Cold Symptoms after pool swim

I have this problem too. The health club I go to has a salt pool. I have never experienced this issue before swimming at their facility.

Neti pot after swimming.

I switched clubs to a saline pool because of this issue.  The Neti pot works, but I didn't always have it with me and when I forgot, the snot was out of control.

For me it is asthma like symptoms-tightness in the chest-wheezing and a cough. My brief little research suggests it is not so much the chlorine but poor ventilation in the pool area. This is from memory: the chlorine reacts with organic matter in the pool-hair, sweat, skin, urine etc and creates a gas (hydrogen?) which accumulates above the pool, if not properly ventilated it makes people sick.

This weekend I noted that the doors to the pool area were propped open and the air inside was noticeably less 'pool like' also my symptoms were less severe. I had taken benadryl and pseudofed in advance hoping to prevent very bad problems like I had last week. I also noticed the pool, and adjacent hot tub, were much cooler than the normal toasty 80+ degrees.

I realize this is empirical at best but perhaps a word to the pool manager about ventilation would help?
