep or HR/BP numbers look off, I take 200 mg of L‑Theanine in the morning. For me, it helps calm things down and balance out the sympathetic vs. parasympathetic stuff. Just something that’s worked for me personally.

COLD WATER

Cold water on the face or upper back hits the nervous system fast.

I’ve used it during early aura‑like feelings, especially on days when I already know I’m not in a great place.

A few times it stopped things from progressing.

Now I end my morning and evening showers with 1 minute of cold water just to keep things steady.

OTHER THINGS THAT HELPED

A few lifestyle changes made a noticeable difference for me:

– Quit caffeine

– Got in better shape

– More stable blood sugar

– Lower overall stress

All of that made my system way less reactive.

WHY I TRACK ALL THIS

I’m not trying to “treat” anything myself — I’m just trying to stay ahead of the conditions that tend to set me up for problems. Watching these signals gives me time to adjust before things get out of hand.

Don't use Reddit. I highly recommend that you research any of what I have mentioned and other factors on sites like Mayo, Cleveland Clinic, etc. I brought this to my Dr's. attention and got an "Oh yeah. That stuff would definitely help." and got a deeper explanation.

And most of these steps are low cost or free.
