Last week my asthma was very bad - I had to come home from work early on Monday and didn't get back into the office all week, although I did manage to work at home on Thursday and Friday. What puzzled me was that I felt fine when I got up and my peak flow readings were fine but within the hour my breathing would get difficult.
It took me until Friday to realise that I had started using a different shower gel on Monday so I swapped back to the old one and my breathing is back to normal. Now I only use Original Source shower products as they only contain natural ingredients but it appears that there is something in the Dragon Fruit & Capsicum shower gel that disagrees with me.
Just because something only contains natural ingredients doesn't mean it is good for you. After all pollen and arsenic are natural products.
