How can I calm my mind before bed?

To calm your mind before bed, consider addressing the balance between your autonomic nervous system's sympathetic (fight-or-flight) and parasympathetic (rest-and-digest) responses, which may be skewed by elevated cortisol levels. Vitamin B1 can be particularly effective in mitigating excessive problem-solving and mental activity that disrupts sleep. By increasing your intake of natural vitamin B1, you may help shift your system toward a more restful state, facilitating better sleep without intrusive thoughts.
