Taiji for Health

Hm..recently i have started to increase the frequency of my taiji practice from once a week to about 2 to 3 times a week. And strangely, the days which i wake up with a stuffy or runny nose has decreased! Just to let you know, i get stuffy or runny nose everyday before this. That is why i think it may be due to the increase in taiji practice.
I am starting to believe in the health aspects of taiji.....
