My anecdotal observation of seaside living is that the "fresh" maresia (sea spray) comes with cost. I used to spend a lot of time in Santos and learned that one does not store leather goods in a closet for long periods without suffering a plague of greenish mold. My brother-in-law lost numerous camera lenses to mold.
To be balanced, my interior city gets a lot of black mold on buildings where the rainwater fails to run off or dry rapidly but I don't get "closet mold" here probably because it is less humid.
I suspect that the winds (interior and seaside) carry a lot of spores and quite possibly one could be allergic to them.
My son used to react badly to arriving in Santos and we always assumed that the humid environment favored dust mites in the homes we visited. He always had his inhaler ready at hand.
This seems like a fair article on beach allergies:
I'm not a huge beach fan after trying out most of the Brazilian coast and my larger pet peeve is salt-mist corrosion. We have intermittent beach family (snow birds) that leave their more precious portable goods with us inland to minimize corrosion while they are away. They leave printers, computers, bicycles and would leave more items if they could get them here more easily. Our seaside places only get synthetic/wood chairs, aluminum or stainless steel building material.
Alan, try the article and then go find yourself an allergist. Not sure if the Ilhéus SUS has allergists but I see a number of private ones listed there. If it's causing big problems the only way forward is with the testing process.
I, fortunately, seem to have grown out of my previous sensitivity to airborne allergens (Wisconsin corn and pine tree pollens), but have become hypersensitive to most chemical concoctions (sunscreen, shampoo, perfumed detergents) and struggle to use only neutral natural products. UV protection is by way of protective clothing or simply stay in the shade. Preventing bugs is a hard one but all of our [common] sleeping places have very nice bug net bed coverings and we run diffusers (misters?) with citronella, lavender, geranium and other essential oils when bugs are present. Fans and changing out bright white lights helps too ("warm" lights are less attractive/confusing to bugs - and no lighting is even better). For crawly bugs we grind up cloves and cinnamon and sprinkle it around on the floor (or on pantry shelves around the foods some seek).
