There’s no better way to escape the sky-high temperatures than a day at the beach, but even though the shore can provide some relief, one Massachusetts mother learned it also comes with its own set of unique dangers. And now she wants to warn others.Even though the scare happened more than a week ago, Heather Cassini said she’s still “shaking.”

Cassini, 40, was visiting Hampton Beach in New Hampshire on July 4 with her family when all of a sudden her 10-year-old son Declan said he didn’t feel good.At first Cassini wasn’t concerned. It was hot, and Declan had been playing in the ocean. “I thought the breakfast was just too much for the waves and he just needed to lay down,” Cassini wrote on a now viral Facebook post. As soon as they started to head back so Declan could lay down, he became “disoriented” and collapsed on a sunbather.Although he was able to stand back up, but once again stumbled to the ground.“I’m pregnant and frantically trying to pick him up,” Cassini told Today.com. “He’s going in and out of consciousness and vomiting. And he was so pale.”
