There are times when you shouldn’t practice qigong.
For example, it’s not a good idea to practice when you’re emotionally upset, as it’s difficult to concentrate your mind and relax when you’re agitated.
If you’re exhausted or have a cold, it’s better to rest instead of practicing.
Don’t push yourself to do more than your body allows.
But it’s not always best, so start slowly and build up from there.
Also, you should never practice under the influence of alcohol or drugs.
