Google "mold" and "Norfolk Navy housing." Also lots of pollen, algae. On the beach in VA Beach may be OK, but much of area is off the James River and tributaries, and in a hurricane flood zone.
Locals hate summer and 2cd floor apts. that roast. I lived in a cheapo for 6 months; 'could sense the dampness before I first unlocked the door. Never tested it for mold, but highly suspected spores + heat + cigarette drift + overdose of hypertensive meds (Marshall protocol doc) + dehydration almost killed me.
Moved to downstairs unit in same complex with no-smoking, but never had fresh air; was told th staleness was unique to my unit. Despite ditching old sofa and new mattress, it stayed that way. 'Really smacked the morning after they knocked part of the drywall out after an upstairs leak.

I'm probably not as sensitive to mold/toxins alone as to temperature (which would also affect these). D.C. summer's notoriety is well-deserved. Hampton Roads has some water breeze; zero here. Floridians have bitched to me.
I liked sunny-and-70 in $oCal. We just had a week like that here and I felt almost recovered. On contrary, while I could work here P/T fall through spring, I've spent much of daytime in July-Aug bedridden. I can normally eek out 30 push-ups (more than many people, I realize), but one night I could barely do 10. Inside, the A/C had it at 70-something, but the outdoor air was completely saturated.
Whether its toxins, spores, or simply less oxygen, all I know is humidity and I don't get along, and summer climate control in mid-Atlantic apts. can be problematic.
I may be OK with 80 while active with A/C., but if I'm still in bed 'late a.m. (the usual) on a hot day without A/C on, I'll start to cook at about 80 like a lobster. My guess is that our poor blood circulation and cytokines are in effect. And as I found, however comfy you've made the inside, what's going on outside can still cause issues.
That said, there are many times where it'll be perfectly fine outside, and I'll still be measuring 80 indoors, due to heat transfer from other apartments. In the northeast we'd crack open windows. Do that here, esp. after rain, and humidity shoots up over 50% and your computer paper will feel damp in no time. The day after that short relief, I'll usually get nailed. So there you have your mold suspect.
In sum, unless it's a squeaky-clean beach house, I can't recommend the mid-Atlantic for ME/CFS/FM/moldies. Summer's too damn hot, and most doctors other than Shoemaker, who I understand retired, are not familiar with our conditions.
Winchester VA and surrounding area has horrific levels of leaf mold starting in OCT. I have had to wear several layers of masks outside and even inside my home and any other building I go into from it coming in from the AC/Heating unit!
