In cases of sand allergy, contact dermatitis of the sand itself is often to blame. According to the Allergy Prevention Organization, it’s often found in mold, seaweed, insect parts, and even pollution. As with ocean water allergies, the most common advice when it comes to sand allergies is to avoid sand altogether. But, you have other options such as showering right after leaving the beach, limiting your time in the sand, and going to the beaches with as little pollution as possible (by preventing allergies).
Sand flies, sand fleas, mosquitoes, bloodworms, and bees are some of the most common insects to look for on a beach. Very Well Health notes that allergy symptoms from insect bites can vary from severe hives and swelling to severe nausea and stomach problems. The Allergy Prevention Organization recommends simple things like using insect spray, limiting outdoor beach activities when insects are most prevalent (dawn and dusk), avoiding beach visits on bleaker days, and wearing long clothing.
You may also want to watch out for regular seasonal allergens while at the beach, such as pet dander, grass, dust mites, trees, and seafood. There’s no reason to completely avoid that beach vacation. All you need is a little preparation.
