Key factors for better sleep include darkness, temperature, and minimizing disturbances. Stress is a major factor affecting sleep quality and melatonin production. The vagus nerve plays a crucial role in connecting the brain to internal organs. HRV (Heart Rate Variability) is a key metric for measuring stress resilience. Biohacking allows for personal experimentation to find what works best for individual health. Mental health is increasingly important in managing stress and overall well-being. Using devices like Pulsetto can help activate the vagus nerve for relaxation. Athletes can benefit from vagus nerve stimulation for recovery and performance. Small changes in sleep habits can lead to significant improvements over time. Watch on YouTube https://youtu.be/YGxZvO67bLM Episode transcript Cheryl McColgan (00:01.07)Hi everyone.

We're going to talk about all things kind of Vegas nerve, what that even is, why it's relevant to you as a person out there listening to this. And Vitalius has a big interest in sleep and kind of a past with some things where he was super into biohacking. this is really pretty interesting. So, Vitalius, all that being said, we start by you just sharing a little bit about yourself and your background in the biohacking? And I would love to really chat about that sleep experiment you did, because that was quite impressive what you did with that. Vitalijus (00:45.603)Yeah, so before I created Pulsetto, am one of the co-founders of this company. I was working in corporate world and basically in the sleep industry.

I will explain what those things mean. And I took those things I just listed. And then, you know, I started this kind of 100 night experiment, which means that I took one thing from those 70 lists. Yeah. And then three evenings in a row, I consume this thing. And I was imagining my aura at that moment, was like, what users It was not like a scientific study,
