Wise advice.
I would add that one definitely does not want to use the hot tub! That is a petri dish of germs and the steam brings them right to your nose together with the cholerine to disinfect the water. Not good for the lungs! And it eats bathing suits fastI
I did aqua aerobics for 10 years, 3 times a week, and the cholerine in the pool was sometimes so strong my eyes would water. I often wonder if that damaged my lungs. A friend of mine continues to do aqua aerobics and she wears a mask in the pool.
