Greating.
First, English aren't my principal language in day to day living, it's possible then some grammatical mistakes goes in.
I've experiment some basic internal qi-gong exercices in the past few months. Regulating the breath and the mind kind of. I'm a autodidact ( i don't know the exact term in english). I've learn the theory and basic with some books of Dr. Yang.
Yesterday, I had particularly upset for some reason at my work. I isolate myself and begin normal breathing exercises to calm myself. And then try to push the tension at my middle dantian to my lower dan dian. After that, I begin to circulate this tension in the small circulation path. Of cource with the Huiyin coordination. After 15 min my angry mood dismiss and my brain feel like I take a nap of 3 hours. That's was awesome.
This night, I can't sleep no more than 5 hours. It's strange because I've a big day at work and a big week also. I drink one beer before bed... It's possible than the internal qi-gong work I've had reduce my need of sleep?
All light of your knowledge are welcome.
