What causes my arms to fall asleep at night?
I think that mental states can have effects on the physical world.
Every change in your body has an identifiable physical cause, due to the links between the the body and the nervous system.
There is prior state of the neurons in your brain and nervous system that can explain why your arms fall asleep at night.
The most evident reason of night tiredness is hormonal disfunction. Hormones have influence on our mude, behaivior, strength, bone density, activeness and so on.
Threre is such a law of nature, that hormone levels are getting lower during your lifetime after 25-30. It results to malfuntions in our bodies.
Therefore, i`d recommend you to start Hormone Therapy course. Follow here, if interested: https://rxhormone.com/hgh-therapy/hgh-deficiency/
