I've been taking this one hour class at my local gym once a week for the past 4 weeks. By the end of the class I have a headache. I go home and go straight to bed because I don't feel very well. I suspect that the chlorine is the culprit here. I've learned in this wellness journey that chlorine is toxic. My question is now that I have been alkalinizing, am I more sensitive to toxins? Seems that others who take the class 3 times a week are doing ok. Will a wet suit offer better protection? Also, how is it that there are so many older people that are encouraged to use this as a form of exercise when it is so toxic?
