A day at the beach is the best way to escape the scorching heat, but one Massachusetts mother discovered that it also comes with its own set of risks. She now wants to warn others.Cassini, 40, was visiting Hampton Beach in New Hampshire with her family on July 4 when her 10-year-old son Declan announced that he wasn’t feeling well.

Cassini was initially unconcerned. 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 said in a now-viral Facebook post. As soon as they began to return so Declan could lay down, he became “disoriented” and collapsed on a sunbather. He managed to rise up again, but stumbled to the ground.

“I’m pregnant and frantically trying to pick him up,” Cassini told Today. “He’s going in and out of consciousness while vomiting. And he was quite pale.”A group of women sat nearby noticed the disturbance and promptly leaped into action. Paramedics monitored his vital signs and sought to keep him awake and warm. “God bless everyone around us. “There were so many nurses,” she explained.

“After what seemed like an eternity, he was up and chatting. “We waited for him to feel better before getting him to the car,” Cassini wrote. Declan was diagnosed with hypothermia due to the 52-degree ocean water. “I had no idea that this could happen,” Cassini stated. “You think about sunburns and dehydration and all the things that can happen in the water, but I never considered cold shock.”

Now that Declan has fully recovered, Cassini wants to warn people about the dangers of hypothermia during the summer. “Just a heads-up to parents with children that don’t get chilly and enjoy being in the water. “Just because they can handle something does not mean they can handle it.” I had no clue you could develop hypothermia on a hot summer day! This is an extremely essential lesson for everyone, not just those with children.
