Staying up deep into the night does more damage than most people realize. This clip breaks down how late nights can hit recovery, stress resilience, heart rate variability, and autonomic balance, and why getting your circadian rhythm right matters so much. It also gets into why thiamine is starting to come up in conversations around sleep onset and maintenance insomnia for people who are exhausted but still cannot switch off.

Most people think vitamin B1 only matters if you are clearly deficient. This clip breaks down a much more interesting idea: some people may not be low in thiamine in the classic sense, yet still need it in a therapeutic way because the body is not using it properly. That changes the whole conversation. It means the issue may not just be what is coming in through the diet, but what the cells can actually do with it.

Most people only know the classic forms of thiamine deficiency, the brain, the nerves, and the heart. But this clip breaks down the form that may be missed most often: gastrointestinal beriberi. When thiamine-related dysfunction hits the gut and the autonomic nervous system, the symptoms can show up in ways that get brushed off, mislabeled, or completely misunderstood. If the brain and gut are not communicating properly, the whole system can start breaking down.
