I have never practiced yoga but I find it quite fascinating when I read about the impact of it just like you have mentioned.
I do just exercise and simple stretches to release fatigue and whatever discomfort I am feeling in the morning and it has been very effective. I agree with your thoughts about silence because it actually works for me a lot and that's when I get to reflect properly on things.
Speaking of sunrise and sunset, these two are a blessing because it definitely influences not just my body but mind as well. I don't have the best of views due to tall houses here but just a glimpse of it does the magic.
Good morning from this part of the world.
