My Daughter Is A Swimmer And Was At A Meet

My daughter is a swimmer and was at a meet yesterday and the pool had been shut down so the officials dumped a ton of chlorine in the water. Kids were stopping mid race, eyes red, crying the works. Today my daughter's voice is a bit horse and she did a neti pot and said that the mucus was a bit green. She just got over having a cold and I am frustrated. Is she sick or is this just the body detoxing? We did a steam, the neti pot, hot teas with honey and lots of fluids. Hoping she will wake up feeling ok
